Analysis of the economic benefits associated with the recovery of threatened marine mammal species in the Canadian St. Lawrence Estuary

This paper examines Canadians' willingness to pay to recover the populations of three marine mammal species found in the St Lawrence Estuary. The valuation approach utilized a stated preference tool that is somewhat a hybrid between contingent valuation and a choice experiment with multiple species recovery program options and choices framed as referenda. Program options involved the use of a marine protected area and restrictions on whale watching and shipping industries. The estimated willingness to pay (WTP) for different levels of marine mammal recovery ranged from $77 to $229 per year per household and varied according to the species affected and the recovery program effort. A series of tests revealed that people would be willing to pay more for programs that contribute to greater increases in marine mammal populations, but the additional value of programs that improve a species status beyond the “at risk” threshold is relatively small.

► Willingness to pay for marine mammal recovery programs in the St Lawrence Estuary was estimated.
► Stated preference methods were used and employed 6 scenarios varying costs, regulations and species outcomes.
► Willingness to pay for different levels of recovery ranged from $77 to $229 per year per household.
► Economic values were higher for programs generating greater increases in the species populations.
► The additional value of programs improving these species beyond an “at risk” threshold was small.
