Detection of Burned Areas through Spectral Indices Analysis of Sentinel-2A Satellite Images in the Abokouamékro Wildlife Reserve (Central, Côte D’Ivoire)

In Côte d’Ivoire, the recurring and unregulated use of bushfires, which cause ecological damage, presents a pressing concern for the custodians of protected areas. This study aims to enhance our comprehension of the dynamics of burnt areas within the Abokouamékro Wildlife Reserve (AWR) by employing the analysis of spectral indices derived from satellite imagery. The research methodology began with the calculation of mean indices and their corresponding spectral sub-indices, including NDVI, SAVI, NDWI, NDMI, BAI, NBR, TCW, TCG, and TCB, utilizing data from the Sentinel-2A satellite image dated January 17, 2022. Subsequently, a fuzzy classification model was applied to these various indices and sub-indices, guided by the degree of membership α, with the goal of effectively distinguishing between burned and unburned areas. Following the classification, the accuracies of the classified indices and sub-indices were validated using the coordinates of 100 data points collected within the AWR through GPS technology. The results revealed that the overall accuracy of all indices and sub-indices declines as the degree of membership α decreases from 1 to 0. Among the mean spectral indices, NDVI-mean, SAVI-mean, NDMI-mean exhibited the highest overall accuracies, achieving 97%, 95%, and 90%, respectively. These results closely mirrored those obtained by sub-indices using band 8 (NDVI-B8, SAVI-B8, and NDMI-B8), which yield respective overall accuracies of 93%, 92%, and 89%. At a degree of membership α = 1, the estimated burned areas for the most effective indices encompassed 2144.38 hectares for NDVI-mean, 1932.14 hectares for mean SAVI-mean, and 4947.13 hectares for mean NDMI-mean. A prospective approach involving the amalgamation of these three indices could have the potential to yield improved outcomes. This study could be a substantial contribution to the discrimination of bushfires in Côte d’Ivoire.

Characterisation of Human-Wildlife Conflicts around the Kahuzi-Biega National Park, Eastern Democratic Republic of Congo

The history of mankind contains so many illustrations of well-classified and violent struggles against various animals over crop production in agricultural fields, attacks on human life or competition in order to have access to certain natural resources. The aim of this study is to characterise the human-wildlife conflicts that occur around the KBNP, especially with regard to primates. Surveys were carried out in 260 households selected using the snowball method. The results showed that human-wildlife conflicts around the KBNP are characterised by the destruction of crops in riparian fields by monkeys, chimpanzees and gorillas, the destruction of houses, physical attacks and zoonoses. Despite the conservation and protection measures for wildlife and local populations put in place by the Park’s managers, conflicts between local populations and the Park’s wild animals are still visible. These conflicts lead to the detention of wild animals by local people roaming in the villages and to poaching on the Park’s boundaries. The weakness of the community management policy on the part of the park managers and the resentment of the indigenous peoples towards the restriction of their access to natural resources are the major constraints on the sustainable management of conflicts between the local populations and the wild animals in the KBNP. The strategies for the sustainable resolution of human-wildlife conflicts around the KBNP must be geared towards and integrated into a community conservation approach.

Assessing Human-Wildlife Conflict in the Periphery of Loango National Park in Gabon

Human-Wildlife Conflict in Gabon is a reality occurring in almost all protected areas in the country. These conflicts create real threats both for the survival of wildlife species and of human beings. This study was carried out at the periphery of Loango National Park in Gabon. This area is particular of seeing elephants wandering around villages. Respondents for the study were drawn from a wide range of stakeholders (State administrators, farmers and NGOs). Data was collected through administration of structured questionnaires and interview guide on the;socio-economic activities. Crops produced/destroyed. Animals are involved and economic loss is incurred due to conflicts. Data was analysed using SPSS version 16 and Kobo tool box. For qualitative data chi-square, descriptive statistic and linear regression model were also used. The results of the study showed that the elephants account for (60.1%) of crop destroyed followed by Ungulates (30.4%) and lastly by rodents (0.9%). The economic damage caused by the wildlife to crops valued at 72,084 USD in the zone in 2022. An urgent solution to this conflict is needed because the consequences are visible as well as the illegal repression by communities that have led to poisoning and killing of wildlife in the study area.

Do Observations during Patrolling Trips Detect Changes in Wildlife Presence & Diversity in National Parks?

