Description

This palm is the stoutest of all Balaka growing to a height of 4-7 m with a trunk up to 10cm in diameter. It is also distinguished by the unique twists of 40o-60 o in the rachilla (inflorescence stem) with the sections between the twists otherwise straight. This is a character not observed in other Balaka species. The trunk is green but turns grey with age; the nodes are conspicuous, light green-brown in colour. The crown comprises 8-10 fronds that can reach up to 3 m in length, they are held erect, with regular quite closely spaced leaflets which are mid green in colour; the crown shaft is green-light brown. The inflorescence emerges between the leaves in young palms and beneath the crown shaft as they get older. The inflorescence is branched to three orders with the characteristic twists described above. The fruit are orange-red at maturity, averaging 22 mm long and 11 mm wide in size.

Distribution

Balaka streptostachys is known only from a single population in Vanua Levu on the northern foothills of Mt Sorolevu.

Habitat Ecology and Behaviour

This palm is an understorey palm in the wet, lower montane forest from which the sole population is known. This is a small restricted site above the Matani Creek where the rainfall is over 3000 mm of rain a year. Other than observations on its location and description of the palm, no other research into its ecology, habitat requirements and even into searching for more populations have been conducted.

Threats

The only known population of this palm comprises about 50 adult trees, although a thorough search of the surrounding area has yet to be made. This small population is vulnerable to the on-going logging activities in the general area and the reported plans for conversion to mahogany plantation could mean the extinction of this palm at its only known location.

Conservation Status

This is a critically endangered palm, and, there are currently no measures to protect it in the sole location where it is currently known.

Remarks and Cultural Significance

This is a critically endangered palm, and, there are currently no measures to protect it in the sole location where it is currently known.

Taveuni National Park Project
Located in the Province of Cakaudrove, the island of Taveuni is Fijiís 3rd largest island. Since the 1980s, the National Trust and the Fiji Department of Forests have been advocating for the merger of the Ravilevu Nature Reserve, Taveuni Forest Reserve and the Bouma National Heritage Park to form the Taveuni National Park. In 1993 the Fiji Department of Environment proposed the ĎIntegrated Development Plan for Taveunií supporting this combination to better promote the wilderness and cultural features of Taveuni to harness Taveuniís tourism market to its full potential. The Fiji Department of Forests, National Protected Areas Committee, Cakaudrove Provincial Council and NatureFiji-MareqetiViti, with support from the Critical Ecosystems Partnership Fund are revitalising efforts to bring Taveuni's three current protected areas into one Taveuni National Park: 1. Taveuni Forest Reserve (FR). Declared in 1914. Size: 11, 160 HA 2. Ravilevu Nature Reserve (NR). Declared in 1959. Size: 4, 108 HA 3. Bouma National Heritage Park (BNHP). Established by covenant in 1990. 1, 417 HA. TAVEUNIíS WILDLIFE AND LANDSCAPE Much of Fijiís land and forest has now been impacted and modified by deforestation, commercial and subsistence agriculture, plantation timber production and/or invasive alien species. We must also remember the historic impacts of the first human settlement that resulted, for example, in the extinction of many species and conversion of dry forests to grasslands. Not only has Taveuni retained significant forest and wetland ecosystems across a full altitudinal range (ridge to reef), but also it has not been severely impacted by invasive species, in particular the mongoose. The absence of the mongoose from Fijiís third largest island has resulted in the retention not only of Taveuniís endemic fauna species but also Fijian endemics that have been extirpated or are highly threatened on Viti Levu and Vanua Levu. SPECIAL LANDSCAPES ON TAVEUNI Taveuniís outstanding landscape qualities are derived mainly from its tropical forest cover. From all points around the Taveuni coastline, there are views of the undisturbed, densely forested uplands. Frequently cloud and mist-capped, the rugged central range dominates the landscape with characteristic emergent volcanic cones. From the peaks of the central range descend the long symmetry of old lava flows covered with dense rainforest. Taveuni is one of the very few islands where the scale of negative land use impacts has been limited. But current trends of widespread soil degradation and encroachment into the reserves indeicate taht this is changing for the worse. The thriving agricultural industry of Taveuni can attribute its success to the Taveuni Forest Reserve which was established to ensure unlimited water supply and free ecosystem services to the people of Taveuni. While the Taveuni FR currently provides little monetary benefit to landowners, combined with the Ravilevu NR and Bouma National Heritage Park, the Taveuni National Park will build a strong imperative for ecotourism development. THE PROJECT Not until 2009 were landowners informed about plans which had been around for 30 years on possible Protected Areas development, and the potential of Taveuni's forests for conservation. If there is one conspicuous lesson of the lead up work of the Sovi Basin Protected Area project, it was that there was no real progress until the landowners and the Fijian administration took up ownership of the process. Getting the landowners involved in the PA discussions is the main objective of this project.
