The association between habitat and tree diversity was examined using a tree data collection of 29 plots in the Mediterranean coniferous forest at Divjakë-Karavasta National Park. A total of 75 plant taxa—consisting of 17 orders, 34 genera, 24 families, and 833 individuals—were identified from the field observation. The three most prevalent tree species in the area were Ulmus campestris L. (10.4%), Pinus halepensis Mill. (15.6%), and Pinus pinea L. (30.7%). Pinus pinea L. had the maximum stand density of 256 individual’s ha-1 and the largest base area of 20.36 m² ha-1, with the highest number (22) found in S25. Pinus halepensis Mill. with 130 individuals ha-1 and a basal area of 20.31 m² ha-1, had the second-highest stand density. A few species have dominated the forest structure in all 29 plots, and many species have fewer individuals, according to the Shannon index value (H'=2.35) for the entire research region. The Simpson index (D) data for the full test surface in the study indicates a good degree of variety among the forest trees observed on this surface, with a value of 0.8. The species richness index, which ranges from 0.14 to 1.6 for examined surfaces, shows variation in the measured values. The Berger-Parker Index's overall representative value for the study area is 0.3. The study provides baseline data for the management of protected areas in developing countries such as Albania and illustrates the potential of the in situ method in the conservation of natural resources.
