Houston Chapter

Field Trips

The weather is supposed to be cooling off, even if it’s only cooling ever so slightly. That means it’s field trip season again! Our chapter typically offers field trips in the spring and fall. Please sign our liability waiver and photo release and email to nphouston1@gmail.com before attending a field trip. We will have paper copies on hand at the event, but it’s easiest to do ahead of time.

About the Field Trip Leader

Starting fall 2024, we are thrilled to have Andy Newman, the Chief Ecologist at The Earth Partners, leading our field trips. Andy has 15 years of experience working within diverse ecosystems for a wide array of project types. His position places an emphasis leading the technical ecological restoration of projects, managing construction and adaptive management, and helping clients meet their compensatory mitigation requirements. His background includes environmental restoration planning, stakeholder engagement, construction, planting, and ecological uplift assessment. Andy’s specialties include aquatic feature delineations and jurisdictional determinations, Clean Water Act permitting, threatened and endangered species identification and consultations, NEPA compliance, plant identification, and community classification. His favorite ecosystems include longleaf pine savannas, coastal prairies, and southern Appalachian forests.

About the Region

New Braunfels, the location of our Fall 2024 Symposium, straddles both the Edwards Plateau Ecoregion and the Blackland Prairie ecoregion. Interstate 35 divides the city of New Braunfels; its path through the city closely parallels the boundary of these two ecoregions, with the Edwards Plateau on the west side and the Blackland Prairies region to the east. The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our four host chapters (New Braunfels, Lindheimer, Guadalupe, and the Hill Country chapters) are located in one or both of the ecoregions above. However, the eastern portion of Guadalupe County also falls within the Post Oak Savanna ecoregion. Annual rainfall averages 35 to 45 inches, with higher averages to the east. A wide variety of hardwood trees are found, including several species of oaks, elms, and in the Bastrop area, loblolly pine (Pinus taeda). Grasses and forbs dominate in the open savannas, with most common grass being little bluestem. Ranching, agriculture, and fire suppression have allowed woody species to encroach on the once-open savannas.
