A Report on the Management of Saltwater Crocodiles (Crocodylus porosus) in the Northern Territory: Results of a Survey of Pastoralists AgEcon
Tisdell, Clement A.; Wilson, Clevo; Swarna Nantha, Hemanath.
The management of saltwater crocodiles (Crocodylus porosus) in the Northern Territory is an important component of the State’s wildlife management policy. It encompasses saltwater crocodile control (the removal of problem crocodiles dangerous to humans and livestock), and the regulation of harvesting, farming and ranching of saltwater crocodiles for the production of commercial products. The distribution of saltwater crocodiles and their habitats often extend onto private and communal lands along the coastal belt of the Northern Territory, and therefore are a concern of landholders both Aboriginal and pastoral. This report presents the findings of a study of managers of Northern Territory cattle properties (pastoralists). Their attitudes are surveyed...

A Study of the Impact of Ecotourism on Environmental Education and Conservation: The case of Turtle Watching at an Australian Site AgEcon
Tisdell, Clement A.; Wilson, Clevo.
The importance of environmental education as a component of ecotourism is highlighted. The extent of environmental education and its impact on attitudes to conservation of sea turtles and actions by ecotourists to support such conservation as a result of their visits to Mon Repos Conservation Park (Queensland), an important marine turtle rookery, is examined. To do this, results from 519 usable survey forms completed by ecotourists are analysed. It is found that a considerable amount of environmental education is obtained by visitors and that this has positive and statistically significant impacts on their desire to protect sea turtles and their intended actions to do so. The importance of the interaction of tourists with wildlife as a contributor to...

An Initial Assessment of Policies for Saving a Rare Australian Glider: Experimental Results, Economics and Ecology AgEcon
Tisdell, Clement A.; Wilson, Clevo; Swarna Nantha, Hemanath.
Reviews the ecological status of the mahogany glider and describes its distribution, habitat and abundance, life history and threats to it. Three serial surveys of Brisbane residents provide data on the knowledge of respondents about the mahogany glider. The results provide information about the attitudes of respondents to the mahogany glider, to its conservation and relevant public policies and about variations in these factors as the knowledge of participants of the mahogany glider alters. Similarly data is provided and analysed about the willingness to pay of respondents to conserve the mahogany glider. Population viability analysis is applied to estimate the required habitat area for a minimum viable population of the mahogany glider to ensure at least...

Attitudes to entry fees to national parks: results and policy implications from a Queensland case study AgEcon
Wilson, Clevo; Tisdell, Clement A..
Examines visitor attitudes and whether visitors are willing to pay to enter Lamington National Park and under what circumstances they would do so. First a sample of visitors is asked a general (normative) question as to whether visitors should pay to visit Lamington National Park and in another question (positive) they are asked whether they would be more willing to pay if the money collected would be invested in the park to improve visitor facilities and for conservation work. The results show that visitors are more willing to accept the ‘user-pays’ principle if the money will be used for the benefit of the national park and its visitors. It was found that foreigners are more in support for a ‘user-pay’ fee than Australians, and among Australians, those...

Australian Tropical Reptile Species: Ecological Status, Public Valuation and Attitudes to their Conservation and Commercial Use AgEcon
Tisdell, Clement A.; Wilson, Clevo; Swarna Nantha, Hemanath.
Five species of reptiles present in tropical Australia are considered in this study. These are the hawksbill turtle (Eretmochelys imbricata); the northern long-necked turtle (Chelodina rugosa); the taipan snake (Oxyuranus scutellatus); the freshwater crocodile (Crocodylus johnstoni); and the saltwater crocodile (Crocodylus porosus). Background information is provided on the ecological status of each of these species and after outlining their human use (including commercial use) and management in Australia, an experimental survey method is introduced and results from its application are reported and analysed. The survey method involves two serial surveys of a sample of 204 Brisbane (Australia) residents. The first survey is based on the initial knowledge...

Birds in an Australian Rainforest: Their Attraction for Visitors and Visitor's Ecological Impacts AgEcon
Tisdell, Clement A.; Wilson, Clevo.
Lamington National Park in Queensland, Australia is noted for its rainforest and is part of the World Heritage listed property but prior to this work, no systematic study has been done of the importance of birds to its visitors. This study is based on data from survey forms handed to visitors at an important site in the park and completed by visitors following their visit. It yielded 622 useable responses. These enabled us to establish the comparative importance of birds as an attraction to this site for this sample of visitors. Furthermore, logit regression is used to target analysis and to identify factors that increase the likelihood of a visitor saying that birds are an important attraction. In addition, the relative importance to visitors of...

Breeding and feeding pigs in Australia and Vietnam AgEcon
Tisdell, Clement A.; Wilson, Clevo.
This report establishes that ACIAR Research Project AS2/1994/023, ‘Breeding and feeding pigs in Australia and Vietnam’ (supported by ACIAR from July 1995 to the end of 2000) has yielded an extraordinarily high rate of economic return on the funds invested. The collaborating agencies were the Department of Primary Industries, Queensland, James Cook University and The University of Queensland in Australia, and the Institute of Agricultural Sciences of South Vietnam in Vietnam. The best estimate benefit–cost ratio for investment in this project is at least 159:1 with a corresponding internal rate of return of 900% and a net present value of A$496 million. This is a total value, not an annual value. To give context to the number A$496 m, in 2000, 1.3 million...

