Phumdis in Loktak Lake are unique floating islands composed of vegetation, soil, and organic matter. They exist in a waterlogged, anaerobic environment. Gleization is a soil formation process that occurs under prolonged waterlogged (anaerobic) conditions. It involves the reduction of iron compounds, often resulting in characteristic grayish or bluish-gray colors in the soil profile. This process is typical in wetlands and swamps, fitting the environment of the Phumdis. Laterization occurs in hot, humid climates with intense leaching. Podzolization occurs in cool, humid climates under coniferous forests. Calcification occurs in arid/semi-arid climates with calcium carbonate accumulation. Therefore, gleization is the most relevant soil formation process associated with the waterlogged conditions where Phumdis develop.

Gleization is a soil-forming process characteristic of poorly drained or waterlogged environments like wetlands, involving the reduction and segregation of iron and manganese under anaerobic conditions.

Phumdis cover a significant portion of Loktak Lake and are crucial to the ecosystem. The Keibul Lamjao National Park, home to the endangered Sangai (Brow-antlered deer), is situated on the largest phumdi.
