We’ve been in the field carrying out invertebrate surveys this week
Mike and Bea have been out in the field this week, completing aquatic and terrestrial invertebrate surveys on behalf of The Landmark Practice at a site in North Somerset.
Part of the site has been managed with conservation in mind with efforts made to improve the habitats in the fields, ditches and ponds found on the site. Monitoring of the invertebrate fauna has been completed since 2008 to assess the impacts of revised management planning at the site.
Aquatic invertebrate samples were taken from ditches and ponds around the site with a number of water beetles, dragonfly and damselfly larvae spotted in the samples. An adult Hairy Dragonfly was also seen flying low over one of the ditches.
Sweep samples and direct searches of plants and hedges proved fruitful for terrestrial invertebrates and initial identification has already turned up the RDB3 beetle species Cantharis fusca and a notable soldierfly species, the Ornate Brigadier Odontomyia ornate.Staff were also treated to views of a Barn Owl hunting low over the fields, carrying prey back to its nest box.
All of the samples will be analysed in our laboratory here at Slimbridge with the results feeding into future management planning of the site. A second visit is planned for later in the summer.
