HO’OMAU RANCH CONSERVANCY is a non-profit 501(c)(3) organization promoting and assisting in the reforestation, restoration and conservation of native Hawai’ian Forest lands and species.We are preparing to plant in the 265 acre and 65 acre fenced HO’OMAU RANCH forested areas which host a healthy habitat for plants and animals including critically endangered species such as the Mehamehame, largest of the native tree species and Loulu Palm (Prichardia Schatteuer). These areas host healthy old growth Ohia and are also home to the endangered Hawaiian hawk. Hawaiian tiny snails, the Kamehameha butterfly and many native birds including apapane, iiwi, elepaio and amakihi also make these areas their home………….safe in many ways through the zero tolerance ungulate fencing!We gratefully accept your DONATIONS to assist in this work.LOVE alone can’t get the job done!
Land and Resource Description
The HO’OMAU RANCH property is divided into two portions by the separately owned 1926 lava flow, which supports pristine, early successional native vegetation. To the north and to the south of this flow, the landscape of the region is a mosaic of variously older pieces of lava flow, mostly ‘a’a, that support variously older plant communities. The ranch’s lava flows support a mosaic of different forest types, some orchards and both productive and degraded pasture types. The oldest lava flows are found south of the 1926 flow, and support excellent pastures and contiguously about 235 ac of very rare (last patch known) mesic ohi’a-olopua-aulu native forest.
The varied geological setting, of both the larger region and the ranch within, is further complicated by the presence of two rainfall gradients. The steeper gradient tracks the elevation gradient, wettest near the mauka end of the ranch. A gentler rainfall gradient runs from south to north, with Manuka, Kaulanamauna and Kapua ahupua’a to the south being a bit drier than HO’OMAU RANCH. These drier ahupua’a tend to have different plant communities than the more mesic and wetter vegetation types. The drier ahupua’a have also suffered protracted droughts in recent decades, as evidenced by large-scale mortality of ohi’a, the major canopy tree. HO’OMAU RANCH has been fortunate not to have been so negatively affected.
HO’OMAU RANCH occupies a central portion of a large region of South Kona that is set aside as South Kona Forest Reserve (several sections), two Natural Area Reserves, the extensive Kona Hema Preserve, Hawaii Volcanoes National Park and other areas of remaining native vegetation with no designation. Collectively, they retain enough biodiversity to ensure that the native ecosystems found within can still function, despite some species losses. In a volcanically active region, having a large area with much ecological variability is essential in order to maintain the region’s ability to rebuild and replace losses that normally occur from lava flow coverage. Each lava flow continues to acquire additional species to its communities as it ages until it is covered by a new flow. The additional species additions come from kipuka of the oldest flows, refuges for plants and animals requiring more mature conditions. These act as dispersal centers for species to move out and colonize the larger region. Having variability, redundancy and a large area are all key elements in keeping the regional ecology functioning in such a dynamic volcanic landscape. Ho’omau Ranch contains some of the key native elements not found much or at all elsewhere.

NATIVE ANIMAL LIFE
This draft plan has focused on plants and vegetation because they are the foundation of ecosystems. The next draft will have a much greater discussion of the endemic ope’epe’a (bat), and the birds (amakihi, apapane, ‘elepaio, ‘io, pueo, ua’u and indigenous ‘ake’ake) that reside or fly over HO’OMAU RANCH. The Monarch butterfly, the Kamehameha butterfly and the “tiny snail” also habitat Ho’omau. Some are rare or endangered, and may require detailed consideration. Four of the preceding animals feed on native insects and other arthropods, which form the bulk of the native biodiversity in native ecosystems. Given the close association that has evolved between native arthropods and native plants, a primary strategy will be to promote the diversity of native plants in the land cover at the ranch.
NATIVE HAWAIIAN FOREST
HO’OMAU RANCH is home to ten of the twelve known adult individuals of Loulu Palm Pritchardia Schattaueri remaining in the wild. They are the tallest species of the genus reaching the height of 96-128 feet. HO’OMAU RANCH includes the range of the age and the quality found within the larger regional matrix. This complex matrix defines the range of opportunities and influences the problems at Ho’omau and within the region in general. A few areas contain critically rare native species and a structurally sound mixed mesic forest. Overall, HO’OMAU RANCH has generally wetter conditions than are seen to the south, and generally drier than is seen on state forest reserve lands to the north. These characteristics make parts of Ho’omau ideally suited for local rare plant protection, habitat restoration and self propagation of both rare and uncommon plants within an existing forest structure.
