4.1. WTP for Balkan Chamois Conservation
A large proportion of the participants were WTP for chamois conservation by paying an annual tax for implementing a five-year conservation plan. Based on the mean annual WTP, a considerable amount could be collected annually. The funds necessary for the conservation of chamois populations are not known but, considering the total amount of money that could be secured, we expect that a new annual tax would be sufficient for implementing conservation plans. Although considerable, a further increase in public support, as expressed by WTP proportions, would be desirable because, in addition to necessary funds, public support is also critical for successful wildlife conservation [
7,
8].
Illegal hunting is considered a major threat to wild mammals globally, more so to small and isolated populations [
51,
52]. Illegal hunting has also been recognized as the major threat to chamois in the study area [
2,
4]. Chamois meat and skin are both valuable in the market. Preliminary investigations have revealed that chamois are predominantly hunted for their skin and that both Greeks and Bulgarians participate in illegal actions [
2,
4]. However, reliable data on the intensity of illegal hunting and its exact drivers are lacking, and hence, the long-term consequences for the chamois population cannot be assessed. Possible social and economic drivers of illegal hunting include poverty and income generation, demand for wildlife products, recreational needs, trophy acquisition, and a behavioral intention to hunt illegally [
53]. Future research should determine both the current and future effects of illegal hunting on chamois populations and its proximate and underlying drivers. In doing so, support for the caprine will increase, and its future will be brighter.
Our results fell within and to the upper part of the 31% to 80% WTP rates and EUR 0.0 to EUR 71.2 mean WTP reported from similar studies [
11,
12,
14,
15,
19,
20,
40,
54]. This trend did not change after adjusting for inflation and GDP (see Table 4 in Liordos et al. [
24]). These findings suggest that there is considerable interest in chamois conservation among the Greek public. Higher WTP values have been generally reported for mammals and birds [
11,
14,
19,
20] than for reptiles and amphibians [
13,
23] but not always [
12,
15]. The public favors the conservation of endangered mammals and birds in comparison to reptiles and amphibians [
7,
30]. Previous studies have shown that factors such as phylogenetic resemblance to humans [
55,
56] and physical size [
57] are associated with support for endangered species conservation. Additionally, mammals, birds, and fish have a positive social construction, as opposed to reptiles and amphibians [
58]. A mean WTP of EUR 21.7 for bat conservation was estimated in a comparable study in Greece [
24]. It seemed that the Greek public valued more chamois than bats since it would allocate to them more than double the amount that would allocate to bats. Chamois are charismatic, medium-to-large-sized mammals, while bats, although mammals themselves, are among the most unlikeable and feared and least supported conservation species [
7,
30].
4.2. Predictors of WTP
Attitudes toward chamois were positively associated with higher proportions and amounts of money of WTP for their conservation. Additionally, an observation of the species in the wild improved the proportions and amounts of WTP. On the other hand, knowledge about chamois’ ecology, biology, and habits was positively associated with WTP proportions among our sample participants but not with monetary WTP. Previous studies that have commonly reported that people with positive attitudes toward and observation of certain species, including mammals such as the brown bear (
Ursus arctos), red deer (
Cervus elaphus), pygmy rabbit (
Brachylagus idahoensis), cougar (
Puma concolor), tiger (
Panthera tigris), leopard (
Panthera pardus), and giant panda (
Ailuropoda melanoleuca), are associated with higher support and WTP for their conservation [
7,
19,
25,
26,
27,
30]. Other studies have also shown that knowledge about wildlife in general and certain species in particular improved behavior toward and WTP for the conservation of species, such as snakes [
25,
59], marine turtles [
60], and sharks [
61]. Knowledge is seen as a prerequisite for someone’s behavior [
62], influencing individuals’ valuations of environmental commodities [
63]. However, although important, knowledge about biodiversity has been a relatively minor factor in predicting whether members of the public will know about specific pro-environmental behaviors they can take, whether they will actually undertake such behaviors, and whether they will support their conservation [
64], as compared with attitudes, charisma, knowledge of a species, and its phylogenetic resemblance to humans [
7,
30,
65,
66,
67,
68]. In line with these findings, attitudes toward and knowledge of chamois’ existence were more important predictors of WTP than knowledge about the caprine’s ecology, biology, and habits in our study. It seemed that being able to recall the image of chamois in someone’s brain functioned as a positive stimulus. The chamois’ figure, posture, and physical size most likely invoked positive emotions and attitudes due to its phylogenetic proximity to humans [
65,
68].
