MAP OF THE ESTABLISHED POPULATION OF AMUR CORK TREE IN DUNN COUNTY

Last fall LCIP members have found and identified female and male Amur Cork Trees in Dunn County. So far we have found 15 locations with probably many more to be found. If you do see this plant send us some photos of the inner neon yellow bark and whole tree to verify its location. We will then do a follow up visit to confirm and survey the population size. Check out the photos below to see what this WDNR prohibited tree looks like!
Invasive species in West Central Wisconsin
So far we have found 39 invasive species in our region. There are probably more that we haven’t found yet, but we will keep looking and reporting back to you! Thanks.
NR 40 Revision Information
The Department of Natural Resources revised Wisconsin’s Invasive Species Rule (ch. NR 40, Wis. Adm. Code). The changes include delisting 2 species, changing the regulated status of 4 species, listing 51 new prohibited species, listing 32 new restricted species, and listing 2 species as split-listed (prohibited/restricted). . Here is the printable 2015 NR

This curve shows how as time increases, the amount of area that is infested and the cost to control the invasive species increases exponentially.

General Information About Invasive Plants
“Invasive plants are plants which grow quickly and aggressively, spreading and displacing other plants. Invasive plants are usually introduced by people either accidentally or on purpose, into a region far from their native habitat. Invasive plants are often referred to as “exotic,” “alien,” introduced” or “non-native” species. In their natural range, these species are limited by environmental, pest or disease conditions, keeping these species in balance within their ecosystem. When introduced into an area where these limitations are absent, some species have the ability to become invasive. These are the species we are concerned about in conservation.
Recognition of the problem of invasive plants is growing, at the same time as damage to native ecosystems is mounting. Identifying invasive plants and understanding the potential damage they can cause is essential to stopping their spread and protecting native vegetation.” -PA DNR
Invasive plants:
- Produce large numbers of new plants each season.
- Tolerate many soil types and weather conditions.
- Spread easily and efficiently, usually by wind, water, or animals.
- Grow rapidly, allowing them to displace slower growing plants.
- Spread rampantly when they are free of the natural checks and balances found in their native range.
