Botanical survey in wooded and herbaceous semi-natural habitats

The aim was to assess the difference in plant communities in three types of wooded and herbaceous habitats (permanent grassland,hedgerow and forest edge). Plants were surveyed in each of these habitats,in 30 landscapes selected according to a gradient of % of woodland. Botanical surveys were conducted in May and June 2016 in forest edges and hedgerows,and in April and May 2015 and May and June 2016 in permanent grasslands. The surveys comprised abundance-dominance records of all vascular plant species according to the Braun-Blanquet scale in three vegetation layers (herbaceous:0–1 m,shrubs:1–3 m and trees:> 3 m). Data were collected along a 25-m transect on each side of the hedgerows,on a 50-m transect along the forest edges,and wandering freely in grasslands.
