observation records of urban forests use

We performed visitor observations to collect data on use intensity and activity. The observation were carried out during Aug-Oct 2016 in the 20 selected urban forest patches. The survey was conducted only on sunny or partly cloudy days. Observations were performed for at least 90 min during the busiest visiting time: on weekdays after working hours (16:00-18:00) and on weekends during the daytime. We counted the forest visitors, including their gender, age class, and activities. Age classes were estimated and classified into junior (under 18 years old), young adult (18-44), adult (45-64) and senior (over 65). Activities were categorized into cycling, walking, dog walking, Nordic walking (pole walking), playing with kids, picking berries or mushrooms, etc.
