Seaham Sewage Treatment Works Nature Reserve: scrub management and invertebrate banks

Seaham Sewage Treatment Works Nature Reserve: scrub management and invertebrate banks

Volunteers visited Seaham Sewage Treatment Works Nature Reserve for the first time, to clear scrub and create invertebrate banks.

It is most of the volunteers first time at Seaham, so after they eventually found the site we spent the day clearing scrub from around the pond. Scrub and trees developing on the pond margin can trap silt; encourage plants to grow which can take water out of the pond. The trees we removed were alder, which can grow quickly and increase the drying out process. Removal of these trees will also allow the marginal pond plant community to develop.

We also dug out an experimental invertebrate bank. The grassland around the pond and adjacent treatment works is species rich with an array of flowering plants and is an excellent pollinator resource. The volunteers opened up a bankside by removing vegetation to form bare ground for burrowing invertebrates. We will be back next year to review during our creeping thistle management.
