Specifically, we assessed how the specificity (overlap between fern and ground-dwelling ants) and the benefits of this interaction are altered by selective logging and conversion to an oil palm plantation habitat. This process allows for better yield and productivity over several decades. Some authors, most notably Dawkins (1958), went so far as to suggest that selective harvesting of moist tropical forest might be incompatible with the goal of sustained-yield management because of the excessive damage to residual vegetation that resulted from mechanized logging. Also, leaving trees standing keeps the forest looking natural while contributing to reduced runoff of delicate topsoil and the minimizing of silting of nearby streams and rivers. A study by a Brazilian commission showed that 80% of all logging in the Amazon was illegal during the late 90s 2. "Most forestry practices are not necessarily bad for wildlife." (McEvoy, 2012 .

While laws exist which authorize logging in designated areas, illegal logging is widespread in Brazil and several Amazon countries. The "Selective Logging" made sense. It creates a more natural-looking forest stand after harvesting. Additionally, selective logging is less impactful than forest fires. The importance of damage in the course of logging has been illustrated in the literature. Harvesting under the selective logging system has also unintentionally allowed overcutting in the natural forests. By contrast, selective logging of tropical forests is often regarded as having a lesser impact on the ecosystem particularly in long terms, even though there have been few critical evaluations of the practice, particularly in . Every year, selective logging in the Brazilian Amazon clears an area of rainforest equivalent to the size of Connecticut.

During the 1980s, logging on Borneo led to Malaysia becoming the largest exporter of tropical wood. "While it is true that many species are adversely affected by selective logging and some are entirely unable to survive in disturbed forest, a large number of species are able to maintain viable populations." (Johns, 1985, p. 355). Answer: Given the chance, people will always exploit the natural environment around them. Disadvantages: Selective logging can harm the trees surrounding the ones being targeted which can be more disastrous than normal logging as it can cause diseases through the trees.
