Abstract

Two natural sites in the Portland urban area, River View Natural Area (RVNA) and Powers Marine Park (PMP), were sampled to assess their insect faunal composition with the intention of determining whether the areas are sufficiently similar ecologically that they could potentially be managed as a single unit. The two areas were compared using community ecology metrics based on their respective invertebrate fauna. The results suggested that RVNA and PMP had statistically different ecological communities. The Shannon Diversity Index for PMP was 0.303, and 0.819 for RVNA. The Horn Index of Community Overlap suggested a 93.46% overlap based on these data; however, a Hutcheson’s t–test for community ecology data suggested significant differences (P <<< 0.0001) between PMP and RVNA’s insect faunal compositions.
