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.","PeriodicalId":129797,"journal":{"name":"Journal of Ecosystems and Management","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123937942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hodge","doi":"10.22230/jem.2011v12n2a94","DOIUrl":"https://doi.org/10.22230/jem.2011v12n2a94","url":null,"abstract":"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.

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.","PeriodicalId":129797,"journal":{"name":"Journal of Ecosystems and Management","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128424136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
