Analysis of information sources in references of the Wikipedia article "Olive" 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.

Anni dopo, furono accantonati in favore dei gelsi, così da promuovere l'allevamento dei bachi da seta. Verso la fine degli anni '80 del secolo scorso, la coltivazione dell'olivo è stata ripresa[In 1494, 1600 and 1709, frost destroyed almost all the olive trees. Later, they were replaced by mulberry trees to promote the breeding of silkworms. Olive cultivation in Ticino was revived at the end of the 1980s]
