Camp Blaz last week announced that the last mature håyun lågu has died, more than a year after major damage from Typhoon Mawar. But while the Ritidian mother tree died, protection of the young trees that originated from it continues, the statement from Camp Blaz added.

"This left the tree exposed to powerful and destructive wind from typhoons that were bound to come," the groups said in their statement. Håyun lågu is a tree species found only on Guam and Rota.

“The loss of this mother tree is a clear sign of the devastation that the U.S. military has wrought on the Native people and species of Guam,” said Maxx Phillips, attorney and Pacific Islands director for the Center for Biological Diversity.
