They’re especially common in urban and brown-field habitats, and love railway embankments and the damp soils of water ways. One of the most difficult aspects of controlling them is […] Read more

Many times, the reason a plant or animal is causing problems within an ecosystem is because it doesn’t belong in that system. It hasn’t evolved in equilibrium with the other species there, and thus out-competes them. […] Read more
