  • South Puget Sound Volunteer Opportunities - a list of organizations that offer direct hands-on opportunities to restore ecosystems.
  • Dissolved oxygen from nitrogen loading
    • In the 2008 Water Quality Assessment, Ecology found that 24 locations in South Puget Sound were impaired due to a lack of dissolved oxygen. Ecology identified another 27 locations as waters of concern. The locations of greatest concern are Carr, Case, and Budd Inlets. Fish need oxygen. In areas with low levels of dissolved oxygen, fish and other marine life become stressed and die or are forced to flee their habitat. From [1]
    • On an annual basis, wastewater treatment plants south of the Tacoma Narrows send an average of 6,000 pounds of dissolved inorganic nitrogen into South Puget Sound per day. Another 11,000 pounds of dissolved inorganic nitrogen came from all other human and natural sources in the watershed. During the critical summer period for dissolved oxygen when river flows are lower, the wastewater treatment plants are a larger percentage of the load. The area between the Tacoma Narrows and Edmonds has many more people and it contributes about four times more dissolved inorganic nitrogen than South Puget Sound. Future work will quantify the amount of nitrogen coming into South Puget Sound from the Pacific Ocean. [2]
  • Prairie ecosystems are notable in glacial outwash
  • Joint Base Lewis McCord provides a major ecological preserve under federal ownership
  • Urbanization is rapid (need strong source)
  • Nisqually Watershed is a focus of protection by multiple parties
  • Three tribal nations were signatory to the Medicine Creek Treaty which ceded tribal lands to colonization.
    • Squaxin Island Tribe includes the descendants of seven bands that were spread among the inlets of the South Sound.
    • Nisqually Indian Tribe includes the descendants of bands that lived around the Nisqually River.
  • Deschutes Delta is a major restoration opportunity. The mouth of the Deschutes River was converted into a reflecting pool for the state captial, but over time has accumulated sediment, surplus nutrients and an infestation of New Zealand mud snail.
  • There are 11 Budd Inlet MTCA Sites located in at the southern head of Budd Inlet identified as part of the Puget Sound Initiative.
