"At the particular area I had my cameras set up, logging had taken place just two years previously, and active logging was going on just a few kilometers away," Laila Bahaa-el-din, University of Kwazulu Natal graduate student, told mongabay.com at the time, adding that her findings "indicated that logging alone should not mean the depletion of wildlife."
In fact, a new policy paper in Conservation Letters agrees, making the case that logging in tropical forests could aid overall conservation efforts in the tropics by keeping a home for species like the African golden cat as well as safeguarding many ecosystem services. The authors assert that selective and well-managed logging should be considered a "middle way" between forest protection and outright destruction for monoculture plantations, agriculture, or livestock ranches.
"Selectively logged tropical forests, especially if they are logged gently and with care, retain most of their biodiversity and continue to provide ecosystem services such as carbon sequestration and hydrological functions," lead author Francis Putz with the University of Florida explained to mongabay.com, but he added that such forests are viewed very differently by many because "they lose the semblance of being untrammeled, pristine, virgin, or entirely natural."
Currently, over 400 million hectares (nearly a billion acres) of tropical forest is under timber production concessions, an area twice the size of Mexico.
Putz and his colleagues set out to discover how different a selectively logged forest was from a pristine one. Examining over 100-plus studies, they found that on average a forest that had been selectively logged once still retained 76 percent of its carbon and 85-100 percent of its biodiversity, with birds the most sensitive to one-time logging. For the researchers these findings implied once-logged and selectively logged forests should not be viewed as degraded, and thereby simply allowed to be cleared for plantations or agriculture. Instead well-managed timber concessions should be seen as conservation opportunities.

Of course, the researchers are aware that their study may be deemed controversial to many, and even anathema to some. They insist, however, that they are not advocating for increased logging in primary forests, but rather looking at the evidence for conservation potential in already-logged forests.
"Our study does not say that unlogged forest is equally valuable to pristine old-growth forest. They are different. All the authors will agree that we need to protect large areas of primary forest. Our point is that logged forests remain very valuable," Sheil says.
Putz adds that, "logging is going to happen anyway, so we should work to be sure that it is carried out in the most responsible ways possible. Secondly, logged forests retain vastly more of what I value than areas that have been converted into oil palm plantation, soybean fields, or cattle pastures."
Tropical biologist, William F. Laurance with James Cook University, recently co-wrote a paper warning of "peak timber" in the tropics—whereby loggers are cutting faster than forest can re-generate—however he says he generally agrees with Sheil and Putz's conclusions.
"A key priority right now is ensuing that logged forests aren't being cleared on a large scale. In this sense Jack Putz and his colleagues are quite correct in their arguments," Laurance told mongabay.com. "For instance, Indonesia has around 35 million hectares of selectively logged forest—a vast area the size of Germany—that is currently unprotected and subject to being cleared. This includes much of the country’s vulnerable lowlands forests, which are among the biologically richest on earth. It would be a great tragedy to lose these logged forests."
As Laurance points out, many conservationists have come to see conversion as a much more pressing and terrible threat to forests than logging, even a logging concession with little oversight.

