Lochaber wild boar/feral pig camera trap survey, 2015
NatureScot
Description
A pilot survey of wild boar/feral pig was undertaken to find out how feral pigs are using four different habitat types (Native woodland, Plantation woodland, Young woodland, Open habitats) within the Glen Garry study area, where the species is known to be well-established in the wild. The dataset includes records of wild boar/feral pig and other wild mammals recorded by camera-traps.
Geographic Description
The survey covered parts of the National Forest Estate in the Glen Garry area of Lochaber, Inverness-shire
Purpose
The survey was undertaken to find out how feral pigs are using four different habitat types (Native woodland, Plantation woodland, Young woodland, Open habitats) within the Glen Garry study area. The data collected can also be used to estimate pig density within the woodland, although estimates of population density are restricted in accuracy by the limited number of camera traps used and the lack of information on range covered by individual animals.
Data quality
Records are of animal images captured by camera traps, so there is a very high degree of confidence in the data. Unidentifiable images and images of birds and domestic livestock were excluded from the dataset. As the study was primarily set up to establish habitat use, estimates of population density are restricted in accuracy by the limited number of camera traps used and the lack of information on range covered by individual animals.
Methods
Sampling was by setting camera traps in a grid within ten randomly-selected 1 km2 squares at a density of 20 traps per square in a grid with trap locations at least 40 m apart. Unsuitable squares (e.g. too steep to safely access, sensitive breeding birds, harvesting areas) were excluded, and camera points falling in unsuitable locations (e.g. waterbodies) were shifted to nearby suitable locations within the same square, giving a total of 360 camera locations. Cameras were set at each location for 13-18 days, giving a total of 2960 days recording. Each square was assigned to one of the four habitat types if it contained >20 ha of that habitat. Some squares were assigned to more than one habitat.