Moralistic worldviews were positively associated with the proportion and, more so, with the amount of WTP for chamois conservation. Dominionistic worldviews were negatively associated with the amount of WTP. People with moralistic values are fervent champions of animals and nature in general and, therefore, are expected to support actions for their conservation [
42]. In contrast, those with dominionistic values are utilitarian and give priority to wildlife use over conservation. Those who hold moralistic worldviews are more supportive of endangered species conservation than those who hold dominionistic worldviews [
7,
30]. Overall, moralistic worldviews were better predictors of WTP for chamois conservation than dominionistic worldviews. Previous studies have also found that moralistic cognitions are better predictors of wildlife conservation [
7,
8,
30], while dominionistic cognitions are better predictors of wildlife impact management [
69,
70,
71,
72]. As expected, survey participants who intended to participate in chamois conservation actions were also more WTP for its conservation. People who participate in wildlife conservation actions have a special interest in wildlife, have or acquire knowledge about wildlife in general and certain species in particular, are champions of animal welfare, and are opposed to wildlife management strategies that can harm wildlife [
73].
Participants who were engaged in wildlife-related consumptive activities were more WTP than participants who did not engage in such activities. Consumptive users of wildlife, such as hunters and fishers, are nature enthusiasts that enjoy nature and wildlife and have a special interest in conservation issues, especially those concerning their favorite game, and often engage in conservation actions. [
35,
36]. Greek hunters had greater knowledge of the existence and about the ecology, biology, and behavior of wildlife species, both game and non-game, than non-hunters [
74]. The greater experiential knowledge of consumptive users about wildlife, their interest in wildlife conservation, and the increased possibility to encounter chamois in the wild might explain their greater support and WTP for the conservation of the species.
Our results show that a high amount of WTP was associated with females and a high level of education. High income was associated with both high proportions and a high amount of WTP. In a comparable CVM study in Greece, WTP was associated with a high level of education but not with gender or income [
24]. Other similar studies have reported variable findings. Gender, income, and educational level were associated with WTP for gray wolf (
Canis lupus) and Mexican free-tailed bat (
Tadarida brasiliensis mexicana) conservation [
11,
37]. Educational level and income were positively associated with WTP for white stork (
Ciconia Ciconia) and giant panda conservation. Gender, income, and educational level did not affect the WTP for the conservation of the tiger and the Mauritian flying fox (
Pteropus niger) [
54,
75]. As WTP increased with income in our study, it represented a “normal good” for the Greek residents according to economic principles [
76].
Attitudes, worldviews, participation in conservation actions, educational level, income, and being female were stronger predictors of the amount than the proportion of WTP. This larger effect on the amount than the proportion of WTP of these factors suggests that conservation initiatives should focus not only on increasing the proportions of those not WTP for chamois conservation, such as those with more negative attitudes, less moralistic and dominionistic worldviews, who do not participate in conservation actions, are male, and have low education and income but also those that were WTP. Given that the second WTP model included only those WTP for chamois conservation, the stronger effect of the above-mentioned factors suggests that there was variation in the amount they were WTP among those with more positive attitudes and moralistic and dominionistic worldviews, who participate in conservation actions, are female, and have high education and income. In doing so, both higher support and larger funds would be secured for the conservation of the species. On the other hand, knowledge, non-consumptive recreational activities, and having seen the species in the wild were better predictors of the amount than the proportion of WTP. This suggests that there was a threshold above which an increase in knowledge, non-consumptive users, and those who have seen the species in the wild did not improve the amount of WTP.
4.3. Management Implications
Survey participants stated support and WTP for the conservation of chamois. The collection of necessary funds through an annual tax would be sufficient for effectively applying suitable conservation actions, especially controlling illegal hunting of the chamois population and determining its drivers in the study area [
2,
4]. Outside the study area, wildlife corridors are necessary for connecting population groups, especially in the Pindus Mountain range. Attitudes toward chamois were neutral and knowledge about the species average. Additionally, our results reveal that attitude was positively associated with the proportion and amount of WTP, while knowledge was positively associated only with the amount of WTP for chamois conservation. These results suggest that there is room for a further increase in attitudes and knowledge, which in turn will increase the support and WTP—a prerequisite for the caprine’s successful conservation [
7,
8].
Public education and outreach programs should be designed and implemented, aiming at increasing the knowledge of people about chamois distribution and conservation status, especially in the targeted areas, biology, ecology, and behavior. Experiential activities, such as chamois observation and identification of biomarkers would also improve knowledge about and attitudes toward the species [
77]. Such programs and activities should be primarily addressed to groups that the results identified as having low support for chamois conservation, such as those with more negative attitudes, less knowledge and moralistic and dominionistic worldviews, who have not seen the species in the wild and do not participate in consumptive activities and conservation actions, are male, and have low education and income. Additionally, the greater effect of several factors on the amount than the proportion of WTP suggests that considerable variation also existed within groups with a higher amount of WTP, such as those with more positive attitudes and moralistic and dominionistic worldviews, who participate in conservation actions, are female, and have high education and income. Such groups should also be the target of education and outreach campaigns. Outreach campaigns should also aim at discussing suitable conservation actions with the public [
78]. Actions that are not perceived well by the public might not be acceptable and, thus, jeopardize the conservation outcomes.
