habitat. water resource protection and recreation (Kline et al.. 2004;
Pouta, 2005; Donnegan, 2007) . Public lands in the U.s. also face a dilemma:
these lands are no longer managed primarily for wood production
and there is a strong need to quantify the value of some of
the public goods and services provided from these lands (Kline.
2006; Boyd and Banzhaf, 2007; Collins and Larry. 2008). Emerging
markets for ecosystem services present some new opportunities for
forest landowners and managers. Besides the economic contributions
of timber and other forest products. there is increasing recognition of
the importance of ecosystem services and the values (public goods)
these services provide (Costanza et al.. 1997; Casey et at., 2006:
Farley and Costanza. 201 0) . These emerging markets offer financial
incentives for landowners to maintain and manage their forests rather
than developing these lands. There is a compelling need to assess
some of the different ecosystem services provided from forest lands
and the potential role of market-based incentives to maintain these
services.
The importance and value of ecosystem services are being recognized
from local to global scales (Costanza et a!.. 1997; Daily, 1997;
Kroeger and Casey. 2007; Farley and Costanza, 2010; LaRocco and
Deal. 2011) . The term "ecosystem services" was popularized by ecologists
who recognized the value of natural processes and products.
and their intrinsic importance to enhance human well being and ecosystem
services were defined as the "biological underpinnings
