Are invasive species killing us? This question must sound a little over the top if you think that invasive species are just garden pests, but history is filled with examples where they've killed humans.
Nearly every day, we read about problems caused by invaders like the emerald ash borer killing trees across New York, West Nile virus killing people across the United State (1,499 so far), zebra mussels clogging water intakes and changing the Great Lakes and Hudson River ecosystems and Burmese pythons eating everything in the Everglades.
A short documentary by the American Museum of Natural History. The video highlights zebra mussels in the Hudson River and the Cary research that closely analyzed the river before, during and after the invasion.
Humans have carelessly moved thousands of species outside their native ranges through activities such as transfer of ballast water, release of pets and bait, movement of untreated wood, escapes from agriculture and aquaculture, and deliberate release of species that we thought to be beneficial.
Private hunting preserves in New York release wild boars for "trophy hunters" to shoot. This benefits only a tiny population of hunters and the game preserves, while presenting serious risks to the public.
One of the best-known bits of folk wisdom about invasive species is that they settle down after a while to become part of a rebalanced ecosystem, and stop being a problem. This is an appealing idea, but how often is it true?
When people think about climate change, the first thing that usually comes to mind is blazing hot summer days, severe droughts, or super-size hurricanes. But climate change is actually more significant in winter than in summer.
Last month's news that the invasive silver carp had crossed the electric barrier in a canal in Chicago ― and were only a short day's swim from invading Lake Michigan ― caused outcries from the outdoor community and tourist industry across the Great Lakes region.
New York state is taking an essential step to deal with invasive species, one of the most damaging and difficult environmental problems of our time, by proposing to limit the importation of ballast water into the state.
My backyard is being devoured by a silent but aggressive invader, multiflora rose (Rosa multiflora). This thorny perennial shrub is an Asian import with arching green stems called canes that can reach 10-15 feet long.
If you’ve walked much along the Hudson’s shores, you’ve probably seen thorny, black water-chestnut seedpods piled up along the high-tide line, thick stands of common reed in wetlands and along the railroad tracks, mute swans gliding across the water, carp splashing in the shallows, chunky shells of Atlantic rangia on the beaches of Haverstraw Bay, and the thin, sharp shells of zebra mussels littering shorelines from Newburgh north.
