A project containing photos from camera traps targeting pine martens
This project is available for public Spotting but Trapping is restricted. If you would like to join this project as a Trapper please contact us at info@mammalweb.org.
Gloucestershire Wildlife Trust, Forestry England, Forest Research and Vincent Wildlife Trust are collaborating on a project to reintroduce pine martens to the Forest of Dean. In September 2019 the first individuals were released in to the forest. Translocated animals were collared and radio-tracked when first introduced to the Forest of Dean, but most of these collars have now naturally fallen off. In addition to this, several of the introduced females gave birth to kits in 2020. This means that only way to track many of the individuals now living in the Forest of Dean is through camera trapping. This sub project contains photos captured by camera traps collected in collaboration with the Gloucestershire Wildlife Trust.
Pine martens have a 'bib' of creamy-yellow fur that extends from under their chin down their chest. However, the size, shape and pattern of this bib fur varies between animals, with no two pine marten bibs being the same. This means that we can use this bib patterns to identify and monitor individuals. Identifying pine martens individuals from camera trap footage helps us to monitor the population and understand where particular pine martens have set up territory, which other individuals they interact with, whether they are likely to have bred and how many individuals in total are in the population.
Each pine marten is given a unique identification name when they are translocated. Each ID begins with ‘FD’ which stands for Forest of Dean, followed by a number relating to the order they were released in. This ID name allows us to differentiate between martens introduced to Wales who’s names begin with ‘PM’ standing for pine marten and those originally released in the Forest of Dean, as it is likely these populations will join up in coming years! When spotting on this project you will see the normal species list on the right, but also a tab containing profiles of different pine marten individuals known to be living in the Forest of Dean. Each profile contains some information about that animal along with images and a diagram of it's bib markings. This can be used to help identify whether or not that individual is present in a camera trap photo or video. Identifying individual pine martens can be tricky, so please check out our top tips below to help you get started.
