Roe deer (Capreolus capreolus L.) browsing effects and use of chestnut and turkey oak coppiced areas

"Introduction Roe deer (Capreolus capreolus) browsing pressure on vegetative regeneration of Turkey oak (Quercus cerris) and chestnut (Castanea sativa) and roe deer use of coppiced areas were investigated. . . Methods In the Apennines, Central Italy, six experimental areas were chosen, where fenced (ungulate access excluded, protected P) and non-fenced (ungulate influence present, non-protected NP) plots were established after coppicing. From 2002 to 2005, each plot was surveyed twice a year, and number, biomass, collar diameter, and total height of the sprouts were measured. . . Results Roe deer had a different effect on the re-growth of Turkey oak and chestnut sprouts. After 4 years, chestnut did not show any browsing-related damage, while in Turkey oak, biomass and height of the sprouts in fenced plots significantly differed from those in non-fenced plots. The results agreed with an experimental browsing index. The outcome is relevant because it represents a quick and reliable field tool to assess the impact on a larger scale, where analytic and quantitative approaches cannot be applied. The locations of 62 adult radio-collared roe deer confirmed an increase in the use of coppiced areas. A utilisation index showed more frequent use of these areas during and after forest work. Contrary to common opinion, logging seemed to attract roe deer in coppiced areas as the vegetation biomass at their disposal increased."
