Swiss mountain forests have been well-preserved due to laws requiring reforestation and less demand for timber. However, threats to biodiversity exist, such as plantation forestry and high forest road densities. Some species, like capercaillie birds, are negatively affected. Conservation efforts include close-to-nature forest management, creating forest reserves, and specific action plans for species. A new national forest policy aims to establish reserves covering 10% of the country's forests by 2015.
