Natural vegetation  is the plant cover that would establish itself in an area without  human interference. Many areas of the earth have been modified by humans but large  areas of natural vegetation still exist in more inaccessible areas.  The life form of a plant refers to its physical structure, size and shape.  Lifeforms  include trees, shrubs, lianas and herbs.  Habitat  refers to the conditions of slope, water drainage, and soil type that influence  the vegetation cover.  Water availability  is one of the most important factors influencing plant growth.  Xerophytes are plants adapted to dry conditions.  Temperature  affects physiological processes in plants. Plants have a temperature  range within which they can survive as well as optimum temperatures for each of their

Unformatted text preview: functions. Ecological succession is a development sequence in which plant communities succeed one another as they progress to a stable climax, the most complex community of organisms possible in an area. Succession starts with pioneer species that can survive in harsh conditions. These pioneers moderate the harsh conditions and gradually other species move in. Disturbances that can interrupt the sequence include fires, insects, disease and human activities such as cutting and clearing. Biomes are the largest recognizable subdivision of terrestrial ecosystems. These include the forest, savanna, grassland, desert and tundra biomes....
