Located in Unalaska, Alaska is the Sitka Spruce Plantation, a historic area known for being the oldest recorded afforestation project by the Russian government. It was established in 1805 as an attempt to make the region of Unalaska and its settlement self sufficient in timber.

The area of the Sitka Spruce Plantation was originally and naturally treeless. This is why the area was chosen to become a plantation. In 1834, there were 24 trees that stand in the area. In 1970, at least 6 original trees are still present in the site. However, the original number of trees planted is unknown, so making a clear comparison is not possible.

Due to its role as the oldest afforestation project in the North American continent, the Sitka Spruce Plantation was declared a National Historic Landmark in 1978.
