The post-fire regeneration responses of Triodia wiseana and T. basedowii.

Abstract

The difference between the regeneration responses of two Triodia species from Western Australia's Pilbara region could be exploited in establishing natural firebreaks. Little n known of the biology of most spinifex species. Observations on the post-fire regeneration of Triodia wiwam and I: bmedowii are reported from a study in the Pilbara. It was found that, in the early stages of post-fire growth and under certain conditions, ind~vidual plants of Triodia wiseam achieved a larger size than T hedowii plants. This was attributed to a sprouting response in the former.
