Abstract

Sondaken Village has three mangrove zones, each with its own type of plant. The first zone, facing directly towards the sea, is dominated by Avicennia sp. The second zone, in the middle, is characterized by Rizophora sp. The third zone, closer to the land, is predominantly Bruguiera sp. Mangroves have different levels of growth, including seedling level, stake level, pole level, and tree level. The purpose of this study was to determine the types and growth levels of mangroves within its zonation in Sondaken Village, which is part of Bunaken National Park Area. This was done using exploratory and descriptive survey methods, by creating 3 plots in each zone from the edge to the center, with sizes of 10x10 m2, 5x5 m2, and 2x2 m2. The research found that mangrove in Sondaken Village consist of Avicennia sp, Rizophora sp, and Bruguiera sp, with the number of individuals per species being 124, 133, and 113 individuals respectively. Each type of mangrove has different growth levels and numbers.

Abstract

Turtles They are among the world's protected animals and one of the rare, almost extinct species. The preservation of their habitat and knowledge of the traits of turtle-friendly habitats are two ways that the rescue and protection of these turtles must go on. For rescue operations, turtle sustainability, and sustainable coastal management, research is being conducted on the features of the turtle nesting habitats on Popareng Beach. This research aims to determine the characteristics of turtle nesting habitats and identify the parameters that hinder turtles from nesting at Popareng Beach, Tatapaan District, South Minahasa Regency. The method used in this research is the descriptive-exploratory method. With characteristic parameters consisting of beach width measurement, beach slope, sand temperature, sand humidity, sand texture, beach vegetation, and the presence of predators. From the research results, it shows that station 1 and station 2 have results that are suitable for turtle nesting habitats, with values obtained at station 1 being 88.33% and station 2 being 92%. Meanwhile, at station 3, with an evaluation score of 72%, it is considered fairly suitable and the station has tolerable limitations.
