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.

Vol. 8, No. 2, p. 233-239, 2016Morales 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.

A rapid marine biodiversity assessment of the coral reefs in Morales Beach
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).
