Laurel forest is a subtropical or mild temperate forest

) may be prominent, or in association.

Setting

The laurel evergreen temperate forest vegetation is characteristic of a climate regime with well defined seasons, but lacking in sharp contrast. The annual temperature variation is mild, without excluding winter frost, and rainfall is abundant well-distributed throughout the year, without a defined dry season. These conditions occur in four different geographical regions:
  • Along the eastern margin of continents at latitudes of 25º to 35º.
  • Along the western continental coasts between 40° and 55° latitude.
  • On islands between 25º and 35º or 40º latitude.
  • In humid tropical montane
    Montane
    In biogeography, montane is the highland area located below the subalpine zone. Montane regions generally have cooler temperatures and often have higher rainfall than the adjacent lowland regions, and are frequently home to distinct communities of plants and animals.The term "montane" means "of the...

. As in any other rainforest, plants of the laurel forests must adapt to high rainfall and humidity. The trees adapted by developing leaves that repel water. Laurophyll or lauroide leaves are characterized by a generous layer of wax, making them glossy in appearance, and narrow, pointed oval in shape with an apical mucro, or 'drip tip', which permit the leaves to shed water despite the humidity, allowing perspiration and respiration from plant. The scientific names laurina, laurifolia, laurophylla, lauriformis, and lauroides are often used to name species of other plant families that resemble Lauraceace. The term "Lucidophyll", referring to the shiny surface of the leaves, was proposed in 1977 by Tatuo Kira.

Mature laurel forests typically have a dense tree canopy, and low light levels at the forest floor. Some forests are characterized by an overstory of emergent trees.

Laurel forests are typically multi-species, and diverse in the number of species represented, as well as the diversity of genera and families represented. In the absence of strong environmental selective pressure, the number of species sharing the arboreal stratum is high, nearly 100 tree species have been described in the laurisilva

), about 20 in the Canary Islands, not reaching the values of tropical forests. This species diversity contrasts with other temperate forest types, which typically have a canopy dominated by one or a few species. Species diversity generally increases towards the tropics. In this sense, the laurel forest is a transitional type between temperate forests and tropical rainforests.

The temperate evergreen and evergreen forests are typically multispecies. Evergreen because the mild climate allows for continuous biological activity, and multispecies for the remarkable diversity of tree species in the vault forestal. Indeed, in the absence of strong environmental selective pressure, the number of species sharing the arboreal stratum is high, nearly 100 tree species have been described in the rainforest laurisilva of Misiones (Argentina

), about 20 in the Canary Islands, not reaching the values of tropical forests yet. It is precisely this multispecies what they deserve the name of rainforest, in contrast to the "forest", Mediterranean forests, temperate deciduous forests etc., which is monospecific with a canopy dominated by one or a few species. In this sense, the laurel forest or laurisilva is a formation of transition between temperate forests and tropical rainforests.

However, despite the large number of species, there is considerable morphological convergence between the different species of trees, especially in the leaves, which correspond mainly to the type "lauroide" (Sweet bay): wide, oval, leathery, glossy. Hence the Latin name given to the training: laurus

The Mediterranean climate is the balance between dry and warm influence of the subtropical anticyclone, hot and dry summer and the polar air stream, Antarctic and Arctic, responsible for carrying rain storms, cool wet winter.
As latitude increases, this increases the impact of the storms, which in its journey from west to east, swept the western coasts of continents, dumping heavy rains as carrying high humidity.
Precipitation multiply if these air masses are crossing mountains in the way. The resulting climate is wetter, but with an annual oscillation of the temperature moderated by the proximity of the ocean.

These are the climatic conditions of Chile between 38 º and 45 º latitude. Rainfall is abundant, from 1500 to 5000 mm according to locality, and are spaced out throughout the year, but still see the influence subhumid Mediterranean with 3–4 months in summer. The temperatures are unchanging enough and mild, without any month the average fall below 5 °C, with values for the warmest month below 22 °C.

The coasts of Brazil and Argentina, between 25 º and 35 º latitude, are under a laurel forest typical weather patterns. This region still falls in the area of influence of the subtropical anticyclone, which this side sends warm air, moist and unstable at high latitudes. During the summer the anticyclone strengthens and increases the flow of moist air mass, which, as it rises and cools, producing heavy rainfall. In winter, remove the cyclone and strengthening the polar air inlet to the west, causing rain-bearing depressions. Overall, the average annual rainfall varies according to locality, between 1,500 and 2,000 mm. The average temperature is around 20-21 °C, with mild winters and moderately hot summers, due to the moderating effect of heavy rains. This softness does not prevent them occur frost and even snow in the higher regions, which is a limiting factor for species from lower latitudes. A climate of these characteristics is classified as humid subtropical, or warm and rainy with warm summers.

The coasts of Brazil and Argentina, between 25 º and 35 º latitude, are under a laurel forest typical weather patterns. This region still falls in the area of influence of the subtropical anticyclone, which this side sends warm air, moist and unstable at high latitudes. During the summer the anticyclone strengthens and increases the flow of moist air mass, which, as it rises and cools, producing heavy rainfall. In winter, remove the cyclone and strengthening the polar air inlet to the west, causing rain-bearing depressions. Overall, the average annual rainfall varies according to locality, between 1,500 and 2,000 mm. The average temperature is around 20-21 °C, with mild winters and moderately hot summers, due to the moderating effect of heavy rains. This softness does not prevent them occur frost and even snow in the higher regions, which is a limiting factor for species from lower latitudes. A climate of these characteristics is classified as humid subtropical, or warm and rainy with warm summers.
