With its close proximity to the greater Taipei metropolitan area, Yangmingshan National Park is tasked with many burdens associated with supporting recreational activities. Abandoned animals have been found in the Park, including dogs, cats, Formosan macaques, red-eared slider turtles, red swamp crawfish, and many others. Some of the animals are invasive species which could jeopardize the survival of native species. They threaten not only the natural food chain, but can also carry infectious diseases, posing a threat to the safety of visitors. 

The problem of stray dogs has become especially serious. With the increasing number of recreational activities at the Park, an equal increase has been noted in the number of cases of stray dogs being released, abandoned, or improperly fed, which threatens the safety of visitors at the Park's various scenic spots. In addition to continuing to monitor invasive species, the Headquarters also notifies the Taipei City Animal Protection Office and the New Taipei City Government Office of Animal Protection and Health Inspection for removal. 

In nature, wild animals have their own natural instincts when foraging and feeding, forming an intricate food chain （network）. Improper feeding could change the feeding habits of animals and cause dependence on humans for sustenance, threatening the balance of local ecology and visitor safety and even cause environmental pollution. For this reason, the Park Headquarters strongly urges visitors to never abandon or release pets or feed any wild animals （especially stray dogs, Formosan macaques, and squirrels） in the Park. Protecting the beautiful mountains and forests which surround Taipei is everyone's responsibility. By working together, we can all continue to enjoy access to the beauty and natural ecology of Yangmingshan National Park.
