Persnickety Texas Milkweeds “May not Lend Themselves to Mass Seed Production”

Native American Seed Company is on a mission to restore the earth, one native seed at a time.

The 300-acre spread about 115 miles west of San Antonio on the banks of the Llano River just northeast of Junction, Texas, boasts 75 acres of native plants in production

for the distinct purpose of harvesting native seed.

The company’s nondescript cedar post gate opens onto a caliche drive that winds through classic Hill Country mesquite, agarita and sotol, then spills into planted rows of huisache daisy, standing cypress, gayfeather, American blanketflower and other native wildflowers and grasses.   Water pumped from the nearby Llano River maintains the verdant fields, and allows the company to grow, harvest, process, package and ship more than 170 species of native seed and 30 seed mixes nationwide.

Among the seed stock, two native Texas milkweeds, Asclepias asperula, commonly known as Antelope horns, and Asclepias viridis, often called Green milkweed, have challenged the 25-year-old seed company’s experts.  The Monarch butterfly host plants are essential to the Monarch butterfly migration, which funnels south through the Texas Hill Country each fall.  Native milkweeds are famously difficult to propagate, even for professionals. “Species in Texas may not lend themselves to mass seed production,” said George Cates, chief “seed wrangler” at Native American Seed.

Native Texas milkweeds require stratification–cold and moisture to soften up their outer shells.   They need 45 days of moist conditions, specific soil conditions, and alternate wet and dry periods.   Worst thing you can do: overwater them.  (Check out Native American Seed’s Milkweed Stratification process at this post.)

Gardeners and butterfly fans committed in theory to propagating and planting native milkweeds (and I consider myself among them) have been vexed in practice by their persnickety ways.   That’s what often drives us to plant Tropical Milkweed, the nonnative Asclepias curassavica that is easy-to-grow, widely available and the favorite of Monarch butterflies for hosting and other butterflies for nectar. While the practice bothers some scientists and native plant purists, our rationale is that Monarch caterpillars need to eat.   In short, it’s better to provide SOME host plant for migrating Monarchs than NONE as they pass through Texas.

Native American Seed and the Portland-based Xerces Society, a nonprofit organization devoted to protecting invertebrates and their habitats, hope to change all that.

In 2010, the Xerces Society approached the 18-person staff of the Native American Seed Company about establishing a partnership to restore native milkweeds to the American landscape.  Xerces had recieved a $117,000 conservation innovation grant from the USDA’s National Resources Conservation Service.   “We call it the ‘milkweed CIG,’” said Brianna Borders, project manager for the undertaking, since renamed Project Milkweed.  A requirement of the grant was that the recipients match the sum by raising an equal amount.

Project Milkweed identified several U.S. regions for milkweed seed production–California, the Great Basin, Arizona, New Mexico, Florida, and Texas. “Texas was a clear choice, arguably the most important state to the Monarch migration,” said Borders.  The $334,000 was pretty much divied up equally between the areas, she said.

Native American Seed was an ideal candidate for the project, said Borders, because of the company’s long involvement in native seed production and its opportune location on the Monarch flyway.  Founder Bill Nieman, a high school dropout who turned a trash hauling business into a successful landscaping and design firm and then into Native American Seed, has a long history as a conservationist. The company’s mission aligned perfectly with the task.

The company’s 100-page catalogue practically serves as a free native plant guide. The vivid and abundant photography, renderings of how seeds look when they sprout, and descriptive verbiage describing each plant’s soil type, sunlight needs, and other traits

offer a broad overview of the life cycle of many plants native to the U.S.   Especially entertaining is Nieman’s annual introductory letter in which he tackles topical environmental issues–from invasive plants and water waste to wind power lines.

Results for the Mlikweed Project have been mixed so far.  The program launched just as Texas entered the ongoing historic drought.  In April 2011, the milkweeds didn’t flower or produce seed (which is expected, given they are perennials).  Borders said the first seed harvest last year (2012) was “pretty modest.”The 2,400 linear feet of native milkweeds  produced 1.5 pounds of seed, which, at an average of 65,000 seeds per pound, amounts to almost 100,000 seeds.  Of those 100,000 seeds, 95% have been restratified and replanted.

“We didn’t set a target for how much seed has been produced because there are so many unknowns,” said Borders.

