520 | 3 |a"The Olympia oyster (Ostrea lurida Carpenter, 1864) was designated a species of Special Concern under the Canadian Species at Risk Act in 2003. A management plan was developed in 2009, and a primary objective was maintenance of relative abundance (density) at index sites. Fourteen index sites were chosen to monitor density within their range in Canadian waters. Sites have been surveyed at least twice since 2009. Density, length frequency, and bed area have been determined for sites. Densities varied across sites and years, and ranged from 507 ± 74.1 m⁻² at Port Eliza in 2013 to 0.6 ± 0.4 at Bacchante Bay in 2012. The time series at most sites is short and precluded evaluation of trends. However, baseline information from index site data and continued monitoring will enable future analysis of variability and trends"--Abstract, p. vii. |
