Efficacy of water conservation techniques for the afforestation of watersheds in the scrub zone of Pakistan
Bashir Hussain Shah
ABSTRACT
To evaluate the efficacy of water conservation
techniques for the establishment of forest plantation,
an experiment was laid out at two sites, Kharian and
Raisan (Kohat). Microcatchments, conservation trenches,
gradonii and simple pits were used for planting
Eucalyptus canaldulensiss, Leucaena leucocephala, Acacia
nilotica and A. modesta seedlings. Preliminary results based on the years data
are presented in this article. All the three techniques
proved effective for the establishment of tree species.
Both the survival as well as growth rate of seedlings
planted with water conservation techniques was almost
double as compares to those planted in simple pits at
both sites. At kharian the seedlins of E. camaldulensis
showed highly positive response to water conservation
techniques by attaining three times height of seedlings planted in simple pits. The response of A. modesta was
however, low. A. nilotica suffered frost damage at Raisan.
