Of the 5 1/4 million acres of total occupied land in the Wellington district nearly 4 million acres are in sown pasture, the remainder being bush, natural tussock grassland, scrub and secondary growth. Of this sown area a large proportion comprises hill-country farms running sheep and beef cattle and carrying an average of 1 to 2 sheep per acre. From the sheepfarming point of view the Wellington district is of major national importance, contributing nearly 22 per cent. of the total sheep population and almost 19 per cent. of the total beef cattle. The region as a whole carries the heaviest concentration of stock of all New Zealand.

The moss flora of the Auckland Islands (50°40′ S latitude and 166°00′ E longitude) consists of 145 species and seven varieties in 75 genera. A detailed description of the habitat of each taxon is given. The vegetation, climate, and history of the islands, as they pertain to bryology, are reviewed. Four broad vegetational zones are recognized: forest, scrub, tussock grassland, and tundra as well as areas of herbfields and mires. Phytogeographically, the most common pattern of distribution is Australasian with 29% of the moss species found in both New Zealand and Australia. Other patterns are common as well. Discussion is orientated toward species richness variability in polar regions. The origins and adaptations of mosses in subantarctic landscapes are reviewed and correlations drawn between particular growth forms and individual moss floras and habitats.

Abstract In two trials near Lake Tekapo, one started from sown binary mixtures of 14 different legumes, of which Lupinus polyphyllus was one, was cross sown with 16 different grasses, while in the other trial L. polyphyllus and Trifolium hybridum were over-drilled across established swards of previous 25 different grass and legume species. In both L. polyphyllus persisted, increased and spread by seeding in the presence of repeated mob grazing by sheep to become the dominant species over two decades. Keywords: New Zealand, rangeland pasture development, Lupinus polyphyllus, Bromus inermis.

AbstractClay mineralogical differences between eight soils in South Island, New Zealand, are related to differences in climate, vegetation, and formation time. Alteration of chlorite follows the sequence chlorite→interlayered hydrousmica→chlorite-swelling chlorite→chlorite-vermiculite, with increased weathering leading to the destruction of the chloritic layers. Mica (muscovite) follows two alteration sequences depending on the overlying vegetation. Under tussock grassland the sequence is mica→mica-vermiculite→mica-beidellite→beidellite. This sequence is also followed under beech forest, together with the sequence of mica→vermiculite→beidellite, with pedogenic chlorite forming when the pH is > 4·5. All but one of the interstratified products (the interlayered hydrous mica) appear to be based on a 1:1 regular interlayering of the two components.
