Research to identify ecotourists or segment ecotourists from other tourist types has not occurred in a consistent manner, reducing potential comparability to studies at other times and places. Ecotourists have been identified using a variety of techniques, broadly categorised as tourist typologies that are cognitive-normative and interactional. This paper tests the level of congruency among four versions of these tourist typologies (ie. researcher-based,respondent-based, activity-based, and motivation-based), using a case study from a national park in northern Thailand. Based on the considerable consistency found, several pragmatic conclusions are presented.
IntroductionAs refinements are made to the definitions and conceptual frameworks for ecotourism (e.g. Björk, 2000;Blamey, 1997;Diamantis & Ladkin, 1999;Hvenegaard, 1994), a major problem in ecotourism research remains. Research to identify ecotourists or segment ecotourists from other tourist types has not occurred in a consistent manner. It is necessary to include situation-specific information in this process, but this may lead to results that are not comparable with studies at other times and places. Such comparability is necessary to generalise about studies that deal with important ecotourism issues such as environmental impacts (Blane & Jaakson, 1994), community impacts (Lindberg et al., 1996), conservation involvement (Hvenegaard & Dearden, 1998), motivations (Eagles, 1992, and demographics (Eagles & Cascagnette, 1995).Attempts to define tourist types have also been called segmentation, classification, and clustering. Identifying distinct tourist types is beneficial for the planning, management, and marketing of tourism (Smith & Smale, 1980;Taylor, 1986). Tourist typology information allows managers to address different motivations, experiences, and impacts of tourist types (Diamantis, 1998;Eagles, 1992) and to understand which tourist types are more likely to be found at different stages in the evolution of tourism areas (Duffus & Dearden, 1990). Moreover, in terms of sustainability, it is necessary to use a tourism typology to match tourism types to resource capabilities (Wall, 1993).A variety of techniques are available to identify ecotourists or to distinguish ecotourists from other tourist types (Blamey, 1997;Bottrill & Pearce, 1995). For example, many studies consider tourists entering a particular site to be ecotourists (e.g. Lindberg et al., 1996;Tobias & Mendelsohn, 1991). Other studies consider all tourists engaging in particular activities (Ceballos-Lascurain, 1991) or participating in certain tours to be ecotourists (e.g. Diamantis, 1998;Eagles, 1992). Some studies use both site and activity criteria (e.g. Wall, 1994 Only a few studies use motivational information to identify ecotourists. For example, Ballantine and Eagles (1994) define ecotourists as respondents who:answer 'very important' or 'somewhat important' to 'learning about nature' as a motivation when planning a trip; and answer 'very important' or 'somewhat important' to 'wilder...