Meanwhile, others have tackled the daunting task of producing milkweed plugs.  Monarch Watch, based at the University of Kansas at Lawrence, launched a “Bring Back the Monarchs” milkweed restoration campaign back in 2010.  Last fall, the program got a second life here in Texas when it partnered with the Native Plant Society to recruit volunteers to gather native seed, then mail them to Kansas for cultivation there.

bring-back-the-monarchs

The milkweed restoration campaign previously used a Texas grower. Pat McNeal, of McNeal Growers in Manchaca, Texas, assumed those duties in 2012,  but said recently that Monarch Watch “had better success in Kansas where they have four real seasons.”

McNeal suggested that the best way to propagate Texas native milkweeds would be to cultivate the tubers for two years, then plant those in the fall.   “These milkweeds don’t adapt their schedules for us,” he said, adding that Texas native milkweeds don’t do well in containers.  The plants can have a two-meter long tap root making them difficult to transplant.  ”It’s like trying to grow a potato in a pot,” said McNeal.

Dr. Chip Taylor, who oversees the program, continued cultivation this year with a Kansas grower.  He said he anticipates that 25,000 native milkweed plugs will have been produced this spring.  All have been sold on preorder. Monarch Watch will soon set up  a “Milkweed Market” for retailers on its website so people can connect with growers in their area.

At Native American Seed, the battle for Texas native milkweed seed plods on.  Cates assumes primary responsibility for their production.   He joined the company in 2003 as a student intern in ecological sciences at Austin College in Sherman, Texas.  After graduating he came on fulltime in 2007.

On a windy Friday afternoon in April, Cates pointed to the dry landscape.  ”The grass hasn’t been green since 2010,” he said. With the Llano River flowing at an historic low, Cates mentioned the seed company will once again use its entire irrigation allotment, strategically watering wildflowers and native grasses, supplementing with a recently installed rainwater collection system.

A dry winter coupled with early, hot tempertures, watering restrictions on the Llano, and an unpredictable climate suggest months of hard work and frustration ahead for Cates.  But the difficulties haven’t dampened his zeal for restoring native plants with seeds.  ”A plant in the ground will produce 100x more seed than tubers,”  he said.  ”That’s where we’re at–we’re trying to grow a substantial amount of this seed material.”

Cates has little patience for Tropical milkweed, the easy answer for gardeners in the long haul of native plant restoration. “We’re all about having it right now,” said Cates.  “These kinds of conservation efforts can’t be done ‘right now.’  It takes time.”

“Every time you vote for Tropical milkweed with your dollar, you vote against this,” he said, pointing to tidy, dry rows of future Antelope horns, which had yet to sprout this year.

Cates kneeled down and dug his fingers into the soil to find root stock from the 2012 milkweed crop. “Half of what we do fails, but that doesn’t make us stop.”

How to Get Texas Native Milkweed Seeds to Germinate

Our friends at Native American Seed have been working for years on the best way to get persnickety Texas native milkweed seeds to germinate.   “Native milkweeds simply don’t do well in containers,” said George Cates, seed wrangler at the seed farm and land restoration company in the Hill Country town of Junction.  ”They require a very specific set of conditions and have an extremely long tap-root, making containerization untenable.”

Want native Texas milkweed? Start with seeds.

So what’s the solution to getting native milkweeds into our landscape?  Start with seeds.

The process has been perfected by Cates, who has germinated thousands of seeds in the last year for Native American Seed‘s customers and the Xerces Society.    Read a report about the project and the status of native Texas milkweed seed production here.   Here’s Cate’s process:

Milkweed Stratification Procedures, Courtesy Native American Seed

NOTE:  Cates insists that sterile rubber (latex) gloves be worn at all times and that containers and implements be sterile.   Otherwise, mold can grow in the vermiculite and damage the seeds.

1. Mix seeds with pre-chilled distilled water and let soak for 24 hours in the fridge.

2.  After 24 hours, pour seeds into strainer and rinse with distilled water.

3. Moisten vermiculite with distilled water, the exact quantity required varies with different media, moist but not dripping is best.

4.  Mix rinsed seeds into vermiculite using your hands, and wear sterile gloves.

5.  Seal container and store in fridge for 30-45 days at 35-45 degrees.  Remove and plant immediately if you see mold.

6.  Plant entire mixture or sift seeds out and plant in prepared seed bed when soil temps are warm (70 degrees+).

7.  Water often until germination occurs.

Soaking and washing the seeds removes natural chemicals that inhibit germination.  When the seeds are moved from the cold darkness of the refrigerator to the bright light and warmth of the sun, they are “shocked” into sprouting.  ”The stratification process is meant to mimic nature,” he said, adding that the plants likely developed this dormancy strategy as an answer to drought conditions.

