Week Eleven: Wildflowers and digital cameras



Judy and Marvin Bloomquist (far left and middle) welcomed us to their home near Kingsland for our last Master Naturalist class.


I use a digital camera a lot when blogging about our Texas Wildscape. In 2008, I started Window on a Texas Wildscape as a way to document what we’d planted in our yard and the changes we saw season by season, year by year.

Little did I know that I’d branch out to citizen scientist contributions (Lost Ladybug Project), reporting a new butterfly species in our county (Falcade orangetip) and capturing insect behaviors and infestations (Phaedon desotonis that ravaged our greenthread).

Week 11 (and our last class) of our Texas Master Naturalist training with the Highland Lakes chapter covered wildflowers and using the digital camera as a tool in the field.
We met at Marvin and Judy Bloomquist’s home, which crowns a high hill northeast of Kingsland. The couple, who both belong to our Highland Lakes chapter, have counted close to 200 species of flowering plants on their 268-acre ranch. Since forecasts predicted storms, we began our morning with wildflower walks led by Marvin and Joan Mukherjee.
 
Pat, Barbara and I joined the walk led by Joan Mukherjee, who's also a member of our chapter.

Kay held up a Drummond's skullcap that's gone to seed.


Joan showed us a Brazos rockcress that'd gone to seed.



Fred pondered the Brazos rockcress for a while.

Half an hour into our walks, light drizzle started.

Like I said, Fred pondered the Brazos rockcress for a while.

Celia, Barbara and Pat got a close-up look at a common sunflower.




Once the thunder rumbled and raindrops got bigger, then we headed inside for our classroom instruction. Our first session: “Wildflowers 101” presented by Joan. “Any time you want to learn about plants, you want to learn the families,” she stressed.

"This is my Bible!" Joan said of her hefty volume, Shinners and Mahler's Illustrated Flora of North Central Texas.

During our hour-long class, Joan passed around plants and discussed characteristics related to plant families, such as Composite (sunflower) and Solanaceae (nightshade).

Pete looks over a wildflower field guide before our next class begins.

After Joan’s presentation, Marvin talked about using a digital camera as part of our Master Naturalist studies. Over the years, he’s photographed and cataloged thousands of images taken of wildflowers and plants found on his property. 

Marvin discussed aperture setting and shutter speeds, which he adjusts on his Lumix digital camera to achieve desired effects.

A standing ovation, please, for our training program coordinator, Sammy Childers! During our final wrap-up session, Pat, a fellow classmates, said, "Wayne (another classmate) made a comment that this was the best $135 (for tuition etc) he'd ever spent, and I absolutely agree." ME, TOO! Our official graduation celebration will be Sunday, May 27.

Stock tank pond ponderings...

In July 2008, James photographed this stock tank pond at the Lady Bird Johnson Wildflower Center in Austin. I think it measures 4 or 5 feet across and 2 feet deep.
So now that James has graduated, we're contemplating a new project....a stock tank pond in the back yard. We've ordered a 3x2-foot galvanized round tank, which should come next week. I've studied Pam Penick's "How to make a stock-tank pond" post on her Digging blog and will post our own photos, too. Stay tuned!

The Texas dandelion


I've been wanting to shoot some photos of the Texas dandelions that are blooming in abundance right now.





More on the blasted beetles

What's left of one of two coreopsis in our back yard.
Oh, perish the day last month when I first laid eyes on thousands of metallic brown beetles (Phaedon desotonis) that covered our greenthread in the Meadow! Since April 9 (and likely days before that), they've marched across what was to be a beautiful sea of flowery gold this spring and decimated the greenthread, both plants and blooms. 

From there, the incorrigible fiends crossed land barren of greenthread to find and latch onto two coreopsis plants in our Wildscape. Yesterday, James tried spraying deer-resistant mist on the plants. Then he sprayed soapy water. Awhile ago, I just happened to discover that the beetles have taken refuge on the underside of live oak leaves on the ground below. 

Oh, ye dratted insects of ill repute, BE GONE BE GONE from our peaceable habitat! I hereby banish you forever from our Wildscape! Alas, more coreopsis plants live on the OTHER SIDE of our back yard. Several beetles have made their way over and found them. Argh! How do they DO THAT?

I found LOTS of beetles on leaves and will likely find more.

My method of attack is to find the beetles (on the foliage and now on oak leaves) and drop the beastly invaders into a big bowl of soapy water.



Yesterday, I found this bug (Perillus splendidus) EATING one of the beetles.
So CAN we get rid of these destructive beetles? Ed referred me to Bart Drees, a professor of entomology and extension specialist with Texas AgriLife Extension Service and Research. Here's what he advised:

"Sheryl, The larvae look like some species of leaf beetle (Coleoptera: Chrysomellidae) similar to the yellow-margined leaf beetle or one of the flea beetles. It also looks like the damage may be beyond trying to save the plant leaves. Organic remedies for beetles used to include rotenone sprays, but few rotenone products remain. A strain of Bacillus thuringiensis called 'San Diego' has efficacy on beetles. Insecticidal soap spray may eliminate small, early instar, larvae. However, high pressure water spray could also knock of the larvae temporarily. See http://LandscapeIPM.tamu.edu."

