BIG Trees of the Pacific Northwest

The International Society of Arboriculture (ISA) 2012 annual conference was held in Portland, OR.  The Pacific Northwest afforded the opportunity to experience some of the world’s largest trees in Washington’s Olympic National Park and along the Oregon coast.


Along the road to the Hoh Rain Forest, one of the largest Sitka spruce trees in the US at over 270′ tall & 12.5′ in diameter.


The Duncan Cedar, the world’s largest Western Redcedar at 178’ tall & 19.4’ in diameter.


The Cape Meares Sitka Spruce stands 144’ tall and 15.5’ and is the largest of its species in Oregon.


The Octopus Tree is a massive Sitka spruce near Oregon’s Cape Meares Lighthouse. Its branches, growing like giant tentacles, were created by the ravages of coastal winds.


The Quinault Big Cedar is thought by some to be over 1,000 years old.
