The Scotch Broom is over growing native species and because it is a heavy pollinator it is creating allergry and respiratory problems.

Unfortunately, the pine beetle is starting to gain ground on the Alberta side of the Rockies. A string of warm winters has not helped. I was just in Banff at the end of February and I remember wondering to myself if the scenery would be quite different in one or two years if the pine beetle causes the kind of devastation that it has elsewhere.
More locally, our poor linden tree has a gall mite infestation. Last spring and summer, we had a company come to spray safer soap on it and that seems to have made a difference, though it may take three seasons to clear. It's a beautiful tree, so I hope it survives.
Speaking of infiltrating pests, who can forget the phylloxera infestation that wiped out the vineyards of Europe in the 19th century? If not for the discovery of grafting vinifera vines onto American root stock, we would be drinking Bordeaux wines made from Catawba and Concord. And it's not all ancient history. The threat of another phylloxera outbreak is an ever-present worry for California wineries. Even Chile, which has been geographically isolated from phylloxera all these years, cannot let their guard down.
What a thought! Better have a glass of wine.
Cheers!

every state has a noxious weed list. This is a list of plants that cannot be planted inside a state due to this problem. Scotch broom is on Idaho's list - this i know because it was on a weed test in my agricultural chemicals class this morning. According to our books and state website the only way to effect the scotch broom is herbicide applied to young plants.

Be careful here. Ask the Hawaiians about how they controlled the sugar cane rat population by importing the mongoos from India. Backfired big time.

Doesn't everyone? Japanese beetles are old standbys. Snakefish are lurking around the ponds in the east part of Maryland, and if we got lots of global warming, the kudzu, which is well into Virginia, may make it into our forests.