Good luck with your milkweed seeds and let us know how it goes!

First Frost Often Means the End for Late Season Caterpillars, and a Next Chapter for the Intriguing Frostweed Wildflower

We’re finally getting our first frost in San Antonio, about three weeks after the typical November 21 first frost date prescribed by gardening buffs, farmer’s almanacs and the National Climate Data Center.

Frostweed

Freezing temps usually mean the end of the season for butterflies.   Just this week we’ve had several emails and posts from butterfly wranglers wondering what to do about caterpillars discovered outside–better to let them brave the elements, or bring them inside?

Brought 22 monarch caterpillars in from the cold. Some are already starting to make chrysalises. Some are still eating, and a few have “J’d” but after a day haven’t progressed. Anyone have any hints or advice? Hoping for the best and preparing.

–Tom Kinsey, San Antonio, via Facebook

I can argue the answer to that question either way, and have taken both routes.   A late stage Queen caterpillar was discovered on a milkweed plant in our courtyard this week.  She remained outside.

Considerations included my busy holiday schedule, a lack of host plant, and the probability that when she formed and later emerged from the chrysalis, the butterfly would face cold temperatures (making it difficult if not impossible to fly), little nectar, and few prospects for a mate.  What kind of life is that?

Frostweed

Frostweed is a magnet for Monarch and other butterflies in the fall, a reliable late season nectar source.  Photo by Monika Maeckle

And yet, our friend Marileen Manos Jones of upstate New York took a different tact in late October.  She convinced Southwest Airlines to fly her and a lone lady Monarch to San Antonio in early November to release the late blooming lep at the San Antonio Botanical Gardens.   No “right” answer exists to the late season caterpillar quandary.  It’s a judgment call.

The first frost of the season poses a separate natural majesty not unrelated to butterflies:  the transformation of the excellent nectar plant, Frostweed, into a beautiful ice sculpture.  I love this plant.   Such an overlooked gem.  Can’t figure out why  this easy-to-grow perennial is not sold in commercial nurseries.

In the fall, Frostweed serves as a prime nectar source for Monarchs and other butterflies.  The sturdy Verbesina virginica, with its odd square-like stalks, sports fleshy green flanges on its stems.   The wildflower produces lush white blossoms from late August through November in semi-shade that provides respite from the late summer sun.   The flowers bloom in big colonies along the rivers and streams of the Texas Hill Country.

Along our stretch of the Llano River, Frostweed lines the riverbanks.  This last year took a toll on the flowers, as the water table had receded significantly from the 2011 drought.  Many Frostweeds died as stiff stalks in August.

But in general, this plant is gorgeous, drought toleranat, a generous seed and nectar producer, and the butterflies love it.

As a member of the aster family, Frostweed  can reach six-eight feet in height in a good year. Upon first frost, the stem splits, the sap oozes out and freezes to form fascinating curled ice ribbons and intriguing sculptures. That’s why it’s called Frostweed, or sometimes, Iceweed.

Frostweed Seed

Only a handful of species commonly exhibit this behaviour, according to Dr. James Carter’s website.   Dr. Carter coined the term, crystallofollia, to describe the phenomenon, from the Latin crystallus, ice, and folium, leaf.   Dr. Carter also points out that “the ice formation far exceeds the amount of moisture from sap locally available in the stem, and must be augmented by water drawn up from the roots.”   Frostweed’s rhizomes help it slurp up moisture in the soil to produce the ice formations.  The robust root system also makes it easy to propagate the plant from its roots as well as from seed.

For a fascinating blow-by-blow of what actually occurs botanically in the forming of these sculptures, see Bob Harms’ Biophysica of Crystallofolia website.   It humbles the most talented artist.

Winds from the South Stall Migrating Monarch Butterflies on the Llano River in the Texas Hill Country

Hundreds of Monarch butterflies were stuck in a holding pattern this weekend along the Llano River as 20-mile-per-hour wind gusts postponed their journey south.  We observed several small roosts and many clusters.   All were holding tight to pecan tree branches or seeking refuge in the low persimmon trees hugging the Llano’s limestone cliff embankments when not battling the winds in their attempt to move south.

