This is the second in a series about how domestic animals like cattle can help wildlife and habitat in desert grasslands.  Our first introduced Cows and Quail, Albuquerque-based Holistic Management International’s new range and wildlife program which focused on quail. Our topic in this article is the most characteristic large mammal of far-West Texas and

It turns out that biodiversity and high
