New Forest Pine Marten survey: summer 2021 update

Updated: Aug 2, 2021

Marcus and Russ write:

Wild New Forest are partners in an exciting new project that aims to improve understanding of Pine Marten distribution and habitat use in the New Forest National Park. Since we recorded the first video evidence of Pine Martens in the New Forest in early spring 2016, we have seen a dramatic increase in reports of roadkill specimens and field observations, as outlined in this popular WNF blog from last year:

Marcus is leading on fieldwork for the new project, which sees us partnering with Forestry England and Hampshire and Isle of Wight Wildlife Trust. In the first five months Marcus has successfully recorded Pine Martens on remote cameras at several New Forest locations, and a series of video clips have been uploaded to the WNF YouTube channel at the link below:

We will be producing a survey report for Forestry England later this year summarising the first phase of fieldwork and will provide an overview of the key findings on this blog. In the meantime, the news release issued this week by the project partners is copied below:

Conservationists have confirmed that Pine Martens have established a thriving population in the New Forest in southern England. A team from Forestry England, Hampshire & Isle of Wight Wildlife Trust, and Wild New Forest will be studying them over the next year to find out more about how these rare creatures are living in the Forest.

Pine Martens, a cat-sized member of the weasel family, were once widespread across the UK. Habitat loss and human activity drastically reduced their numbers, with only a small and fragmented population remaining, mostly in the very north of England, Scotland, and parts of Wales. They prefer well-wooded areas with plenty of cover, and largely feed on small rodents, birds, insects, and fruit.

The earliest sighting of a Pine Marten in the New Forest was made in 1993 by the New Forest Badger Group. Over the years, a series of other sightings have been recorded including video of Pine Martens inadvertently captured on hidden cameras set up to monitor other species.

With clear evidence that a population of Pine Martens has now become established in the New Forest the survey team will be assessing the size of the population and their breeding success. They also hope to identify the different habitats and areas of the forest where they are settling.

The team will use a range of techniques to study these mostly nocturnal creatures including the use of hidden cameras. Every Pine Marten is chestnut brown in colour, but each has a uniquely shaped bib – a pale yellow section of fur on its chin and throat. This makes it possible to identify and record every individual, and observing their interactions means the team will also be able to spot family groups.

Leanne Sargeant, Senior Ecologist at Forestry England, said: “It is not often that we are able to talk about wildlife returning to landscapes and re-establishing their populations, and so this is a really fascinating development to study. The New Forest is a unique landscape and a haven for wildlife, and through this work we hope to learn just what makes it such a good habitat for returning Pine Martens.”

Joanne Gore, of the Hampshire & Isle of Wight Wildlife Trust, said: “Pine Marten should be part of the natural ecology of the south of England, but persecution and habitat loss have decimated the population. However, tantalising records over the years have hinted that a population might indeed be once again present in the forest. The Trust are therefore pleased to be part of this joint project with Forestry England and Wild New Forest to establish presence and absence across the New Forest of this charismatic woodland species.”

Marcus Ward, from the specialist conservation consultancy, Wild New Forest, said: “Since we recorded the first video evidence of Pine Martens in the New Forest in 2016, we have been following their progress with great interest. This new project is a wonderful opportunity to assess the status of the New Forest population and will help inform their future conservation.”

The project, part funded by Defra, will share its findings with the national Pine Marten strategy focussing on the recovery of these rare creatures. The survey team are also being supported by the New Forest Badger Group and are keen for other organisations and landowners to get involved in the project.

Forestry England is supporting a range of projects across the UK to help secure the return of Pine Martens to England’s forests and are monitoring populations in the North York Moors, Kielder Forest, and the New Forest. It is also taking part in England’s first reintroduction of Pine Martens in the Forest of Dean. Having started in 2019, this project reached a major milestone in the summer of 2020 with the birth of the first kits.
