The pads provided <br />perch sites where many of the birds were observed during surveys <br />but did not provide nesting habitats for foliage-nesting birds. <br />Cavity-nesting and foliage-nesting birds would be most adversely <br />affected; whereas there was little difference in ground-nesting <br />bird densities. <br />If reclaimed sites advanced to mountain shrub, bird densities <br />and diversity would be similar to interior aspen; however, <br />species composition would be different. Cavity-nesting birds <br />would be more adversely affected than other birds, although house <br />wrens were quite numerous on the mountain shrub habitats. The <br />species composition of foliage nesting and ground nesting were <br />quite different; however, the number of birds was similar. <br />
