Clear cutting is the extensive harvesting of trees in an area and its biggest drive is agriculture. Furthermore, there are various approaches even to just defining a forest ecosystem. Coniferous forest, vegetation composed primarily of cone-bearing needle-leaved or scale-leaved evergreen trees, found in areas with long winters and moderate to high annual precipitation. The acidic, infertile soils of coniferous forests are called podzols. There are some exceptions to this, most notably in the US Pacific Northwest. Commonly, these trees are evergreen, meaning they are green and able to photosynthesise all year round. Being considered the largest land-based biome, it covers over 15% of Earth’s total land area.

In some, needleleaf trees dominate, while others are home primarily to broadleaf evergreen trees or a mix of both tree types. Predation.

The canopy layer consists of the tallest trees, while the understory layer consists of plant life growing above the forest floor but beneath the forest canopy. The most important abiotic feature of a forest ecosystem may not be obvious, despite its ubiquity and importance: sunlight. The biggest threat to Coniferous forest is clear cutting.
