2 WRIA 16 – State of the <strong>Watershed</strong><br />
Roads and highways are just<br />
one of the factors that have<br />
impaired WRIA 16’s salmon<br />
habitat. This photo shows an<br />
early highway (perhaps an<br />
early Highway 101) along<br />
Hood Canal. Photo courtesy<br />

Department of Transportation<br />
Development and human<br />
activity have altered<br />
WRIA 16’s fish and<br />
wildlife habitat in several<br />
ways<br />
Finally, the impacts of invasive species and abandoned fishing gear and<br />
boats can alter habitat for fish and other wildlife. Invasive species are<br />
plants, animals, or other organisms that are non-native to an area and<br />
whose introduction causes economic, environmental, or human harm.<br />
Some invasive species (such as knotweed) can directly affect fish habitat by<br />
invading streams. A particular local focus is on invasive species that have<br />
been designated as noxious weeds (such as knotweed, tansy ragwort, and<br />
many others). <strong>Mason</strong> and Jefferson counties both maintain Noxious Weed<br />
Control Boards to assist landowners with weed identification and control.<br />
Invasive marine animals can also cause problems. For example, a highly<br />
invasive species of tunicate (sea squirt) has recently been found in Puget<br />
Sound. This tunicate grows in large colonies, spreads across shellfish beds,<br />
and chokes off the habitat and food supplies of fish and shellfish.<br />
Derelict (abandoned) fishing gear and boats affect wildlife and people. Lost<br />
or abandoned nets, lines, traps, boats, unused dock pilings, anchors, floats,<br />
and other equipment can: (1) trap and wound fish, shellfish, seabirds, and<br />
marine mammals; (2) entangle swimmers or divers; (3) damage recreational<br />
boats or commercial vessels; (4) degrade marine eelgrass beds or other<br />
important habitats; and (5) create unpleasant sights.<br />
To address the factors and impacts discussed above, several efforts are<br />
underway in WRIA 16 to plan for salmon recovery and implement habitat<br />
restoration activities. For example, the Hood Canal Coordinating Council<br />
(HCCC) is the Lead Entity for salmon recovery in the Hood Canal region<br />
and has drafted a Salmon Habitat Recovery Strategy to guide recovery efforts in<br />
the region (HCCC, 2004). The HCCC has also drafted a Summer Chum<br />
Recovery <strong>Plan</strong> (HCCC, 2005) which includes several recommended recovery<br />
actions. In addition, Shared Strategy is a collaborative Puget Sound-wide<br />
effort to engage local citizens, governments, tribes, technical experts and<br />
policymakers to take action to protect and restore salmon runs in the Puget<br />
Sound region. The efforts of Shared Strategy in Hood Canal are focused<br />
primarily on assisting with the recovery of threatened summer chum in<br />
Hood Canal (Shared Strategy, 2005a).<br />
SUMMARY AND KEY ISSUES: HABITAT<br />
Based on review of the existing habitat assessments conducted in WRIA 16,<br />
the <strong>Plan</strong>ning Unit has identified the following key issues to be addressed by<br />
this watershed plan. Note that elevated stream temperatures are an<br />
additional issue that affects habitat; this issue is discussed in the Water<br />
Quality section, which begins on page 20.<br />
• Floodplain connectivity, channel complexity, and riparian<br />
conditions have all been degraded by development. In<br />
particular, diking, bank armoring, and highway construction have<br />
removed streamside habitat and blocked access to side channels.<br />
Riparian areas have been developed for residential or agricultural use,<br />
thereby removing vegetation that helped control runoff and<br />
