Tina Hydropower Limited (THL) was established by Korea Water Resources Corporation (K-water) and Hyundai Engineering Corporation Limited (HEC). THL will Build, Own, Operate and Transfer (BOOT) the Project under an Implementation Agreement (IA) and a Power Purchase Agreement (PPA) with the Solomon Islands Government (SIG) and Solomon Islands Electricity Authority, respectively. The BOOT concession is expected to last for a 30-year period, following commissioning. HEC will be responsible for the Engineering, Procurement and Construction (EPC) of the Project, while THL will be responsible for the Operation and Maintenance contract. THL will sell electricity to the Solomon Islands Electricity Authority (SIEA) trading as Solomon Power, the state-owned power utility, for the duration of the concession. At the end of the concession, the hydropower infrastructure will be transferred to the SIG or SIEA. This Biodiversity Management Plan (BMP; P2), is part of a suite of environmental and social management plans (ESMPs) that have been prepared for the Tina River Hydropower Development Project (the Project). An Environmental and Social Impact Assessment (ESIA) for the TRHDP was completed in 2017, with a revision in 2019. The ESIA includes requirements for a set of plans to guide implementation of the various phases of the project, including a Construction ESMP (CESMP; P1). One of the plans required to be developed in the preparation phase is the BMP (this plan). The purpose of the BMP is to outline actions and methods required to avoid, minimise, mitigate, and offset potential impacts of TRHDP activities on biodiversity. To ensure the project leads to the conservation or enhancement of biodiversity outcomes, the scope of the BMP is focused on the Tina River Catchment as a whole, and encompasses all biological areas that have the potential to be directly and indirectly impacted by the project. The geographical extent of Tina River catchment and key elements of the project disturbance (namely the Direct Impact Area) that will be included within the scope of the BMP are shown in Figure 1-1.

  • The Solomon Islands

    The Solomon Islands

    THE SOLOMON ISLANDS 14 SEPTEMBER – 7 OCTOBER 2007 TOUR REPORT LEADER: MARK VAN BEIRS Rain, mud, sweat, steep mountains, shy, skulky birds, shaky logistics and an airline with a dubious reputation, that is what the Solomon Islands tour is all about, but these forgotten islands in the southwest Pacific also hold some very rarely observed birds that very few birders will ever have the privilege to add to their lifelist. Birdquest’s fourth tour to the Solomons went without a hiccup. Solomon Airlines did a great job and never let us down, it rained regularly and we cursed quite a bit on the steep mountain trails, but the birds were out of this world. We birded the islands of Guadalcanal, Rennell, Gizo and Malaita by road, cruised into Ranongga and Vella Lavella by boat, and trekked up into the mountains of Kolombangara, Makira and Santa Isabel. The bird of the tour was the incredible and truly bizarre Solomon Islands Frogmouth that posed so very, very well for us. The fantastic series of endemics ranged from Solomon Sea Eagles, through the many pigeons and doves - including scope views of the very rare Yellow-legged Pigeon and the bizarre Crested Cuckoo- Dove - and parrots, from cockatoos to pygmy parrots, to a biogeographer’s dream array of myzomelas, monarchs and white-eyes. A total of 146 species were seen (and another 5 heard) and included most of the available endemics, but we also enjoyed a close insight into the lifestyle and culture of this traditional Pacific country, and into the complex geography of the beautiful forests and islet-studded reefs.

    Muruk July 2007 Vol 8-3-1

    Editorial There has been a 7-year gap between the last issue of the Papua New Guinea Birdwatching Society’s journal Muruk in 2000 (Vol. 8: 2) and this issue, which completes that volume. It serves a valuable purpose documenting significant records of New Guinea birds, and publishing notes and papers relevant to New Guinea ornithology. Thanks are due to Conservation International’s Melanesia Centre for Biodiversity Conservation (funded by the Gordon and Betty Moore Foundation) for coming up with funds for the printing of the journal, with particular thanks to Roger James. The idea is to clear a large backlog of records, and publish articles relating to New Guinea ornithology, with the help of an editorial team: Editor - Phil Gregory Editorial consultants: K. David Bishop, Ian Burrows, Brian Coates, Guy Dutson, Chris Eastwood. We would like feedback about the direction the journal should take; it has been a useful reference resource over the years and is cited in many publications. Current thinking is to publish two issues per annum, with thoughts about expanding coverage to include other nearby areas such as Halmahera and the Solomon Islands, which have a large New Guinea component to the avifauna. The Pacific region as a whole is poorly served and there may be scope to include other parts of Melanesia and Polynesia. We now complete the old pre-2000 subscriptions with this issue, which is sent free to former subscribers, and invite new subscriptions. Editorial address: PO Box 387, Kuranda, Queensland 4881, Australia. Email - [email protected] Significant Sightings from Tour Reports Compiled and edited by Phil Gregory More and more companies are offering tours to PNG, mostly doing the same circuit but still coming up with interesting records or little known or rare species, breeding data or distributional information.

