The vertical stratification of a community is determined largely by the life forms of plants their size , branching and leaves which is influenced by the vertical gradient of light. Vertical classification of vegetation in a forest showing the tree, shrub and herb layers and the forest floor.
Vegetation classification is the process of classifying and mapping the vegetation over an area of the Earth's surface. Vegetation classification is often performed by state based agencies as part of land use, resource and environmental management. Many different methods of vegetation classification have been used.

An ecological vegetation class (EVC) is a component of the vegetation classification system developed and used by the state of Victoria, Australia, since 1994, for mapping floristic biodiversity.

Ecological classification or ecological typology is the classification of land or water into geographical units that represent variation in one or more ecological features. . Traditional approaches focus on geology, topography, biogeography, soils, vegetation, climate conditions, living species, habitats, water resources, and sometimes also anthropic factors.
The U.S. National Vegetation Classification (NVC or USNVC) is a scheme for classifying the natural and cultural vegetation communities of the United States.The purpose of this standardized vegetation classification system is to facilitate communication between land managers, scientists, and the public when managing, researching, and protecting plant communities.
One of the earliest attempts to classify the life-forms of plants and animals was made by Aristotle, whose writings are lost.His pupil, Theophrastus, in Historia Plantarum (c. 350 BC), was the first who formally recognized plant habits: trees, shrubs and herbs.
The following is the list of the 286 plant communities which comprise the British National Vegetation Classification (NVC). These are grouped by major habitat category, as used in the five volumes of British Plant Communities, the standard work describing the NVC.