Paddling my kayak into the wind made me even more sympathetic than usual to their travails.    It sure helps if the wind is on your side, and this weekend it wasn’t.

My husband Bob Rivard and I tagged more than 130 Monarchs in 24 hours. The insects’ orange-and-black coloring made them perfectly camouflaged in the autumn colors of the pecan tree leaves–even more so in dappled afternoon light.

Bob Rivard Tags Monarch Butterflies on the Llano

Bob Rivard tags Monarch butterflies on the Llano. Bob won the Big Swoop contest this weekend with 12 in one net.

While Monarch butterflies were ubiquitous, their numbers appeared drastically reduced compared to years past.

How to tell?   Usually, we see clusters of hundreds.  This year it was clusters of 10s and 20s. Usually, we can snag 20 or more in one lucky swoop of the net.  This year, the record (hat’s off to Bob), was 12.

Monarch butterflies hold onto a pecan tree branch

A common pose on the Llano this weekend: Monarch butterflies hang on tight to a pecan tree as winds from the South stall their migration.

Of the hundreds we saw this weekend, only one Monarch butterfly was spotted nectaring. Usually dozens of Monarchs break from their flight in the late afternoons and evenings to fuel up on abundant Frostweed or Goldenrod.   Not this year.  The insects seemed hell-bent on moving south.

Trolling up and down the banks of our stretch of river, we spotted the tenacious flyers fighting the wind, pushing into its gales, only to be forced back with a wind gust and advancing only a few yards south at a time. As Sunday afternoon rolled around, we found ourselves netting Monarchs tagged on Saturday, thus making the case that their efforts to move south were stymied.

Our weekend resembled that of Jenny Singleton, a fellow Monarch butterfly fan who had a similar experience one week prior only  30 miles northwest of us in Menard.  ”We tagged 450 over three days last weekend (Oct 11-13),”  Singleton wrote in an email to the DPLEX list, a list-serve that reaches hundreds of Monarch butterfly enthusiasts and scientists . “There was a strong SW wind all week which kept the little guys in the trees for four days and made it easy for us to observe and tag.”

Cocoa patrols the "Monarch Spot"

Cocoa Rivard patrols the riverbank we call “The Monarch Spot,” a favorite resting and roosting area for migrating Monarch butterflies on the Llano River.

Singleton relayed that at another nearby ranch, along a spring-fed creek, a team tagged 125 Monarchs in an hour in the middle of the day. “All seemed to be roosting, very few were nectaring.”

While nectar sources have been depleted because of the drought, Frostweed, Poverty weed, purple aster, goldenrod, water hemlock and other late season bloomers awaited Monarchs’ this weekend,  But they didn’t seem interested.

A strange year, hopefully an aberration, but I fear that’s not the case.

Chasing Monarchs on the Llano River with Dr. Chip Taylor, Champion of Monarch Butterflies

With overcast skies and falling temperatures last Saturday, Dr. Chip Taylor and I sneaked out of the Native Plant Society of Texas annual conference in Kerrville to chase Monarch butterflies on the Llano River.   Dr. Taylor had made a quick trip to Texas from the University of Kansas, Lawrence, to address more than 280 NPSOT members on what we can do about the threats to native milkweeds and the Monarch butterfly migration.

Dr. Chip Taylor, Founder of Monarch Watch

Monarch Watch founder Dr. Chip Taylor on the Llano River in the Texas Hill Country

His prescription:  cultivate seeds, plugs and plants of more native milkweed species through a Texas version of Bring Back the Monarchs, an innovative prairie restoration program that NPSOT is importing from Kansas.  Why the Texas focus?  ”It’s the most important state.  Spring conditions in Texas determine Monarchs numbers,”  he told the NPSOT audience.

In NPSOT’s joint venture with Monarch Watch, local volunteers like Texas Master Naturalist Cathy Downs and Monarch Watch Conservation Specialist Skip “Kip” Kiphart will organize others to help collect native milkweed seeds and share them with approved growers for cultivation and distribution.   “Last year we had a small version of this program,” said Bill Hopkins, a NPSOT volunteer, adding that the program is in the formative and fundraising stages.

Taylor’s 50-minute talk followed a presentation by hydrogeologist William “Feather” Wilson, President of Strata Geological Services, detailing the serious water challenges our region faces as the Texas population booms and drought persists. These two sobering talks on climate change and environmental challenges were about as much as I could take on a Saturday morning after only one cup of coffee. I was ready for an escape.

