Descripción
was lost due to encroachment for agriculture and aquaculture by the year 1980. Some species are disappearing fast and are considered as threatened. A total of 19 tree species and nine rattan species need immediate conservation measures (Khan 1996). The on-going loss of germplasm is a threat to FGR. High population pressure on land, clearing of forests, exploitation, draining and filling of wetlands, introduction of exotic species, introduction of improved genotypes, pests, improper silvicultural techniques and management and lack of public awareness are some of the major threats to FGR. Poverty and the attitude of the people towards exploitation of natural habitats of plants as free goods also contribute to the loss of germplasm in the country.
