Geothermal Invasive, Nonnative Species

Invasive, Nonnative Species
Present, Potentially Affected

Invasive species reproduce quickly to become widespread and cause harm to other species. They are a threat because they interrupt the food chain by consuming and competing for native species, resulting in a shorter life span for native species. Invasive species also carry disease. This threatens biodiversity and changes the ecosystem’s survival mechanisms. Invasive species are mobilized via wood byproducts, boats, cars, people and pet purchasing. Non-native species include fish, fungus, bacteria, plants, mammals and insects.

Non-native species reside in environments made for species with a different set of adaptations than the ones they have. This makes them potentially harmful to the environment as they may carry disease. These species are undesirable because they usually require specialized care to stay healthy by increasing competition and decreasing biodiversity. Specialized characteristics include a larger water supply, a specialized diet unfit for the area, are toxic to other species and require a warmer or cooler climate.

The Bureau of Land Management (BLM) requires a management plan to mitigate not only the widespread of invasive and non-native species, but also the toxicity to humans and native species. Weed management must continue three years after the pumping cycles are complete. National Wildlife Federation-Invasive Species

Invasive, Nonnative Species Impacts & Mitigation

Invasive and Non-native Species can cause adverse impact affects. The following indicates impacts and mitigation measures:

Impacts

  • The widespread germination of noxious weeds.
  • Harmful fungus and bacteria build-up on construction and personal vehicles; and building material.
  • Slim competition elsewhere increases invasive and non-native biodiversity growth to alter the natural environment.

Mitigation:

  • Evaluate the site for any invasive and non-native species, e.g. weeds. Map affected areas.
  • Power-wash all vehicles entering the site to remove soil and plant particles. Contaminated residue will be disposed off-site.
  • All employee clothes and shoes will be inspected and treated accordingly for contaminants.
  • Use weed-free soil and seed mix for revegetation.
  • If herbicides are permitted, consult the BLM for application processes
  • Protective equipment is required when applying herbicides.
  • Avoid herbicide applications during flowering season when pollination occurs to eliminate additional herbicide treatment.
  • If herbicides are not permitted, remove plants by hand.
