Intensive forestry on Canada's West Coast has some impressive accomplishments but re-investments of timber capital must increase many times to meet future needs. Intensive forest management requires greatly increased inputs of labour, capital, and knowledge in order to enhance the amount and value of yields from an ultimately limited land base. Attractive incentives must be developed for private land owners and users of public forest lands to sustain current yields of wild stands, to avoid a falldown in harvest as surplus old growth values are liquidated, and to make up for withdrawals from the land base and complications of timber management.Since 1912-13 direct B.C. government forest revenues have exceeded expenditures to 1976 by $847 million. British Columbians and many other Canadians are therefore deeply in debt to the forests of British Columbia, and soon should re-invest past surpluses to help build a base for even greater returns in future.Past trends, the current situation, relation to other areas, costs, responses, sources of funds, multiple use implications, alternatives, research needs, and incentives, are discussed with special reference to the Vancouver Forest District.

Rusty Blackbird

Abstract Maintaining a functionally connected network of high-quality habitat is one of the most effective responses to biodiversity loss. However, the spatial distribution of suitable habitat may shift over time in response to climate change. Taxa such as migratory forest landbirds are already undergoing climate-driven range shifts. Therefore, patches of climate-resilient habitat (also known as “climate refugia”) are especially valuable from a conservation perspective. Here, we performed maximum entropy (Maxent) species distribution modeling to predict suitable and potentially climate-resilient habitat in Nova Scotia, Canada, for 3 migratory forest landbirds: Rusty Blackbird (Euphagus carolinus), Olive-sided Flycatcher (Contopus cooperi), and Canada Warbler (Cardellina canadensis). We used a reverse stepwise elimination technique to identify covariates that influence habitat suitability for the target species at broad scales, including abiotic (topographic control of moisture and nutrient accumulation) and biotic (forest characteristics) covariates. As topography should be relatively unaffected by a changing climate and helps regulate the structure and composition of forest habitat, we posit that the inclusion of appropriate topographic features may support the identification of climate-resilient habitat. Of all covariates, depth to water table was the most important predictor of relative habitat suitability for the Rusty Blackbird and Canada Warbler, with both species showing a strong association with wet areas. Mean canopy height was the most important predictor for the Olive-sided Flycatcher, whereby the species was associated with taller trees. Our models, which comprise the finest-scale species distribution models available for these species in this region, further indicated that, for all species, habitat (1) remains relatively abundant and well distributed in Nova Scotia and (2) is often located in wet lowlands (a climate-resilient topographic landform). These findings suggest that opportunities remain to conserve breeding habitat for these species despite changing temperature and precipitation regimes.

Long Term Experience

Abstract The multi-scale approach to conserving forest biodiversity has been used in Sweden since the 1980s, a period defined by increased reserve area and conservation actions within production forests. However, two thousand forest-associated species remain on Sweden’s red-list, and Sweden’s 2020 goals for sustainable forests are not being met. We argue that ongoing changes in the production forest matrix require more consideration, and that multi-scale conservation must be adapted to, and integrated with, production forest development. To make this case, we summarize trends in habitat provision by Sweden’s protected and production forests, and the variety of ways silviculture can affect biodiversity. We discuss how different forestry trajectories affect the type and extent of conservation approaches needed to secure biodiversity, and suggest leverage points for aiding the adoption of diversified silviculture. Sweden’s long-term experience with multi-scale conservation and intensive forestry provides insights for other countries trying to conserve species within production landscapes.

Young Forests

As young forests in many areas of Canada enter the middle and later stages of their rotations, new concerns are arising overt the future of deer populations. Analysis of silvicultural impacts on deer habitat requirements indicates that the food, cover, and water needs of deer can be met in young forests, but that most uniformly treated stands will be lacking in one more components. Mosaics of young stands, each 20–40 ha in area and at different stages of management, will provide good habitat in many areas. In areas with snowy winters, however, deer need to find all habitat components much more closely interspersed. Key words: Deer, Odocoileus hemionus, habitat requirements, winter range, intensive forestry, immature stands, old-growth, thermal cover, security cover, forage, lichens, silviculture.
