取樣方法

Six transects of point-count stations were established in 2015 at sites representing a broad range of distinct vegetation types (e.g., grasslands mixed with exotic trees, podocarp, beech, and indigenous broadleaved forest) and differing in proximity to Nelson’s urban/peri-urban areas. Wetlands and coastal areas were not included. To increase sample size and the diversity of surveyed habitats, three more transects were added during 2022; however, due to its remote location, one of these new transects was not surveyed again in 2023. Transect sites were selected to exemplify key habitats within Nelson reserves surrounding the Brook Waimārama Sanctuary, the South Island’s largest fully fenced, predator-free sanctuary for vulnerable native flora and fauna, and therefore a source of populations for eventual re-establishment of extirpated native species in the Nelson area. Individual transects are comprised of 6-to-13 point-count stations (adjacent stations located approximately 200m apart), the number of stations in each transect depending on the extent of the focal habitat.

方法步驟描述:

1. Point counts were made by a single observer during generally fine weather conditions with little wind, following standardised methods developed by the New Zealand Department of Conservation. Typically, four replicate point counts were conducted per counting station per year, on separate days sometime between late October to early December; however, due to poor weather, for three transects during three different years, only three counts were conducted. Throughout the entire nine-year monitoring period, each counting station was surveyed in total between 33 to 36 times, yielding data from 62-to-95 different counting stations annually and 235-to-369 individual point counts, depending on the number of transects visited, giving a grand total of 2,417 point counts during the nine-year monitoring period.
