sikadeer: Sika deer pellet data from southern Scotland

Description Format Details References


Because sika deer spend most of their time in woodland areas, abundance estimates are based on pellet group counts. Line transect methods were applied to estimate deer pellet group density by geographic block.


A data frame with 1923 rows and 11 variables.
