A Malaspina Promenade Arbutus
(Aka Arbutus menziesii | Pacific Madrone)
Canada's only native broad-leaved evergreen tree. They are often found in fast-draining, shallow, nutrient-poor soils on rocky outcrops, and they can grow as far south as Mexico, giving them one of the longest north-south ranges of any North American tree.

Why do they shed their bark?
The current theory is that it helps the tree shed lichens and parasites, such as boring insects, which lay their eggs on the bark. By doing this, the tree prevents their buildup, thereby reducing the chance of disease.

2. Its species name Arbutus menziesii, derives from the name of Captain Vancouver's ship surgeon, Archibald Menzies. He was also the botanist for the voyage which sighted Savary on July 1, 1792.
3. A privately owned property in Savary Shores has one of the largest Arbutus trees in BC. Unfortunately, it overhangs one of the erodings bluffs, so its days are numbered — unless they chain it to their house.