Globally, mountains encompass spectacular landscapes and a great diversity of species. However, Savannah’s mountains in Sudan have been affected by the loss of diversity due to human activities and climate changes. Therefore, this study aims to assess changes in wildlife diversity in Jebel-Eldair Nation Park (JENP) based on only reports from patrolling activities, especially in the absence of regular wildlife monitoring programs. Reports of monthly wildlife observations during patrolling trips were used for the summer season in 2010 and 2018. Findings showed a moderate to high decline in the most important wildlife species (i.e. lion, wild dog, and crest porcupine). Six others are documented as rare species in reserve, including the civet, spotted hyena, striped hyena, jackal, seraval, and Siberian bird. Contrary and despite the diversity reduction, some species witnessed increases in their observation frequency, such as lesser kudu, caracal, monitor, and lunar bird. Moreover, human settlements, agricultural activities, and other anthropogenic factors were found to be the main drivers of biodiversity reduction in JENP. The study recommends adopting this method to detect changes in wildlife communities, especially in a situation of deficiency and lack of funding to conduct regular monitoring programs.

Analysis of Economic Efficiency of Wildlife Law Enforcement in Serengeti Ecosystem Tanzania

Law enforcement remains to be the main strategy used to combat poaching and account for high budget share in protected area management. Studies on efficiency of wildlife law enforcement in the protected areas are limited. This study analyzed economic efficiency of wildlife law enforcement in terms of resource used and output generated using three different protected areas (PAs) of Serengeti ecosystem namely Serengeti National Park (SENAPA), Ikorongo/Grumeti Game Reserves (IGGR) and Ikona Wildlife Management Area (IWMA). Three years (2010-2012) monthly data on wildlife law enforcement inputs and outputs were collected from respective PAs authorities and supplemented with key informant interviews and secondary data. Questionnaire surveys were conducted to wildlife law enforcement staff. Shadow prices for non-marketed inputs were estimated, and market prices for marketed inputs. Data Envelopment Analysis (DEA) was used to estimate economic efficiency using Variable Return to Scale (VRS) and Constant Return to Scale (CCR) assumptions. Results revealed that wildlife law enforcement in all PAs was economically inefficient, with less inefficiency observed in IWMA. The less inefficiency in IWMA is likely attributed to existing sense of ownership and responsibility created through community-based conservation which resulted in to decrease in law enforcement costs. A slacks evaluation revealed a potential to reduce fuel consumption, number of patrol vehicles, ration and prosecution efforts at different magnitudes between studied protected areas. There is equal potential to recruit more rangers while maintaining the resting time. These finding forms the bases for monitoring and evaluation with respect to resource usage to enhance efficiency. It is further recommended to enhance community participation in conservation in SENAPA and IGGR to lower law enforcement costs. Collaboration between protected area, police and judiciary is fundamental to enhance enforcement efficiency. Despite old dataset, these findings are relevant since neither conservation policy nor institution framework has changed substantially in the last decade.

Improving Sustainability by Privatizing Wildlife Conservation

The purpose of this study is to improve environmental sustainability by identifying the most sustainable/least fragile of the three major wildlife conservation access models—open, government, and private—under varying environmental and socioeconomic conditions. The private access model is the most sustainable of the three major conservation models because it provides the best information and incentives to balance the needs of humans and wildlife, maintain general wildlife habitat, and adapt quickly to changing environmental and/or socioeconomic conditions. Government-controlled access, however, can be employed as a model of last resort if the private access model shows signs of failing to protect specific species from local extirpation or extinction, which it is most likely to do for migratory species, species with close commercial substitutes, and species with no direct commercial value. Government regulators may also be needed to enforce property rights arrangements like catch shares and to monitor resources that remain open access in case socioeconomic or environmental conditions change sufficiently to trigger the tragedy of the commons. Most treatments of wildlife regulation default to various iterations of the government access model and fail even to consider the costs and benefits of private and open access models. The analysis here instead shows the conditions in which each conservation access model is most appropriate: open when a resource is in high supply and low demand, private most of the time, and government when the others fail to slow resource depopulation/depletion.

Assessing the Contribution of Ecotourism to Economic Growth and Rural Development Offered by Wildlife Resources to People Living in Communities around Matusadonha National Park

Ecotourism is one of the major drivers of economic growth and rural development in many countries involved in wildlife resource management.The objective was to assess the contribution of ecotourism to economic growth and rural development offered to people living in communities around Matusadonha National Park.A total of 140 participants were interviewed and questionnaires were administered to the same number of people.Data were analysed using both qualitative and quantitative methods.Results show that the majority of participants(57%)were females.Safari operations were the major(54.7%)ecotourism activity in Matusadonha National Park.Above half(58.8%)of participants indicated that ecotourism contributed toward economic growth in communities around Matusadonha National Park.Most people(343)were employed on a part-time basis from 2000 to 2022.Participants indicated that the standard of living in most communities increased by more than 50%.Above 50%of participants were satisfied with the contribution of ecotourism towards rural development.It can be concluded that ecotourism has the potential to improve economic growth and rural development if close monitoring and accountability of funds are monitored closely.Local people should be included in the accountability of funds and management of wildlife resources to improve economic benefits to local people.

