One way of mapping terrestrial (land) biomes around the world. A biome (/ ˈ b aɪ. oʊ m /) is a distinct geographical region with specific climate, vegetation, and animal life. It consists of a biological community that has formed in response to its physical environment and regional climate. [1] [2] Biomes may span more than one continent.
Mapping a bioregion is considered a specific type of bioregional map, in which many layers are brought together to map a "whole life place", and is considered an 'optimal zone of interconnection for a species to thrive', i.e. for humans, or a specific species such as salmon, and uses many different layers to see what boundaries "emerge" and ...
They are distinct from biomes, also known as major habitat types, which are divisions of the Earth's surface based on life form, or the adaptation of animals, fungi, micro-organisms and plants to climatic, soil, and other conditions. Biomes are characterized by similar climax vegetation. Each realm may include a number of different biomes.
The following is a list of ecoregions in Mexico as identified by the World Wide Fund for Nature (WWF). A different system of ecoregional analysis is used by the Commission for Environmental Cooperation, a trilateral body linking Mexican, Canadian and United States environmental regime.
