The travel cost method (TCM) and contingent valuation method (CVM) wer
e used to evaluate the economic value of six different ecotourism acti
vities involving observation of wildlife in Pennsylvania. The six acti
vities were: catch-and-release trout fishing; catch-and-release trout
fishing with fly-fishing equipment; viewing waterfowl; watching elk; o
bserving migration flights of raptors; and seeing live wildlife in an
environmental education setting. TCM results provided significant stat
istical relationships between level of use and travel costs for the tw
o types of trout fishing activities. CVM provided estimates of consume
r surplus for the other four sites. The consumers' surplus value (1988
dollars) of all six activities to participants amounted to a total of
more than $1.28 million annually-twice the total out-of-pocket expend
itures of approximately $640,000 spent to visit the sites. The economi
c amenity values of the six activities compare favorably with similarl
y derived values in other studies for hunting, fishing, hiking, and ba
ckpacking in dispersed recreation environments and wilderness areas in
western states.
