"This bridge and road would imperil some of the most important wildlife habitats remaining in West Kalimantan. Given that there are clearly viable alternatives to the bridge project that are far less harmful, it’d be utterly illogical for it to proceed," said William Laurance, one of the world's foremost tropical conservationists and scientists. Laurance is currently a Distinguished Research Professor at James Cook University.

However, warns the ATBC resolution, all of this could be lost if developers cut a road along the forest's edge, allowing people easier entry to its riches: "uncontrolled access to [the Sungai Wain forest] will almost certainly result in a major increase in settlements, farming, illegal logging, and land speculation that will threaten native habitats and lead to increased fires and wildlife poaching."
As important as the area is for biodiversity, it is equally important for local people. The Sungai Wain forest provides one of the region's only undiminished watersheds used for in local industry, while "the bay itself includes a variety of freshwater, brackish, and mangrove habitats that provide vital breeding areas for commercially important fish and crustacean species that help to sustain local fisheries," according to the resolution.
ATBC endorses an alternate route that would avoid the mangrove stands and the Sungai Wain forest altogether and have less impact on the bay. Local officials have also come forward in favor of this route given that it is significantly shorter (80 kilometers) than the current one.
The resolution "urges the Federal Government of Indonesia and the Provincial Government of East Kalimantan to join with local authorities to support" the alternate route.
The island of Borneo has lost nearly 50 percent of its forest cover since the 1970s, an impact that has been felt in Kalimantan—the largest area of Borneo—as much as any other region on the island. This staggering loss of forests has jeopardized the future of innumerable species; produced vast greenhouse gas emissions; and diminished important 'ecosystem services', such as clean water, pollination, food and fish production.
"Most coastal and estuarine ecosystems of East Kalimantan have been devastated, and so it’s vital to protect the few ecologically viable areas that remain," Laurance says.

Scientists commend Indonesia for conservation measures, but urge immediate action on forests and peatlands
(07/23/2010) Scientists convening at the annual Association for Tropical Biology and Conservation (ATBC) meeting in Sanur, Bali urged Indonesia's leaders to strengthen measures to protect the country's biologically-rich ecosystems. In a resolution issued on the final day of the five-day conference, ATBC commended Indonesia for recent moves to protect forests, including a pledge to cut illegal logging and a billion dollar partnership with Norway to reduce deforestation and forest degradation, but asked the government to immediately implement a planned moratorium on new forestry concessions on peatlands and primary forest lands.
Indonesia's forests are a global heritage, says VP
(07/21/2010) The vice president of Indonesia on Wednesday urged scientists and the broader international community to help Indonesia find a balance between conservation and natural resource use.
Bridge development in Kalimantan threatens rainforest, mangroves, and coral reef
(01/03/2010) Balikpapan Bay in East Kalimantan is home to an incredible variety of ecosystems: in the shallow bay waters endangered dugong feed on sea grasses and salt water crocodiles sleep; along the bay proboscis monkeys leap among mangroves thirty meters tall and Irrawaddy dolphins roam; beyond the mangroves lies the Sungai Wain Protection forest; here, the Sunda clouded leopard hunts, sun bears climb into the canopy searching for fruits and nuts, and a reintroduced population of orangutans makes their nests; but this wilderness, along with all of its myriad inhabitants, is threatened by a plan to build a bridge and road connecting the towns of Penajam and Balikpapan.
