Helping preserve our native wildlife

Scientific Field Study

NZFM contributed to the NZ Falcon study undertaken by Dr Richard Seaton. The NZ Falcon study is particularly interesting to the forestry industry as it has been found that the falcon preferably inhabits forest clear-cut areas.

Mr Seaton visited Lake Taupo Forest and surveyed recently clearfelled areas within the forest to establish if any birds were nesting in the area. The results of the research will help NZFM to manage the forests to best protect NZ Falcons where they are present within the forest in the future.
