Learning from Nature
Making intelligent, evidence-based decisions for the conservation and restoration of the Arboretum’s landscape requires understanding both past and current environmental conditions and the efficacy of our landscape management practices. The Conservation staff conducts research to evaluate projects and guide future actions. Much of this research focuses on applied ecology, adaptive management, and ecosystem services in the Arboretum’s unique urban-wildland interface.
Current & Past Research
Invasive Species Monitoring
As part of ecological monitoring efforts, this study was conducted to assess the spatial distribution and ecological impact of Deep-rooted Sedge (Cyperus entrerianus) and to provide data-driven insights for guiding ongoing restoration and vegetation management in the Houston Arboretum’s savanna ecosystem.
This study surveyed plots within the woodland habitats of the Arboretum for individual Chinese Tallow (Triadica sebifera) trees and recorded their physical attributes and surrounding light availability to understand habitat preferences and provide location data for future management.
Long-term vegetation surveys
As part of the Master Plan, in 2015 the Conservation team implemented recurring vegetation surveys to evaluate the effects of restoration efforts and guide ongoing vegetation management.

Long-term pollinator and insect monitoring
Conservation team members, interns, and local high school and undergraduate students monitor pollinators and other insects throughout the year in five different habitats. This monitoring provides an indicator of habitat quality and productivity.
Prescribed Goat Browsing
These studies monitor the effects of goat browsing on both native and undesirable vegetation in different habitats to improve vegetation management at the Arboretum.

Prescribed fire response
Following prescribed fires, the Conservation team monitors vegetation to track recovery and identify methods to improve species diversity.
Bat monitoring program
The Arboretum established a bat monitoring program using high-frequency audio recording and echolocation analysis software. The program determines bat species presence and habitat selection within the Arboretum and compares data between seasons and across years.
Wildlife and game camera monitoring program
This ongoing study uses game cameras to document the presence of wildlife species, estimate wildlife population density, and understand wildlife use by habitat type.
Rice University SSPEED Center hydrology study
A hydrologic modelling and in situ soil infiltration study conducted by Rice University to determine the flood retention benefits of natural landscapes found in the Houston Arboretum.

Mosquito monitoring
Harris County Precinct 4 Biological Controls Initiative tracked mosquito species and introduced native biological controls like predatory nematode worms and dragonfly nymphs into the Arboretum’s ponds. Harris County Public Health used mosquito data from the Arboretum to detect potential pathogens and disease-carrying animals before they cause outbreaks in the greater Houston region.
