Ecology Survey Holywell: Surveys and Assessments

What is an Ecology Survey?

Ecological surveys are undertaken on proposed development sites to establish any environmental impacts which the development may cause. Ecological surveys may be required during the planning process to ensure planning permission 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 highlight anything that could cause concern from an ecological standpoint. A survey will also identify any protected species and habitats that are present within proximity of the site. 


Ecology Survey Holywell: Types of Survey

Preliminary ecological appraisal (PEA) – This is the first survey that is carried out by licensed ecology consultants. Otherwise known as a phase 1 habitat survey, it is an initial early stage 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 ecological assessment takes the results that have been provided from the PEA and uses them to assess the impact by undertaking detailed habitat-specific surveys such as bat 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, barn owls, water voles, nesting birds, roosting bats and great crested newts. Please be aware that the optimal time of the year to complete these surveys is during the summer months.

Full members of the chartered institute of ecology and environmental management (CIEEM) can provide further information on these surveys.
