The explosion of geospatial technologies is providing new opportunities to explore and study rangelands at spatial and temporal scales that were not possible a few years ago. One area where these technologies are playing a fundamental role is in the monitoring of invader species and how they can potentially affect the distribution of cattle in pastures. The objective of this presentation is to provide a summary of multiple projects aimed at one common goal: the control of an invader species through management. We are integrating habitat management, fire ecology, and landscape ecology with geospatial technologies to better understand the effects of different management strategies to minimize the impact of tanglehead in South Texas pastures.  Prescribed fires are used to remove above-ground biomass and decadent growth creating palatable growth that can be consumed by cattle. Cattle are being used as a management tool, and are fitted with GPS collars (10-minute interval between locations) to assess their movement and habitat use. Unmanned aerial systems are being used to map prescribed burned areas and to quantify the changes in species and above-ground biomass resulting from the fire and pasture use by cattle. We are also using remote sensing to classify the spatial distribution of vegetation types and their temporal dynamics. All data and information are collected and integrated in a geographic information system and that are analyzed to generate new information on the spatial and temporal dynamics of tanglehead and its potential impact on pasture use by cattle.

About Research Lecture Series

The BRIT Lecture Series is designed to create community wide conversation about a diverse range of important and rapidly developing topics. This series gives scientists and speakers a forum for sharing the most current information about their areas of expertise and allows the public to interact with leading members of the local, national, and international scientific community.

Our Lecture Series is made up of Brown Bag Lunchtime Lectures and BRIT Research Seminars. Brown Bags take place the first Tuesday of each month, February – July and September – November, from noon - 1pm in the BRIT Commons. Research Seminars take place periodically throughout the year and are scheduled based on the availability of our in-house and visiting researchers.

All events are free and open to the public, please watch this page and our Facebook page for announcements of upcoming Brown Bags and BRIT Researcher Seminars.
