Phase 1 of the Nisqually Delta habitat restoration was implemented in 2002 and reclaimed approximately 40 acres of pasture. A Phase 1 monitoring project was developed to assess the ecological performance of the restored and reference estuary habitats for juvenile Chinook, a species listed as threatened under the U.S. Endangered Species Act. Phase 1 restoration monitoring efforts took place from 2003-2005. Invertebrate densities at each slough were used as measures of the study site's capacity to support juvenile Chinook.
The following is a list of invertebrates identified as part of restoration monitoring:
