I read Catherine Minolli's column 'Mother Nature's wisdom in threes' regarding trillium flowers in last week's Tri-City Times.
We have white trilliums at the back of our 10 acres. They used to be more plentiful than now but I cannot say if it is the woodchucks or deer that are causing the serious decline in numbers. Rather it is a problem that includes increased building and lack of appropriate planning for storm water runoff creating periodic flood conditions which wash these delicate flowers away. It seems that, perhaps out of convenience, storm water runoff is directed toward "unused" wooded areas instead of planning with retention or detention ponds.
