  1. Provide supplementary food to increase reproduction/survival

    A replicated study in 1997–2003 in forest, meadows and farmland in a mountain range in central and southern Slovenia (Jerina 2012) found that in areas where supplementary food was provided, the home-range of red deer Cervus elaphus was smaller. Red deer had smaller home ranges in areas where more supplementary feeding occurred (data expressed as model results). Between 1997 and 2003, twenty-five adult female and 17 adult male red deer were caught across a 2,100 km2 study area. Deer were radio-collared and released, and were relocated at least once a week, during all daylight hours, for at least one year. Annual home range size was estimated for each individual for each full year that it was monitored (total = 73 deer-years from 42 animals). Information on the location of supplementary feeding sites, and the type and quantity of food provided, was collected from a national register of feeding sites and used to model deer home-ranges alongside other relevant variables.
