An interview with Jim and Jean Thomas of the Tenkile Conservation Alliance

On the brink of extinction in 2001 with a population estimated at fewer than 100 individuals, Scott's Tree Kangaroo (Dendrolagus scottae), or the tenkile, is recovering, thanks to the efforts of the Tenkile Conservation Alliance to motivate local communities to reduce hunting and respect critical forest habitat. The tenkile Conservation Alliance, led by Australians Jim and Jean Thomas, works to provide alternative sources of protein and raise environmental awareness among local communities.

In the face of these challenges, the Tenkile Conservation Alliance (TCA) is taking a multifaceted approach to ensure that local people benefit from conservation. Education programs to ensure that villagers understand the impact of unrestrained hunting and forest clearing have led to a moratorium on hunting of the tenkile, while turning the species into a local source of pride.

TCA's project is also providing food security for local communities by introducing alternate sources of protein—rabbits and chickens—thereby reducing hunting pressure on wildlife. The group hopes to soon capitalize on a proposed climate change mitigation mechanism known as REDD (Reducing Emissions from Deforestation and Degradation) to generate funds for conservation areas as well as local communities.
"The benefits the people need to manage their resources under a carbon trading venture are roads for transporting cash crops to market, permanent housing and solar power," the Thomases said. "This is basically what we are competing against with logging because logging companies promise roads, housing, and power."
The Thomases are hopeful that REDD could generate sufficient funds to enable villages to legally withdraw from logging in Forest Management Areas, thereby protecting these areas for wildlife and sustainable use by people.
The Thomases discussed TCA's efforts to save the tenkile during an August interview with mongabay.com.

Mongabay: What is your background and how did you become interested in tree kangaroos?
Jim and Jean Thomas: Both Jean and I studied at LaTrobe and Melbourne Universities, although at different times. We met when we both worked for Zoos Victoria on the native mammal section with tree kangraoos.

In 1998 Zoos Victoria and Rainforest Habitat - PNG formed a partnership after a workshop about the plight of Tree Kangaroos. This PHVA (Population and Habitat Viability Analysis) workshop concluded that Tenkile would become extinct within 10 years without outside assistance. A hunting moratorium for Tenkile was established in 1999 and the Tenkile Conservation Alliance (TCA) was established as an NGO (non-government organization) in 2001. We started in early 2003 and have pretty much run and managed TCA since then.
Mongabay: Is the tenkile naturally rare or has it declined from a once-large population?
Jim and Jean Thomas: The Tenkile has only been recorded from the Torricelli and Bewani Mountains of the North Coast ranges of New Guinea. It once had a greater distribution but has been reduced by 70-80 percent by hunting and a trebling of the human population within the last 50 years.
Mongabay: Is overhunting the result of population growth from cultural change in local communities?
 On the 10th of June an adult male Tenkile was released back into the wild. It was held in captivity for a month to monitor its defecation rate. The results will assist TCA's distance sampling research. |
Mongabay: Is there much logging in the area? If so, do you see the potential for payments for ecosystem services as a means to deliver economic benefits to local people?
Jim and Jean Thomas: There is a lot of logging going on around us. Some of our villages have recently reported illegal logging on their land. There are also oil palm projects and a planned slurry pipe for a mining company. So, the three most environmentally damaging lines of work surround the Torricelli Mountain Range. We are aiming to conduct carbon trading and are working with other bodies developing projects. We are confident that, should the required funding be available, we can increase our project area to include Forest Management Areas (FMA), having those villages legally withdraw from logging. The benefits the people need to manage their resources under a carbon trading venture are roads for transporting cash crops to market, permanent housing and solar power. This is basically what we are competing against with logging because logging companies promise roads, housing and power.
Mongabay: How do villagers respond to your efforts? Do you have an difficulties convincing people to care about animals they rely upon for food?
Jim and Jean Thomas:

Mongabay: Are there any opportunities for rehabilitation of animals captured as food? Are tenkile ever kept locally as pets?
Jim and Jean Thomas: At TCA Base-Lumi we pretty much have a mini zoo. if an orphaned animal comes to us we generally look after it. Sometimes we can save animals, sometimes we can't. We presently have 6 Grizzled Tree Kangaroos, 2 Weimangs, 1 NG Pademelon, 2 Cuscus, 8 Sugar Gliders, 3 Ground Boas, 2 New Guinea freshwater turtles, 1 NG freshwater crocodile, 1 Flying Fox, a Western Black-capped Lori and a Victoria Crowned Pigeon.
Generally people only keep dogs, pigs and chickens as pets. When wildlife is caught and then caged in the village it generally doesn't survive long.
Mongabay: Are there ways to boost the population through ex-situ measures?
 Aini - from Wuguble village. TCA has provided each village with a 1000 gallon Tuffa Tank. Water tanks were seen as a necessity by TCA staff to better improve the rabbit farming project and assist local communities with a clean water supply that was close to the village.Water is normally collected from local water sources that are not necessarily clean and disease free. Many people suffer from diarrhea and other water borne diseases in the area so clean water supplies are essential in any village. Water is normally collected by women and carried to the village in bamboo water carriers or saucepans and buckets. In some villages, women have to walk for more than 30 minutes to collect water with some having to walk up hill and in rugged terrain. By reducing the workload of women, this has helped give them time to rest and assist the rabbit project. TCA had a local plumber provide water tank training to two female representatives from each village. This enabled women to realize how to maintain the water tank and prevent damage occurring. |
Mongabay: Are you working with other species beyond the tenkile?
Jim and Jean Thomas: The Tenkile and the Weimang are the flagship species. TCA aims to conduct more studies on other species when funding becomes available.
Mongabay: What are the biggest challenges of working in the field?
Jim and Jean Thomas: The biggest challenges in the field are the remoteness, the steep slopes of the Torricelli's and the amount of rain. Here in Lumi we receive up to 3.5 meters per year.
Mongabay: Is there any potential for tourism to help?
Jim and Jean Thomas: TCA would like to see tourism get a chance in the Torricelli's. There is real potential here and we are educating the people about what is needed to conduct eco-tourism. There is a lot we need to do before inviting tourists to the area such as infrastructure and footpaths to the villages and mountains.
Mongabay: How can people in places like the U.S. help your efforts?

Mongabay: Do you have any tips for aspiring field conservationists?
Jim and Jean Thomas: Anyone doing real, on the ground conservation must be willing to spend long periods of time away from family and friends. They must be willing to face many disappointments to start with and perhaps not have their first "win" for six months or more. The world needs more people working in remote areas of wilderness in developing countries doing conservation, education and trying to protect rainforests. Rainforests are the most delicate and vulnerable ecosystems in the world and serve as the lungs of the planet.