“Wanna go to the ranch?” I asked Dr. Taylor.  “Let’s go,” he said.

Taylor and I have spoken, emailed and corresponded many times over the past five years, but this was my first chance to meet one of my Monarch butterfly heroes:  the founder of Monarch Watch.   Anyone who follows the Monarch migration or tags Monarchs has heard about and seen photos of the feisty 75-year-old, whose signature scruffy white beard and blazing blue eyes call Santa Claus to mind.

The prospect of tagging Monarchs with Dr. Taylor presented a slightly stressful situation for me.  Monarch tagging has a lot in common with fishing in that you just never know if they’ll show up.   And even if the flighty insects make an appearance, they might not be accessible for netting and tagging.  My hope was that Dr. Taylor, having traveled so far, would have a satisfying Monarch butterfly experience.

The cool weather, a north wind and the timing of our spontaneous outing in the middle of our peak migration period gave me hope that we would see Monarch butterflies.   A text message from my friend and Monarch scout Terry Pittsford in Menard–“Monarchs flying all over Mason County!”–stoked my cautious optimism.

Small roost of Monarch butterflies on the Llano River, October 5, 2012

A small roost of about 200 Monarchs gathered in a pecan tree on the Llano River to the sage delight of Dr. Taylor.

The one-hour drive from Kerrville to our family’s Llano River ranch was a revelation for Taylor.   He said the outing gave him a greater understanding of our precious Texas Hill Country. That some Texas highways allow speed limits of 80-miles-per-hour caught him by surprise.   As he followed my decade-old Toyota Four-runner in a brand new Highlander rental, he seemed slightly flummoxed at the quick pace we were tracking on the winding Hill Country back roads.  “You always drive that fast?”  he asked.  “Dr. Taylor, you’re not in Kansas anymore,” I reminded him.

At our gate just yards from the Kimble-Mason county line, the outside temperature read 58 degrees.   “I’m not seeing any,” I said, in an attempt at expectation management.   But of course, wise Dr. Taylor didn’t need his expectations managed.   He knows well the elusive and unpredictable tendencies of Monarch butterflies.

Following a tricky crossing of the Llano’s slippery limestone bed, Taylor and I walked the pecan grove along the riverbank where Monarchs typically roost each fall en route to Mexico.   Around 4:30 PM, we noticed about a dozen Monarchs wafting high among the pecan branches.  Then Taylor identified a cluster of about 200 gathered in two high limbs.   “Here they are,” he said matter-of-factly.

As a north wind blew in, more Monarchs took up the roost.  Taylor couldn’t help but crack a wide grin.

Dr. Chip Taylor takes in the scene of the Llano River bottom where pecan trees invite annual roosts of the migrating insects.

“It’s always  fun to see Monarchs in a new area,” he said later, adding that he’s only tagged a few hundred Monarchs in his time.  ”I usually leave that to others to have all the fun.  My job is to organize and harvest the data.”

Always the curious student, Taylor took in the scene, remarking on our karst limestone formations, marveling at the Llano, the “last wild river” in Texas,  quizzing me on native plants, and observing a fresh hatch of Lycid beetles–first mistaken for a moth—on a nearby bloom.   We tagged only three butterflies in our 45-minute sojourn.  The roosting bunch was out of reach.

Dr. Orley “Chip” Taylor is a walking case study in adaptation.  With his hefty Monarch butterfly reputation, one would assume that butterflies have been his life’s work.  Not so.  He didn’t start Monarch Watch until 1992.

Lycid Beetle

Working toward his PhD in zoology at the University of Connecticut, Taylor studied insect ecology and population biology extensively.  He realized as he finished his dissertation in 1969 that he was seriously allergic to the orange and yellow Sulphur butterflies that were the subject of his dissertation.  Such reactions are not uncommon for scientists, Taylor said.  By 1972, ”I grew seriously asthmatic, and was having to take prednisone every day,” he recalled.  “I knew I had to stop.”  And by 1973, he did.

He switched his scientific focus to honey bees in 1974.   More than two decades later, he determined that to secure funds to continue studying the creatures, he would have to move into molecular biology, a field that didn’t interest him.  That’s when he turned to Monarchs.   “I’ve morphed twice,” he said.