Another recent study, also in Conservation Letters found that forests on the Indonesian island of Sumatra are as well protected in timber concessions as they are in conservation areas, such as a national parks, which often face illegal encroachment. According to the study, logging wasn't the primary threat in Sumatra, but large-scale conversion for plantations. The lead author of that study, David Gaveau, told mongabay.com that conservationists have begun to change their views on the perils of logging, at least in comparison to plantations, especially in Indonesia, where protected areas on paper are often not well protected in practice.
"Conservationists have depicted logging as 'evil' for several decades. In the 1980s, in Indonesia, conservationists were accusing logging companies of destroying Indonesia’s forests. That was before the advent of a bigger 'evil': forest conversion to industrial plantations, beginning in early 1990s," Gaveau says.
The current market poses a major problem for forests in general and logged forests in particular. Although scientists and policy-makers recognize that forests are vital for biodiversity, carbon sequestration, freshwater protection, erosion mitigation, and even rainfall production, it is still worth much more money in the short-term to clear a forest for commodities like palm oil or cattle, instead of protecting it. Even though in the long-term society must pay the bill for the ecological costs of climate change, biodiversity loss, and rainfall decline. Put simply, current markets don't value non-production forests, even though forests provide untold ecological benefits.
Given this Gaveau says environmentalists must be practical about their approach, if forests are to be preserved.
"Conservationists must propose conservation solutions that are economically attractive to make any progress. Logging concessions have the merit to address economic goals. Protected areas, on the other hand struggle to provide direct economic value. We are now slowly seeing a change in perception with increased understanding that logging concessions are an important component of maintaining those forests while promoting economic development."
But in many cases it is also worth more to clear a forest altogether than to set-up a well-managed selective logging concession.
"Unfortunately, numerous recent studies have shown that forest management for timber, even with substantial payments for carbon, falls far short of the profits from oil palm," says Putz. "Efforts to retain forest cover in areas where the Net Present Value (NPV) for oil palm or other intensive, non-forest use, are high, will most often not be successful."
In other words, for companies in developing nations the most attractive approach from a short-term economic perspective is often not protection or even logging, but outright conversion of the forest. This is one reason why scientists say there must be a truce between loggers and conservationists. Keeping logged forests as timber production forests is far preferable to what economics often demands: the total destruction of the forest.
Still not everyone is convinced that logging should play a major role in conservation efforts.
Simon Counsell, executive director of the Rainforest Foundation, says that research has shown that logging can have long-term and devastating impacts on tropical forests. Logging a forest can lead to fragmentation, which over time imperils biodiversity and makes the forest vulnerable.

In addition, says Counsell, allowing industrial logging "[reduces] the viability of alternative forms of sustainable management, such as community-based forestry."
Industrial logging may impoverish locals or indigenous people who have depended on the forest for generations, and locals are rarely given adequate information let alone compensation. According to Counsell, it would be better to set-up community programs than to continue to hand out vast forests to foreign companies.
Counsell also takes issue with some of Sheil and Putz's findings. For instance while logging may not diminish biodiversity immediately, it could have more insidious impacts over the long-term.
"There is reasonable evidence, not referred to specifically in this paper, that forest fragmentation typical in the logging-landscape context, can lead to long term species collapse," Counsell says, noting that there is little research so far on the long-term impacts of logging on biodiversity, in part because many of these forests are eventually cleared. "The jury remains out as to whether even 'well-managed' industrial logging concessions can even theoretically retain the original composition and diversity of wildlife."
He sees a similar problem when it comes to carbon sequestration. One year after the first-round of logging, three-fourths of the original carbon may still be present, he admits, but that carbon may not stay long.
"Studies have suggested that carbon losses continue long after the first pulse [of logging] due to removal of wood from the forest, and which can accelerate for a few years as logging debris starts to decompose, soils damaged by heavy logging equipment start to release stored carbon, and methane is generated from anaerobic decomposition of vegetation in streams and watercourses blocked by logging equipment and debris."
Counsell recommends that researchers look at the carbon impact over several decades after logging to see what is left and what has been emitted into the atmosphere.
For William Laurance, it's not the selective logging that is the biggest concern in forests, but the roads that bring in the loggers.
"Loggers bulldoze labyrinths of roads that open up forests to illegal colonists, farmers, miners, and hunters," he explains. "This can result in severe forest damage or outright forest destruction. That’s the real conundrum with logging—is it helping to save forests by providing an economic incentive for developing nations to retain and manage their forests, or is it just contributing to rapid forest loss? I don’t think there’s a simple answer."
But Sheil says that if an area is well-managed, roads would no longer be a major issue.

Hope, or at least clarity, may be found in well-managed timber operations—that is, if any exist in the tropics.
Why management matters
The defining characteristic in this debate may not be between who sees logging as an opportunity and who doesn't, but instead what is good forestry management? And are timber concessions in rainforests abiding by the best standards?
"To me 'well managed' means not only an extraction rate and cutting cycle that allows forest to persist and remain productive, but also a range of other practices that includes areas set-aside for conservation, buffers around streams and waterways, identification and protection of seed trees, avoidance of using machinery that will damage soils, prohibition of hunting, and long-term protection against conversion," says Sheil, who notes that "a well managed forest is often going to be better protected than an unmanaged primary forest."
But excluding a few timber concessions like Precious Woods' in Gabon, few, if any, logging companies in the tropics fits Sheil's demands.
"Just a few percent of all logged forests in the tropics," Laurance says should be considered low-impact logging.
But Counsell is even bleaker: "if 'well managed' were to be defined as something like 'fully compliant with the FSC's Principles and Criteria', then probably a very small fraction of one percent."

