Abstract:

Nerodia h. harteri (Brazos Water Snake) is a state threatened endemic Texas snake found along the upper Brazos River drainage in north-central Texas. A range-wide survey was conducted from 2006-2008 to determine the current distribution and relative abundance of N. h. harteri, identify potential habitat, and investigate habitat relationships of the snake. While the range of N. h. harteri and suitable habitat remain intact, the snake is now rare. Logistic regression analysis indicated the likelihood of finding the snake was positively related to both the amount of rock (>10 cm) at a site and surrounding a site. Reasons for the population decline remain unclear; however, results illustrate the importance of riffle habitat for the future conservation of this Texas snake.