Taylor founded Monarch Watch when he was 55 years old–an age when many of us consider retirement.  The organization has done more to enlighten the world about the unique charms and challenges of the Monarch butterfly migration than any other, and with the recent release of the film, “Flight of the Butterflies”  Taylor senses a tipping point in public awareness.   Forty-five percent of the profits from the IMAX movie will be channeled to Monarch  conservation, he told NPSOT members during his talk.

The organization, like its founder, has adapted its focus.  It began with an exclusive focus on Danaus plexippus, but has evolved to become a conservation organization—an inevitable outcome of embracing the life cycle of the Monarch butterfly.  That’s fine with Taylor, who sees the Monarch’s plight as a siege on all pollinators and the ecosystems that sustain them–and us.    ”Our human welfare is being negatively affected,” he said, adding that in some locations in China, ecosystems are so degraded that apple trees must be pollinated by hand.

Taylor’s NPSOT presentation focused mostly on the myriad threats to the Monarch migration, but he ended the serious overview on an upbeat note.   Recently he rallied his resources to help turn a former chemical recycling facility and Superfund site into a living pollinator laboratory and demonstration garden.  Taylor designed the site himself, to include butterfly, Monarch, honeybee, and pollinator gardens at the former CCI chemical recycling plant in Olathe, Kansas.  More than 100 volunteers  joined Taylor and others last month to install the plants that will comprise these gardens.  “We planted 1,600 plants in 55 minutes,” Taylor said proudly, adding that all were native to eastern Kansas.

When he’s not traveling as a Monarch butterfly champion, Taylor still teaches at the University of Kansas at Lawrence.  ”I teach one course:  the World of 2040,” he said.  ”It’s a seminar in which students have to research what the world will be like in 27 years and it scares the bejeezus out of them.”

He still grades papers, leads several professional development classes, and spends time with his wife  of 49 years, Toni, now retired after many years working in the library system at the University.   His two grown daughters obviously make him proud–Robin works as a consumer reporter for a television station in Pittsburgh and Wendy pursues a career in public health.   Between three grandchildren,  a beloved Golden Retriever, Chugaah, who he named after the Chugach Mountains in Alaska where he manages an annual fishing trip, life is busy.

We raced back to Taylor’s rental so he can leave the ranch and return to Kerrville in time for a dinner, and before deer crowd the roads at dusk.  ”Ever ever think about retirement?” I asked.  “I’ve thought about it,” he said.  ”But I just have too much to do.”

Banner Butterfly Year Caused by “Ecological Release” in Texas, says Monarch Watch Founder Dr. Chip Taylor

Texas has been called the “most important state” to the Monarch butterfly migration by Monarch Watch founder Chip Taylor.   Now our Lone Star State is getting attention for spawning an “ecological release” that has resulted in a butterfly “season like no other,”  Taylor told the Hornell Evening Tribune in New York.

Banner year for butterflies, thank you, Texas!

Banner year for butterflies. Thank you, Texas!

“This year continues to amaze,” Dr. Taylor wrote to the DPLEX email list, well-read by hundreds of academics, enthusiasts and others who follow the Monarch butterfly migration.   Taylor detailed ample and early sightings of Monarchs, Sulphurs, Red Admirals, Buckeyes and other species to the Midwest.   Watch the video above for examples.

Taylor and others attribute the 2012 banner butterfly year to a perfect storm of circumstances in Texas, including:

  •  An historic drought which killed butterfly and caterpillar predators, notably fire ants, followed by
  • Generous, well-timed rains, a mild winter that caused host and nectar plants to flourish, and caterpillars and butterflies to thrive.

Eventually, host plant and nectar populations will drop back to normal, as will this year’s butterfly explosion.

In the meantime, enjoy the show.

Wings Over the Hills Nature Festival in Fredericksburg to Celebrate Butterflies, Bats and Birds this Weekend

Fredericksburg’s Wings Over the Hills Nature Festival takes place this weekend and brings a welcome respite from San Antonio’s 10-days of Fiesta.  Just a one-hour, wildflower-loaded drive from San Antonio or Austin, the event celebrates the unique winged wildlife of the Texas Hill Country.

The festival provides 72 hours of nature-oriented education and entertainment.   Guided nature walks, butterfly, birding and bat presentations, a raptor display, and a Star Party on Saturday night at a remote ranch that brags a 360-degree skyscape unsullied by light pollution, fill the three-day schedule.

