Stop the spread
Can you help us map non-native invasive plants across the River Thame catchment.
Non-native invasive plants out compete our native plants and, if left to their own devices, can take over whole river banks, streams and ponds. Without effective control methods they can quickly spread and recolonise areas after removal.
We need your eyes to help us map the locations of these non-native plants. This way we can effectively target areas to ensure they are removed for good.
If you are interested in surveying for non-native invasive species please email Hannah at email@example.com

Non-native plant species
Below are identification sheets for a selection of non-native invasive species that we are trying to map the locations of. These Identification sheets were produced by NNSS. For more information on non-native species and national projects to tackle them please visit the NNSS website.
