Abstract
This study was conducted to assess the floral composition of the Alno communal mixed forest in the Philippines. A quadrat method of vegetational analysis was used for the assessment of trees, shrubs, saplings, and seedlings. A total of 78 species belonging to 43 families were identified in this communal forest. For the assessment of grasses, herbs, ferns, and other low-lying vegetation, the line intercept method was used. A total of 31 species belonging to 20 families were found using this method. The diversity (Shannon–Wiener) indices of this communal forest are 3.2129 and 2.3870 for the quadrat method and line intercept method, respectively. The most dominant species in this area is Pinus kesiya Royle ex Gordon (Benguet pine) with an importance value of 64.19 %. Endemic species in the area also connote ecological importance, being considered a good indication of the status of habitats and ecosystems of this communal forest.