I can’t wait.   Even though I’ll be presenting two talks on Monarch butterflies, I plan to grab a seat at award-winning nature photographer Rolf Nussbaumer‘s nature

I'll be talking about Monarch butterflies at the Wings Over the Hills Festival this weekend.

photography class, Ro Wauer‘s overview of Hill Country butterflies, Diane Oegard’s talk on bats, and James Laswell‘s presentation on dragonflies.  Early Saturday and Sunday mornings, birding, butterflying and dragonfly “chases” take place, guided tours held at Ladybird Johnson Park and other outdoor venues.

On Friday at 6 PM,  Master Falconer John Karger of Last Chance Forever, Birds of Prey will do his raptor show at the Fredericksburg High School Auditorium.   Karger helped me celebrate my birthday a couple of years ago by releasing two Coopers Hawks at our

John Karger, Last Chance Forever

place on the Llano River.   The raptors had tangled with an electrical line and were injured, unable to fly until Karger’s organization nursed them back to health.  I’ll never forget them perching momentarily on my leather-gloved forearm before they took flight.  Now whenever I see Coopers Hawks soaring over our stretch of the river, I assume they are my birthday raptors.

Karger’s work is laudable and his show starring rehabilitated owls, falcons, hawks, vultures and eagles unforgettable.

The Star Party on Saturday night, 9 PM, should be spectacular.  Anyone who has ever visited the McDonald Observatory’s weekend Star Parties in West Texas can attest to the majesty of a completely dark sky twinkling with millions of stars you’ve only seen in photographs.   Shooting stars are practically routine in such circumstances, so if you attend, bring your wish list and make a wish.

Members of the Fredericksburg Astronomy Club will be on hand with telescopes,  orientation talks and explanations of the constellations and satellites.  It should be a great time to see Venus, which is staging its last transit for more than a century before crossing the face of the sun on June 6. According to the stargazing website Stardate,   Venus will be at its most brilliant this weekend, “shining 20 times brighter than the brightest true star in the night sky.”

Organizers have done an excellent job breaking up the programs, field trips and events so visitors can partake at their own pace, picking and choosing all or some of the offerings.  A weekend pass goes for $40 and provides entry into many events;  day passes $15.  Star Party, raptor show, motor coach tours and photo class are separate, and some don’t require a festival pass at all.   For details, see the Wings Over the Hills website.

Timely Rains, Pent-up Seed Bank, and Little Competition Raise Hopes for a Banner 2012 Wildflower Season

Major rain fell on San Antonio, Austin and in the Hill Country this week, raising levels at streams, aquifers and rivers in Central and South Texas and hopes for a 2012 wildflower bounty this spring.

Austin Bergstrom Airforce base saw a record 5.66 inches.  In San Antono we logged almost three inches–2.94 to be exact.  Out on the Llano River in Kimble County, about an inch-and-a-half doused the landscape.

Will steady rains in Central Texas convert to banner wildflowers in 2012?

Wildflower and butterfly fans are keeping track.  The historic Texas drought continues, yet steady, periodic rains this winter have the capacity to convert a pent-up seedbank–the soil where seeds drop and await optimal conditions for germination–to a spectacular  wildflower show this spring.

The drought’s kill-off of grass, trees and forbs also make for less competition for hearty native bloomers.   Early risers like bluebonnets, pink evening primrose, and Cowpen Daisy already dress the landscape with rosettes and eager seedlings.

Will 2012 offer a bounty of blooms and butterflies?

“So far, so good,” said Dr. Mark Simmons, an ecologist and Director of the Ecosystem Design Group at the Ladybird Johnson Wildflower Center in Austin.  ”Wildflowers need a pulse of rain every four-six weeks.   We’re on track.”

Dr. Simmons counsels cautious optimism. The caveat: invasive species also lurk and will aggressively compete for available soil, nutrients, sun and water.

Andrea DeLong-Amaya, the Wildflower Center’s Director of Horticulture, also offers encouraging words. “We’re looking to a pretty good spring….alot of germination out there, lots of good well-spaced rains,” she said. “Where cedar elms were growing before, the seed banks underneath have an opportunity.”

Three-plus inches of rain in San Antonio:January showers mean springtime flowers--and butterflies--on the Mission Reach.

The drought also stunted many wildflowers and inhibited their seed production last year, David Rodriguez, Bexar County Agent of the Texas Agrilife Extension Service points out.   “Wild populations are going to take a while, but seeded populations started in September-October are looking really really nice,” he said.

The National Weather  Climate Prediction Center is predicting “persistent” drought at least through April 30.  Given the inaccuracy of longterm weather forecasting, we’re keeping a hopeful watch.

