Although undisturbed tropical evergreen forests are often thought to be fire- resistant ecosystems due to lack of sufficiently dry fuel loads (Bond & van Wilgen 1996, Kauffman et al. 1988, Uhl et al. 1988), this myth is rapidly collapsing with the proliferation of recent forest fires throughout south-east Asia (Kinnard & O'Brien 1998, Leighton & Wirawan 1986), Central America (Anon. 1998a), and northern South America (Anon. 1998b) following unusually severe seasonal droughts.
