DISCUSSION<br />

The present study partially fulf ill5 the need to provide<br />

descriptive baseline data for a portion <strong>of</strong> the natural resource,<br />

the' native mammals. These prel i m i nary results for seven habi tak<br />

types indicate that in most cases a rich and diverse fauna <strong>of</strong><br />

compl ex ecol ogi cal distribution exists on Open Space properties.<br />

Species are not widespread and are 1 imi ted to one or two habitats<br />

in most cases. Only one introduced (European) species was<br />

encountered during the study period. The complexity <strong>of</strong> Front<br />

Range environmental conditions has pr0v.i ded sui tab1 e habitat for<br />

species from many faunal elements. The Open Space properties are<br />

representative <strong>of</strong> some <strong>of</strong> the least abundant habitat types, and<br />

those most likely to be developed elsewhere in the region. In<br />

particular the foothi 11s scrub habitat type is the principal<br />

habitat <strong>of</strong> most <strong>of</strong> the Chihuahuan species (Armstrong and Freeman<br />

1984). The uniqueness <strong>of</strong> Open Space properties makes their<br />

stewardship an important responsibility; they are more than just<br />

a local resource, they are a distinctive part <strong>of</strong> our national<br />

heritage.
