Holua camping area closed Thursday

The Holua cabin and camping area in Haleakala Crater will be closed Thursday due to work to control the non-native Argentine ants, the National Park Service said.

Argentine ants prey on native insects. The endemic yellow-faced bee, the primary pollinator of the threatened ahinahina, or silversword, is among those insects that are highly vulnerable to the ant.

Holua is located near the bottom of the Halemauu Trail switchbacks, one of the major access trails to the crater. Park control efforts are focusing on Holua to prevent accidental human spreading of the ant to uninfested areas of the crater.

The Holua backcountry camping area will reopen in the afternoon of June 21. All other backcountry trails, cabins and the Paliku camping area will remain open and will not be affected by this closure.