Putz and Sheil also agree that management has a long way to go in much of the tropics, but suggest in their paper that some improvements are already moving forward.
According to them, efforts to stop illegal logging could go a long way in improving forestry management in the tropics. In 2008 the U.S. amended its Lacey Act to prohibit the importation or sale of illegally logged wood. Meanwhile the EU has a similar measure in the Forest Law Enforcement, Governance, and Trade (FLEGT) initiative, and even stronger provisions coming into effect soon. Australia is also weighing new illegal logging legislation.
"[These] will serve to increase market prices and access for legally produced timber while promoting more responsible forest management," the researchers write. Illegal logging currently depresses the price of tropical timber by avoiding regulations and taxation.
The rise of independent certification can also be a force for good both by replacing lax government regulations and increasing prices for tropical wood, Putz and Sheil note. They add that certification measures should now work to reduce the cost for companies to undergo certification and include biodiversity and carbon monitoring in their work.
However, there remains considerable debate about the efficacy of such schemes. For example the world's leading forestry certifier, the Forest Stewardship Council (FSC), has been criticized by some for certifying clear-cutting and monoculture plantations, exactly what Putz and Sheil are trying to defend forests against. In addition, there have been occasions when FSC-certified companies have been in conflict with local communities. Despite such issues many of the world's leading conservation groups, including WWF and Greenpeace, continue to support the FSC as a means to mitigate the environmental impacts of forestry worldwide.
Perhaps more promising, if it can ever get off the ground, is REDD+, which stands for Reducing Emissions from Deforestation and Forest Degradation. This UN-developed program plans to build a fund that will pay tropical nations to keep from clearing their forests. Recent negotiations have also allowed carbon payments under REDD+ to be made to timber concessions, if their management is improved.
"Where REDD+ payments are used to improve rather than halt timber harvesting, the costs of maintaining forest cover are reduced relative to strict protection and there is less risk of activity-shifting leakage due to loggers going elsewhere to harvest timber," the researchers write. In addition, they say REDD+ could help build empower local communities.
Finally, Putz and Sheil argue that giving control of forests to indigenous groups and rural communities would likely result in significant improvements in forestry management.

In the end, these and other emerging trends could improve forest management across the tropics.
"Previous efforts to reform tropical forestry have had only limited success partially because they were not designed in ways that reflected the diversity of drivers of forest degradation and did not consider the perspectives of many important actors," Putz says. "Today, given the overlapping goals of interventions designed to reduce carbon emissions, to maintain other ecosystem services, to assure the legality of forest products, to capture the revenues due, to certify products from responsibly managed forests, and to devolve control over forests to local people, there are enormous shared co-benefits and efficiency increases to be derived from their synergies."
Still neither Sheil nor Putz are naive that broad efforts will be needed to succeed in management improvements across the tropics.
"We need to ensure that aiming at good management makes good business sense for forest based companies and government enterprises. We need incentives and regulations. We need government buy-in and support. We need training. We need awareness. We need to educate consumers and develop markets where the true costs of good management are covered," Sheil says, but he adds that, "we shouldn’t expect perfection and we actually don’t need it. Even moderately well managed forests maintain many values that we need to recognize and cherish."
The middle way?
Sheil and Putz say their paper outlines a "middle way" for conservation, a way that combines protected areas with logging concessions to sustain large forest landscapes, even if means giving up an idea of such landscapes as pristine.
"One conservation vision is to have large forested landscapes with strictly protected areas and well managed forests providing good habitats even for rare but wide ranging species. The alternative is the small fragments of strictly protected forests [which means] wide-ranging low density species will be lost. Which option do we prefer? I prefer the first if we can find a way to achieve it," Sheil says.
Counsell, however, sees the "middle way" as headed in the wrong direction.

