Journal May 22-27 (a Del area) is overrun by Western Virgin's Berries. The margins of the (creek) located floodplain are covered mostly by small-medium (6'-18') black- berries, many of which are overgrown grapes. There are also some small- medium (8'-12') mosquitoes. The N. bank has mostly small mosquitoes, small willows, some cottonwood, alder, grasses and saplings. Both upstream and downstream of the creek we find a run of buttonbush & lots of that unknown feathery-looking plant. The south bank mosquitoes and blackberries are actually continuous in a fairly narrow row atop the bank bounding the floodplain with the middle riparian area some 100 yards downstream. In two places here are three 35-45' cottonwoods and some 10 willows in a line on the S. bank. At this point the mosquito and blackberry trees are substantially dryer, and with a few choices taller trees and one nice mulberry tree form a closed crusty woodland 25'-35' tall. Here the blackberries are by far the most numerous tree species. The woodland has a dense understory of an- familiar thousand species and ground cover of unknown leaf litter. There are numerous low trails through it, most of which show track & scat of colored passerine. The continuous extent of this dense thin forest is roughly: Bofecillas Creek -> [diagram] main road (20 ft wide) cleared strip 6000 sq. ft. of thin forest. The creek maintained a continuous surface flow between these two riparian areas, but the flow became sub-surface just below the thin forest. In this area, the N. bank had only small (4'-9') mosquitoes. The most degraded riparian section, appearing 30 yards downstream where the surface flow reappears, is dominated by a 40 yard narrow continuous
