Shei-Pa National Park's Wuling area has conducted nearly 20 years of stream ecology monitoring. In 2024, they first attempted to set up raptor perches along Qijiawan River, successfully recording Taiwan's largest owl—the Tawny Fish-owl.

The Tawny Fish-owl is a top predator in stream ecosystems, with prey including fish, amphibians, small mammals, and more, making it an important ecological indicator.

Since 2005, the Shei-Pa Headquarters have conducted long-term ecological monitoring of Qijiawan River, covering multiple aspects of stream ecology including water quality, physical habitat, frogs, fish, birds, and vegetation. This has not only positively benefited the conservation of the national treasure fish but also helped analyze the impact of climate change on stream ecology.

In 2024, the National Pingtung University of Science and Technology research team, through perches and automated cameras for long-term monitoring, captured the Tawny Fish-owl for the first time as it perched and hunted Formosan white-bellied rats. Additionally, they have repeatedly photographed Formosan serows, Reeves's muntjacs, wild boars, and other animals, demonstrating the conservation results accumulated through long-term ecological monitoring.
