LOGGING
Logging is one of the most prominent and best-known forms of rainforest degradation and destruction. Despite improved logging techniques and greater international awareness and concern for the rainforests, unsustainable logging of tropical rainforests continues—much of it practiced illegally by criminal syndicates.
In the late 1990s, after depleting much of their own timber stocks, Asian logging companies began aggressively moving into rainforest areas including northeastern South America (Guyana, Suriname); the Brazilian Amazon; the Congo Basin of Central Africa; the South Pacific, particularly the Solomon Islands and Papua New Guinea; and Central America. Chinese timber firms have been particularly active of late, after the government banned domestic logging in much of the country following catastrophic flooding in 1998. With a construction boom fueling demand for wood, China has recently been linked to logging in Africa, the Amazon, Burma, and Indonesia.
Typical logging operations are quite damaging to the rainforest ecosystem. Problems stem from the nature of limited-term timber concessions, which encourage short-term resource depletion, and poor forest planning and management. Corruption is rife in many tropical timber-producing countries, making existing forestry laws nearly unenforceable, while lack of transparency in commercial transactions means that corrupt officials can grant concessions to cronies without regard for the environment or consideration of local people. The structure of the rainforest itself—where no one species dominates and attractive timber trees are widely dispersed—means that it can simply be more profitable to clear- cut forest. Even without clear-cutting, the construction of logging roads to reach forest resources is destructive in the its own right and encourages settlement of previously inaccessible forest lands by speculators, land developers, and poor farmers. Studies by the Environmental Defense Fund show that areas that have been selectively logged are eight times more likely to be settled and cleared by shifting cultivators than untouched rainforests because of the access granted by logging roads. Research has found a high correlation between the presence of logging roads and consumption of "bushmeat"—wild animals hunted as food.
Logging roads aside, selective logging itself—where only one or two valuable tree species are harvested from an area—can take a heavy toll on primary tropical forests. A late 2005 study conducted by scientists from the Carnegie Institution at Stanford University determined that "selective logging" creates twice as much damage as is detected by satellites while resulting in 25 percent more greenhouse gas emissions than previously believed.
Selective logging—as usually practiced—is degrading to the forest because the felling of a single large tree can bring down dozens of surrounding trees which are connected to the target tree by vines and lianas. The thinning of the protective canopy exposes the forest to increased sunlight and drying winds that can kill symbiotic soil organisms essential for decomposition and nutrient-fixing, while drying leaf litter and increasing the forest's vulnerability to fire. Further, the use of tractors for removing trees tears up the soil and increases erosion. Selective logging has been found to reduce global biodiversity by destroying habitat for primary forest species.
These tropical logging operations widely fail to safeguard timber stocks for future harvests and fail to protect logged-over forest from fire, biodiversity loss, over-hunting, and subsequent conversion for agriculture or pasture. But the damage caused by clear-cutters is even worse. Operators who do not practice selective logging may instead simply burn a forest tract after valuable trees have been removed.

An Account of Illegal Logging in Thailand
Poor economics
Developing countries often see only a fraction of the money they deserve from legal logging operations, and even less from illegal logging, which, according to World Bank estimates, costs governments about US$5 billion in lost revenues annually and hits national economies for another US$10 billion per year. Logging firms can often find or create loopholes in legislation that allow them to pay very little for concessions while sometimes avoiding excise taxes on the logs they remove. For example, a 1994 logging agreement in Suriname granted 25 percent of Suriname's land area (7.5 million acres or 3 million hectares) at less than $35 an acre, while lacking provisions to safeguard the environment, reforest logged areas, or even allow the country to adequately monitor logging activities. Estimates at the time from the U.S. Forestry Service and Harvard Law School project that while loggers would earn some US$28 million annually, the country will only see US$2 million. Meanwhile, in the late 1990s, the Cambodian government was losing so much revenue from its failure to collect taxes on timber that the IMF canceled a $120 million loan and the World Bank suspended direct aid to the government until the corruption in the forestry sector was resolved. Apparently these actions were not enough to stem forest loss: between 2000 and 2005, Cambodia lost nearly 30 percent of its primary forest cover. In Nigeria, which suffered the highest rate of primary forest loss (55.7 percent) in the first half of this decade, WEMPCO, a Hong Kong logging firm, reportedly paid US$28 to the government for each mahogany tree while reselling the wood at US$800 per cubic meter, roughly US$2,900 per tree.
Tropical Hardwood Log Imports into Japan
Total Tropical Timber Imports into Japan Tropical countries also lose potential revenue by exporting logs before processing, when wood has its lowest value. Several countries, including Cambodia, the Solomon Islands, and Burma, have banned raw log exports in an effort to increase revenue for local operators and the government, but raw logs are commonly smuggled by crime syndicates.
"Sustainable logging"
Sustainable forestry is possible, but according to the International Tropical Timber Organization, less than 1 percent of logging in the tropics is truly sustainable. In a recent survey none of 34 sites in the Para state of Brazil had met ITTO harvesting requirements that Brazil had agreed to implement by the year 2000. Several techniques like strip logging and reduced impact logging (See Ch 10: Solutions: "sustainable logging") show potential, but do little good if they are not adopted.
Rainforest logging operations are also particularly subject to "greenwash" where a firm claims to be committed to sustainable harvesting techniques but in practice is failing to implement the most basic safeguards.
Review questions:
- Why can selective logging be destructive in the rainforest?
- What is the hunting of wild animals for food called?
- What is greenwash?

Some toilet paper production destroys Indonesian rainforests, endangering tigers and elephants
(02/09/2012) American consumers are unwittingly contributing to the destruction of endangered rainforests in Sumatra by purchasing certain brands of toilet paper, asserts a new report published by the environmental group WWF. The report, Don't Flush Tiger Forests: Toilet Paper, U.S. Supermarkets, and the Destruction of Indonesia's Last Tiger Habitats, takes aim at two tissue brands that source fiber from Asia Pulp & Paper (APP), a paper products giant long criticized by environmentalists and scientists for its forestry practices on the Indonesian island of Sumatra. The brands — Paseo and Livi — are among the fastest growing, in terms of sales, in the United States.
Tropical ecologist: Australia must follow U.S. and EU in banning illegally logged wood
(02/09/2012) Australia should join the widening effort to stamp out illegal logging, according to testimony given this week by tropical ecologist William Laurance with James Cook University. Presenting before the Australian Senate's rural affairs committee, Laurance argued that the massive environmental and economic costs of illegal logging worldwide should press Australia to tighten regulations against importing illegally logged timber at home.
Green groups: government moving too slowly on protecting Canada's Great Bear rainforest
(02/08/2012) Three environmental groups have submitted a letter to British Columbia Premier, Christy Clark, to ask the government to speed up the process of implementing the Great Bear Rainforest Agreement, which is meant to ensure 70 percent of old-growth forest is maintained.
Caution urged in sale of Madagascar's illegal timber stockpiles
(02/03/2012) Confiscated timber stocks in Madagascar must be managed in a "transparent manner" to deter future illegal logging and boosting demand for endangered rainforest timber, says a letter published by a coalition of NGOs.
Indonesia to require loggers prove their concessions free of overlapping claims
(02/02/2012) Applicants for forest concessions in Indonesia will soon be required to prove there aren't overlapping claims on their holdings, reports The Jakarta Globe. The move, which offers the potential to reduce land disputes between forest developers and local communities, could complicate investments in the forestry sector in Indonesia.
