Scientists have underlined that the increasing abundance of roe deer appears to be having an impact on woodlands. Indeed, official data collected from the 35 sites of the United Kingdom have shown an apparent relationship between increasing roe deer density and a decrease in shrub diversity and cover. More importantly, research and findings have laid emphasis on the fact that overgrazing by deer had a knock-on effect that undermined woodland ecologies. In addition to this scientific researchers have mentioned that deers often have specific impacts on vulnerable habitat as well as agriculture and forestry specially since the animals tend to range over large areas and need to be managed on a landscape scale, with collaboration between landowners. It is crucial to note that ecologists have warned that the threat from deer to woodlands consist of a number offactors - a reduction in the growth and density of saplings, bark damage and a change in the composition of under-storey vegetation. In-depth research have demonstrated that there are more than 74, 000 roe deers which are killed every year...
