TPW 47: Assessing Texas Kangaroo Rat Habitat Connectivity, Management, and Monitoring Protocols
April 2021 - August 2024
- Texas Parks and Wildlife Department
The Texas kangaroo rat (Dipodomys elator) is a rare species endemic to the Central Great Plains and Southwest Tablelands ecoregions in north-central Texas. Due to substantial reduction in distribution and suspected population declines, the species has been petitioned for federal protection under the Endangered Species Act and is ranked as a G2 - imperiled (global ranking) and S1 – critically imperiled (state ranking) species. We propose a study addressing three important steps in the effort to conserve the species. First is to conduct experimental vegetation manipulations to determine feasibility and effectiveness of restoring, enhancing, or creating usable habitat for Texas kangaroo rats. Second is to assess movement patterns and dispersal of Texas kangaroo rats, especially the success of getting dispersal of individuals into restored areas from proximal occupied areas. Third is to model connectivity and environmental resistance to dispersal of Texas kangaroo rats within and among the known occupied clusters; such a model would allow targeted application of habitat restoration or creation. This project has been in a ‘pilot status’ due to delays in funding and obtaining access to private lands. We have been working on 1) identifying landowners who will allow access and habitat manipulations for this study and 2) a means to track movements of tagged animals to assess their response to habitat restoration efforts. We have contacted landowners that may allow us to start field work this fall. We are also working on a grid system to use pit tags for tracking movements of kangaroo rats rather than much heavier and larger radio/GPS collars.
