What's this?

This tree is a native of the Pacific Northwest, and a staple to most forested regions in the area. These trees thrive in biodiverse environments filled with decaying matter, and can often be found near or on nurse logs, making the Pacific Northwest the perfect place for them to find biological success. These trees, at a glance, are tall and bushy, with erratically placed branches and foliage.
