What is the human impact on coniferous forests?
Solution
A forest is a large area of land covered in trees. Forests are necessary for the survival of many animals. They are a diverse ecosystem with a diverse range of plants and animals. The two most important factors for forests are temperature and rainfall. They can't live in many places because they're too cold or too dry.
Complete answer:
Conifers, which have needles instead of leaves and cones instead of flowers, make up the majority of coniferous forests. Conifers are evergreen, meaning they produce needles all year. Conifers can survive in extremely cold or dry environments thanks to these adaptations.
There are many, but the two that are most likely to have the greatest impact are climate change and a century of fighting forest fires. Climate change has resulted in milder winters with shorter durations, resulting in a higher number of insects surviving (tent caterpillars and pine beetles are two prime examples) and subsequent infestations increasing in severity and area. In British Columbia, the lodgepole pine beetle has killed 50 percent of the trees (and climate change indirectly).
Forest fire suppression disrupts the natural process of forest succession. For example, the lodgepole pine has a lifespan of 100 years, and a forest fire occurs every 100 years or so. Only after a fire will the lodgepole pine germinate (the pine cones have a thick, spiny exterior that only opens up to disperse seeds following a fire).
Years of fighting fires have slowed the natural renewal processes that keep these massive forests alive - there are more pests and pathogens, as well as a large population of older trees that can't withstand the onslaught. Prescribed burns, in which we purposefully set localized forest fires where we have previously interfered, are common. This reduces the risk of large, catastrophic forest fires in the future.
Note:
The northern coniferous forest provides a significant amount of industrial forest products, as well as non timber forest products and environmental services, to the rest of the world. It contributes to the preservation of indigenous peoples' social fabric and culture.
