Vegetation is a collection of plants that usually consist of several species and live together in one place. Vegetation analysis is a way of studying the composition (component type) and the shape (structure) of vegetation or vegetation communities. Forests are the most important habitat component of life, hence the condition of plant communities within the forest, whether plant species composition, species dominance, density or closure of the canopy should be measured. The island of Sumatra is one of the most diverse ecoregion regions in the world. World Wildlife Fund for Nature (WWF) as one of the world's conservation organizations incorporates mountainous rainforest as a conservation area. The Sumatra mountain forests are one of the 200 critically endorsed ecoregions and a priority of global conservation. Mount Dempo is a protected forest area located on a cluster of hills line the island of Sumatra. This mountain has a height of 3159 asl (above sea level) and is the highest mountain in the area of South Sumatra. This study aims to determine the diversity of plants in the protected forest vegetation of Mount Dempo, Pagar Alam City, South Sumatera. Vegetation analysis was done by purposive sampling with bitterlich method, i.e measurement done on plot measuring 2x2, 5x5, 10x10, and 20x20 m.

The early developmental stages of fish are particularly sensitive. Plant extract with its content can have a good or bad effect on this embryonic phase, depending on the concentration and period. The impact can range from disruption of embryonic development to death. Disorders of embryo development commonly observed are the hatching rate, delay or premature hatching, survival rate, heartbeat rate, morphological changes, and body malformations. The chorion does not fully protect the embryo against plant extract because the content of plant extract has a small specific gravity to enter and penetrate the chorion layer. The variety of plant extract contents can make the results of research less predictable so that the single material contain is felt to have a more accurate impact on natural medicine research.
