Natural Communities of North Carolina

A natural community is a distinct collection of plants and animals (and fungi and bacteria) associated with each other and with their physical environment. North Carolina harbors over 300 unique natural communities, which can be grouped into about 30 categories (listed below).
 
Natural communities consist of both biotic (living: plants and animals) and abiotic (non-living: soil and water) factors. Plants tend to locate where their needs for soil, water, and space are met. Animals follow similar needs, which include safety and a reliable food supply. The combination of these biotic and abiotic factors makes each of North Carolina’s natural communities unique. 
 
Each natural community is most likely to be found in its preferred ecoregion – mountains, piedmont, or coastal plain – and its preferred circumstances – high and dry, low and moist, or a combination. It is North Carolina’s varied topography (sea level to tallest mountain on the east coast), soil (sand to clay to rock), and moisture (rivers, ocean, and rainfall) that allow for the rich biodiversity we enjoy.
 
Once you become familiar with a few of North Carolina’s natural communities you will notice them around your neighborhood and across the state.  Some are familiar faces in many parts of eastern North America’s Temperate Deciduous Forest biome, while many can be found only in North Carolina. They are home to our native species and the building blocks of whole ecosystems that cycle nutrients and clean the water and air.  Different natural communities can be found close together in the same landscape like distinct neighborhoods within a city.
