Project Description

For Blakiston's Fish-owl, an endangered species, birdwatchers and photographers who enter its habitat, come excessively close and use strobe photography are having the greatest negative effect on the conservation of the species. This research aims to bring these facts to light and create a way of observing endangered species without harmful effects through examining the regulatory methods that are possible under current laws, and as necessary, propose specific revisions to existing laws.
