Adopt-a-Loop is a citizen science project by the Texas Parks and Wildlife Department and Texas Master Naturalists (TMN) to better understand the distribution of Texas’ wildlife. The Great Texas Wildlife Trails (GTWT) are used by many to visit sites across the state for birding and other wildlife viewing. (From TPWD) Download iNaturalist and eBird before you go!
