Pine Marten Recovery Project

 

Vincent Wildlife Trust, with its 30-year history of pine marten research in Britain, has boosted the struggling marten population in Wales with a small, but significant, number of martens translocated from Scotland.

The rise and fall of the pine marten

In the ancient wildwoods that once blanketed much of Britain, the pine marten was one of our most common carnivores, thriving amongst the diversity of trees and shrubs that offered a year round supply of food and snug tree holes in which to den.

Pine marten numbers declined dramatically during the 19th and early 20th century as a result of the combined impact of continued habitat loss and an increase in predator control associated with the growth in Victorian game shooting estates. Whilst the pine marten population in Scotland is recovering and expanding, the marten population in England and Wales had been showing no sign of recovery and the likely outcome would have been extinction. It was clear that intervention was needed to restore viable populations of this native mammal south of the Scottish border.

The pine marten in Wales

Although very rare, pine martens were still surviving in low numbers in parts of the Cambrian Mountains, Carmarthenshire and Snowdonia. With this evidence of pine martens present in some areas, reinforcement was considered a possibility, focusing on those areas within the marten’s natural range where habitat and other conditions are suitable. ‘Reinforcement’ means releasing individuals into an existing population, to increase population size and genetic diversity in order to improve population viability.

feasibility study was carried out to identify areas in Wales with high habitat suitability for pine martens. Following extensive field surveys, engagement with local communities and stakeholders, and with relevant licences granted, a population reinforcement was carried out.

Between 2015 and 2017, 51 pine martens were captured in Scotland, in areas where there is a healthy pine marten population, under licence from Scottish Natural Heritage. These animals were translocated and released in forestry in mid-Wales. The martens were kept in release pens for a few days once they arrived in Wales to allow them to acclimatise to their new surroundings and allow us to monitor them remotely via camera trap. They were given a variety of food similar to their natural diet.

The translocated pine martens have become established and breeding has been recorded every year since the translocation began.

Having searched high and low for years for pine martens in Wales and without success, it is so heartening to know that these animals are back in their former haunts once more. The work the VWT is doing is absolutely brilliant.”

The pine marten in England

The pine marten population in Scotland is recovering and expanding and pine martens have begun to spread over the English border and re-colonise areas of Northumberland and Cumbria. The rate and success of this re-colonisation will depend on the availability of suitable habitat and the influence of anthropogenic factors, such as mortality on roads.

The VWT is helping to pave the way for the recovery of the pine marten in northern England through our Back from the Brink project. The project is monitoring the re-colonisation of pine martens with help from a network of volunteers, enhancing habitat by installing artificial den boxes to provide resting and breeding sites for pine martens and raising awareness of the species.

While parts of northern England will be re-colonised by the southward expansion of the Scottish pine marten population, pine martens are unlikely to re-colonise southern and central England naturally. As a result, reintroductions are likely to be the best solution if we are to restore pine martens to southern and central England.

In 2016, the VWT began a collaborative project with Gloucestershire Wildlife Trust and Forestry England to embark on the reintroduction of the pine marten to the Forest of Dean in Gloucestershire. Led by Gloucestershire Wildlife Trust, and following a period of research and feasibility studies, the translocation of pine martens to the forest began in 2019.

The pine marten in Scotland

The VWT’s work in Scotland has focused on monitoring the recovery and range expansion of the pine marten population. The Trust undertook the first national pine marten survey of Scotland, England and Wales in the early 1980s. In 2012, the Trust completed a pine marten expansion zone survey in collaboration with Scottish Natural Heritage, to provide up-to-date information on current pine marten distribution. The survey confirmed that the pine marten population has continued to expand its range south and east of the Highlands and has re-colonised many parts of its former range in central and eastern Scotland.

This work was subsequently followed in 2013 by a distribution survey of southern Scotland. This survey found that pine martens are now present in parts of the Scottish borders and other areas south of the Central Belt where they have been absent for almost 200 years.

The reports of both surveys can be downloaded for free: 2012 report and 2013 report.
