The Texas Quail Index: Hands-on Conservation

The Texas Quail Index (TQI) is a series of hands on demonstrations organized by the Texas A&M AgriLife Extension Service. It is designed to educate land managers, hunters, and others about population dynamics, habitat requirements, and other factors affecting bobwhite and scaled quail in Texas.  At the county level, TQI fosters landowner and community involvement and provides tools for interested stakeholders to assess the “quail-equation” in their community. Statewide, the TQI provides an important opportunity to use citizen-science to help monitor the abundance of quail and bring attention to their importance, plight, and needs.
That may sound abstract, but the process is actually very concrete. It starts by recruiting the Texas A&M AgriLife County Extension Agent (CEA) for a particular county to participate in the TQI.  They in turn find a ranch or other suitable property willing to serve as the demonstration site. The CEA is also responsible for recruiting other members of the team from their community. This team could be: the hunters who have a lease on the property, a former QuailMaster in the area, a former Bobwhite Brigader, a Master Naturalist, agency personnel (NRCS or TPWD), and, ideally, a member of the local media.  
These teams are responsible for collecting data on quail abundance, predator abundance, and habitat quality on the participating site. They do this by using a variety of techniques throughout the year.  To start off the breeding season, teams use spring call counts to assess breeding potential of the quail population.  During nesting season (April-October), teams will use dummy nests to estimate the impact of predators on nesting quail in the area and assess the availability of quality nesting locations (i.e. what is the density of bunch grasses and/or suitable prickly pear).  Next, teams will use game cameras to create an index of predator abundance on the property. This information can be used in conjunction with the results from the dummy nests to determine whether nest depredation may be a limiting factor on that property.  During the summer, teams will assess the habitat quality on the property using a guide that takes into account all aspects of habitat that are important to quails: food availability, woody cover, nesting cover, and water availability.  In September, teams will use roadside counts to compare how their quail populations measure up to the Texas Parks and Wildlife average for their ecoregion.  Fall covey call counts conducted in October are the last measure of the population going into hunting season and can be helpful in planning how much hunting pressure the population can safely handle.  Finally, harvest data are used as another index of abundance and a measure of production for that year by comparing the adult:juvenile ratio and coveys flushed per hour of hunting effort.

All these data collected at the county level are then submitted to a central database managed by Texas A&M AgriLife Extension Service to be analyzed on a statewide level.  By combining all the observations, we can identify patterns in quail abundance across the state or answer other questions such as the relationship between different aspects of habitat quality (e.g., nest site availability) and quail abundance. Maybe most importantly though, the TQI will get people from across the state involved and thinking about what can be done to help in their area.
As the old adage goes “The best fertilizer is the footprint of the farmer.”
