Rehabilitation Techniques<br />

ESTABLISHING PLANTS ON THE RANGE<br />

It may be useful to consider the practices used in range management<br />

in terms of the relationships shown in figure 7-1. By so doing,<br />

levels of range productivity cu be seen as functions of environmental,<br />

cultural, social, <strong>and</strong> political factors, as well as the availability<br />

of technology. It is important to und8llt<strong>and</strong> these factors when<br />

determining effective approaches to range rehabilitation.<br />

Extenslft Practicel<br />

Range rehabilitation techniques vary greatly. Examples of extensive<br />

practices for rangelud management are the manipulation of<br />

graing ud the use offire. These practices may require fencing, water<br />

supply development, <strong>and</strong>/or fire lines, but they generally require<br />

little muagement <strong>and</strong> do not risk the lou of the existing vegetative<br />

cover (a do some of the more intensive manipulative practices).<br />

Extensive practices are low cost, but opportunities to increase production<br />

are correepondingly limited. Other practices, such as water<br />

management, require a higher level of input than the manipulation<br />

of gruing or the use offire, <strong>and</strong> are, therefore, intermediate between<br />

extensive <strong>and</strong> intensive practices.<br />
