Where do weeds thrive?
Weeds typically become established in highly disturbed sites
such as river and stream banks, trailheads, roadsides, building sites,
trails, wildlife bedding grounds, overgrazed areas, and campgrounds. Consequently,
well-managed land is the best defense against the spread of invasive weeds.
However, even well managed land in good condition is susceptible to invasion
when natural disturbances (such as wind, water, fire, and a wide variety
of wildlife, including birds and mammals) open niches in the plant community
and distribute plant parts and seeds. Once established, weeds can be spread
by many vectors, including vehicles, wind, recreationists, waterways,
animals, and weed-contaminated hay. |
