Anderson Hole
The floodzone at Anderson Hole (Fig. 12, Tables 2 and 3), had low total
plant coverage (Fig. 13). Plant coverage increased significantly above the
f loodline, primarily due to shrubs such as squawbush and big sagebrush. Grass
and forb coverage was also greater above the floodline. The peak in forb
density seen in Zone III was due to a band of Iva axillaris.
Of particular interest at this site were rows of cottonwood seedlings,
generally running parallel to the river in the moist sand of the floodzone.
Mature cottonwoods were present at the site and may have been the seed source.
