Ecologists are more and more being drawn into the duty of addressing difficulties of environmental degradation. they're anticipated to discover options that would result in sustainable source use during the international. In doing so, the robustness of the technological know-how turns into more and more very important, and the matter of extrapolating the result of examine performed inside of what's often a comparatively restricted geographical scope is more and more highlighted. One method of constructing a globally strong ecology contains roughly formal intercontinental comparative reviews, frequently excited about the query of ecological convergence. those experiences are directed at trying out the prediction that comparable actual and different environmental components in several components of the realm, via their selective impacts, will supply upward thrust to ecosystems which proportion com­ mon structural and sensible gains. may still this be real, the predictive energy of ecology constructed inside of the sort of framework may be adequate to resolve comparable difficulties in different places in such biomes. there's a lengthy historical past of such an method in mediterranean­ sort ecosystems, documented in a chain of volumes and their accompanying clinical papers starting with that of Di Castri and Mooney (1973).

1). At this point, live biomass declines as the dominant Pro tea shrubs start to senesce and die. Dead mass continues to increase with post-fire age. As litter accumulates with increasing post-fire age of the vegetation, the probability of fire increases. Very few fynbos stands survive periods of longer than 40 years without fire (Kruger and Bigalke 1984; Brown et al. 1991). 07 (Mitchell and Coley 1987). This value is similar to those obtained in the only other study done in fynbos (Mitchell et al.

Data for South African sites are from Weather Bureau records. Other data are from Miller et al.

Comparisons are made to other fireprone ecosystems, with a view to quantifying the important differences in fuel properties between such ecosystems, and the effects that they have on the resultant fire regimes. 2 The Description of Vegetation as Fuel In this section we describe the framework within which fuel studies were conducted in Swartboskloof as a background to the data presented later. Since fuel studies are rare, and because they vary considerably in approach, it is necessary to review the conventions followed in the description of vegetation as fuel.
