The Aristida /Bothriochloa (AB) native pasture community of Central Queensland is a large, predominantly cattle producing region with small areas of degradation (Weston et al. 1981). The area is deficient in production and ecological knowledge, and studies are now assisting to develop sustainable resource management practices. This paper reports on the tree and shrub monitoring of a project aiming to gain an understanding of the regions ecology and communicate pasture management knowledge to land users. The main findings are:

regular burning had no affect on survival of silver -leaved ironbark seedlings

burning can prevent lignotuber regeneration in cleared areas

timing of burning is important for seedling control

burning has little effect on the size or density of existing woody plants
