The United Nations Environment Programme (UNEP), one of the key organizations behind the report, believes that targeting scarce conservation funds on these 15 key countries may pay dividends in terms of environmental results.
Importantly, the survey also reveals that the pressure from people and population growth on most of these remaining closed forests, such as those in Bolivia and Peru, is low.
Others, such as the remaining closed forests in India and China, are under more pressure from human activity and may require a bigger effort to conserve and protect, the report concludes.
But overall an estimated 88 per cent of these vital forests are sparsely populated, which give well-focused and well-funded conservation efforts a real chance of success.
The findings have come from scientists with UNEP working with other researchers including ones from the United States Geological Survey and NASA, the United States space agency.
Klaus Toepfer, Executive Director of UNEP, says:" The importance of healthy forests cannot be underestimated. Forests are vital for the well being of the planet. They provide a variety of socio-economic and ecological goods and services. These include watershed management, with forests regulating the quantity and quality of rainwater discharging into rivers. They also help counter soil erosion and the spread of deserts.
"They play a vital role in reducing the impacts of climate change by soaking up carbon from the air. Forests also harbour some of the world's most precious and endangered wildlife, provide food and medicines for many local communities and indigenous peoples across the globe and support eco-tourism, which can be economically important, especially in developing countries," he adds.
But despite their important role and numerous international conferences, conventions and agreements including the Forestry Principles, drawn up during the Earth Summit in 1992, and the Convention on Biological Diversity, forests around the globe remain under increasing threat.
"Short of a miraculous transformation in the attitude of people and governments, the Earth's remaining closed-canopy forests and their associated biodiversity are destined to disappear in the coming decades. Knowing it is unlikely that all forests can be protected, it would be better to focus conservation priorities on those target areas that have the best prospects for continued existence. I believe this new study provides this new focus. I urge governments, communities and international organizations to act on our findings and recommendations," he says.
The report, which the authors claim is the most comprehensive and reliable assessment ever made of global forest cover, has used satellite-based information to identify the extent and distribution of the World's Remaining Closed Forests (WRCF).
These are defined as forests with a canopy closure of more than 40 per cent. Such a level of canopy closure is considered vital if the forest is to be considered healthy and able to perform all its known environmental and ecological functions effectively. Such forests are also home to some of the world's rarest and most unique species including the elusive cloud leopard of Russia and the lion-tailed macaque of the Western Ghats in India.
Ashbindu Singh, Regional Coordinator at UNEP's Division of Early Warning and Assesment, says: "We have found that 80.6 per cent of the WRCF are located in 15 countries. These are Russia, Canada, Brazil, the United States of America, Democractic Republic of the Congo, China, Indonesia, Mexico, Peru, Colombia, Bolivia, Venezuela, India, Australia and Papua New Guinea. Four are in industrialized countries and 11 are in the developing world".
Population pressures, one of the key threats to the world's remaining forests, vary between the countries. But overall 88 per cent of the world's remaining closed forests in these key 15 countries have low if non-existent population densities.
Mr Singh says high population pressures in closed forests areas can be seen in India and China. In India, 43 per cent of closed forests have high population densities. In China 36 per cent are facing high population densities whereas almost all closed forest areas in Peru and Bolivia are free from high population pressure.
Other countries free from high population pressures and with significant closed forests include the Democratic Republic of the Congo, Papua New Guinea, Brazil, Russia and Canada.
The report, An Assessment of the Status of the World's Remaining Closed Forests(see For More Information on details of how to download the report), argues that it is vital to act now to protect these last important forests: "The low population densities in and around the majority of the WRCF areas offer an excellent opportunity for conservation, if appropriate steps are taken now by the national governments and the international community. The cornerstone of future policies for the protection of WRCF should be based on protection, education and alternatives to forest exploitation".
It shows that remaining closed forests in Venezuela enjoy the highest level of official protection with 63 per cent in protected areas. This is followed by Bolivia, 30 per cent; Colombia, 25 per cent and Indonesia, 20 per cent.
Among the 15 key countries identified in the report, Russia has the lowest level of protection with just two per cent protected followed by Mexico, three per cent; China, 3.6 per cent, the United States, 6.7 per cent and Canada, 7.4 per cent.
The report has also found that 53 countries have more than 30 per cent of their land cover under closed forests. Some of those, especially ones with low population densities, could also eventually be the focus of vigorous conservation efforts after the forests of the first 15 countries have been made secure.
Candidates for this second wave of action might include Gabon and the Republic of the Congo in Africa; Belize in Central America and French Guiana, Guyana and Suriname in South America.
The report calls on governments in the key 15 countries concerned to draft action plans detailing how they propose to conserve their remaining closed forests. The level of protected areas also need to be sharply increased backed by tougher policing of such sites alongside crackdowns on smuggling and poaching of trees and wildlife.
Better communications for and training of park staff are needed as well as tighter national conservation laws.
The report also calls for road and dam construction to be subject to "rigorous scrutiny" and the conversion of forest land to be allowed only after exhausting other alternatives.
Wealthy countries should invest in the protection of the last remaining closed forests situated in poorer countries. The investment required is likely to be modest.
Debt-for-Nature Swaps, in which developing country debts are reduced by industrialized countries in return for closed forest protection, should be vigorously encouraged, the report says.
UNEP, for its part, is working through its recently launched Great Apes Survival Project (GRASP), as one way of helping the world's remaining closed forests. UNEP is to establish conservation projects in forests across Africa and Indonesia to help save the Gorilla, Chimpanzee, Bonobo and Orangutan.
The projects focus on issues such as ecotourism and forest protection, supporting staff in national parks, educating local people about the importance of great apes and encouraging alternatives to exploiting the animals for food.
UNEP is also soon to publish a Strategy on Global Forest Assessment and Monitoring which will outline other actions the organization will be taking in support of forest conservation. These will include developing its monitoring and assessment of closed forests in partnership with governments, space agencies, non-governmental organizations and the Food and Agricultural Organization of the United Nations. It hopes to create a permanent forest monitoring system.
The strategy is also likely to lead to a new assessment of the impacts of population growth, economic expansion and climate change on forests, and by implication, human beings.
