Mangrove ecosystems are known for being the rainforest of the sea. Philippines is bestowed with this naturally rich mangrove ecosystem with diverse floral and faunal species. Despite this natural abundance, mangrove ecosystems are subjected to natural and human induced degradations specifically conversion to fish shrimp ponds that resulted in diminution aside from its effect on terrestrial and oceanic carbon cycling and could also affect its important role in terms of terrestrial and oceanic carbon cycling.

 

This study is conducted to determine the mangrove diversity, distribution and the above-ground biomass and C-stocks in Glan and Malapatan, Sarangani Province.

Purposive sampling is implemented in establishing the plots on both sites. Results show eight (8) mangrove species belonging to four (4) families are observed in both areas.Data also reveal that the mangrove ecosystem in Glan Padidu, Glan is undisturbed. Rhizophora apiculata and Sonneratia alba are found to be dominant on the two sites. Because of the large tree girths and high density of species observed on the studied areas, both forests have the potential to sequester and store large amount of atmospheric carbon. Thus, this study quantifies mangrove tree biomass in view of carbon trading as significant in lessening the effects of global warming.

Works on park lands show that shea tree is a widespread species in the fields in Burkina Faso. There are caterpillars which are rich in proteins and throw out important quantity of dejection on the soil surface.

The aim of this study was to determine the amount of droppings produced by caterpillars and their chemical quality in Koumbia area. The amount of dejection was determined on small plots and expressed as amount of dry matter (DM). Chemical analyzes have focused on the major elements (C, N, P and K). Our results show an average production of 19.34 kg for an average area of 68.47 m2 under a shea tree. We also observe that the production of caterpillar droppings is a function of the shea trees density and fluctuate between 440 and 3 775 kg ha-1. The data of chemical analyzes show that caterpillar droppings have high content of carbon (477.7 g kg-1) and nitrogen (10.8 g kg-1) and low content of phosphorus (0.3 g kg-1) and potassium (0.9 g kg-1).

The amounts of C and N that caterpillar droppings are likely to bring, show that they can cover between 56 and 484 % of annual loss of soil C and fully compensate exports N of major crops (cotton, maize, sorghum) of the study area. The valorization of caterpillar droppings is therefore a way of ecological management of soil fertility of shea parks. However, the C/N (44) of caterpillar droppings suggests further agronomic investigations.

Morales beach is one of the beaches located in the coastal town of Glan, Sarangani Province and noted for its quite enormous coral reef which is continuously degrading. This study was conducted to assess the health status of coral reef ecosystem and to evaluate the physico-chemical parameters of the area. Point Intercept Transect (PIT) method was used to monitor live coral condition and the supporting fauna at a coral reef ecosystem.

Physico-chemical parameters were obtained in situ using a thermometer, refractometer, and a pH meter. The result of the study showed a very low percentage cover of hard corals, no cover percentage of soft corals and high cover percentage of other biota or substrate. The reef areas exhibited poor coral cover with an average of 15 percent live hard corals having family Acropora as the most dominant species (Shannon diversity index of 1.653). Water samples obtained were within the DENR (1990) standards suitable for the optimum growth of coral reefs. The health status of the coral reefs in Morales beach showed a partially disturbed reef due to human intervention. It is greatly recommended to constantly monitor the coral conditions in order to effectively manage and protect the increasing number of Marine Protected Areas (MPA).
