AMENDATORY SECTION(Amending WSR 01-01-014, filed 12/6/00,
effective 1/6/01)
WAC 16-752-500
Establishing wetland and aquatic weed
quarantine.
Washington waters and wetlands are threatened by
nonnative, aggressive weeds that destroy the commercial,
aesthetic, fish and/or wildlife habitat, and recreational
value of these areas. ((African elodea, Brazilian elodea (or
egeria), Eurasian watermilfoil, fanwort, slender-leaved naiad,
hydrilla and water chestnut (a different species from the food
"water chestnut" commonly sold in grocery stores) are
submersed, rooted species that can invade shallow to deep
water. Parrotfeather, water primrose, and yellow floating
heart are rooted plants that invade shallow water and aquatic
margins. European frogbit and swollen bladderwort are freely
floating species.)) These rooted or freely floating plant
species, when established, form dense stands or mats that
((will)) clog irrigation systems and waterways, displace
native species, alter fish and wildlife habitat, and/or
seriously impact recreational use of the waterways.
((Garden loosestrife, hairy willow herb, grass-leaved
arrowhead, mud mat, marsh dew flower and flowering rush are
rooted plants which invade wetlands, shallow water and aquatic
margins. When established, their dense stands displace native
vegetation and harm wildlife habitat.
Salt meadow)) Several species of Spartina, generally
known as cordgrasses, ((common cordgrass, and smooth cordgrass
are noxious)) are nonnative, highly aggressive weeds that have
invaded salt water estuarine areas on the Washington coast,
displacing native species((,)) and threatening bird and mammal
habitats and the shellfish industry. ((Dense-flowered
cordgrass, a closely related species, has potential to
duplicate this invasion.))
The director of agriculture, pursuant to the powers provided in chapters 17.10, 15.13 and 17.24 RCW, finds that the regulation and exclusion of these plants and plant parts are necessary to preserve Washington waters and wetlands, both fresh water and estuarine, from new or additional infestation. These requirements and restrictions, contained in WAC 16-752-500 through 16-752-525, are in addition to the requirements contained in WAC 232-12-271, "Criteria for planting aquatic plants and releasing wildlife," administered by the Washington state department of fish and wildlife.
