Invasive species spread from manmade settings (gardens, agricultural areas, etc.) into the wild. Once in the wild, invasive species can reproduce virtually unchecked and displace native species, which can result in forest ecosystems that lack plant diversity. Native wildlife also suffers due to lack of preferred plants for food and shelter. Our natural ecosystems are very complex. Native species of plants have well-established relationships with other native species, as well as native wildlife, that have evolved over time. These relationships ensure that native plant populations are kept in balance with the rest of the natural world. Invasive species, on the other hand, do not have any natural herbivores, parasites or diseases to keep them in check in our natural areas. Because of this, invasive species reproduce rapidly, displacing native plants and negatively affecting the many wildlife populations that depend on the native plants for food and shelter. In worst-case scenarios, invasive species disrupt the function of the entire ecosystem and change the character of the region by altering important processes like fire, nutrient flow and stormwater management. There are many tools to consider when trying to manage the problem of invasive species. The best way to start is to avoid planting the invasive species at all. Before changing the landscaping in your yard or common areas shared with neighbors, please make sure to select plants that are not on the City’s invasive plant list. You can also explore additional resources to identify plants that are known invasive species in this area. The City is trying to manage invasive species that have already escaped into the wild. We are in the beginning stages of developing an invasive plant management plan for our park system. |
