Abstract

The Family of Magnoliaceae is one of the most primitive taxa in the world.  Knowledge of this family is essential for studies on the origin, evolution and systematics of Angiosperms.  There are 223 species belongs to this family in the world and 25 of them are found in Indonesia. This paper explains taxonomy, distribution, and conservation status of the family Magnoliaceae in Indonesia.

Abstract

In the last 100 years, the global mean temperature has increased approximately 0.6oC and is predicted to increase approximately 1.1oC to 6.4oC in the end of 21st century. On the other hand, deforestation still continues with the rate of -5.2 million hectares per year. This global climate change phenomenon in physical dimension has been analyzed in detail; yet its effect to the changes of biodiversity particularly in tropical forest ecosystems is still poorly understood. From the literature review, it is clear that there is correlation between global climate change and tropical forest ecosystems. The effect of climate change to forest ecosystems itself includes species range shifts, species extinction risks, biome shifts, and biogeochemical cycling. Furthermore, the deforestation of tropical forestecosystems also has reverse effects to the global climate change, i.e. is increasing the amount of green house gasses which directly changes the three climatic variables which are the Earth surface temperature, the total precipitation, and the atmospheric moisture convergence.

Abstract

Forest fire is a massive threat to tropical forests, causing various negative impacts on nature and human beings. Forest fires often lead to alterations of forest structure and its functions. This study on tree growth after forest fire was conducted using a simulation model. The model was performed at the individual level of the plant community and built to analyze the potential for tree growth and scenarios for post-fire recovery. Five important tree species from the montane forest of Mount Ciremai were chosen to build the model based on four main parameters: plant growth rate, diameter at breast height (DBH), tree-to-grass competition, and tree-to-tree competition. The scenario for post-fire recovery was simulated by replanting similar species with 5 cm DBH seedlings. Predictions from our model showed that most of the chosen species would recover to their pre-fire condition after 37–50 years. Considering the limitations of competition after replanting, it is suggested to minimize tree-to-tree competition and apply silvicultural treatments to maximize tree growth and community recovery.
