  • Prospects for Pine Martens E-zine November 2009

    Over the summer I have been mainly focusing on establishing, and intensively monitoring, seven sites in the south Lake District. Over these sites I have set up 65 hair-tubes and six camera traps, in order to try and gain evidence of pine martens. So far, the pine martens have continued to elude us but we remain Read More

  • Prospects for Pine Martens E-zine August 2009

    Prospects for Pine Martens is an ambitious project which aims to assess and publicise the status of pine martens. The project explores the options for conservation with decision-makers, trials and establishes methodologies for data collection, and ultimately provides current data on the distribution, status and genetics of pine martens.

  • Fitting a Morris Batslate

    The Morris batslate is a specially designed ‘slate’ that will allow bats access to a roof void. Due to the relatively low cost of materials and labour involved in the construction of a Batslate it is easier to follow these instructions.

  • 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.

  • Shore, R.F. et al. (2003). Spatial and temporal analysis of second-generation anticoagulant rodenticide residues in polecats

    Polecats in Britain are currently expanding their range eastwards from Wales to reoccupy central and eastern areas of England. Second-generation anticoagulant rodenticides (SGARs), to which polecats are exposed by eating contaminated prey, are used more extensively in these central and eastern regions, leading to fears of increased exposure, and possible resultant mortality.
