Westland Petrels and their Influence on Forest Ecology and Biodiversity – Dr David Hawke
10 April at 7:00 pm - 9:00 pm
Petrels and shearwaters were abundant in the forested hill country of pre-human New Zealand, and they very likely contributed greatly to nutrient fluxes and ecology. Westland petrels are the only substantive remnant, and so give us a good window on the past. However, like other forested ecosystems, the Westland petrel system been subject to predatory and browsing mammals and biodiversity loss.
In this talk, Dr David Hawke will look at what the Westland petrel system can tell us, and bring in information from other New Zealand systems to try and fill in the gaps. For the most part, he will focus on the information that stable isotopes of carbon and nitrogen can provide.
David’s talk will be preceded by a 15-min presentation by Roland Eveleens who won a North Canterbury Forest and Bird Stocker Scholarship.
Supper and a chat afterwards.
