Invasive Species Advice and Control

Invasive species are those that have been introduced to an area outside their natural range. As the population grows in its new habitat, it can cause a multitude of problems, such as ecological, economic and public health concerns. Invasive species may belong to any taxonomic group (mammals, reptiles, birds, amphibians, plants, invertebrates, fish, viruses).

Some cases have documented such populations growing beyond control, with the invader rapidly colonising the new habitat. Across the world, a variety of techniques have been applied to try and control the spread of such species, including preventative, chemical, biological and legislative methods. The best method being preventing the establishment of such species, aided by early monitoring and a rapid response. If such species are detected prior to becoming established, the removal process is simplified. Conversely, once such species are established in a new habitat, eradication becomes far more difficult.

In the UK invasive species include Japanese knotweed Fallopia japonica, Himalayan balsam Impatiens glandulifera, water fern Azolla filiculoides, Zebra Mussel Dreissens polymorpha, Harlequin ladybird Harmonia axyridis, grey squirrel Sciurus carolinensis, amongst others.

The OpenSpace team can give advise on invasive species and their control, with previous experience controlling such species found on a range of sites. If you have an invasive species, then do call us on 01228 711841 or email us at enquiries@openspacegb.com.
