Effectiveness of New Zealand Falcon (Falco novaeseelandiae) presence in Marlborough vineyards for bird control - objective measurement and identification of obstacles to adoption by the industry : A dissertation submitted in partial fulfilment of the requirements for the Degree of Bachelor of Science with Honours at Lincoln University

Abstract

This research aims to evaluate the effectiveness of the New Zealand falcon project. This was done in two parts. The first part used grape damage surveys to assess how effective they were at controlling bird damage. Secondly, an objective survey of the Marlborough viticulture industry was completed to identify any obstacles to adoption by the industry. The results of the grape damage surveys indicate a significant reduction in grape damage for all varieties measured (Pinot noir, Pinot gris and Sauvignon blanc). Significant relationships were found between distance from falcon feeding platforms and the presence and extent (percent) of damage. There was also a significant difference found between damage in Sauvignon blanc and Pinot gris. The survey of the viticulture industry identified clear obstacles to the adoption of this new initiative. These obstacles include a lack of knowledge regarding the project, the cost involved in the project and the lack of clear leadership. Recommendations were made based upon these results as to how these obstacles could be overcome.
