The Economic Benefits of Elk Viewing at the Jewell Meadows Wildlife Area in Oregon

Abstract

In this study a travel cost model is used to

Recreational users' willingness to pay and preferences for changes in planted forest features

“…We present results for NB and ZTNB models only as the ZTNBES model while correcting for endogenous stratification in our data did not converge. As mentioned earlier, non-convergence in the estimation of a ZTNBES model is not surprising at it had also occurred in other studies (e.g., Donovan and Champ, 2009). In addition, similar studies have found that correcting for on-site sampling bias sometimes offers little or no improvement in estimation (Ovaskainen et al, 2001;Englin et al, 2003).…”

“…To address the issues of over-dispersion and over-sampling of frequent users, we also employ the ZTNB regression model with endogenous stratification. A reported limitation of this third model is problems of convergence (Donovan and Champ, 2009). As the three models mentioned above are well documented, we refer the reader to Hilbe (2007, p. 164-167) and Haab and McConnell (2002, p. 175) for an overview.…”

Effects of Browsing by Captive Elk (Cervus canadensis) on a Midwestern Woody Plant Community

“…This data gap leaves land managers and citizens near the restoration areas unprepared to understand or deal with the consequences, beneficial and deleterious, of reintroducing a large herbivore into an environment greatly altered from its historic character, such as through the absence of major predators and an increased level of human activity. The benefits of reintroduction are obvious: the beginnings of ecosystem restoration and increased ecotourism and hunting revenues in reintroduction areas (Donovan and Champ, 2009). In contrast, the possible positive and negative consequences on the surrounding ecosystem have thus far escaped scrutiny, although studies of western elk provide some insight.…”

The Economic Value of Viewing Migratory Shorebirds on the Delaware Bay: An Application of the Single Site Travel Cost Model Using On-Site Data

“…There are several estimates for broad categories such as nonconsumptive wildlife recreation (Rockel & Kealy, 1991) and wildlife viewing for other species such as elk (Donovan & Champ, 2009). There are also a number of studies that have estimated non-use values for endangered or threatened species of birds such as the Spotted Owl (Rubin, Helfand, & Loomis, 1991), the Red Cockaded Woodpecker (Reaves, Kramer & Holmes, 1999), and Canada geese (MacMillan, Hanley, & Daw, 2004).…”

“…Englin and Shonkwiler (1995) later introduced an on-site correction for negative-binomial models. For some recent applications along these lines and similar to ours see Donovan and Champ (2009), Ovaskainen, Mikkola, and Pouta (2001), McKean, Johnson, and Walsh (1995, Englin, Holmes, and Sills (2003), and Martínez-Espiñeira and Amoako-Tuffour (2008).…”