State of the Monarch Butterfly Migration in Two Minutes: Thank you, Mike Quinn of Texas MonarchWatch

Our good friend Mike Quinn, an entomologist in Austin, Texas, who devotedly tracks the Monarch butterfly  migration and other insect activities (especially beetles) succinctly summarized the State of the Union of the Monarch Butterfly Migration this week on KXAN-TV Austin.  The two-minute clip, set partially at the Ladybird Johnson Wildflower Center, focused on the impact of the Texas drought and was picked up by the AP, the Weather Channel, and CNN.

“It’s like running a transcontinental marathon and then having a baby at the end,” the Texas  Monarch Watch coordinator and former statewide entomologist for Texas Parks and Wildlife tells the reporter.

Well put!

The article was even translated into Spanish:

Sequía en Texas afecta migración de monarcas.

Mike joined our Monarch Butterfly Texas tag team when we toured the drought-stricken Hill Country last month with the legendary Dr. William Brower, snapping professional quality photographs along the way and sharing with the world via social sharing sites.

As a passionate butterfly enthusiast, I often turn to Mike for a scientific perspective which he always generously provides.  Mike also serves as president of the Austin Butterfly Forum where he helps recruit first-class speakers such as world-renown caterpillar expert Dr. David Wagner who then avail themselves to Austin audiences with understanding, knowledge and really fun field trips.

Thanks for all you do for the butterflies, Mike.

Texas Drought Impact on Wildflower Seed Production Cuts Both Ways, PLUS Five Tips for Collecting Wildflower Seeds

First frosts lighting on Central Texas this week and reports of Monarchs and other butterflies on the wane kindle dreams of next year’s butterfly gardens and meadows. To get a jump on next year’s butterfly hostplant and nectar haven, start by collecting seeds from the wild now.  November is the perfect time to gather seeds.

Last year we wrote about collecting seeds from the prolific Cowpen Daisy, one of my favorite wildflowers.  Those seeds, Verbesina encelioidesm, are more scarce this year thanks to the historic Texas drought–just look at the recent picture above taken at Lucky Boy Ranch on the Llano River compared to the one below snapped last fall. Both reflect the same stretch of dirt road.  What a difference a year of historic drought makes.

When it comes to seed production in the face of drought, not all plants respond the same way. ”It’s a strange thing,” says  George Cates, “seed cleaner extraordinaire” at Native American Seed, a company based in Junction, Texas, that focuses exclusively on native American seeds.   ”Certain species are very well adapted to drought conditions and actually produce MORE seed during drought,” he says.

Cates suggests that the seeds of more drought adaptive plants often seem less desirable to consumers–the poisonous purple nightshade, ornery white prickly poppy and the invasive King Ranch bluestem.

Less adaptive plants die back during the drought exposing soil to the seeds of plants that are warm season dominant, creating an opportunity for more adaptive plants’ seeds to exploit the opportunity. (One of the primary reasons wildflower seeds fail to germinate is a lack of contact with soil.) ”As the ground stays crispy and cooked, other things can take advantage,” says Cates.

Plants seem to exhibit native intelligence, says Cates.  “Somehow the plants know that now is a good time to make more seeds,” he explains, adding that American Native Seed’s gayfeather crop produced more abundant seeds this year than last–even though less rain fell and the native seed farm was forced by water restrictions to discontinue irrigation early in the summer.

Cates says that seeds produced in a drought likely will demonstrate longer periods of dormancy and may take longer to germinate as they await optimal conditions.

Here’s five tips from Cates on collecting wildflower seeds:

1. Try to assess whether the seed is viable.  A microscope is ideal for this, but if you don’t carry one on your nature hikes, Cates recommends selecting samples from various parts of the plant and squeezing a few seeds between your fingers.  Look for the hard germ core as well as softer, latent matter that surrounds and protects the seed.

2. Cut the stalk of the plant if possible and hang upside down for plant nutrients to bleed into the seeds until fully dry.

3.  Don’t feel you have to clean all the fluff and chaff off the seeds.  “There’s nutrients in that latent material,” says Cates.  Just keep the material dry.

4. Store seeds in paper bag until completely dry.  If you opt for plastic bags and store damp seed material, seeds will rot.   Dry seeds=important.

5. Don’t take every last stalk of seed.  Plan ahead and leave some for next year.

Good luck, and please let us know how it goes.
