Savenac Nursery Historic District, Historic district near Haugan, Mineral County, Montana, United States.

Savenac Nursery Historic District lies near Haugan in Mineral County, Montana, 15 miles from St. Regis. The site holds ten buildings constructed in the 1930s by Company 956 of the Civilian Conservation Corps, along with landscaped grounds, a stone bridge, interpretive trails and a small arboretum.

Established in 1907 by forester Elers Koch, the nursery became the largest tree production facility in the northwestern United States, producing over 12 million seedlings annually until operations ceased in 1969.

The district represents the conservation movement and New Deal era programs, with ten buildings constructed by Civilian Conservation Corps Company 956 exemplifying Colonial Revival architecture and federal work initiatives.

Visitors can access the site via Interstate 90 at exit 16, where parking is available near historic structures, interpretive displays, and walking trails through the preserved nursery grounds.

The Great Fire of 1910 destroyed the nursery itself, not the reverse: Elers Koch, who founded Savenac in 1907, also helped fight that blaze. The site was rebuilt and kept producing seedlings until 1969, when its operations moved to the Coeur d'Alene Nursery in Idaho.
