Spartina (densiflora; alterniflora; anglica; patens)
Each year, federal, state, local governments and private landholders spend thousands of dollars trying to control the infestation of non-native Spartina in the waters of the State of Washington. First introduced more than 100 years ago to the tidelands of Willapa Bay it rapidly expanded to over 8,500 choked acres by 2003. Prolific seeds and disturbed clumps of clones eventually made it out of the Bay and drifted along the Coast, entering Grays Harbor and establishing colonies in the interior of the Harbor by 1990. |
