دراسة تأثير الحواف الحراجية في التنوع الحيوي النباتي : مثال من غابة تلة (طرطوس سورية)‎

الملخص EN

This research has been conducted in Tallee Forest in the governorate of Tartous (Syria) during autumn 2013 and spring 2014.

It aims to understand the forest edge effects on the plant species diversity in a region where forests are significantly fragmented.

Vegetation has been surveyed through three transects of 10 meters along the edge between the forest and agricultural lands, with 10 m distant between them.

All the plant species crossed with transects have been recorded.

This procedure has been repeated at: 1، 2، 5، 10، 20، 50 and 100 m from the first line and in parallel to it.

Diversity was estimated using species richness and Shannon index and the similarity between lines was calculated using the Jaccard index.

The forest edge effect on species richness and types was clear in this study but the depth of this effect was limited since it started to decrease at the first meter from the edge to disappear almost five meters from it, the edge effect on species richness was clearer than on their relative abundance.

The study showed the effect of small forest gaps (forest routes and roads particularly) in the composition of the forest.

This study is among the very rare studies dealing with forest edge effect in Syria, which can establish the base for more extensive studies and can contribute to the biodiversity conservation in these forests.