But what about the jobs and economic output?
"Given the very limited benefits which tropical logging operations generate for state coffers, it would not be too expensive to pay a fair price to shut these operations down, compensating retrenched workers and generating alternative livelihoods for them," Counsell explains, adding that tropical forestry would not disappear altogether but change considerably. "Some tropical timber production can still be provided by smaller-scale community-based and small-medium enterprises where the use of heavy machinery is prohibited and as much value-added is generated within the forest itself—thus providing real benefits for local communities and incentives to sustain the forest in the long term."
For Counsell the key is to move overall control of tropical forests from governments and logging corporations to the local and indigenous people who live in and near the forests. Sheil and Putz approves a similar idea in their paper, but they see it as one solution among many and envision a different version than Counsell's. For them, partnerships between local owners and corporations would be the most fruitful.

"Any time you take a stance, especially on such unsure ground, there is a chance of misinterpretation, but denial of the compromise benefits or disregard of tropical forestry does not make much sense," Putz says.
"I don’t believe conservation science should censor itself when the implications are unpalatable or unpopular," Sheil says. "The anti-logging arguments have been very well articulated and seem widely recognized. Our concern is to look at the evidence available and ensure that these larger discussions and debate are informed by the most objective and accurate information."
One thing, however, is certain: time is running out for many of the world's rainforests, both logged and unlogged, as they fall to feed a global economy that doesn't yet value their services.

