NARRS Data 2007 - 2013

Data collected under the National Amphibian and Reptile Recording Scheme (NARRS) between its inception in 2007 and 2011. Registered volunteers survey random squares to agreed, repeatable protocols in order to generate national estimates of site occupancy for all widespread amphibian and reptile species. Absences (negative results) are also recorded (e.g. a NARRS amphibian survey where no amphibians were found will show in the dataset as no amphibians recorded at that location in that year). A longer description of the protocols can be found at www.narrs.org.uk.
