II: Marine Invertebrate Baseline to 2000 and Invertebrate-related Management Issues. Parks Canada-Technical Reports in Ecosystem Science. Table summarizes the number of Brachyura records as museum specimens from the Gwaii Haanas region. Gwaii Haanas National Park is located on the southern end of Queen Charlette Island, B.C., Canada. Approximate park boundaries are 52 degrees 45' 42.2" N and 131 degrees 53' 12.3"W (centerpoint of island) at the northern end and 51 degrees 53' 34.8" N and 130 degrees 59'17.9" W at the southern end. This region fall within the North American Pacific Fjordland ecoregion. Sloan et al., 2001
EPA Consolidated Benthic Database_Decapods_Oregon.pdf EPA Consolidated Benthic Database: U.S. Pacific coast surveys. Decapods: Oregonian. This table contains mean abundance, percent frequency and relative abundance classifications of all decapods reported from benthic surveys in the Oregonian Ecoregion. Sample totals were 555 from the Estuaries and 110 from the Ocean. Samples were taken from the intertidal to 120 m depth. Most samples were taken with a 0.1 m2 grab though some were sub-sampled due to the amount of detritus. Samples were sieved through a 1.0 mm mesh with abundances standardized to the number of organisms per 1 m2. Estuary and ocean samples were analyzed separately and the higher of the two relative abundance classes is used on the CBRAT abundance maps. Relative abundance of each species was normalized using all Decapod taxa from within the respective ocean or estuary habitat. VA = very abundant; MA = moderately abundant; HM = high moderate; LM = low moderate; MR = moderately rare; VR = very rare. Based on the formula used to calculate dominant normalized relative abundances, it is not possible to generate a "very rare" species with less than 1000 total individuals in a sample (e.g. Ocean samples for the Oregonian).

WA DOE PSEMP Database_Decapods_Puget Sound.pdf Washington Department of Ecology- Puget Sound Ecosystem Monitoring Program (PSEMP). Decapods: Puget Trough /Georgia Basin. Values represent the percent frequency of occurrence, mean abundance, and Dominant Normalized Relative Abundance (DNRA) classes for decapods from the WA Department of Ecology's Long-Term /Temporal Sediment Monitoring Program (PSEMP). A total of 1481 grab samples were taken throughout Puget Sound during annual cruises in the month of April from 1989 - present. Benthos were collected from sediment up to 17 cm in depth and sieved through a 1.0 mm mesh. Relative abundance for individual species was normalized using the total number of decapod taxa from all the grab samples. VA = very abundant; MA = moderately abundant; HM = high moderate; LM = low moderate; MR = moderately rare; VR = very rare. WADOE - PSEMP, 2015
