In March 1992, it adopted the new plan based on the prestigious "Thomas report" setting aside about 8 million acres of old-growth forest for spotted owl habitat.
There now seems to be a renewed sense of closure to the issue. This case clearly shows how the particular institutions of the US forest policy regime affected both the strategy and the resources of environmental 43 44 George Hoberg groups and contributed to their success. The environmental strategy in this case can be boiled down to two tactics: nationalization and judicialization. The victory would not have been possible had the issue continued to be constructed in regional terms, as forest policy traditionally had been.
Both systems have experienced strong pressures for change in recent years. Because policy making in both the US Pacific Northwest and British Columbia is embedded in larger political systems, the magnitude of potential change in policy styles is limited. Hoberg argues that the United States has been more successful in preserving old-growth forests but that forest management in British Columbia has changed substantially in response to pressure from environmentalists. Although the political institutions of the two countries differ, from a global forest products perspective they act as a single region.
