Plant Species Preferences of Birds in Lowland Rimu (dacrydium Cupressinum) Forest—implications for Selective-logging
Plant species preferences of birds were determined by comparing the proportional bird use of plant species during direct observations with the proportions of plant species present on point-height intercepts in lowland rimu (Dacrydium cupressinum) forest in North Okarito, Westland. Plant species and bird use of plant species were divided into 5 m height classes, and rimu trees were divided into ...
متن کاملAnalysis of a model currently used for assessing sustainable
Problems are identified in the use of a variant of the Usher matrix model to underpin the harvest of beech (Nothofagus spp.) and rimu (Dacrydium cupressinum) on the West Coast of the South Island. The model has been suggested as a means of determining the harvest that is sustainable in the sense of maintaining the present forest structure, and uses as inputs the size structure and estimates of ...

The study area of 4.4 ha is located at about 100 m a.s.l., and comprises forest with scattered emergent Metrosideros robusta and Dacrydium cupressinum over a canopy of Elaeocarpus dentatus, Laurelia novae-zelandiae, Melicytus ramiflorus, Hedycarya arborea, Knightia excelsa, Weinmannia racemosa, Schefflera digitata and...
متن کاملEcology of the Stoat in Nothofagus Forest: Home Range, Habitat Use and Diet at Different Stages of the Beech Mast Cycle
We studied the ecology of a high-density population of stoats in Fiordland, New Zealand, in the summer and autumn of 1990-91 following a Nothofagus seeding in 1990. Results are compared with findings from the same area in 1991-92, a period of lower stoat density. In the high-density year, minimum home ranges (revealed by radio-tracking) of four females averaged 69 ha and those of three males 93...
متن کاملThe origin of the indigenous grasslands of southeastern South Island in relation to pre-human woody ecosystems
Immediately before human settlement, dense tall podocarp-angiosperm forest dominated the moist Southland and southern coastal Otago districts. Open, discontinuous podocarp-angiosperm forest bordered the central Otago dry interior, extending along the north Otago coast. Grassland was mostly patchy within these woody ecosystems, occurring on limited areas of droughty or low-nutrient soils and wet...
