World Ecoregions & Biomes

World Ecoregions
This new map offers a depiction of the 846 ecoregions that represent our living planet. Ecoregions are ecosystems of regional extent. These are color coded on this map to highlight their distribution and the biological diversity they represent. This new map is based on recent advances in biogeography - the science concerning the distribution of plants and animals. The original ecoregions map has been widely used since its introduction in 2001, underpinning the most recent analyses of the effects of global climate change on nature by ecologists to the distribution of the world's beetles to modern conservation planning. In the same vein, our updated ecoregions can now be used to chart progress towards achieving the visionary goal of Nature Needs Half, to protect half of all the land on Earth to save a living terrestrial biosphere.

World Biomes
There are 14 terrestrial biomes. Seven are forested and 7 are not forested. Plant communities in the same biome can appear quite similar in structure but contain very different sets of species. To better illustrate, click on the feature that depicts the eight biogeographic realms. An ecoregion in eastern Peru (Neotropical realm) could look very similar to one in lowland Borneo (Indo-Malayan realm), but the plants and animals would be different.

Protected areas
Scientists now believe that to avoid the worst of the current extinction crisis and to keep temperature rise below 2°C and also avoid negative biospheric feedbacks, as much as 50% of the land and seas must be kept natural. To this end, we can convert the ecoregions map into a tool for measuring our progress towards the goal of half-protected where lands could be under various forms of conservation management and ownership, from the government to indigenous peoples' or privately-held lands. The map presented here intersects the amount of habitat now protected and the amount of unprotected habitat remaining that could be brought under conservation.
Protected areas
Half Protected (green): More than 50% of the total ecoregion area is already protected.
Nature Could Reach Half  (light green): Less than 50% of the total ecoregion area is protected but the amount of remaining unprotected natural habitat could bring protection to over 50% if new conservation areas are added to the system.
Nature Could Recover (orange): The amount of protected and unprotected natural habitat remaining is less than 50% but more than 20%. Ecoregions in this category would require restoration to reach Half Protected.
Nature Imperiled (red): The amount of protected and unprotected natural habitat remaining is less than or equal to 20%. Achieving half protected is not possible in the short term and efforts should focus on conserving remaining, native habitat fragments.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

Moose population in North America

The moose ( Alces alces ) is the largest member of the deer family, characterized by its massive size, long legs, and distinctive broad, palmate antlers found in males. They have a dark brown or black coat and a humped shoulder. Moose are primarily found in the boreal and mixed deciduous forests of North America, Europe, and Asia. They are solitary animals, often found near bodies of water, and are herbivores that feed on leaves, bark, twigs, and aquatic vegetation. Despite their size, moose are strong swimmers and can run up to 35 miles per hour. The moose population in North America is shrinking swiftly. This decrease has been correlated to the opening of roadways and landscapes into this animal's north range.   In North America, the moose range includes almost all of Canada and Alaska, the northern part of New England and New York, the upper Rocky Mountains, northern Minnesota and Wisconsin, Michigan's Upper Peninsula, and Isle Royale.    In 2014-2015, the North American moo

Map of Fox Species Distribution

Foxes are small to medium-sized members of the Canidae family, which also includes wolves, dogs, and other related animals. There are about 37 species of foxes distributed around the world, and they inhabit a wide range of environments, from forests and grasslands to deserts and urban areas. Below is the map of fox species distribution  created by Reddit user isaacSW Here are some of the most well-known fox species and their distribution: Red Fox ( Vulpes vulpes ): The red fox is one of the most widely distributed fox species and is found in North America, Europe, Asia, and parts of North Africa. They are adaptable and can live in a variety of habitats, including forests, grasslands, and urban areas. Arctic Fox ( Vulpes lagopus ): The Arctic fox is found in the Arctic regions of North America, Europe, and Asia. They have adaptations that help them survive in cold climates, such as a thick coat that changes color with the seasons. Gray Fox ( Urocyon cinereoargenteus ): The gray fox
