A Note on the Vegetation at Sazina Khali in the Sunderbans

Abstract: The present paper embodies observations on the mangrove vegetation at Sazina Khali, a rather remote spot in the Gangetic Sunderbans, near Port Canning. Near the Forester's outpost Excoecaria agallocha dominates with Ceriopes roxburghiana as the undergrowth. The effect on the vegetation of some clearings made by the forest department is noted. Near by, there is a swamp with almost pure Avicennia and pure stands of Phoenix paludosa occur on higher ground. Thus distribution of dominants forms a sort of mosaic. Vigorous regeneration by mangrove seedlings was evident during September, the period of the visit, Phenological observations are also recorded.

Status of Plant Biodiversity in Mt. Malarayat, Batangas, Philippines

Abstract: The study determined the vegetative structure and assessed the current status of plant biodiversity in Mt. Malepunyo, one of its peaks. Herbarium of its floristic composition served as the baseline for future monitoring and scientific undertakings in the area. The quadrat technique was used to determine the vegetative structure and ecological dynamics of the forest of Mt. Malarayat- Malepunyo. The size of the quadrat was 100 square meters each (10x10 m). A total of 20 quadrats used were situated more or less along the trail to the peak. The study recorded a total of 104 species under 60 families; of which 46 species are indigenous or native to the Philippines; 27 species are introduced; 23 species endemic to Mt. Malarayat; and 9 species were unclassified. Eleven (11) were threatened species included in the conservation priority areas. The flora is composed of 67% trees, mostly from families Moraceae, Euphorbiaceae, Lauraceae, Meliaceae and Rubiaceae. The undergrowth layer includes shrubs (13%), vines (11%) herbs (5%) and ferns (4%). Its potential threats and anthropogenic disturbances include presence of invasive species, impacts of unregulated tourism activities, small scale timber poaching, hunting and land conversion.
