An example is the Kuantu Nature Park, run by the Taipei City Wild Bird Society. Bird lovers have been running it by their best efforts for 20 years, but in recent times, with the successive threats of SARS and bird flu, the number of visitors has slumped, and the park has accumulated losses of several million NT dollars.
以台北市野鳥學會經營的關渡自然公園為例，鳥界人士勉力經營 20 年，但近年陸續受 SARS、禽流感疫情波及，參觀人數驟減，已經虧損了數百萬元。
