Figure 17. Map of the 1993 invertebrates sample stations at the
Escalante Ranch study site. Communities are coded as:
BR=bulrush, OW=open water, AB=alkali bulrush, SW=backwater, and
R=river.
Invertebrate Spatial Distribution
At all stations water column and benthic samples were
collected to quantify invertebrate numbers in each strata. Water
column invertebrates comprised a greater percentage of
invertebrates in the open water and alkali bulrush communities
and benthic invertebrates comprised a greater percentage in the
bulrush, backwater and river communities (Figure 18). In
general, water column invertebrates were abundant in the wetland
communities, but were nearly absent in backwater and river
