The forests are home of various species of plants, animals and insects, our future depends on them.
Forests influence rainfall and soil water evaporation, helping to stabilize global climate.
Temperate forests, tropical coniferous or deciduous, together maintain life on earth.
Trees help to conserve soil, prevent desertification, protect coastal areas, absorbing CO2 from the atmosphere. Loss of natural forests help global emissions growth. Reducing deforestation is a method of reducing emissions. World deforestation reached 7.3 million hectares, Africa and South America have the largest net loss of forests.
People contribute to emissions of carbon dioxide in two ways: the burning of fossil fuel and forest conversion into agricultural land or territories for other uses.
Planting and natural expansion of forests help reduce lossestheir forests.
Planteza campaign for the planet: one billion trees encourage tree planting in four key areas: (i) damaged natural forests and wilderness, (ii) farms and rural areas, (iii) sustainably managed plantations, and (iv) urban areas.
To offset the loss of trees would be planted over the past decade 130 million hectares of forest.
World Agri-forestry Center (ICRAF) recommend planting hardwoods in areas where water scarcity is a problem. These trees consume less water than evergreen trees during periods of drought.
Plant indicators of land rich in nutrients (nitrogen put: Atriplex patula, Capsella bursa-pastoris, Chenopodium album, Galinsoga parviflora, fumaric officinalis, Mercurialis annua, Solana nigrum, Thlaspi arvense, Urtica dioica, Urtica urens.
Types of forests
Classification depends mainly forests position, distance from equator, altitude and climate.
Tropical forests - all year round temperatures are high and precipitation. Tropical moist forests are found near the equator. In tropical forests there is a season of drought. Most trees have crown umbeliforma.
