Short-term Effects of Rabbit Grazing on a Degraded Short-tussock Grassland in Central Otago
Despite 120 years of rabbit (Oryctolagus cuniculus L.) control in New Zealand, there is a surprising dearth of quantitative information on the damage rabbits cause to agricultural systems and the environment. Research and debate on rabbits have traditionally centred on the various technical options available for their control, and their cost efficiency. Little attention has been paid to the env...
متن کاملRapid short-tussock grassland decline with and without grazing, Marlborough, New Zealand
Species abundance, species richness, and ground cover were measured over 10 years on nine paired grazed and exclosure plots in short-tussock grassland in the early stages of invasion by Hieracium species. With and without grazing, H. pilosella and H. caespitosum increased markedly and H. lepidulum increased locally. In contrast, 50% of all other common species and species groups, and total, nat...
متن کاملChanges in vegetation states in grazed and ungrazed Mackenzie Basin grasslands, New Zealand, 1990–2000
Changes in vegetation from 1990 to 2000 were examined at 10 high country localities, representing four grassland types: fescue tussock (Festuca novae-zelandiae), snow tussock (Chionochloa rigida), red tussock (C. rubra), and silver tussock (Poa cita). At each locality, three treatments were established: ambient sheep+rabbit grazing, rabbit grazing only, and no grazing. The mutivariate methods o...
متن کاملSimulating rotational grazing management.
Dairy systems predominantly based on rotational grazing are notoriously hard to manage. In order to ensure profitability, this type of production requires quite good organisation, planning, and operating capability on the part of the farmer. A simulation-based decision support system, called SEPATOU, has been developed for this purpose. At the core of the decision support approach lies an expli...
متن کاملAlfalfa Grazing Management
Grazing alfalfa with dairy or beef animals is not a common practice in California or even in the United States. Although a limited number of alfalfa acres are grazed in the humid Midwest and East, it is rare in the West, and the ruminant alfalfa forage systems throughout the United States consist of hayand haylage-based harvest methods. However, there is increased interest in grazing in North A...
