The mountain pine beetle (Dendroctonus ponderosae Hopkins; MPB) infestation has altered forests of lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) to an unprecedented extent in British Columbia. After an MPB outbreak, advance regeneration significantly contributed to form a new canopy and stand; however, the time needed to form a new stand depends on site-specific conditions. Assessment of regeneration and the growth of residual trees in stands after MPB attack are critical for three purposes: (1) forecasting long-term development (yield) of attacked stands; (2) selecting stands for growth-improving silvicultural treatments; and (3) forecasting impacts to ecological attributes such as hydrology, habitat, and vegetation types. This article reviews and synthesizes recent research concerning lodgepole pine stand performance after MPB attack in British Columbia. Species composition, abundance, spatial distribution, and overall stand health are described. This information is important for forest managers or practitioners who make decisions regarding management of MPB-attacked stands. Moreover, a number of key gaps exist in our knowledge about factors affecting advance regeneration and the residual trees of MPB-attacked stands. This article presents a list of knowledge gaps for management information and further research initiatives.

Laminated (or Phellinus) root disease (Phellinus sulphurascens Pilát, syn. = P. weirii) is a major, naturally occurring disturbance agent in interior forests and poses a significant threat to its most economically important host, Douglas-fir. The disease spreads below ground at root contacts. In the southern interior of British Columbia, P. sulphurascens often occurs together with Armillaria root disease (Armillaria ostoyae) and (or) Douglas-fir bark beetle (Dendroctonus pseudotsugae). Stand volume in infested areas can be significantly reduced through growth loss and decay, mortality, and windthrow. Post-harvest retention of infected stumps in the soil increases inoculum potential on affected sites, which poses a risk of infection to regenerating trees. Mitigation of disease impacts can best be achieved by recognition of the disease and incidence assessment prior to harvest, and by modification of harvesting and silviculture practices that will minimize exposure of trees to inoculum. The Stand Establishment Decision Aid (SEDA) format has been used to extend information on various vegetation and forest health concerns in British Columbia. This decision aid summarizes information about laminated root disease occurrence and management in the Southern Interior Forest Region. The first sections provide general information, hazard ratings, and biological and silvicultural considerations for Phellinus root disease. The article then outlines growth and yield implications, other effects and associations of the disease, and various techniques to manage the disease. It also includes a list of references and resources to provide readers with more detailed information. Reference material that is not available online can be ordered through libraries or the Queen’s Printer at http://www.qp.gov.bc.ca.
层积根病(Phellinus sulphurascens Pilát, syn. = P. weirii)是一种主要的、自然发生的干扰因子，对其最重要的经济寄主道格拉斯冷杉(Douglas-fir)构成重大威胁。这种疾病通过根部接触在地下传播。在不列颠哥伦比亚省南部内陆，P. sulphurascens常与蜜环菌根病(蜜环菌ostoyae)和(或)道格拉斯冷杉树皮甲虫(Dendroctonus pseudosugae)一起发生。受侵染地区的林分体积可因生长损失和腐烂、死亡和风阻而显著减少。收获后被感染的树桩在土壤中的滞留增加了受影响地点的接种潜力，这对再生树木造成了感染的风险。减轻疾病影响的最佳办法是在采伐前确认疾病和评估发病率，并修改采伐和造林做法，以尽量减少树木受到接种的影响。在不列颠哥伦比亚省，使用了林分建立决策援助(SEDA)格式来提供关于各种植被和森林健康问题的信息。本决策文件总结了南部内陆林区层状根病害发生和管理的相关信息。第一部分提供了一般信息，危害等级，以及生物学和造林方面的考虑。文章然后概述了生长和产量的影响，其他影响和联系的疾病，和各种技术来管理的疾病。它还包括一个参考文献和资源列表，为读者提供更详细的信息。网上没有的参考资料可以通过图书馆或女王印刷厂(http://www.qp.gov.bc.ca)订购。

The Central Interior Ecoregional Assessment brought together professionals from the Nature Conservancy of Canada, provincial government ministries, and academic researchers, to complete a conservation-based scientific analysis of the Central Interior region of British Columbia. Four principal products emerged from this effort: conservation portfolios, Marxan summed solutions, conservation value maps, and a comprehensive compilation of conservation data for the ecoregion. With the completion of this assessment, NCC has developed conservation plans for the vast majority of British Columbia.

We present a vulnerability-based approach for considering climate as a threat in regional conservation planning. The protocol is based on best available understanding of the climate sensitivity of species and systems of concern, has little reliance on climate or ecological change scenarios, and can be executed rapidly. This approach has advantages of (1) not being tied to environmental scenarios with high uncertainty and (2) generating ‘no regrets’ strategies for planning for climate in the context of other threats. The approach was implemented in an ecoregional assessment of the British Columbia Central Interior. Regional strategies to reduce climate vulnerability were applied to set conservation targets and goals in the site-selection process. These had a wide-ranging impact on both freshwater and terrestrial conservation assessments. Selection of high-priority areas based on climate strategies generally (1) increased the number, size, and connectivity of selected areas, (2) included and expanded on areas selected using standard protocols, (3) drew more on moderately favorable areas, and (4) showed similar outcomes for different parts of the domain, but with some selection bias to more northern areas and higher reaches of drainages. These planning outcomes adhere to the ‘no regrets’ goal—enhancing the adaptive capacity of species and systems to multiple threats while taking heed of a climate threat. The resulting plan sets the regional stage for on-the-ground climate-wise strategies by providing for larger, less fragmented, and more connected conservation sites and with restoration as a complementary strategy to reduce ecosystem vulnerability.
