B3. - Invasive Trees.  


Latest version.
  • Similar to the non-native trees listed in Table 2, invasive (or "exotic") trees can out-compete and gradually displace native plants, resulting in a loss of wildlife species that depend upon them. Invasive trees however, pose a greater threat because they can rapidly spread and suppress growth of surrounding plants by shading them out, chemically poisoning them, or out-competing them for food and water. The planting of invasive trees is prohibited in the coastal zone.
