Challenges of socio-economically evaluating wildfire management in and adjacent to non-industrial private forestland in the Western United States [PDF]

, 2007
Non-industrial private forests (NIPFs) in the United States generate many unpriced benefits for both the landholder and society generally. These values can be enhanced or diminished by wildfire management in situ and on adjacent public land.
