Interdisciplinary research on a change in conservation policy meaning endangered species can be observed without disturbance

Research grant

Project Description

Investigating the compatibility of species conservation and tourism as the habitat of Blakiston's fish owl opens to the public.
As the Blakiston's fish owl is an endangered species, there have been prevention methods to stop the intrusion of people into nesting sites, and Japan habitat information has remained private. However, there are accommodation facilities available which are attracting customers such as photography inclined birdwatchers, or visitors who want to feed the owls. The aim of this research was to look at ways conservation and tourism could coexist, with the Blakiston's fish owl as the main focus. Based on the above premise that it is impossible to hide the habitat of this creature, a way to view the animal without having a negative effect on the population continuance of endangered species is needed.
