Abundance and diversity of herbaceous weeds in sheep/beef pastures, South Island, New Zealand
This study compared species diversity, abundance and size of broad-leaved herbaceous weeds on 28 South Island sheep/beef farms that employed either organic, integrated management (IM) or conventional management (CM) systems. ...
Reduction of bias when estimating bird abundance within small habitat fragments
We used the distance detection function from five-minute point counts entirely within large woody vegetation patches to derive a method of truncating counts of birds detected close to the observer to estimate their relative ...
Local people see and care most? Severe depletion of inshore fisheries and its consequences for Māori communities in New Zealand
Overfishing has the potential to adversely affect the ecological stability, economic value, social and spiritual integrity of a given area. Of these contexts, relatively little emphasis in literature is placed on the social ...
Rakiura Māori muttonbirding diaries: monitoring trends in tītī (Puffinus griseus) abundance in New Zealand
Rakiura Māori seek robust population monitoring to guide sustainable management of the annual take of muttonbird (tītī, Puffinus griseus), in southern New Zealand. Analyses of eight muttonbirder harvest records spanning ...
Detection probability for estimating bird density on New Zealand sheep & beef farms
Factors influencing detection probability in line transect distance sampling were investigated to estimate the abundance of four common farmland birds on 12 sheep & beef farms in the South Island of New Zealand. Our primary ...
Enhancing our heritage: Conservation for 21st Century New Zealanders: Ways forward from the Tahi group of concerned scientists
New Zealanders are constantly reminded of their degraded environment and the threatened status of their unique plants, animals and ecosystems. Instead of presenting these as symptoms of unsustainable living and the ...
Listening to the Kaitiaki: consequences of the loss of abundance and biodiversity of coastal ecosystems in Aotearoa New Zealand
Interviews with 22 kaitiaki (environmental guardians) from 14 tribes spread throughout the North Island of New Zealand revealed a common concern that the abundance and diversity of sea foods have declined along much of the ...
Age at First Return to the Breeding Colony and Juvenile Survival of Sooty Shearwaters
Using mark-recapture, we estimated the age at first return and survival of juveniles of the Sooty Shearwater (Puffinus griseus), a medium-sized burrow-breeding procellariiform, at two New Zealand breeding colonies, Taiaroa ...
Drivers of Seabird Population Recovery on New Zealand Islands after Predator Eradication
Eradication of introduced mammalian predators from islands has become increasingly common, with over 800 successful projects around the world. Historically, introduced predators extirpated or reduced the size of many seabird ...
Modeling Harvest Intensity of Sooty Shearwater Chicks by Rakiura Māori in New Zealand
Cultural evidence suggests that sooty shearwater (Puffinus griseus) chicks have been harvested by Rakiura Māori on islands in southern New Zealand since prehistoric times. Concerns exist that modern harvests may be impacting ...
