Tropical forestTropical forests are forestedecoregions with tropical climates – that is, land areas approximately bounded by the tropics of Cancer and Capricorn, but possibly affected by other factors such as prevailing winds. Some tropical forest types are difficult to categorize. While forests in temperate areas are readily categorized on the basis of tree canopy density, such schemes do not work well in tropical forests.
TreePerennial woody plant with elongated trunkCommon ash (Fraxinus excelsior), a deciduous broad-leaved (angiosperm) treeEuropean larch (Larix decidua), a coniferous tree which is also deciduousIn botany, a tree is a perennialplant with an elongated stem, or trunk, usually supporting branches and leaves.
Global Forest Resources AssessmentThe Global Forest Resources Assessment (FRA) reports on the status and trends of the world's forest resources. It is led by the Food and Agriculture Organization of the United Nations (FAO).
Temperate rainforestTemperate rain forests are rain forests with coniferous or broadleafforests that occur in the temperate zone and receive heavy rain.
Terrestrial ecosystemTerrestrial ecosystems are ecosystems that are found on land. Examples include tundra, taiga, temperate deciduous forest, tropical rain forest, grassland, deserts. Terrestrial ecosystems differ from aquatic ecosystems by the predominant presence of soil rather than water at the surface and by the extension of plants above this soil/water surface in terrestrial ecosystems.
EcosystemCommunity of living organisms together with the nonliving components of their environmentLeft: Coral reef ecosystems are highly productive marine systems. Right: Temperate rainforest, a terrestrial ecosystem.An ecosystem (or ecological system) is a system formed by organisms in interaction with their environment, where the biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal factors.

Subarctic climateClimate characterised by long, usually very cold winters, and short, cool summersSubarctic climate worldwide as of 1991-2020, using the −3 °C (27 °F) threshold for the coldest month. The subarctic climate (also called subpolar climate, or boreal climate) is a continental climate with long, cold (often very cold) winters, and short, warm to cool summers.
In situIn situ is a Latin phrase meaning 'in the place' or 'on site', derived from ('in') and (ablative of situs, lit.'place'). The term refers to studying or working with something in its natural or original location rather than moving it elsewhere. This approach preserves environmental factors and relationships that might be lost when materials or specimens are relocated to controlled settings.
Food and Agriculture OrganizationSpecialized agency of the United NationsThe FAO Food Price Index (1961–2025). The average for 2014–2016 is set at 100. Real NominalThe Food and Agriculture Organization of the United Nations (FAO) is a specialized agency of the United Nations that leads international efforts to defeat hunger and improve nutrition and food security. Its Latin motto, fiat panis, translates to "let there be bread". It was founded on 16 October 1945 in Quebec City, Canada.
Primary productionIn ecology, primary production is the synthesis of organic compounds from atmospheric or aqueous carbon dioxide. It principally occurs through the process of photosynthesis, which uses light as its source of energy, but it also occurs through chemosynthesis, which uses the oxidation or reduction of inorganic chemical compounds as its source of energy. Almost all life on Earth relies directly or indirectly on primary production.
SubtropicsGeographic and climate zoneAreas of the world with subtropical climatesThe subtropical zones or subtropics are geographical and climate zones immediately to the north and south of the tropics. Geographically part of the temperate zones of both hemispheres, they cover the middle latitudes from 23°26′08.9″ (or 23.43581°) to approximately 35° to 40° north and south. The horse latitudes lie within this range.
