The field trip on September 12, 2025, to River Ranch County Park near Liberty Hill, was attended by 22 participants and led by Ricky Linex. This field trip was a follow-up to Ricky’s presentation at NPSOT Williamson County’s chapter meeting on September 11, where he presented “Guidelines for Learning to Identify Common Grasses of Central Texas.”

Calling on his decades of service with the NRCS, as well as information presented in his book, Range Plants of North Central Texas: A Land User’s Guide to their Identification, Value and Management, Ricky is a wealth of knowledge. 

The hike covered about 1 mile through live oak-juniper savannah, where native grasses included tall grama, little bluestem, seep muhly, slim tridens, hairy grama, Texas grama, hairy tridens, and indiangrass, as well as rosettegrass, lovegrass, KR bluestem, and threeawns. Forbs included frogfruit, wooly vervain, pasture heliotrope, slender greenthread, broomweed, skeleton flower, doveweed, Drummond’s rain lilies, bullnettle, and noseburn.

Along the trail, Ricky demonstrated how touching or smelling plants can aid in identification. For example, to tell the difference between buffalograss and curly mesquite in the vegetative stage, he showed us how to rub a piece of stolon between the lips. If smooth, it is buffalograss, while stolons of curly mesquite are rough. At various stops, participants smelled crushed leaves of juniper, chewed leaves of prickly ash, or bravely rubbed leaves of noseburn on their skin. On finding bullnettle, Ricky explained how to safely collect its edible seeds. However, he cautioned that touching the leaves can be a very unpleasant experience.

At one point we stopped to study a motte of woody plants that included live oak, ashe juniper, hackberry, elbowbush, agarita, and white honeysuckle. From a wildlife perspective, Ricky explained that this dense vegetation would provide excellent cover for doves, quail, and other birds. For a land manager, such a motte could be duplicated in other areas by simply taking a shovelful of soil from under the canopy, which contains a diverse seed bank, and distributing it to other places on the property.

After the leisurely hike along the trails, the participants returned to the starting point and continued conversations with Ricky until the end of the allotted time. The field trip ended before the temperature became too uncomfortable.

River Ranch County Park includes 20 miles of hiking trails within its 1,354 acres. The trail chosen for this hike is one of the furthest from the park entrance, and less used than other trails, but was perfect for observing late summer grasses, which were still green thanks to recent rains. Although this hike covered a tiny portion of the park, the hike was a good introduction for those who had not previously visited River Ranch.

Trip Report: Godwin Ranch Preserve, August 2025

Eight NPSOT members assembled at 8 a.m. to conduct a plant survey at Godwin Ranch Preserve in Georgetown on Sunday, August 24, 2025. This was the third of four surveys we will conduct to establish a plant list for the preserve.  Nearly two inches of rain in the past week along with even more rain over the past month made for lush grass growth, although few forbs were blooming.  The early start and low humidity made for a pleasant walk through the customary loop used for this survey.  

In the two hours spent on the survey, we observed about 60 species of plants. Most were native species, but we also found invasives such as chinaberry, common hedge parsley, King Ranch Bluestem and Johnson grass. Recent moisture allowed nostoc (witches’ butter) and mosses to thrive on rocks and bare soil along the trail. We identified a number of grasses, including Little Bluestem, Silver Bluestem, Sideoats Gramma, Texas Gramma, and Heller’s Rosette Grass. Pasture Heliotrope was blooming, and we identified seed heads for Firewheel, Upright Prairie Coneflower, Greenthreads, and Beebalm. Doveweed was abundant, and a few Drummond’s rain lilies were spotted. Perhaps the highlight of the survey was finding a Rio Grande Copperlily, an unexpected find. Milkweed vines were prominent, but we so far have been unable to definitively identify the species. Native oaks, Ashe Juniper, Cedar Elm, and Eve’s Necklacepod are interspersed around the preserve, and are decorated with several species of lichens.

Late summer is not the optimal time to observe birds, but we were able to identify the songs of White-eyed Vireos and Lesser Goldfinches and spotted a black-chinned hummingbird. We found tracks for feral hogs and raccoons in the muddy trail, and scat of jackrabbits and coyotes. We also discovered a shed antler from a white-tailed deer and the skull of a feral hog. 

The fourth and final survey will be held in November.

Trip Report: Booty’s Road Park Field Trip

On Saturday, June 21, a group of nineteen people and two sociable canines gathered at Booty’s Road Park in Georgetown to hike a one-half mile section of the San Gabriel River Trail. The outing began with a plant scavenger hunt at the edge of the parking lot, where a diverse group of trees, shrubs, and vines could easily be observed at eye level. Participants were challenged to find eighteen species listed on a handout.

From the parking lot, we headed east following the concrete trail that passes through an open woodland of Ashe juniper, Escarpment live oak, and Cedar elm. The path soon transitions to decomposed granite and enters a shaded riparian woodland. Here the path is bordered by a steep limestone bluff on the left, and the North Fork of the San Gabriel River on the right. Along the base of the bluff, large boulders provide varied terrain for an interesting mix of herbaceous plants, including Turk’s cap, Toothleaf goldeneye, Roughstem rosinweed, Pigeonberry, Inland wood oats, and White avens.

Overstory trees, including Pecan, Walnut, American elm, American sycamore, and Green ash, form a high, closed canopy, while understory species include Box elder, Texas ash, Carolina buckthorn, Yaupon holly, and Roughleaf dogwood. Vines, including Mustang grape, Virginia creeper, Carolina snailseed, and Yellow passionvine were frequently seen. Less common were Pitcher’s leatherflower, Alabama supplejack, Anglepod, and a delicate Creeping cucumber.

Adding interest to the hike were several small, natural seeps that emerge from the bluff and flow under the trail through culverts, trickling down toward the river. One of the prettiest spots was a small, spring-fed pool lined with maidenhair ferns and moss-covered rocks, fed by a perennial spring higher up on the bluff. At this popular spot, the group took time to enjoy the scenery as the outflow from the pool forms a wide, shallow sheet that cascades down a rocky slope dotted with mosses, ferns, and lush aquatic vegetation. Near this spot, observant participants noticed the pink flowers of Marsh fleabane, as well as white-flowered American water willow, in moist soils along the river bank. A little past the pool, where the trail splits around some major boulders, the group observed several Rusty blackhaw, a small tree distinct for its shiny opposite leaves and dark checkered bark. A little farther on, the group turned around and we retraced our steps back to the parking lot.

While some of the participants had hiked this trail before, it was a new experience for others. On this day, the easily accessible trail was populated with hikers, cyclists, dog walkers, and families with strollers. Our group found that, even on a warm June day, this woodland trail provided a welcome respite from the rising heat.
