About us

Some plants, introduced by humans outside their native range can grow faster than native species and may have no natural predators so can spread quickly These plants are invasive non-native species. They can compete with and displace native species, spread disease, alter local ecology, lessen biodiversity and clog waterways. This adversely impacts recreation by affecting water quality, fishing and navigation.

We need your help

In order to effectively combat invasive species, we first need to know where they are. Once you know this we can coordinate treatment and target priority areas. You can help by reporting any invasive species that you see by recording them through this website.
