City of Port Washington - Tips For Going Green

Invasive Species

According to the National Invasive Species Information Center, invasive species are plants, animals or pathogens that are non-native (or alien) to the ecosystem under consideration and whose introduction causes or is likely to cause harm. What does that mean for Port Washington? Port Washington, like many other communities, need to look out for invasive species and to save its natural areas from them.

In Port Washington, purple loosestrife and reed canary grass have been identified as significant invasive plant species present in the City, along with garlic mustard, leafy spurge and buckthorn. These invasive species, along with other invasive species, are so successful because they don't have their normal predators and competitors keeping them in check like they would in their typical habitat. This is one of the reasons today that many species are on the endangered list - they can't compete with the invasive species.

Not only are invasive species bad for natural habitats but are also very costly, and can be dangerous. The U.S. spends billions of dollars a year from damages associated with invasive species and controlling them. Many industries are also negatively affected by invasive species. Certain invasive species, like wild parsnip, are dangerous to human health. When touched, wild parsnip causes burns and blisters to bare skin.

Ozaukee County and the Ozaukee Washington Land Trust are both trying to manage invasive species. The Land Trust says that 80% of their management and protecting efforts at their stewardship sites is dealing with invasive species. The main invasives the Land Trust deals with are garlic mustard and invasive trees and shrubs like buckthorn. What is shocking is that out of their 22 plus preserves not one is invasive free. The Land Trust also says that the areas that have the least invasive species require the most work and even with all of the work they put in it still gets worse every year. The Land Trust deals with Invasive species by manually pulling the plants along with applications of herbicide.
