Deforestation is a threat to forests according to foresters. Deforestation is the permanent destruction of forests and woodlands. Deforestation is brought about by commercial logging, conversion of woodlands to agricultural land, and the felling of trees for firewood and building material.
Commercial logging is that harvest of timber products for the profit that is gained from selling the product. Illegal logging is a threat to forests. Illegal logging is the harvest of timber for economic gain without permission. This method is a threat because it impedes plans and upkeep of a forest. Forests are lost to urban development and building projects. When forest are cleared for these reasons, it creates problems that foresters are concerned with. When heavy machinery is used to clear forests or develop land, the soil becomes compacted. When the soil is compacted, the soil particles are packed tightly together. Soil compaction results in water supply not being absorbed by tree roots and can be deadly to the growth of trees. Soil compaction also can create flooding. Compacted soil can not filter the groundwater into the soil, therefore water can build up on the surface creating flooding as a result.
Species extinction is another threat to our forests. With the removal of forests, animal and plant species suffer. Animal species can not survive without the adequate needs of their lifestyle. Animals need cover, food, and safe areas for the reproduction process. Altering their environment disrupts the life cycle of animal species and they are oftentimes not able to adapt. Food sources are lost to deforestation. Animal species tend to consume plant life to maintain themselves. With the removal of forests this can result in animals not being able to find food in order to survive.
Unmanaged recreational use is also a threat to forests. Unmanaged reacreational use is the use of the forested lands by the public at an uncontrolled rate. As recreational use as increased among forests, foresters have noticed an increase in land management that is needed. Invasive species threaten forests ecosystems. Invasive species are any species that is not native to that ecosystem and economic harm along with harm to the environment. Invasive species cause disruptions in the function of the ecosystem. These species not only affect the plants within a forest, but they can affect the animals within an ecosystem as well. The financial impact cause by invasive species is 138 billion dollars per year with economic loss and control costs.
