Ecology Survey Bristol: Ecological Survey and Assessment

What is an Ecological Survey?



Ecological surveys are used on proposed development sites to establish any environmental impacts which the potential development may cause. Ecological surveys may be required during the planning process to ensure planning applications for development and construction are successful. The local planning authority will use the survey to consider how the development will positively or negatively impact the environment of the area.

An ecological site survey will access all areas of the development site and will highlight anything that could cause concern from an ecological standpoint. A survey will also identify any protected species and habitats that are within proximity of the site.



Ecology Survey Bristol: Survey Stages

Preliminary ecological appraisal (PEA) :This is the first survey carried out by a licensed ecologist, known as a phase 1 habitat survey. It is an initial desktop study and a walkover survey. A PEA survey will identify the various habitats and species that are present within the site. It will also highlight any planning policy issues and potential impacts of the development on a particular species. 

Ecological impact assessment: This is an essential document that describes the potential effects of any activities on the environment. This assessment takes the results that have been provided from the PEA and uses them to assess the impact by undertaking detailed habitat specific surveys.

Protected Species Survey: If there is any indication that a protected species could be present on a development site, a protected species survey will be required. Common types of protected species surveys include badgers, great crested newts, bats, barn owls, water voles, and nesting birds.  badgers, great crested newts, bats, barn owls, water voles,  nesting birds, and invertebrate surveys.
