Impact of Eucalyptus Plantations on water yield

[Ch. Javed Ahmed]

Eucalyptus has been a controversial tree for many years. While it has its benefits, it has some negative impacts as well. The following video posted by Syed mahmood nasir on linked-in on a paired watershed experiment in South Africa, which has conclusively demonstrated that eucalyptus plantations in catchment areas reduce water supply for downstream water use.

No doubt, beside other factors, it is a hard reality but those having interest and believer of eucalyptus are adamant to listen any thing about it. They are the people who are only focusing on target sets in number rather than any biodiversity value. Still there are people who are insisting the wheel despite the facts that people are suffering from mass scale plantation of exotics spp especially in natural areas where the impacts are manifold including pollen allergy etc. when hundreds of thousands people are forced to leave the area till the season is over. It is now high time to differentiate between forests maintained for ecosystem services and plantations raised for industrial uses.

Dear foresters,

The impact of planting Eucalyptus in watershed areas is applicable to Pakistan or world wide...in Malaysia we practiced commercial planting of E. pellita and E. hybrid for timber production in areas set aside for plantation but not in natural forest or watershed areas by several companies in Sabah and Sarawak..to date since the first planting in 2010, about 50,000 ha of both species have been planted for round log production within 7 to 8 years rotation cycle...tq
