Old growth logging has been slowly crimped in B.C. over the years, but measures announced Tuesday could see it grinding almost to a halt in the most contentious stands of timber. The NDP government… is going to temporarily defer harvest of another 2.6 million hectares scattered in patches all over the province. …Deferring logging on that scale is a significant move. It constitutes a big reduction in the harvest that will have drastic impacts on the forest industry and it will start immediately. …The deferrals are not considered full protection — yet. They’re billed as temporary two-year measures to allow for new management approaches to be developed. But it’s hard to imagine logging resuming in those areas to any degree, now that the lines have been drawn on the map. …But there is still about 2.4 million hectares unprotected, most of it big trees. Preservationists are on a winning streak and will be setting their sights on the rest.
