Temporal land use patterns and livestock numbers across several river catchcments. Within DAFM the Land Parcel Identification System (LPIS) division generated a list of herds who had land in each river catchment area for a select number of river catchments from 2014-2020. The departments Animal Identification & Movement (AIM) division provided the bovine and ovine figures for each herd in each year.

It should be noted that the AIM data was generated for herds who had land in each river catchment area. It is likely that some herds also had land outside the river catchment areas. In total AIM were supplied with 26,002 herds to report on across each location and year. 2,198 of these herds were not included in the final dataset because they either did not have cattle in the period, or did not have sheep census returns in the period (or both).
