Texas Horned Lizard Watch

Transects

Transects are a more quantitative method for monitoring species and require a more formal survey effort. The benefits of transects are that we can convert results to density estimates and thus compare horned lizard populations at different sites.

To conduct a Texas Horned Lizard transect you need to set up a route that is at least 3 miles long. Walk, ride, or drive the route, recording all Texas horned lizards and ant beds that occur within 3 feet of your route on either side. Transects should be conducted at least three times between May and September.
