Araucaria biramulata, the biramule araucaria, or piggyback araucaria, is a species of conifer in the family Araucariaceae. It is found only in New Caledonia on the main island of Grande Terre. Araucaria biramulata is a medium-large tree reaching 30 meters in height.[1] As with several other endemic New Caledonian araucaria species, it is threatened by habitat loss with a fragmented wild population of less than 10,000 mature trees, and ongoing decline in remaining populations, with the main threats being forest fires and mining activities.[2] Piggyback araucaria gets its common name from the unusual growth habit of mature trees, where they often develop a second growth tip halfway up the trunk, giving the appearance of a smaller tree "piggybacking" on the side of a larger one.[3]
