On average, 1400mm of rain fall here each year, with 424mm (or 30.29%) of that falling during this locations' wettest quarter.

Local Soil

The local soil is primarily composed of Cambisols (Sites 1, 4, and 5) and Nitisols (Sites 2 and 3). The clay was found to primarily be inactive kaolinite.

Additional Notes

This study found that the termites had little impact on the mineralogical properties of the soil, or the particle size distribution. However, it was noted that the interior of the mound contained significantly less clay, and more sand comparatively.

The species listed is that of the pictured mound. Four species were noted in the study: Cornitermes cumulans, Cortaritermes fuviceps, Neocapritermes opacus, and Termes saltans.