    Birding Melanesia 2015 Report by Adam Walleyn

    Melanesia Discover and Secrets of Melanesia: Birding Melanesia 2015 Report By Adam Walleyn Cardinal Lory pair. Copyright Adrian Hayward The 2015 Melanesian Birding trip was another great success. The year will probably long be remembered for one of the worst droughts ever and while the dry and windy conditions made birding more difficult than usual, we persevered and ended up with an incredible tally of endemics, many of them amongst the most poorly known birds in the world! This incredible itinerary takes in part of the north coast of Papua New Guinea and all of the main islands of the Bismarcks, Solomons and Vanuatu, along with many of the smaller ones. This region is one of the world’s most avian endemic-rich hotspots and is largely inaccessible and unvisited by birders. Amongst 267 species, highlights this year included Superb Pitta sitting right in the open, an unexpected Manus Fantail, one of the first observations of Mussau Triller, a stunning Solomons Nightjar, and incredible diversity of fruit doves (12 species), imperial pigeons (12 species), myzomelas (11 species) and of course white-eyes (10 species). The trip started off with a nice dinner in Madang and then our first of many early mornings to bird a patch of forest not far from town. Bird activity was great this morning and there were a number of fruiting trees which allowed good views of two species of birds of paradise - Lesser Bird of Paradise and Glossy-mantled Manucode. Other nice birds in the fruiting trees included Orange-bellied and Pink-spotted Fruit Dove, Zoe’s Imperial Pigeon, Orange-breasted Fig Parrot, and numerous Golden Myna.

    Secrets of Melanesia With Chris Leahy And in Partnership with Rockjumper Birding Tours th st 20 to 31 October 2017 (12 days) Claret-breasted Fruit Doves by Jonathan Rossouw This voyage takes us into a world that few have ever experienced, including visiting idyllic islands and isolated villages where unique time-honoured traditions and elaborately costumed dancers welcome us into their special world. Commencing in Honiara, the capital of the Solomon Islands, we set sail to discover the beauty of the outer Solomon Islands. Here we can relax as our ship glides into secluded bays, and takes us to remote oceanic islands where the ancient art of traditional navigation survives even until today. In Vanuatu, we have the opportunity to search for several endemic bird species, or else to dive and explore one of the planet’s most famous wrecks and discover hidden underwater worlds bejewelled with a dazzling array of astounding marine life. For birders, this itinerary offers once-in-a-lifetime species on remote islands where very few people have been before. The birding potential is exceptional, and we offer an optional specialised Massachusetts Audubon Secrets of Melanesia 2 birding programme with customised excursions to maximise our birding opportunities of the region’s numerous endemic and range-restricted species. In addition, these waters provide some of the greatest diving in the world, and there will be various opportunities for everybody to snorkel and appreciate the beauty beneath the waves, as well as an optional scuba-diving programme

Mud, sweat, extended slippery treks, steep mountains, shaky logistics, and constant battles with land access. This is what a Solomon Islands tour is all about, but these sleepy forgotten islands in the southwest Pacific hold some glorious, very rarely observed birds that very few birders will ever have the privilege to add to their lifelist. The Solomon Islands comprise Endemic Bird Areas 198 and 199, and although the total area of this archipelago is smaller than Belgium (less than 50,000 km2), these rich islands have more restricted range species than any other Endemic Bird Area in the world! Of the Solomons EBA endemics, we amazingly recorded all 70 of the likely species on this route, plus an additional clean sweep of the 13 available Melanesian endemics - hitting 100% of our key targets in this demanding country is certainly a miracle, and surely rates this as our most successful tour yet! Of these specials, just two were heard only, so we were all very pleased indeed. We had fantastic looks at four genera that are endemic to the Solomon Islands: Rigidipenna (Solomons Frogmouth), Nesoclopeus (Woodford’s Rail), Meliarchus (Makira Honeyeater) and Woodfordia (Bare-eyed White-eye), plus enjoyed the easternmost members of two highly desirable families (the cute Solomons Cockatoo and the glorious Black-faced Pitta).

  • The Solomon Islands

    The wonderfully bizarre Solomons Frogmouth was the ‘Bird of the Trip’ (Josh Bergmark) THE SOLOMON ISLANDS 6 JULY – 1 AUGUST 2017 LEADER: MARK VAN BEIRS and JOSH BERGMARK 1 BirdQuest Tour Report: The Solomon Islands www.birdquest-tours.com Magnificent, but often skulking birds. Mud, sweat, slippery trails, steep mountains, shaky logistics, and an airline with a dubious reputation. This is what the Solomon Islands tour is all about, but these forgotten islands in the southwest Pacific hold some glorious, very rarely observed birds that very few birders will ever have the privilege to add to their lifelist. Our tour total this year included a great selection and a large percentage of the endemic birds and specialities. The Solomon Islands comprise Endemic Bird Areas 198 and 199, and although the total area of this archipelago is smaller than Belgium (less than 50,000 km2), these rich islands have more restricted range species than any other Endemic Bird Area in the world! Of the Solomons EBA endemics, we recorded 64 of the 68 possible species on this route, plus an additional clean sweep of the 13 available Melanesian endemics. We had good looks at three genera that are endemic to the Solomon Islands: Rigidipenna (Solomons Frogmouth), Meliarchus (Makira Honeyeater) and Woodfordia (Bare-eyed White-eye). This tour is definitely one of our toughest trips through a combination of intense physical effort, unpredictable weather and capricious logistics. The treacherous paths of the Makira hills, the tough hike and overnight high on Kolombangara volcano and the sometimes brutally steep, slippery trails of Santa Isabel will long be remembered by all participants.
