Ecoregions, short for ecological regions, are areas with similar environmental resources. They often have common geographic features such as mountains or watersheds, but their delineation is also based on additional biological, geological, and climate-related patterns. This blog focuses on world geography with attention to ecoregions. I am posting information about different ecoregions. Most descriptions are based on a map area of ten degrees of latitutude and variable longitude depending on distance from the equator. Each map comes with a description of the environment and scientific and cultural points of interest. Special attention is paid to world heritage sites, wetlands of international importance, national parks and other special and unique places.
