Taiwan Island's Xiaoliuqiu Implements Nightly Road Closures to Protect Critically Endangered Land Crabs

Measures aim to safeguard migrating land crabs during mating season and enhance ecological tourism, with local support for conservation efforts.

Efforts are underway in Taiwan's Xiaoliuqiu to protect its unique land crab population. The Dapeng Bay National Scenic Area Headquarters is proposing nightly closures of Meiren Road from May 1st to September 30th each year. This initiative is designed to prevent the significant loss of land crabs due to vehicle collisions during their vital migration to the sea for mating and egg-laying.

The land crab migration, which occurs annually between May and October, has tragically led to a substantial number of casualties. Recent reports indicate that nearly 1,200 land crabs have been killed since late April. Conservation volunteers have identified Meiren Road, along with sections of Huandao Road near Sunset Pavilion and Wild Boar Ditch, as critical hotspots for these unfortunate incidents.

A representative from the headquarters, Chen Jung-feng (陳榮豐), confirmed the plan to close Meiren Road nightly during the migration period, effectively transforming it into a pedestrian-only zone. This proposal is currently awaiting approval from the Pingtung County Government. The headquarters also plans to engage with local tour guides to inform them about these upcoming changes, aiming to ensure a smooth transition and foster collaboration in conservation efforts.

Local conservation volunteers have expressed strong support for the proposed road closures, viewing them as a crucial step forward. One volunteer, who preferred to remain anonymous, highlighted the decline in land crab sightings during nighttime ecological tours, despite existing efforts to mitigate roadkill. The volunteer noted that during the egg-laying season, an average of a dozen crabs are run over daily, with weekend figures escalating to over one hundred.

The volunteer emphasized that the consistent closure of these roads will not only create a safer environment for the land crabs but also significantly improve the experience for both tourists and residents exploring Meiren Road. The absence of vehicular traffic is expected to enhance the overall atmosphere and allow for better observation of the island's natural wonders.

In addition to road closures, the headquarters announced in May an expansion of conservation measures. These include the installation of new signage and stickers to raise public awareness about the land crabs' plight. Furthermore, proposals are in place to modify smooth surfaces on retaining walls and coastal fences, making them more accessible for crabs to navigate as they make their way to the sea.

Concerns over the declining land crab population have been mounting. Volunteers reported a drastic drop in sightings in 2024, estimating them to be only 20% of the previous year's levels. The high mortality rate, with over 1,000 crabs lost between early June and mid-July of last year, has prompted calls for stronger governmental action. Professor Chiu Yuh-wen (邱郁文) of National Chiayi University has urged authorities to implement concrete measures to ensure the long-term survival of the island's unique land crab population.
