sustainable forestry

• Sustainable forests would be mixed species, they provide more niches, manages soil better which result in a higher biodiversity. 
• A mixed age structure provides a structural diversity, different food sources - leaves, fruits, DOM - breeding sites and hibernation sites. 
• Selective cutting and strip felling leaves canopy, and reduces soil erosion and maintains habitat. 
• 80% of trees are imported, UK timber industry is worth £2 billion - 40,000 workers. 
• Afforestation sequesters CO2 and increases cloud cover. 
• Afforestation may reduce biodiversity if its planted on a particular habitat - changes abiotic conditions. It also depends on the species planted, native vs non-native, monoculture vs mixed variety; native species will provide habitat for native wildlife. 
• Drax is a biomass power station located in north Yorkshire. It uses biproducts of the timbre industry to provide energy by making pellets and burning them. Drax was accused of cutting down environmentally important forests in Canada.
