Montane evergreen forest is the rarest evergreen for-
mation in Thailand and also one of the richest forma-
tions for biodiversity (Whitmore, 1984). Montane
species have also been found to be disproportionately
threatened both in Asia (e.g. Brooks et al., 1999) and
elsewhere (Renjifo et al., 1997). We wanted to find out
the rates of fragmentation of this forest type in a pro-
tected area and what impacts this might be having on
wildlife. Although aerial photographs and satellite ima-
ges allow comparison between past and present forest
extent, there is no data available on the original wildlife
diversity associated with these past conditions. One way
to surmount this problem is to select analogue sites
where conditions are similar but differ in extent of
human impact. This was the approach taken in this
study. We selected two comparable areas of evergreen
montane forest that were subject to different degrees of
human interference and compared fragmentation extent
and rates and wildlife response in these habitats. Two
contiguous wildlife sanctuaries were selected and these
will be discussed in more detail below.
