Ecological studies on montane tussock grassland
In 1946 T.G. Sewell conducted an ecological study on montane tussock grassland in the Cass, Craigieburn region and recorded the state of the vegetation. The studies recorded in this thesis were undertaken for the following purposes: 1. To compare a number of different methods of recording the botanical analysis of tussock grassland vegetation. 2. To determine the changes in vegetation which have taken place over the ten year period. 3. To determine the effects of applications of fertilizers containing phosphorus, sulphur and molybdenum on tussock grassland.
