Nowadays, the use of unmanned aerial vehicles (UAV), also known as drones, has been common for professionals and amateurs. And UAVs play an important role in imaging and mapping in the area of landscape architecture. Researchers have proved that using UAVs to observe people is more reliable compared to traditional ways. All the park users' features including ages, genders, activities, etc. can be recognized by the equipped camera. However, the overpowerful machine also created panic among people. Increasing people started to worry that their privacy would all gone after they realized the power of drones, especially when they at public open space where is exposed to the sky. The panic would have a psychological negative influence on people's intention to the park and then impair the value of open public space. Trees can effectively block the visual access from the sky and provide people the sense of protection. Appropriate use of trees can create landscapes that people feel secure from drones. This paper will use Sarah P. Duke Garden as the site to test the relationship between the tree density and the human sense of secure. And develop some landscape design ideas for the garden to reduce the visual accessibility which could be scenarios to apply to any other places.
