Ecological Surveys

Full Ecological Impact Assessments (EcIA) for Large Developments

An Ecology survey is a detailed report on the likely impact that a proposed development will have on wildlife. It is usually required by the planning authority as part of a planning application.
For small developments, a ‘walk over’ survey is carried out. This involves a site visit to record habitats at phase 1 level and assess the site for protected species. The report will also include the results of a desk study. This is a basic survey intended for small scale developments such as a single wind turbine or residential property.
A larger development may also require a full Ecological Impact Assessment (EcIA), which is an extension of the ecology walk over survey and includes any dedicated protected species surveys together with agreed mitigation procedures.

The team at Biodiversity Solutions can deliver a comprehensive Ecological survey report to a high standard which will identify any ecological constraints and suggest realistic and cost-effective mitigation, where necessary. We work closely with our clients and have experience in a wide range of developments, including Wind Farms, road building schemes, property enhancements and developments.

Timing of surveys

It is very useful to carry out an initial scoping survey at an early stage to identify any likely ecological constraints and species needing detailed survey or NRW license applications. The species surveys often have to be done at a specific time of year, so starting early can avoid long and perhaps costly delays.

The following box highlights some of the timescales we work to throughout the year for a range of species.

Dormice nest tube survey    April to October (site tubes in April)
 Dormice nut search   September and October
 Breeding birds    April to June
 Wintering birds   November to February
 Reptiles   March to September
 Phase 1 and other vegetation   Best in April to September
 Badger     Possible any time but best in winter
 Bat activity surveys  May to September
