Today and this is not an exaggeration, the island has more forested land that in the past two centuries despite of the forest fires in the past few years. This is mainly because large masses of farmland has been abandoned by the farmers and has been quickly turned into forest and also because of the great speed of the island’s reforestation. Irrefutable witness are the vast stepped landmasses on the mountains (former fields) that are now covered by forests.
During
summertime when rain is rare, the northwest winds are the predominate
ones on the island. They affect the climate and separate the island in
three climate zones, the North one that is affected by the winds that
come from the sea and is wet and cool, the south one where the wind
comes from the mountains, dries-up and warms the island and the mountain
zone where lower temperatures prevail along with high moisture. It is
well understood that these zones don’t have clear boundaries and
therefore, depending to the area’s
Samos
has a plottage of 478,2Km2 out of which 69,5% is forest land, 22% is
semi-mountainous and 8,5% is lowlands. Based on data given by the
Agriculture Committee and the Samian Forest Bureau this plottage is
allocate as follows:
Samians mainly cultivate olive-trees. There are estimated to be 1.567.000 olive trees on the island and the plottage that they occupy is up to 90.000 square Kms. 77% of the olive trees are on the South part of the island because olive trees are tenacious against drought and therefore are a unique species for such dry areas.
Citrus trees are much more prosperous in lower altitudes and on arable land that is not greatly affected by the wind. There are plenty of trees along the island but systematic cultivation is mainly in the area of “Mili”, on the south part where land is arable. Fruit-bearing trees are located throughout the island and especially on the north part and on the mountains where you can find cherries and apple-trees, but there are no systematic cultivations.
There
is systematic cultivation of horticultural in the northern part and
mainly in the villages around Karlovasi where arable plains exist but
smaller fields also exist throughout the island. In the southern part of the
island such cultivations face problems mainly because of the wind and
higher temperatures. There are also a few grain and pulse fields
exclusively in the southern part. The Samian pine-forests cover 13,640 hectares or 28,5% of the island’s size. They cover the mountainous area and large portions of the north part along with smaller parts in the south. In the lowlands the “Pinus brutia” type prevails and grows as far as the shoreline but in altitudes higher than 700 meters the specie “Pinus nigra” (black pine) is the dominant one. This species is encountered mainly in central Europe and probably Samos and Peloponnese are the limits of its southern expansion. The biggest forests are located on Ampelos mountain and there are smaller ones on Kerkis mountain mainly on the east and northwest slopes. Until the beginning of the 20th century there were also extensive forests of chestnuts and oak trees but were extinguished by fires and woodcutting.
The
main species of these ecosystems are the holly (Quercus coccifera ), the
lentisk (Pistacia lendiskus), the wild olive tree (Olea oleaster), the
locusts (Ceratonia siligua), the cedar (Juniperus sp.), the pines (Pinus
brutia), the spanish grass (Spartium sp.), the prickly bush (Kalycotomus
sp.), the bramble (Robus sp.), the woodbine ( Lonicera sp.) and many
others. Higher up and where the terrain is decalcified (apart for those
mentioned above and are indifferent to These ecosystems, recover quickly after a fire and quickly sprout. The result is that in a very few years the terrain is recovered, but pines are destroyed and they must be either planted or wait for a long time until they recover again (many times not in full). In rocky and barren terrain usually thorny and brushwood-like bushes flourish. These are the “astouvia” (Poterium spinosum), the savory (Satureia thymbra), oreganon (Origanon sp.), “knoukla”(Cistus incanus), broom-bush (Sarcopoterium spinosum), thyme (Thimus capitatus), “Hinopodia (Genista acanthoclada), scarlet sage (Salbia sp), mountain-tea (sideritis sp.) and many others. These areas exist mainly to the south slopes of Kerkis where the soil is consisted mainly by mountain rubble.
Bushes that grow in such terrain are the rosebay (Nerium oleander) and in great numbers the wicker (Vitex agnus-castus) and others. From the scramblers, you can see prickly bush (Rubus sanctus), supplejack (Hedera helix) and “Arkoudovatos” bush (Smilax aspera).
The
one-year plants flourish in Samos, well-favored by the Samian climate.
Their biological circle starts with the October rains and finishes in
the end of June.
