Contamination of drinking and recreational water bodies by toxic cyanobacteria is a significant water management issue in many countries. Until recently, knowledge of the occurrence of cyanotoxins and species responsible for cyanotoxin production in New Zealand was limited. In this study a total of 266 water and cyanobacterial mat samples collected from 227 different water bodies between 2001 to 2004 were analysed for cyanotox...

The Southern Forest Resource Assessment, scheduled for publication in mid-2002, addresses the status and likely future of forests in the South.

In managed forests, the amount of carbon further sequestered will be determined by (1) the increased amount of carbon in standing biomass (resulting from land-use changes and increased productivity); (2) the amount of recalcitrant carbon remaining below ground at the end of rotations; and (3) the amount of carbon sequestered in products created from harvested wood. Because of the region's high productivity and industrial infra...
