ABSTRACT<br />
Aspen (Po/>ulus tremuloides Michx.) <strong>and</strong> <strong>balsam</strong><br />
<strong>poplar</strong> (P. <strong>balsam</strong>ifera L. ) represent about 40% <strong>of</strong><br />
Alberta's forest resources, but utilization is only 1% <strong>of</strong><br />
the total available. Decay <strong>and</strong> sla<strong>in</strong> are two major factors<br />
limit<strong>in</strong>g utilization <strong>of</strong> these species. Major <strong>decay</strong>-caus<strong>in</strong>g<br />
agents <strong>and</strong> types <strong>of</strong> <strong>decay</strong> <strong>of</strong> <strong>aspen</strong> <strong>and</strong> <strong>balsam</strong> <strong>poplar</strong><br />
are reviewed, <strong>and</strong> the implications for management <strong>and</strong><br />
utilization are discussed.<br />
