Our Story…

Ohia Ridge Farm is a 41-acre sustainable agricultural property at a 3300’ elevation on the slopes of Mauna Kea, located just below historic Umikoa Village and adjacent to the Hamakua Forest Reserve on the island of Hawaii. We are dedicated to diversifying the existing native montane forest and preserving habitat for rare plants and endangered birds. Your volunteerism supports the biodiversity of the native forest and to help develop a seed bank for the future expansion of Hawaii’s native forest.
