Eucalyptus is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including Corymbia, they are commonly known as eucalypts. Plants in the genus Eucalyptus have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut".
Reforestation is the natural or intentional restocking of existing forests and woodlands (forestation) that have been depleted, usually through deforestation, but also after clearcutting.
Pinus pinaster, the maritime pine or cluster pine, is a pine native to the Mediterranean region. It is a hard, fast growing pine containing small seeds with large wings.
Afforestation is the establishment of a forest or stand of trees (forestation) in an area where there was no previous tree cover. Many government and non-governmental organizations directly engage in afforestation programs to create forests and increase carbon capture. Afforestation is an increasingly sought-after method to fight climate concerns, as it is known to increase the soil quality and organic carbon levels into the soil, avoiding desertification.
The woodlands of the Iberian Peninsula are distinct ecosystems on the Iberian Peninsula. Although the various regions are each characterized by distinct vegetation, the borders between these regions are not clearly defined, and there are some similarities across the peninsula.
In the late nineteenth century, about 30% of Ethiopia was covered with forest. The clearing of land for agricultural use and the cutting of trees for fuel gradually changed the scene, and today forest areas have dwindled to less than 4% of Ethiopia's total land. The northern parts of the highlands are almost devoid of trees. However, about 45,000 square kilometres of dense forest exist in the southern and southwestern sections of the highlands. Some of these include coniferous forests, found at elevations above 1,600 meters, but a majority of the forestland consists primarily of woodlands found in drier areas of the highlands and in the drier areas bordering the highlands.
The climate and ecology of land immediately surrounding the Mediterranean Sea is influenced by several factors. Overall, the land has a Mediterranean climate, with mild, rainy winters and hot, dry summers. The climate induces characteristic Mediterranean forests, woodlands, and scrub vegetation. Plant life immediately near the Mediterranean is in the Mediterranean Floristic region, while mountainous areas further from the sea supports the Sub-Mediterranean Floristic province.
An epicormic shoot is a shoot growing from an epicormic bud, which lies underneath the bark of a trunk, stem, or branch of a plant.
Sierras de Cazorla, Segura y Las Villas Natural Park is a natural park in the eastern and northeastern part of the province of Jaén, Spain, established in 1986. With an area of 2,099.2 square kilometres (810.5 sq mi), it is the largest protected area in Spain and the second largest in Europe. It was declared a biosphere reserve by UNESCO in 1983 and also a Special Protection Area for migratory birds in 1988.
Cumbres del Ajusco National Park is one of many national parks near Mexico City, DF. The Ajusco is known for its high elevations reaching 3,900 meters (12,795 ft) above sea level and is visible from any part of Mexico city. The park is characterized by pine-oak forests and high mountain grassland. Cumbres del Ajusco means "watered grove peaks", an appropriate name for this mountainous region covered with lush green forest with many flowers due to a fair amount of precipitation. The Balsas and Lerma rivers begin in the heart of the Cumbres del Ajusco.
Quercus pyrenaica, commonly known as Pyrenean oak, is a tree native to southwestern Europe and northwestern North Africa. Despite its common name, it is rarely found in the Pyrenees Mountains and is more abundant in northern Portugal and north and northwestern Spain.
Forest restoration is defined as “actions to re-instate ecological processes, which accelerate recovery of forest structure, ecological functioning and biodiversity levels towards those typical of climax forest” i.e. the end-stage of natural forest succession. Climax forests are relatively stable ecosystems that have developed the maximum biomass, structural complexity and species diversity that are possible within the limits imposed by climate and soil and without continued disturbance from humans. Climax forest is therefore the target ecosystem, which defines the ultimate aim of forest restoration. Since climate is a major factor that determines climax forest composition, global climate change may result in changing restoration aims.
The Canadian forestry industry is a major contributor to the Canadian economy. With 39 percent of the land acreage of Canada covered by forests, the country contains 9 percent of the world's forested land. The forests are made up primarily of spruce, poplar and pine. The Canadian forestry industry is composed of three main sectors: Solid wood manufacturing, pulp and paper and logging. The Forests and forestry are managed by The Department of Natural Resources Canada, the Canadian Forest Service, in cooperation with several organizations which represent government groups, officials, policy experts and numerous other stakeholders. Extensive deforestation by European settlers during the 18th and 19th centuries has been halted by more modern policies. Today less than 1 percent of Canada's forests are affected by logging each year. Canada is the second largest exporter of wood products, and produces 12.3% of the global market share. Economic concerns related to forestry include greenhouse gas emissions, biotechnology, biological diversity and infestations of pests, such as the mountain pine beetle.
Deforestation is a primary contributor to climate change. Land use changes, especially in the form of deforestation, are the second largest anthropogenic source of atmospheric carbon dioxide emissions, after fossil fuel combustion. Greenhouse gases are emitted during combustion of forest biomass and decomposition of remaining plant material and soil carbon. Global models and national greenhouse gas inventories give similar results for deforestation emissions. As of 2019, deforestation is responsible for about 11% of global greenhouse gas emissions. Peatland degradation also emits GHG. Growing forests are a carbon sink with additional potential to mitigate the effects of climate change. Some of the effects of climate change, such as more wildfires, may increase deforestation. Deforestation comes in many forms: wildfire, agricultural clearcutting, livestock ranching, and logging for timber, among others. The vast majority of agricultural activity resulting in deforestation is subsidized by government tax revenue. Forests cover 31% of the land area on Earth and annually 75,700 square kilometers of the forest is lost. Mass deforestation continues to threaten tropical forests, their biodiversity, and the ecosystem services they provide. The main area of concern of deforestation is in tropical rain forests since they are home to the majority of the planet's biodiversity.
The Sierras of Tejeda, Almijara and Alhama Natural Park is a protected area in the Spanish provinces of Málaga and Granada. It contains the Sierra de Tejeda and Sierra de Almijara mountains. The park is mountainous and is partly covered by pine forests at the lower levels, while typical Mediterranean vegetation is found higher up. There is a large number of endemic species.
The Cantabrian mixed forests is a temperate broadleaf and mixed forests ecoregion in southwestern Europe. It extends along the coastal Cantabrian Mountains and Galician Massif of Northern Spain, extending south into northern Portugal, and northwards through the westernmost Pyrenees to southwestern France. The ecoregion extends from the seacoast to the highest peaks of the Cantabrian Mountains. The highest peak is Torre Cerredo at 2,648 meters elevation.
The Southwest Iberian Mediterranean sclerophyllous and mixed forests is a Mediterranean forests, woodlands, and scrub ecoregion in southwestern Europe. It occupies the southwestern Iberian Peninsula, encompassing coastal lowlands and mountains in portions of Portugal and Spain.
The Iberian conifer forests is a Mediterranean forests, woodlands, and scrub ecoregion in southwestern Europe. It includes the mountain forests of southern and central Spain.
The Pyrenees conifer and mixed forests is a temperate broadleaf and mixed forests ecoregion in southwestern Europe. It extends along the Pyrenees mountains which run east and west along the border between France and Spain, and includes all Andorra. The ecoregion extends from the lower slopes of the Pyrenees to its highest peaks, which include Aneto, Posets, and Vignemale.
Forest now covers just over a quarter of Turkey, but 4000 years ago most of the country was forested. The country is reforesting, which is important for the wildlife of Turkey.
