ABSTRACT

Study on the status of predator and prey in dry dipterocarp forest was
carried out at Sakaerat Environmental Research Station, Nakhon Ratchasima for
one year period from December, 1983 to November, 1984. Road side counts were
used for census method. Only birds and mammals found along the census routes
were recorded. From the results of study, it was found that the total number of
birds and animals was 106 species which was composed of 14 species of predators
and 92 species of preys. Both predator and prey were mainly consisted of birds
with the number of 12 and 86 species respectively. The mammals were found to be
predators only 2 species and preys 6 species. The predators and prey were
abundant in January with the number of 5 and 51 species respectively but the were rarely observed in July when the number of predator
was only 1 species and prey only 16 species. However, in this area the
immigration of bird predators were observed in January, August and December
while the bird of preys were found in January to March, June and September to
December.

From 106 species of predators and prey observed 98 species, 32 families
and 11 orders of birds were grouped while 8 species, 6 families and 6 orders of
mammals were classified.

The results of study seem to concluded that the
environmental condition of dry dipterocarp forest play direct effects on both
species and number of predator and prey species. Predators seem to increase
when preys increase. Predators are expected to have no influence in controlling
both the species and number of preys in this study area.
