;Invasive species

;Invasive plants

:Typically non-native plants that out-compete native species. These species lack natural predators, grow aggressively and reproduce rapidly and can be problematic in the natural environment.

:Shredded woody material or leaf compost used as a top dressing over vegetation beds that provides a source of soil nutrients and helps retain soil moisture; in bioretention cells and dry swales the surface mulch layer provides pollutant removal and improves growing conditions for the selected plants; shredded hardwood bark has been found to work best as it is less likely to float.

:Defined as those plants (including grasses, herbaceous species, shrubs, vines and trees) that have historically existed within a particular area.  Native plants have co-evolved with the local ecosystems and natural processes.
