Olive trees can live for between
300 to 400 years and ancient olive groves contribute considerably to the
ecosystems and to the aesthetics of the agricultural landscapes in which they
are located, particularly in Spain, Greece and Northern Portugal. However, in
some places, the old olive groves are being destroyed. There seem to be two
reasons for this. One is that European Union agricultural policies favour more
intensively farmed olives in higher density, younger plantations. The expense of
harvesting olives is much reduced in younger trees as the slender trunks can be
shaken and the olives collected in this way. Another pressure is growing demand
for ancient trees in the gardens of the wealthy, especially in the Algarve of
Portugal.
This photograph shows a number of
old olive trees in a garden centre near to Faro or Lagos, Portugal. Large trees, complete
with their root and earth base, can weigh up to 20 tonnes and there is variable
success in transplantation. Some estimates consider that the supply of old trees
will last just a couple of years.