We have a sample of the beetles and larvae ready to give entomologist Ed Riley at Texas A&M University. "I would like to place vouchers for your observations in the TAMU Insect Collection," he wrote me. "I suspect we will not see numbers of this beetle like this again or maybe only for the next few years."


UPDATE JUNE 7, 2012

The greenthread survived and rallied! This past week, the plants have been blooming in profusion. On a side note, I found two or three dormant beetles under leaf debris in back yard beds Sunday, June 3. Darn!

Week Ten: Mammals and range management

Welcome to Oatmeal, Texas!
Oatmeal Community Center
In my former life as a state park manager’s wife, we often encountered wildlife in the parks where we lived. Around the house or on evening walks, I might spot armadillos, foxes, deer and raccoons. A few I got to know personally. That’s because early in our marriage, my then husband brought home (on separate occasions) two orphaned babies: an opossum and a raccoon.

Fortunately, they arrived in that order. Because if the ’coon had arrived first, I’d have said NO to every baby animal thereafter.

We raised Oblio the opossum (named for the main character in Harry Nilsson’s fable, The Point!) until he grew old enough to release back into the park. Not so the raccoon. Lotar (the genus name for raccoons) was such a rascally handful that we took him to a wildlife center in Austin.

Lotar almost ruined me for motherhood. But I changed my mind later and had my two kids. Which (in a roundabout way) leads me to...

Week 10 of our Texas Master Naturalist training with the Highland Lakes chapter covered mammals and rangeland management.

From Marble Falls, we drove 25 or so miles to a teeny-tiny community called Oatmeal, which I’d heard of for years but never visited. The oatmeal box, community center and old schoolhouse seem to be all that’s left of the town. We met for our morning’s class at the community center.

Terry Bartoli, a Master Naturalist with our chapter, gave an hour-long presentation on mammals. He covered such animals as the badger, bobcat, raccoon, coyote and others.

As for white-tailed deer, Bartoli said Texas has way too many and advised property owners against feeding them. “You should have a one-buck-to-one-doe ratio (on your land),” he said. “In some areas, there are five does to one buck. That’s too many.”

“Corn is about the least nutritious thing to give deer,” he said. “Feed them protein pellets instead. If you put out corn, then you also feed rodents, raccoons and feral hogs. So corn should be used sparingly. Every time we fool with nature, we screw up other things in the process.”

Bartoli shared skulls, hides...

...and animal mounts, such as this gray fox.
White-tailed deer can be aged by their teeth.
Jim Stanley is the author of Hill Country Landowner's Guide.
Next, we learned about rangeland management from Jim Stanley, a retired chemist and Master Naturalist from Kerrville. “It’s essential that we talk about what the Hill Country used to look like,” he said. “If we don’t, it’s more difficult to understand what’s beneficial and detrimental to our property.”

Historically, “early settlers in Texas brought their cows, pigs, sheep and goats, and kept them close (to their homes),” he said. “During this time, it was the first time Texas was grazed constantly. That kept the grass short, and it also meant that succulent, high-quality grasses got hammered more often than less desirable grasses.”

Wild fires were also suppressed, which allowed woody plants to be come established in open areas. In later years, white-tailed deer grew in numbers, thanks to eradication of the screwworm, and browsed more heavily on hardwood saplings. “With the exception of cedar, that is. Because cedar is the last thing on a deer’s list of preferred food. So drought plus overgrazing and more cedar and fewer springs leads us to where we are now in Texas. All those changes have caused problems.”

The good news: modern landowners can make a difference.

“The most important thing that you as landowners can do is get an accurate, unbiased assessment about the condition of your property,” Stanley said. “Until you do, you won’t keep track of what’s going on as time goes by. I urge you to do it right away. Keep data, which will help you see what’s happening to your land year after year.”

His final advice: “Native grasses are the most important thing to have on your property, Stanley said. “You can’t have too much! Do what you can to get more grass cover.”

Inside the community center....
Our mid-day lunch break at Oatmeal's old-fashioned covered pavilion.

After lunch, we drove down the road to Indian Springs Ranch for our afternoon field excursion to look at trees and other plants.
Jerry, Fred, Pete and Dan examined some antelope horns, hoping to find monarch eggs.
Our hike begins down a rocky caliche road...
M.J. and Barbara take a shade break.
Headwaters of the Cow Creek, which feed this small lake, lie within the ranch.
Becky and Janis kept track of plant species we found along our hike.
Betty (training assistant), Eva and Wayne take a shade break. It was a HOT, sunny day!
Kay gets up high to pick some hackberry berries.
That's Sammye, our devoted training program leader (along with Becky and Celia).



Ken visits with Billy, who owns Indian Springs Ranch.
Headin' back up the trail. We're pooped!
Social time beneath the shade...Bill graciously served us barbecued pork, tortillas, sliced watermelon and drinks.
Ed's still a kid at heart.
"Hey, Wayne!" I yelled as the three left to head back to their cars.
Wayne shrugged me off, but Ed couldn't resist hamming it up for the camera.
To make room for weary hikers, Fred crawled in the very back of his wife's Toyota SUV.


NEXT WEEK

Our class curriculum AND VERY LAST CLASS takes us to the home (near Kingsland) of a chapter member, where we'll take a wildflower walk and learn about using cameras in the field. We'll also wrap up our 11 weeks of training. Graduation's Sunday, May 27!
