In addition, the site will be fragmented by roads and home sites. Remaining habitat will be in small <br />patches and will not likely be contiguous to adjacent wildlife habitat areas. <br />Native Plant Populations <br />Alternative 2 would reduce native plant populations on the site. With the same assumptions used <br />in section 4.2.2, one can expect a reduction of at least 21 acres in native dominated plant <br />communities. The mixed conifer forest communities would likely be the most heavily impacted with <br />the depressional broadleaf wetland community most likely to be least impacted. <br />However, development of the site would endanger all remaining native plant communities by <br />increasing their vulnerability to invasive exotic. species invasion. The site would likely be <br />fragmented so that all existing native plant communities would be within 50' of home sites or roads. <br />Soil Resources <br />Alternative 2 would significantly impact soil resources. It is estimated that soil disturbance <br />associated with road construction, home construction and infrastructure construction would affect <br />soils on 20-30 acres of the site. This would likely lead to increased erosion, loss of topsoil, and <br />may even lead to slumping and soil creep since the entire site has slopes greater than 10%. <br /> <br />
