Roger Woodruff, state director of wildlife services for the USDA in Olympia, said there's a window of three to four weeks in June and July when geese molt and can't fly.
So on June 28, Woodruff's
agency herded the Puyallup geese to a pen at Bradley Lake Park and gassed them with carbon dioxide -- the most humane way to kill them, he
The agency does so at the request of communities where geese are causing problems, Woodruff
"It's been a difficult issue to deal with," he
The animals were imported to Washington in the late 1960s and early 1970s in an effort to replace native geese whose nests were flooded by dam projects on the Columbia River.
In 2000, there were about 25,000 of them in Western Washington, causing about $1 million in damage annually, Woodruff
That year, the agency opted for the last resort: catching and killing them.
"Boy, that has really, really turned things around," Woodruff
