Below are some recent case studies of work that has been undertaken by Sussex Ecology.

An example of a successful reptile mitigation project (2011)

WHY SURVEY WAS UNDERTAKEN
Sussex Ecology was commissioned to undertake ecological surveys on a proposed development site. A Phase I survey in early April indicated that the site had a high potential for reptiles and great crested newt. In addition, the need for bat surveys was required following an initial building inspection.

SURVEY METHODS
Standard survey guidelines were followed including visual search and artificial refugia survey for reptiles, torching, bottle trapping and egg search for great crested newts and dusk emergence surveys for bats. The surveys were undertaken in optimal weather conditions between April and June 2011 by 3 consultants.

RESULTS
Surveys revealed that a low population of grass snake was present on the site. An unconfirmed female great crested newt was reported approximately 500 m from the development. No significant bat roosts were found within the existing building.  

OUTCOME OF THE SURVEYS AND MITIGATION
The surveys revealed that protected species were present (grass snake). An appropriate mitigation strategy was put in place and a suitable receptor site selected adjacent to the site. Reptiles were also excluded by installing reptile fencing around the boundary of the site to prevent re-entry of reptiles to the site. The grass snake population was moved successfully before clearance work commenced.

Reasonable measures were put in place to prevent great crested newts from being harmed during operations as well as additional terrestrial searches. Bat boxes were installed around the site prior to demolition of the building, and one of our consultants carried out a “watching brief” during the demolition work. 

The Reptile Receptor Site, where the reptiles were moved, will be managed in a sympathetic manner and enhanced for it’s reptile interest for the next 5 years. The project has ensured that there will be no net loss of local reptile conservation status. In addition, post-development monitoring will be undertaken by our team to ensure that the grass snake population is thriving in their new home.

Many thanks to all of those involved with this exciting project, including our ecological contractors.
