Taijiang National Park's Luermen Dream Lake and its surrounding coastal forest are a hot spot habitat for Taiwan's largest brown land crab. To protect the land crabs when they migrate to the sea to release larvae from June to November, the Taijiang National Park Headquarters implements traffic control on the Qingcaolun Embankment flood control road (an approximately 2-kilometer section).

This year (2026), three phases of traffic control are planned, with the times from July 1-July 5, July 30-August 3, and August 29-September 2, from 18:30 to 21:30 daily. Motor vehicles are prohibited from entering during the control period, and the public is advised against traveling there unless necessary; if walking in is required, please park vehicles at the former Super Water Park’s parking lot and abide by the pedestrian control regulations.

In addition to traffic control, the Taijiang National Park Headquarters also arrange for volunteers to conduct surveys and patrols, and collaborates with the Seventh Special Police Corps, NPA to protect them together. The public is advised to cooperate with traffic control during the land crab breeding season and avoid related coastal roads, leaving the right of way to mother land crabs, working together to contribute a share of effort to ecological conservation, and ensuring that the land crabs can successfully complete the breeding mission of migrating to the sea to release larvae.
