• Habitat destruction is the most widespread threat to mammals, affecting 37% of all extant and recently extinct species, followed by overexploitation (17%), invasive species (6%), pollution (4%), and diseases (2%).

• However, subtle assaults to endangered species may include the use of fertilizers, herbicides, and insecticides that may reduce plant pollinators, invasive plant species that may out-compete the endangered plants, and introduced foreign diseases, insects, or domesticated/feral animals that may further endanger plants.

• For terrestrial species, habitat corridors promote the movement of species (Gilbert-Norton and others 2010), although they can potentially facilitate undesirable outcomes such as spreading disease and invasive species (Heller and Zavaleta 2009).

• Increasing ecological resistance to invasives is facilitated by early detection and long-term control efforts, both of which require ongoing funding (Myers and others 2000).

• By creating niche gaps that can act as gateways for invasives, erosion directly affects weed populations

• These guidelines encourage landowners to keep natural, mature woodland sites wooded while allowing for the restoration of former savannah and grassland habitats that have been invaded by small juniper (or other invasives).
