An ecological assessment of man made forests in India

Rao K.S., . and Saxena K.G., . An ecological assessment of man made forests in India. pp. 474-487.

The objective of maximizing crop yield over short periods rather than optimizing crop yield on a sustainable basis in the long run had dominated forest management during the last 50 years. It was the need to maximize yield which led to the planting of Eucalypts and Pines instead of indigenous trees like Teak and Sal over large areas. Although there are limitations in comparing the productivity data of different tree species in different plantations it is apparent that exotic tree species may not always be superior in terms of biomass production to indigenous ones. It is the short rotation management invariably associated with these exotics as opposed to longer rotation management of indigenous species which increases the availability of utilizable biomass from the exotic species. Biomass available from multiple harvest through short rotation plantation forestry of Eucalypts over a period of 40 years seems to be lower than the biomass available from a single harvest of indigenous species like sal or teak under longer rotation cycle of 40 years. Exotics are being established on a massive scale and are being managed with harvesting at short intervals

Abstract

The objective of maximizing crop yield over short periods rather than optimizing crop yield on a sustainable basis in the long run had dominated forest management during the last 50 years. It was the need to maximize yield which led to the planting of Eucalypts and Pines instead of indigenous trees like Teak and Sal over large areas. Although there are limitations in comparing the productivity data of different tree species in different plantations it is apparent that exotic tree species may not always be superior in terms of biomass production to indigenous ones. It is the short rotation management invariably associated with these exotics as opposed to longer rotation management of indigenous species which increases the availability of utilizable biomass from the exotic species. Biomass available from multiple harvest through short rotation plantation forestry of Eucalypts over a period of 40 years seems to be lower than the biomass available from a single harvest of indigenous species like sal or teak under longer rotation cycle of 40 years. Exotics are being established on a massive scale and are being managed with harvesting at short intervals
