methodologies, there appears to be no gross differences in the spatial distributions of Z. marina within 
the Yaquina Estuary over the last thirty years. 
Figure 11.4 Comparison of the spatial distribution of Z. marina in a portion of the Yaquina Estuary 
(see inset on Figure 11.1) from 1997, 2000, and 2004. Figure shows a large contiguous 
meadow (north of channel) and a narrow fringing bed (south of channel).
