Terrestrial Invasive Plants

A terrestrial plant is literally defined as 'a plant that grows on land'. Here we are referring to non-native plants that grow in a variety of habitats that are not aquatic or on rangeland, including roadsides, right-of-ways, forested habitat, or in backyards. These plants cause a variety of negative impacts, such as preventing the growth of native plants, reducing sightlines along roadways, road bank erosion, outcompeting seedlings planted during reforestation efforts, creating barriers for recreational access, and reducing aesthetic appeal. Some terrestrial invasive plants cause social impacts such as pollen production that increases allergens in the air, or in the case of scotch broom, which produces a large amount of dry biomass as it dies back, increases the likelihood and intensity of wild fires.
