What do you do with your weeds?
Many people are concerned about “invasive plants.” These are weeds that spread abundantly into wild vegetation and displace more valued native species. Sometimes there are good conservation reasons to reduce the abundance of environmental weeds.
Abundant large weeds, such as water-chestnut, purple loosestrife, common reed, and Japanese knotweed, need to be managed in some places to reduce harm to native species of plants and animals, yet all are used by many native and nonnative organisms and have potential for medicine and bioenergy.

Herbicides and biological control present many risks. Mowing, livestock grazing, burning, temporary flooding, and other techniques are safer and effective in appropriate settings.
