Ground-dwelling vertebrates, birds, habitat data on the Willamette National Forest, Oregon (Young Stand Thinning and Diversity Study)

<section><para>Understanding how to maintain the ecological diversity of young managed stands is a topical
issue in forest management in the Pacific Northwest region. To begin to understand the effects of different thinning treatments on ecological diversity, the Willamette National Forest initiated the Young Stand Thinning and Diversity study (YSS). This study compares relative populations of small mammals,
Amphibians, reptiles, and birds under different thinning treatments. Tree growth and vegetation development are also examined</para></section>
