Traditional species choices for reforestation in the sub-boreal spruce (SBS) forests of \"\"Central Interior BC tend to be historically limited to mainly spruce and lodgepole pine, Douglas-fir on some warmer sites, and subalpine fir (mainly through natural regeneration). However, two other tree species native to the BC Interior, western larch (Larix occidentalis<\/em>) and western redcedar (Thuja plicata<\/em>), show intriguing potential for adding to the species diversity and management of second-growth SBS forests. \u00a0 Initial experience and observations suggest that western larch is best suited to warmer, better-drained, lower brush-hazard sites in the sub-boreal, while in contrast, western redcedar will be suited to some moist cool seepage sites with higher brush hazards.<\/p>\n

One to two decades of operational experience with pilot outplanting studies and trials of western larch in both the Aleza Lake Research Forest (ALRF) in the eastern SBS zone, and Houston, Granisle, and Burns Lake areas in the central to western SBS (Chewter, 2006), indicate excellent performance and adaptability of this larch species to sub-boreal sites. Recent work by Barry Jaquish of the \u00a0BC Ministry of Forests and Range, \u00a0Kalamalka Research Station <\/a>has indicated that the current<\/em> climate of many low- to mid-elevation areas of the sub-boreal plateau are highly suitable to the productive growth and management of western larch, and that this geographic climatic envelope may expand \u00a0in the future as climate potentially warms in these areas.<\/p>\n

<\/div>\n
Based on present climates, western redcedar is likely to be most suitable to the wet and very wet subzones of the SBS, and recent climate modeling by the BC Ministry of Forests and Range suggests that these subzones may<\/div>\n
increasingly resemble the climate of the Interior Cedar-Hemlock zone, if current trends continue (Hamman and Wang, 2006). Operational experience with cedar plantings in SBS forests is more limited than larch; however, 5- to 12-year-old cedar plantings at the ALRF are showing some success to date.<\/div>\n

The ALRF has recently established an operational program to incorporate some western larch and redcedar plantings \u2014 and other minor species – \u00a0 into its annual reforestation objectives. The initial goal is for 3-4% of the +<\/span> 100,000 trees planted annually at the ALRF to be \u2018less-conventional\u2019 minor species. This adaptive management program will be accompanied by detailed documentation, mapping, and monitoring of such innovative plantings to provide opportunities for long-term assessment and research. In coming years, the ALRF will also be outplanting some other minor species, potentially including black spruce (Picea mariana<\/em>), western white pine (Pinus monticola<\/em>), tamarack (Larix laricina<\/em>), and other species.<\/div>\n

To support this program, the ALRF has teamed up with Steve Storch and John Orlowsky of UNBC\u2019s I.K. Barber Enhanced Forestry Laboratory <\/a>to produce 2,500 western larch and 2,000 western redcedar seedlings in Winter 2009\/10, for outplanting at the research forest in the 2010 field season. The team has selected British Columbia Class A western larch seed from the southeastern BC Interior, and Class B western redcedar from the Robson Valley district near McBride, BC.<\/p>\n

Further EFL production of larch, cedar, and other minor species for Aleza research forest plantings is planned to continue in future years. This long-term partnership between the EFL and ALRF will \u00a0even more strongly link EFL activity to operational applications, provide teaching opportunities for students at UNBC, as well as spur many opportunities for related EFL and ALRF research and demonstration projects, in terms of both nursery and field applications.<\/p>\n

This innovative collaboration of research and operations is part of the long-term vision of the I.K. Barber Enhanced Forestry Laboratory, to help ensure resilient and sustainable silviculture and \u00a0forest management for BC forests, now and into the future.<\/p>\n
