AMENDATORY SECTION(Amending WSR 92-07-024, filed 3/10/92, effective 4/10/92)
WAC 16-752-500 Establishing wetland and aquatic weed quarantine. Washington waters and wetlands are threatened by nonnative, aggressive((
, perennial)) weeds that destroy the
commercial, aesthetic, fish and/or wildlife habitat, and
recreational value of these areas. (( Parrot's Feather (or
parrotfeather or waterfeather))) African elodea, Brazilian elodea
(or egeria), Eurasian watermilfoil, (( and)) 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 species, when established, form
dense mats that will clog irrigation systems and waterways,
displace native species, alter fish and wildlife habitat, and
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 cordgrass, common cordgrass, and smooth
cordgrass are noxious weeds that have invaded ((
a small part of
the)) salt water estuarine areas on the Washington coast
displacing native species, 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.
