One aspect of monitoring grazing systems is the condition of the natural resource. Photos show broad changes such as the reduction of rubber vine (Cryptostegia grandiflorum) byfire. Estimates of species composition on north-east Queensland Aristida/Bothriochloa, spinifex (Triodia spp.) and black speargrass (Heteropogon contortus) community sites in 1992 and 1995 show more subtle changes often missed by photos. All except the speargrass site had reductions in decreaser perennial grasses. The intermediate perennial grass increased only on the spinifex site, while increaser perennial grasses increased on all sites. The two monitoring methods are contrasted. Interpretation and use of this information in management is discussed.
