The project involves work to develop a synthesis of the published literature on the multi-stand (landscape) effects of salvage harvesting in mountain pine beetle (Dendroctonus ponderosae) affected areas, to identify key principles that affect wildlife habitat and biodiversity at the landscape level, to articulate these in the design of multi-stand salvage harvest retention strategies, and to suggest and illustrate possible approaches to retaining landscape-level wildlife habitat and biodiversity that relate to existing landscape condition. The key purpose of the work is to develop a synthesis on the likely landscape level effects of salvage harvesting in mountain pine beetle affected areas on wildlife habitat, and to identify options that will help to mitigate these effects in a cost effective manner. The proposed project represents a second phase of work initiated in 2005/06 on developing a synthesis of information regarding the stand-level impacts of salvage harvesting on wildlife habitat in mountain pine beetle affected areas. The earlier work began in 2005 and led to the completion of a Southern Interior Forest Region extension note in May 2006 (Retention Strategies to Maintain Habitat Structure and Wildlife Diversity During the Salvage Harvesting of Mountain Pine Beetle Attack Areas in the Southern Interior Forest Region (Klenner 2006, see http://www.for.gov.bc.ca/hfd/Pubs/RSI/FSP/EN/RSI_EN04.htm). This extension note was a first step in the stand-level retention extension project, and serves to focus discussion and application of the concepts addressed in the document to operational salvage practices in mountain pine beetle affected areas. Application of the concepts outlined in the stand-level extension note is ongoing via relatively informal field-based workshops with operational field staff from SIFR district offices and licensees, discussions with the Southern Interior Implementation Team, and presentations at formal workshops such as SISCO. We propose to develop a complementary landscape-level salvage retention extension product that would: (1) outline key principles relating to maintaining wildlife habitat and biodiversity at the landscape level, (2) articulate these principles and relate them to the design of operational landscape salvage harvest retention strategies, (3) to suggest and illustrate possible approaches to retaining landscape-level wildlife habitat in the context of pre- and likely post-salvage habitat pattern and the nature of stand-level retention in individual salvage harvest blocks that make up the landscape, and (4) use a landscape-level habitat supply model (TELSA, see Klenner et al. 1997, 2000, Kurz et al. 2000, ESSA 2005) to illustrate the likely outcomes of different management scenarios. We will use an extensive literature review of landscape-level wildlife habitat issues and dialogue with operational staff and planners to develop an extension document similar to Southern Interior Forest Region Extension Note EN04. The review will focus on specific landscape-level features that are important to wildlife and biodiversity, and develop a synthesis relating to retention planning to maintain wildlife habitat in landscapes where extensive salvage harvesting is projected to occur (e.g. more than 30% of the lodgepole pine leading forest types are salvage logged). A preliminary list of factors to review includes: (1) the amount of mature and late seral, (2) patch size and shape of mature and late seral retention areas, (3) the dispersion of key habitats, (4) landscape-level connectivity, (5) representation of ecosystem types in old and mature retention areas at the predictive ecosystem mapping level, (6) the effects of roads and access, (7) maintaining heterogeneity of treatments, and (8) the role of within-stand structural conditions. A key backdrop to the synthesis will be the recognition that the mountain pine beetle has affected a major change to the pattern and process of the ecosystem, ...
