Abstract: Throughout the 19th century, seemingly endless grasslands covered the Southwest. These grassy savannas were kept in balance largely through wildfires that periodically swept through vast areas. With settlement of the West and the resulting growth in population, an increased demand for meat resulted in rangeland being used as grazing areas for cattle and sheep. Although these grasslands were excellent for this purpose, overgrazing soon became prevalent. At the same time, fire-suppression methods improved. These factors created ideal conditions for the spread of juniper and pinyon and allowed them to encroach on the rangelands, creating millions of acres of small-diameter woodlands. In turn, this encroachment, now estimated at 60 million acres, resulted in a number of ecological problems, including lowering of the water table, reduction of rangeland, severe erosion, and pollution of streams and lakes. Finding an economical use for material from these woodlands may alleviate some of these ecological tensions.
