  • Our Mammal Conservation Strategy in Britain and Ireland

    Our native mammals, alongside all of our native wildlife, are struggling to cope with a range of threats, but often we are able to make a real difference – both species of horseshoe bat are doing well, and the discovery of the pine marten body in Wales in 2012 gives us great hope for the future.

  • Design of the CJM Batbox

    The CJM bat box was designed to imitate niches where crevice dwelling bats might roost; such as a split in a tree trunk or behind loose bark. The three vertical ‘slots’ each of a different width, offers a choice that several species of bat, depending on their size, might use.

  • 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; and to determine the genetic haplotype of Read More

  • Jordan, N. (2011). Strategy for Restoring the Pine Marten to England and Wales

    Although sightings reports and occasional genetic evidence confirm the presence of the pine marten in parts of England and Wales, limited success in their detection despite concerted efforts suggest that they are not abundant and that populations have failed to recover from their historical decline.

  • 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

  • Morris, C. Cool Tower for Lesser Horseshoe Bats

    Lesser horseshoe bats, like all bats living in temperate regions, require a range of micro-environments in their summer roosts. The provision of cooler roosting areas for this species is an important consideration when developing mitigation plans or suggesting enhancements for existing roosts.

  • 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.

  • 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.
