Abstract
Phase 2 continues the original ecoroof habitat study purpose to compare the habitat value of industrial ecoroofs designed to provide habitat with the habitat value of industrially-located ground sites in the Pacific Northwest. Both Phase 1 and Phase 2 studies found that ecoroofs designed for habitat offer the same and possibly greater value of habitat than comparable ground sites (Dobro Design 2015). The study entailed comparing the habitat value of four ecoroofs that were designed to provide habitat to two ground sites with vegetation. All sites are located in heavy industrial settings. Data was collected on average monthly over a 24 month period. Methods: From studying the basic elements of habitat such as food, water, and shelter; habitat parameters were identified and used in a matrix appraisal system for evaluating the habitat value of the Phase 2 sites. The following parameters were assessed using a rapid habitat assessment tool: Plant Type Richness, % Plant Cover, Bloom Type Richness, Bloom Abundance, and % of Visits Blooms are Present, Soil Temperature, Soil Moisture %, Insect Morphospecies Richness, Insect Abundance. Findings: Data showed that ecoroofs designed to provide habitat have higher abundance and richness of plant and insect species when compared to industrial ground sites. This among other parameters contributes to a higher value of habitat. The presentation will include a brief description of Phase I purpose and findings, a more in-depth description of Phase 2 methods, specific findings from the data collected, and a discussion of conclusions from both studies.
