July is the last opportunity to schedule a bat activity survey! Bats are active, feeding and using numerous roosts, with pregnant females settled in their maternity roosts. It is essential to survey trees or buildings with known roosts or high roost potential before any works are undertaken, in order to minimise the risk of disturbance or loss of bat roosts. Our initial bat assessment can inform whether or not an activity survey (emergence or pre-dawn) is required. Activity surveys need to span the maternity roost period, so the first visit should be pencilled in during July/early August latest.
EECOS can carry out bat surveys and recommend appropriate mitigation and work methods to minimise the impact on bats and roosts prior to any works. Our surveys involve using detectors during dusk and dawn, and monitoring emergence/re-entry of bats at roosts.
Our initial Phase 1 surveys (PEA) flag up any surveys that may be needed for these and other protected species so that these can be scheduled in good time. PEAs can be carried out now and through the year.
Contact EECOS if you need a quote for any of the above surveys and services.
Essex Ecology Services Ltd (EECOS) is currently working on:
• BREEAM and Code for Sustainable Homes surveys for three sites in London: a hotel, primary school and medical centre;
• Invertebrate survey at Layer Breton Heath to guide management;
• Water Vole survey at The Lake, Canvey Island;
• Ecological assessments of various Anglian Water schemes, including proposed new pipelines and installation of new facilities at treatment works;
• Surveys of bat activity at Abberton reservoir for Essex & Suffolk Water have recorded Common, Soprano and Nathusius’ pipistrelle, Noctule, Serotine and Myotis species;
• Botanical surveys of grassland sites across Essex;
• Great Crested Newt licensed mitigation at a site near Colchester and Felsted;
• Environmental Statement (ecology section) and various protected species surveys for a site near Braintree;
• a range of mitigation work protecting Great Crested Newts, bats, reptiles and `Important` hedgerows along a pipeline route in Suffolk;
• Bat survey of Colchester cemetery for the local council;
• On-going management of landscaping work on an Essex trunk road;
• Invertebrate survey of coastal grassland at Shoeburyness (planning matter);
• After a successful Great Crested Newt licence application, EECOS has been heavily involved in newt translocation and habitat enhancement for a small development plot near Great Dunmow;
• Bat surveys and ongoing mitigation advice for Anglian Water at two sites involving roosts of Common Pipistrelle and Brown Long-eared bats. Works on the former roost was postponed until after the winter period in order to avoid any risk of disturbing bats in hibernation; summer activity surveys will determine whether or not a Natural England licence is needed for works within the Brown Long-eared roost .
