road. The other depressions aze pits that were created when soils from the site were taken for use in unrelated projects. 2.1 BIOTIC HABITATS The site had historically been farmed for several decades and only in the last 3 to 4 yeazs did fanning cease, and since that time it has served more as a site to stockpile or borrow soils for other nearby development. Irt other words, the site has not supported a natural habitat component for several decades. For the purposes of this report, the only biotic habitat presently identified on site is "ruderal." All the vascular plants observed within this highly disturbed habitat are included in the following discussion (section 2.1.1). A list of the terrestrial vertebrates using, or potentially using, the site is provided in Appendix A. 2.1.1 Ruderal This regularly managed site is predominately comprised of baze soils with sparsely scattered ruderal and non-native vegetation characteristic of ruderal sites throughout the region. The site is relatively flat and features a short berm near the middle of the eastern half of the project site. A gravel road and a related ditch occur along the western boundary. The slight topographical variation, however, does not result in variation of biotic characteristics. Irt other words, flora and fauna would not utilize one portion of the site in a significantly disproportionate way over another. Vegetation occurring onsite consists ofnon-native annual grasses of European descent, including slender wild oats (Avena barbata), ripgut brome (Bromus diandrus), soft chess (Bromus hordeaceus), foxtail barley (Hordeum murinum), and Italian ryegrass (Lolium multiflorum). Native and non-native forbs observed in this habitat, and common to disturbed areas, include fiddleneck (Amsinclda menziesii), scarlet pimpernel (Anagallis arvensis), black mustard (Brassica nigra), bindweed (Convolvulus arvensis), redstem filazee (Erodium cicutarium), mallow (Malva sp.), bur clover (Medicago polymorpha), bristly oxtongue (Picris eschioidies), wild mustard (Raphanus sativus), milk thistle (Silybum marianum), common groundsel (Senecio vulgaris), spiny sowthistle (Sonchus riper), rose clover (Trifolium hirtum), and hairy vetch Ironwood 55+ Biotic Evaluation Live Oak Associates, Inc.
