Analysis of information sources in references of the Wikipedia article "Chestnut" in English language version.
In the coastal areas, the olive groves are tightly interwoven with low maquis, garrigue and steppe, which have been widely grazed and, consequently, burned. On the other hand, low mountains and inland hills have chestnut and mixed deciduous coppiced woods. The actual boundaries between these two different vegetation landscapes can be found at different altitudes according to local climatic conditions; higher (about 1000m asl) in the eastern and southern areas, and lower and close to the sea in the central and northern basin.
