We are well placed to carry out all types of ecological surveys across Bristol surrounding areas such as Long Ashton, Pill, Portbury, Filton and Warmley. The standard Phase 1 habitat survey methodology whereby colour coded habitat maps are drawn up showing the extent and distribution of the different habitat types present on a site.

The Phase 1 survey identifies habitats and features on the site that may constrain development and evaluates the potential of these habitats to support protected species. If the site is assessed as having low wildlife interest, then no further surveys may be needed. If necessary, clients are advised to undertake more detailed specialist studies of the site.

A data trawl is usually undertaken in conjunction with the survey, whereby information about the site and its context are obtained from organisations such as Local Biodiversity Records Centres. This includes information on protected and Biodiversity Action Plan priority species and the presence of nearby statutory protected areas.
