Several of the largest forestry companies in Canada have reached an agreement with environmental groups that will restrict logging in the country's vast northern forests.
In return, the environmentalists will end an international campaign against buying Canadian lumber.
The BBC reports the deal covers almost 700,000 square km, an area more than 2.5 times the size of New Zealand.
Logging will be totally banned on some of the land. Timber companies hope the deal will bring commercial gains, as timber buyers seek higher ethical standards.
