POPULATION CHANGES IN ACIDIPHILOUS GRASS- HEATH IN BRECKLAND, 1936-57.

The article presents an analysis of the population changes in Acidiphilous Grass-heath in Breckland, Great Britain,during 1936 to 1957. According to the author, the Acidiphilious Grass-heath are grasslands in Breckland wherein certain species of rabbits are invading. A quantitative data reports that the decrease in plant populations in the Acidiphilous Grass-heath grasslands show the systematic problem basing a valid diagnosis of a plant community on the results obtained. The author further explained that structured community with a dominant, and a community without the dominant, where the species appear to react interdependently to each other, represent bases for extreme views on the nature of the plant community.
