The worst year-long drought in Texas will have a lasting impact on the entire eco-system, according to wildlife biologists.

"It has a compound effect on a multitude of species and organisms and habitat types because of the way that it's chained and linked together," said Jeffrey Bonner, a wildlife biologist with the Texas Parks and Wildlife Department.

The lack of moisture will harm everything from the plants to the predators at the top of the food chain.

Since January, Texas has only gotten about 6 inches of rain, compared with a norm of about 13 inches, making it the most severe one-year drought on record.
