Abstract

The effect of some properties of soil from large termite mounds (TM) on the vegetation pattern (composition and structure) in dry dipterocarp forest (DDF) was conducted at Mae Ping National Park, Li District, Lumphun province, from July 2008 to June 2009. Vegetation sampling was carried out at 15 termite mounds. Canonical correspondence analysis (CCA) was used to investigate the influence of TM soil on the vegetation pattern. The results showed that Macrotermes annandalei was the dominant termite species that established large termite mounds in the DDF. A comparison of the soil properties between TM and DDF showed a highly significant difference, with higher clay content in the TM soils than in the DDF soils (32.98 % and 16.05 % respectively, p < 0.001) and also in bulk density, soil pH and nutrient content. However, the DDF soils had significantly higher sand content than the TM soils, (53.66% and 39.53% respectively, p < 0.001). The CCA analyses clearly indicated that in the termite mounds, clay content, pH and nutrients were positively related to vegetation pattern; in contrast, sand content and porosity were highly related to the vegetation in DDF. Species diversity in the vegetation on the termite mounds was higher than in dry dipterocarp forest. The dominant species on the TM soils typically found in mixed deciduous forest and the dry evergreen forest were Schleichera oleosa, Walsura trichostemon, Diospyros coaetanea, Protium serratum, Garuga pinnata, Polyalthia cerasoides, Diospyros montana and Casearia grewiaefolia.


Thus, the combination of termite activity and soil properties may play an important role in determining the composition and structure of the vegetation. In addition, the large termite mounds may support high species diversity and nutrient cycling in the dry dipterocarp forest.
