  • Jordan, N. et al. (2011). The Great North Pine Marten Pursuit Report

    The ‘Great North Pine Marten Pursuit’ surveys were initiated in order to collect pine marten DNA from extant populations of England. They aimed to determine the presence of pine martens in specific areas, and so allow a focussing of future conservation resources in those areas, whilst also determining the genetic haplotype of Read More

  • McAney K. (2010) A pilot study to test the use of hair tubes to detect the Irish stoat along hedgerows in County Galway.

    In Ireland the Irish stoat is considered to be a near-endemic subspecies, with >90% of the global population estimated to occur in the country. This study involved laying plastic baited hair tubes, 10 per 200 metres at 20m intervals, along hedgerows in the bottom left 1km2 of 10 km grid squares across County Read More

  • Messenger, J. et al. (2010). Pine Marten Scat DNA Survey of England and Wales 2008-2009

    In 1995 The Vincent Wildlife Trust (VWT) revived its interest in pine martens and explored a number of different methods of detecting the presence of martens, including scat surveys. During this period the Trust’s experiences led to a growing scepticism about the reliability of the field identification of scats on the basis Read More

  • Morris, C. How the installation of grilles and re-roofing of a building in Dorset have allowed greater horseshoe bats to emerge earlier

    It is well known that vegetative cover close to the entrances of the roosts of both greater and lesser horseshoe bats allows them to leave sites in relative security from predators. As the light level is lower, they can also leave earlier than if they had to cross open ground. However, little Read More

  • Poulton, S. (2006). An analysis of the usage of bat boxes

    This analysis investigates the possibility that batboxes can be used to record the presence of bats in areas where they were previously unknown. The datasets used in this analysis have been derived from the VWT Batbox Database. This holds data from 52 sites collected over 20 years from England, Wales, and Ireland.

  • Poulton, S. et al. (2006). A quality scoring system for pine marten sightings

    Rare carnivores live at low densities and detection problems make cost-effective census programmes over wide areas difficult. We developed a system based on structured interviews to record details of ad hoc sightings of pine martens reported in England and Wales by casual observers in response to targeted publicity.

  • Birks, J. et al. (2005). Diversity of den sites used by pine martens

    Dens are an important resource for pine martens and sites are selected in response to predation risks and energetic constraints. We compiled a sample of 370 pine marten dens to test the hypothesis that a scarcity of sites leads to the use of suboptimal structures.

  • Guidance note on a fur snagging system for pine martens

    A guidance note on a system employing a stretched spring to trap dorsal hairs of pine martens which can then be subjected to DNA analysis. This advice note includes the construction, deployment and maintenance of this system used for collecting hair samples from pine martens as they visit specially designed baiting stations.

  • Birks, J. et al. (2004). Are scat surveys a reliable method for assessing distribution of pine martens?

    Systematic searches for marten feces or ‘scats’ have been used since 1980 for assessing the status of protected populations of pine martens in Britain. This report reviews the recent history of survey programs for pine marten populations in Britain and examines the accuracy of marten scat identification in the field.
