Fire damage soils our forests
Article Abstract:
The impact of forest fires may be ecologically constructive, and may lead to vegetation development and ecosystem succession. The loss of organic materials in the surface layers of the soil improves the germination of seeds, by providing easier access to mineral soil. The fire product, charcoal, improves the water-retentive characteristics of soil. This property of waterlogging may create conditions appropriate for peat formation. Charcoal also adsorbs phenols which are important compounds for soil ecology. Burning may also activate microbial populations.

Hunting ground for farmers
Article Abstract:
Farmers cleared out forests consisting of deciduous trees as a means of habitat management for enhancing hunting activities before the idea of agriculture came into being. The first signs of cereal farming can be seen in pollen diagrams of lake sediments. It was abandoned as a consequence of soil exhaustion and poor crop productivity. The concept of cereal growing was an afterthought and poor idea.
