Abstracts |
Four different stands in the northern areas of Pakistan were sampled and analysed using simple ecological methods. The stands included undisturbed natural vegetation and disturbed stands. The disturbed stands are characterized by excessive cutting and felling and overgrazing leading to entirely different structure of plant communities and associated mycoflora. For mycological studies, the roots of plants in the studied stands along with the rhizosphere soil were sampled and processed. It was observed that the types of ectomycorrhizal fungi varied as the forest stands matured. The fungi almost tend to disappear when the forest trees were cut. The number of root tips with ecotmycorrhizae decreased when the stands were disturbed, so was the case with vesicular arbuscular mycorrhiza forming endogonaceous spores number. The weight of water stable aggregates also reduced in the soils of disturbed stands. These disastrous situations then end up with the removal of the rest of the forest regeneration and excessive erosion or removal of the top fertile soil. This could be avoided with proper management of these fungi. |
