Salix Ecology

Salix Ecology is an ecological consultancy covering London and the south-east. We specialise in surveys and training for ecologists. We are known for providing an impartial, objective and cost effective service for all our clients.


We have a proven and unparalleled track record in delivering high quality and accurate habitat surveys. These are underpinned by our botanical and mapping expertise. We use the latest technology, including sub-metre accurate GPS systems and drones to produce accurate habitat maps.

Good quality habitat surveys will be essential for calculating 'Biodiversity Net Gain', which will become a legal requirement for all new developments when the Environment Bill 2020 is adopted.

We carry out Preliminary Ecological Appraisals, Phase One Surveys, UK Habitat Classification surveys, National Vegetation Classification (NVC or Phase 2) surveys and habitat monitoring. We have experience in complex, large scale surveys as well as surveys for smaller scale developments.

See our ecological survey page for more details

Drone mapping and aerial photography

We often use drones to produce highly accurate habitat maps.
By flying over a site at a set altitude we take a series of overlapping images to create an orthomosaic photo. This is a series of individual photos which are 'stitched' together to form a new composite image consisting of all the smaller ones. The result is a high resolution image which can be used to accurately  measure areas and distances.

We also use drones to take aerial photographs of buildings and trees to identify potential bat roosts and other features.

We have a Permission for Commercial Operation from the CAA which allows operations within built up areas.
