Scotch broom crowds out native species and negatively impacts wildlife habitat. It can form dense, impenetrable stands that degrade farmland, prevent or slow forest regeneration and restoration of upland sites and wetland buffers, and create fire hazards. Scotch broom produces toxic compounds, which in large amounts can cause mild poisoning in animals such as horses.Mulched at the right time of year (before seeding) and overseeded, you can fight a fair battle with this plant.

 

Himalayan blackberry shades out smaller, native species, reducing native plant and wildlife diversity. Its extensive stands can decrease usable pasture, limit animals’ access to water, and trap young livestock. Blackberry fruit can be a food source to invasive birds and mammals such as European starlings and rats.
