TUSSOCK GRASSLANDS IN THE MIDDLE RAKAIA VALLEY, CANTERBURY, NEW ZEALAND

Botany Division, Department of Scientific and Industrial Research, Christchurch

Abstract Phytosociological analyses are presented of the three major tussock grassland communities found today in the middle Rakaia valley: (1) snow-tussock grassland dominated by either the tall tussock Chionochloa flavescens or the tall tussock C. rigida, (2) red-tussock grassland where the tall tussock C. rubra is abundant and (3) fescue-tussock grassland where Vestuca novae-^elandiae is characteristic. Floristic data are also presented for some severely degraded grassland communities. The zonation and history of these grasslands are discussed, in particular the recent origin of fescue-tussock grassland from former tall-tussock communities.