Comparative Public Support for Conserving Reptile Species is High: Australian Evidence and its Implications AgEcon
Tisdell, Clement A.; Wilson, Clevo; Swarna Nantha, Hemanath.
This paper investigates factors influencing the public’s support for conservation of tropical reptile species in a focal group drawing on Australian data and an experiment involving a sample of the Australian public. The influences of the likeability of the species, their degree of endangerment, ethical considerations as well as knowledge are examined and found to be important. Likeability is found to be much less important than the existing literature suggests. This is highlighted by comparing the likeability of the focal group of reptiles with that for a group of birds and a group of mammals with differences in willingness to pay for their conservation.

Conservation and Economic Benefits of Wildlife-based Marine Tourism: Sea Turtles and Whales as Case Studies AgEcon
Wilson, Clevo; Tisdell, Clement A..
Tourism development can have positive and/or negative impacts on wildlife. However, if tourism is developed in accordance with the basic tenets of wildlife tourism such an activity can be sustainable and can aid the conservation of species. Based on two case studies in Queensland, Australia, this article outlines the various economic and conservation benefits arising from wildlife-based tourism. Some of the benefits are direct, such as tangible economic benefits, others are less tangible, such as increased visitors’ willingness to pay in principle for the conservation of species. Wildlife-based tourism is shown to foster political support for the conservation of species utilized for such tourism by various mechanisms. Non-consumptive uses of wildlife are...

Dependence of public support for survival of wildlife species on their likeability AgEcon
Tisdell, Clement A.; Wilson, Clevo; Swarna Nantha, Hemanath.
We surveyed a sample of 204 individuals selected from the public in Brisbane, Australia, to ascertain the extent to which they like or dislike 24 species of wildlife present in tropical Australia. The species belong to three classes: mammals, birds and reptiles. We calculated likeability indices for each of these species. We also asked respondents if they favoured the survival of each of these species and so the percentage of respondents favouring survival of each of these species could be calculated. Thus, using linear regression analysis, the percentage of respondents favouring survival of each of the species was related to their indices of likeability. In addition, the data enables the average likeability of species in the three classes (mammals, birds...

Developing Ecotourism for the Survival of Sea Turtles AgEcon
Tisdell, Clement A.; Wilson, Clevo.
Discusses generally why humans should bother to conserve sea turtles. In doing so, it considers both economic and non-economic reasons and outlines threats to the existence of sea turtles and ways in which tourism may either contribute to the conservation or decline of their populations. Turtle-based ecotourism at Mon Repos in southern Queensland is described. As a result of a survey conducted by the authors, it is shown that turtle-based ecotourism at Mon Repos has positive social (indirect) consequences for the conservation of sea turtles. Furthermore, it is argued that ecotourism operations at Mon Repos have positive direct impacts on the sustainability of populations of sea turtles. However, using a simple model, it is demonstrated that this impact is...

Does Ecotourism Contribute to Sea Turtle Conservation? Is the Flagship Status of Turtles Advantageous? AgEcon
Tisdell, Clement A.; Wilson, Clevo.
There is little doubt that marine turtles are a flagship species for wildlife tourism. In some cases, this has turned out to be liability for sea turtle conservation, but in other cases, where for example turtle-based ecotourism has been developed, it has made a positive contribution to turtle conservation. Examples of both cases are given. Particular attention is given to the development of turtle-based ecotourism at Mon Repos Beach near Bundaberg, Australia. This development is set in its historical context and its contribution to conservation is discussed. Headstart projects for sea turtles in Sri Lanka are a tourist attraction. While they are promoted as having positive conservation consequences and a survey indicates that visitors are on the...

Dynamic Processes in Contingent Valuation: A Case Study Involving the Mahogany Glider AgEcon
Tisdell, Clement A.; Wilson, Clevo; Swarna Nantha, Hemanath.
This paper reports the results of an experiment involving a sample of 204 members of the public who were assessed on three occasions about their willingness to pay for the conservation of the mahogany glider. They were asked this question prior to information being provided to them about the glider and other focal wildlife species; after such information was provided, and finally after participants had had an opportunity to see live specimens of this glider. The mean willingness to pay of the relevant samples are compared and found to show significant variations. Theories are considered that help explain the dynamics of these variations. Serious concerns are raised about the capacity of information provision to reveal ‘true’ contingent valuations of public...

Dynamic Processes in the Contingent Valuation of an Endangered Mammal Species AgEcon
Tisdell, Clement A.; Wilson, Clevo; Swarna Nantha, Hemanath.
Reports experimental results involving 204 members of the public who were asked their willingness to pay for the conservation of the mahogany glider Petaurus gracilis on three occasions: prior to information being provided to them about the glider and other wildlife species; after such information was provided, and after participants had an opportunity to see live specimens of this endangered species. Variations in the mean willingness to pay are analysed. Concerns arise about whether information provision and experience reveal ‘true’ contingent valuations of public goods and about the choice of the relevant contingent valuation measure.