Forest activist shot dead in Cambodia allegedly over photos of illegal logging
(04/26/2012) Chut Wutty, a prominent activist against illegal logging and deforestation, has been killed in the Koh Kong province of Cambodia. Wutty was shot dead at a military police checkpoint while traveling with two journalists with The Cambodia Daily. The journalists are currently being held for questioning by the military police.
U.S. gobbling illegal wood from Peru's Amazon rainforest
(04/10/2012) The next time you buy wood, you may want to make sure it's not from Peru. According to an in-depth new report by the Environmental Investigation Agency (EIA), the illegal logging trade is booming in the Peruvian Amazon and much of the wood is being exported to the U.S. Following the labyrinthian trail of illegal logging from the devastated forests of the Peruvian Amazon to the warehouses of the U.S., the EIA identified over 112 shipments of illegally logged cedar and big-leaf mahogany between January 2008 and May 2010. In fact, the group found that over a third (35 percent) of all the shipments of cedar and mahogany from Peru to the U.S. were from illegal sources, a percentage that is likely conservative.
Fight illegal logging by going after criminal masterminds
(03/22/2012) Illegal logging has never been a high priority for criminal investigators, but a new report by the World Bank says it should be. Worldwide, the illegal logging epidemic is decimating natural resources, imperiling biodiversity, emitting carbon, and undercutting the livelihoods of local and indigenous people. But the lucrative funds from these ill-gotten gains is just as problematic: top organized criminals rake in $10-15 billion annually from illegal logging and largely use the funds to drive corruption.
Deforestation increases in the Congo rainforest
(03/20/2012) Deforestation in the Congo Basin has increased sharply since the 1990s, reports an extensive new assessment of forests in the six-nation region. Released by the Central African Forests Commission (COMIFAC) and members of the Congo Basin Forest Partnership, The State of the Forest finds that the region's annual gross deforestation rate doubled from 0.13 percent to 0.26 percent between the 1990s and the 2000-2005 period. Gross degradation caused by logging, fire, and other impacts increased from 0.07 percent to 0.14 percent on an annual basis. Despite the jump, rates in the Congo Basin remain well below those in Latin America and Southeast Asia, but the region is seen as a prime target for future agroindustrial expansion.
Investigation links APP to illegal logging of protected trees
(03/01/2012) A year-long undercover investigation has found evidence of Asia Pulp and Paper (APP) companies cutting and pulping legally protected ramin trees, a practice that violates both Indonesian and international law. Found largely in Sumatra's peatswamp forests, the logging of ramin trees (in the genus Gonystylus) has been banned in Indonesia since 2001; the trees are also listed under Appendix II of the Convention on International Trade in Endangered Species (CITES) and thus require special permits to export. The new allegations come after APP, an umbrella paper brand, has lost several customers due to its continued reliance on pulp from rainforest and peatland forests in Sumatra.
Big trees, like the old-growth forests they inhabit, are declining globally
(01/26/2012) Already on the decline worldwide, big trees face a dire future due to habitat fragmentation, selective harvesting by loggers, exotic invaders, and the effects of climate change, warns an article published this week in New Scientist magazine. Reviewing research from forests around the world, William F. Laurance, an ecologist at James Cook University in Cairns, Australia, provides evidence of decline among the world's 'biggest and most magnificent' trees and details the range of threats they face. He says their demise will have substantial impacts on biodiversity and forest ecology, while worsening climate change.
Logging of primary rainforests not ecologically sustainable, argue scientists
(01/25/2012) Tropical countries may face a risk of 'peak timber' as continued logging of rainforests exceeds the capacity of forests to regenerate timber stocks and substantially increases the risk of outright clearing for agricultural and industrial plantations, argues a trio of scientists writing in the journal Biological Conservation. The implications for climate, biodiversity, and local economies are substantial.
Old-growth forests are irreplaceable for sustaining biodiversity
(09/14/2011) Old growth rainforests should be a top conservation priority when it comes to protecting wildlife, reports a new comprehensive assessment published in the journal Nature. The research examined 138 scientific studies across 28 tropical countries. It found consistently that biodiversity level were substantially lower in disturbed forests.
Logged rainforests are a cheap conservation option
(09/14/2011) With old-growth forests fast diminishing and land prices surging across Southeast Asia due to rising returns from timber and agricultural commodities, opportunities to save some of the region's rarest species seem to be dwindling. But a new paper, published in the journal Conservation Letters, highlights an often overlooked opportunity for conservation: selectively logged forests.
Indonesia's moratorium undermines community forestry in favor of industrial interests
(06/21/2011) Indonesia's moratorium on new concessions in primary forest areas and peatlands "completely ignores" the existence of community forestry management licenses, jeopardizing efforts to improve the sustainability of Indonesia's forest sector and ensure benefits from forest use reach local people, say environmentalists. According to Greenomics-Indonesia, a Jakarta-based NGO, community and village forestry licenses are not among the many exemptions spelled under the presidential instruction that defines the moratorium. The instruction, issued last month, grants exemptions for industrial developers and allows business-as-usual in secondary forest areas by the pulp and paper, mining and palm oil industries.
Loss of old growth forest continues
(10/06/2010) A new global assessment of forest stocks by the U.N. Food and Agriculture Organization (FAO) shows continuing loss of primary forests since 2005 despite gains in the extent of protected areas. FAO's Global Forest Resources Assessment 2010 reveals some 13 million hectares of forest were cleared between 2000 and 2010, down from around 16 million hectares per year during the 1990s. Loss of primary forest—mostly a consequence of logging—averaged 4.2 million hectares per year, down from 4.7 million hectares per year in the 1990s.
Timber certification is not enough to save rainforests
(06/02/2010) In the 1980s and 1990s pressure from activist groups led some of the world's largest forestry products companies and retailers to join forces with environmentalists to form the Forest Stewardship Council (FSC), a certification standard that aims to reduce the environmental impact of wood and paper production on natural forests. Despite initial skepticism on whether buyers would pay a premium for greener forest products, FSC quickly grew and by 2000 had become a standard in many markets, including Europe and the United States. Companies like Home Depot, Lowe's, and Ikea are today strong supporters of the FSC. But the FSC has not been without controversy. In recent years some activists have voiced concern about FSC standards as well as the credibility of auditors that certify timber operations. Among the initiative's supporters is the Rainforest Action Network (RAN), a group best known for its aggressive protest tactics. RAN says engagement with the FSC is better than the alternative: leaving the timber industry to devise its own sustainability standards.
Destruction of old-growth forests looms over climate talks
(12/08/2009) Destruction of old-growth or primary forests looms large in discussions in Copenhagen over a scheme to compensate tropical countries for reducing emissions from deforestation and degradation (REDD). Some environmental groups are pressing for conservation of old-growth forests — the most carbon-dense, and biologically-rich state of forests — to be the centerpiece of REDD, while industry and other actors are pushing for "sustainable forest management" or logging using reduced-impact techniques to be the primary focus of REDD.
Rainforest conversion to oil palm causes 83% of wildlife to disappear
(09/15/2008) Conversion of primary rainforest to an oil palm plantation results in a loss of more than 80 percent of species, reports a new comprehensive review of the impacts of growing palm oil production. The research is published in the journal Trends in Ecology and Evolution.
In the Amazon, primary forest biodiversity tops that of secondary forest, plantations
(11/12/2007) Plantations and secondary forests are no match for primary Amazon rainforest in terms of biodiversity, reports the largest ever assessment of the biodiversity conservation value in the tropics.
