Are those pine trees that we see around the Arboretum and all over Manoa Valley?

This family is only found in the Southern Hemisphere, wheras the Pine Family ("Pinaceae") is restricted to the Northern Hemisphere. The most common Araucarias in manoa valley are the Cook "Pines" (Araucaria columnaris) which are native to New Caledonia, the Loyalty Islands, and the Isle of Pines. This is the most common Araucaria grown in the state of Hawai'i, and is often mistaken for the Norfolk Island "Pine" (Araucaria heterophylla).

Gingers and some other tropical plants in the Tacca and Maranta families, typically go dormant for a period of six months, roughly from October to April, which is our rainy season.
We hear chainsaws and see fallen trees. Why are trees being removed?
The Arboretum cares for the forest by removing declining, dead, or fallen trees as part of its responsibility of tending to this living museum. Tree removals are also necessary to get rid of weedy trees which compete with more desirable trees in our garden.
