The Future of Arid Grasslands: Identifying Issues, Seeking Solutions
Proceedings of a conf. on the major problems facing grasslands in arid & semi-arid regions of the U.S. & Mexico & to seek solutions to those problems. Grasslands in many parts of the Southwest & northern Mexico are facing serious threats -- from urbanization & subdivision development to spread of invasive plant species to conflicts over grazing policy. Target groups for participation included private landowners, non-profit groups, government agencies, environmental advocates, economists, scientists, etc. Emphasized practical, hands-on mgmt. methods, including time in grasslands managed under a variety of techniques.

Page 256 - Our mission is to preserve the plants, animals and natural communities that represent the diversity of life on Earth by protecting the lands and waters they need to survive.
Page 291 - Our goal is to restore and maintain the natural processes that create and protect a healthy, unfragmented landscape to support a diverse, flourishing, community of human, plant and animal life in our borderlands region. Together, we will accomplish this by working to encourage profitable ranching and other traditional livelihoods which will sustain the open space nature of our land for generations to come.
Page 170 - Where you stand the grass is rich and matted, you cannot see the soil. But the rich green hills break down. They fall to the valley below, and falling, change their nature. For they grow red and bare; they cannot hold the rain and the mist, and the streams are dry in the kloofs.
Page 204 - One of the anomalies of modern ecology is that it is the creation of two groups, each of which seems barely aware of the existence of the other. The one studies the human community almost as if it were a separate entity, and calls its findings sociology, economics and history. The other studies the plant and animal community and comfortably relegates the hodge-podge of politics to the 'liberal art.
