Mahogany Industry Essay

Abstract Brazilian mahogany industry has been damaged by attacks from the shoot borer Hypsipyla grandella (Lepidoptera: Pyralidae), and the main injury is caused by the larvae, which destroy the terminal shoots. In an attempt to avoid such consequences in the future, the Brazilian industry has evaluated replacing the cultivars of Swietenia macrophilla with trees from the Khaya ivorensis and K. anthotheca (Brazilian and African mahogany, respectively). Thus, some species of African Khaya were introduced in Brazil and they showed excellent growth and absence of attacks by H. grandella. However, recently canker disease has become one of the most important problems in K. ivorensis trees. Koch’s postulate data reported herein showed that mahogany cankers …show more content…

The Brazilian mahoganies are trees of the genus Swietenia (Meliaceae) (Silva et al. 2008). Between 1980 and 1984, Brazilian mahogany accounted for more than 30 percent of the volume of timber exported throughout Brazil. In a response to the perceived threat of extinction, the Brazilian government has adopted a series of regulatory actions beginning in the early 1990s. As a starting point, timber extraction in Brazil has to be certified by the federal government through the Brazilian Institute for the Environment and Renewable Natural Resources (IBAMA). In addition, an annual export quota was determined to help protect the stock of mahogany in the forest. Export quotas were reduced to 65,000 m3 in 1998, and then 30,000 m3 in 2001. The following year, a presidential decree established a two-year moratorium on the authorization of new management plans. This decree was subsequently renewed in the following years (http://www.mma.gov.br). The Brazilian timber industry has been seriously damaged by attacks from the shoot borer Hypsipyla grandella (Lepidoptera: Pyralidae) (Maia et al. 2000). The host range of this oligophagous pantropical species is limited principally to the

  • Kennesaw State Arboretum: Difference Between Age And Size Of Wood Trees

    704 Words  | 3 Pages

    The Kennesaw State Arboretum is spilt from an upslope and a downslope which was examined to seeing the difference in age and size of the hardwood and pine trees. The variation of age and size can be due to changes in the progressive changes in the tree species over time. This was tested by measuring pine and hardwood trees in 2 different areas of the forest, upslope and downslope, collecting tree data with at least 25cm circumference and 10 ft. tall in 5 different plots of 100 m2. The data describes the hypothesis that if the upslope and downslope parts of the forest differ in age, then the size of the eldest hardwood trees of the upslope and downslope will differ. If the upslope and downslope parts of the forest are different ages, then the forest will differ in proportion of mature hardwood relative to pine.

  • The Causes Of Deforestation In The Brazilian Amazon

    933 Words  | 4 Pages

    The Brazilian Amazon is home to 40% of the world’s tropical rainforest. Incidentally, it also has the world’s fastest rate of deforestation. Tropical Rainforests around the world are lost at the rate of one acre per second with the average rate of Brazilian Amazon being such that 2 million hectares of forest land are cleared every year. There are multiple causes for this extensive rate of deforestation and this paper will address four such causes namely (1) rapid population growth, (2) industrial logging and mining, (3) changing spatial patterns of deforestation, and (4) wildfires. Moreover, there are several Brazilian state policies that encourage deforestation practices of which this paper will look at five key aspects – (1) taxes on agricultural income, (2) rules of land allocation, (3) land taxes, and (4) tax credit schemes and subsidized credits.

Forest provides habitats for more than half of the fauna and flora on the Earth (SCBD, 2001). Forest biome plays an important role in mitigating climate change by serving as carbon sinks (Hassan et al., 2005). Forest land is the most fundamental natural resources which become reduced mainly due to anthropogenic pressures.
