Nature Notes explores the natural world of the Chihuahuan Desert.

How does photosynthesis actually work? Why does the wind blow? What does a venomous snake bite consist of?

Every week, Nature Notes investigates questions like these about the plants and animals of the Chihuahuan Desert region and the Llano Estacado in the southwestern United States.

Nature Notes is a 4½-minute weekly radio program produced by Marfa Public Radio in Marfa, Texas, in conjunction with the Sibley Nature Center in Midland, Texas. Nature Notes airs on KRTS Marfa Public Radio and KXWT West Texas Public Radio. Hosted by Dallas Baxter, new episodes air on Thursdays and replay on Tuesdays, and episode material is written by the staff and volunteers of the Sibley Nature Center. Past episodes were produced in conjunction with the Chihuahuan Desert Research Institute.

This environmental program examines a little-known desert region in the United States and Mexico. But many desert-dwellers featured—such as turkey vultures and prairie dogs—will be familiar to listeners outside this region. Through interviews with scientists and field recordings, Nature Notes reveals the secrets of desert life. Hide full description
