Plymouth Ancient Tree Survey

Plymouth City Council

This work involved the following:

An initial desk study mapping existing records of ancient, veteran and notable trees in Plymouth on GIS using information from previous surveys and from the Council Tree Officer.

  • Site visits to record and photograph trees using Woodland Trust methodology.

Production of a final GIS layer of the trees incorporating additional GIS data from the National Trust.

Liaising with the Woodland Trust to ensure data gathered was incorporated into their national ancient tree hunt survey.

County Wildlife Sites

Also Known as Local Wildlife Sites

There are approximately 2,200 County Wildlife Sites (CWS) across Devon comprising a range of habitats and species.  Unlike Sites of Special Scientific Interest (SSSI), CWS are not legally protected but comprise a network of non-statutory wildlife sites. Some CWS, however, can be of similar ecological quality to SSSIs.

Biodiversity Monitoring Framework

Principle funders: Devon Wildlife Trust and Devon County Council

The Biodiversity Monitoring Framework (BMF) is one of the largest habitat monitoring projects in the UK.  It is a complex project with an overall aim of finding out how the wildlife of Devon is faring. The main part of the project involves surveying a number of existing County Wildlife Sites (CWS) following a specific methodology each year.  The information gathered helps to monitor the quality of individual CWS over time but to also determine patterns of change in habitats across the county as a whole. 

This project has been running since 2009 and during the first five years, approximately 500 CWS were surveyed as a part of the BMF project. Many of these sites had not been surveyed since the early 1990s.  DBRC carry out the majority of the surveys but a number have been carried out by partner organisations such as Devon Wildlife Trust’s Working Wetlands team and Dartmoor National Park Authority.

Following the survey, landowners are given a report for their CWS providing detailed information on the habitats present and recommended management advice tailored specifically to their site.  We can also forward landowners to sources of further advice and/or funding.

All of the information gathered is fed into annual reports, compiled by Devon County Council, which review trends in Devon’s natural environment.
