with homes further to the west. There is a walnut orchard just east of Pock Lane to the east and a community center north of the site. VEGETATION: Habitats in the site are highly disturbed from intensive farming for decades and periodic disking and tilling of portions of the site for several years (see photographs in Attachment C). The fields north and south of Duck Creek had been disked within a month or two of the surveys. The California annual grassland series (Sawyer and Keeler -Wolf, 1995) best describes the vegetation in the site. Wild oats (Avena sp.) is the dominant grass in the site, with lesser amounts of ripgut brome (Bromus diandrus) and perennial ryegrass (Lolium perenne). Other grassland species such as Russian thistle (Salsola tragus), black mustard (Brassica nigra), field bindweed (Convolvulus arvensis), alkali mallow (Malvella leprosa), and filaree (Erodium botrys) are intermixed with the grasses. Table 1 is a list of plant species observed in the site. Vegetation within and along the banks of Duck Creek include common hydrophytic species such as cattails (Typha sp.), tall flat sedge (Cyperus eragrostis), golden crown grass (Paspalum dilatatum), Baltic rush (Juncus balticus), and curly dock (Rumex crispus). There is a relatively large ornamental pine (Pinus sp.) and a few small nut trees just north of Duck Creek. Other trees in the site include a row of large ornamental trees in the northwest part of the site along Loomis Road; it is unclear if these trees fall within the site boundary or are just off-site. Similarly, there are a few trees along the road shoulder of Pock Lane on the east edge of the site and it is unclear if these trees are within the site boundary. Trees along Pock Lane include small almonds, valley oaks (Quercus lobata), and a few ornamental species. Lastly, there are several trees associated with the community center just north of the site and within residential parcels adjacent to and in close proximity to the site. No blue elderberry (Sambucus nigra ssp. caerulea) shrubs were observed in or adjacent to the site. 3009 Pock Lane: Biology 7 November 24, 2021
