AMC Title 21 Tree Code identifies heritage white spruce, paper birch, and quaking aspen above defined diameter thresholds for retention review, balancing urban forest preservation with wildfire defensible-space needs in beetle-affected stands.
The Anchorage Tree Code embedded in AMC §21.07 designates white spruce, paper birch, black cottonwood, and quaking aspen above 18 inches diameter at breast height as candidate heritage trees subject to retention plans during platting and major site development. The 1990s spruce bark beetle outbreak killed millions of mature trees across Southcentral Alaska, complicating preservation by elevating wildfire risk; consequently, beetle-killed dead spruce are exempt from retention. Healthy mature stands trigger arborist reports and replacement requirements when removed for development. The Urban Forestry program of the Parks and Recreation Department maintains the inventory and reviews permits.
Removing protected heritage trees without arborist review and Tree Code permit incurs civil penalties up to $1,000 per tree under AMC §21.07 plus mandatory replacement at 2:1 to 4:1 ratios.
