About

The Natural Resources Research Institute (NRRI), Friends of Sax-Zim Bog, and industry partners constructed a wooden boardwalk at the Sax-Zim Bog near Toivola, MN. The boardwalk is manufactured from locally-sourced Eastern larch timber, a low-value tree species threatened by the Eastern larch beetle. Prior to construction, the lumber was thermally modified to increase dimensional stability and improve decay and moisture resistance.