Evaluation of Wildlife Resource Value in Jinggangshan Nature Reserve by CVM

By using Contingent Value Method(CVM),WTP(Willingness to Pay) of wildlife in Jinggangshan Nature Reserve was studied,the overall existence value of wildlife resource(namely the sum of economic,social,ecological value added on its existence value) in this area was calculated,and the statistics of primary social and economic factors affecting payment value were analyzed.600 questionnaires had been issued altogether and the recovery rate was 100%,583 of which were valid and the effective rate was 94.2 % which demonstrated that feedback sample quantity had reached the analysis requirement.The study result showed that interviewees with different social characteristics widely dispersed,which complied with the survey principle of random sampling;that the distribution curve of WTP was neither smooth nor normal and as 50 Yuan was frequently-used amount in their daily consumption,people tended to choose this option subconsciously;that WTP had notable correlation with education degree,monthly income and cognition degree,and had relation with age but no obvious relation with gender;that annual payment value per capita was within the research scope of wildlife payment value,that is 40-575 Yuan/(person·year).The final conclusion was that wildlife resource value in this area was 17 845 000 Yuan/year,which was of great significance to the protection of biological diversity and the formulation of corresponding protective measures in Jinggangshan Nature Reserve and even in the whole society.

Concept of scientific wildlife conservation and its dissemination

In recent years, wildlife conservation has attracted great public attention. However, substantial distinctions can be found in the prevailing concepts of wildlife conservation, particularly with the recent notion that emphasizes animal rights. Wildlife welfare and wildlife rights are not synonymous, with welfare more compatible with the reasonable and legal utilization of wildlife. The key to scientific wildlife conservation is the appropriate awareness and appreciation of the relationship between wildlife conservation and utilization and the theoretical basis of holism. Nevertheless, rational biases regarding the public＇s understanding of wildlife conservation and the spread of information via social media still exist. As such, expansion of the concept of scientific wildlife conservation requires the application of several measures. Wildlife conservation researchers should be regarded as the most important disseminators of scientifically-based information, with education in schools and universities of growing importance. Furthermore, the media should shoulder the social responsibility for the accurate dissemination of conservation information.

How Is the COVID-19 Outbreak Affecting Wildlife around the World?

The COVID-19 is the infectious disease caused by the most recently discovered coronavirus at an animal market in Wuhan, China. Many wildlife species have been suggested as possible intermediate sources for the transmission of COVID-19 virus from bats to humans. The quick transmission of COVID-19 outbreak has imposed quarantine measures across the world, and as a result, most of the world’s towns and cities fell silent under lockdowns. The current study comes to investigate the ways by which the COVID-19 outbreak affects wildlife globally. Hundreds of internet sites and scientific reports have been reviewed to satisfy the needs of the study. Stories of seeing wild animals roaming the quiet, deserted streets and cities during the COVID-19 outbreak have been posted in the media and social media. The strong link between wildlife markets and COVID-19 resulted in international calls asking countries to shut down wildlife markets forever. Poorer and vulnerable people around the world overexploit natural resources including wildlife. Roadkills became minimal because of the lockdown measures. The reduction in noise pollution level is expected to improve wildlife health and ecology including breeding success. The shortage of food items provided to zoo and park animals constituted a real threat to animals and the institution harboring them. The increase in fish biomass comes as a result of the sharp decline in fishing activities. The isolation of antibodies from certain wildlife species is promising in saving humankind against COVID-19. The infection of wild and pet animals with COVID-19 virus from humans and the interspecific transmission of the infection are disastrous to animal ecology. Finally, closures may enhance people to connect more and more with nature in order to acknowledge wildlife in their surrounding environments. In conclusion, the study asks the world’s different parties to conserve wildlife in a sustainable fashion and to regulate exotic animal trade in wet markets in order to lower the incidence of zoonoses.

The prospect of wildlife tourism

The paper extends an overview of the worldwide development of wildlife tourism, introduced the conception of wild-life tourism and its components, and analyzed the development of international wildlife tourism and its international trends. The sustainability of wildlife tourism, the protection of wildlife habitat, as well as the possible impacts of wildlife tourism development in China were discussed.

Ecological Agriculture. Integrating Low Input, High Productive Farming with Wildlife Conservation. Results from the Experimental Farm La Combe, Drome France

Wildlife conservation must be integrated with energy and resource efficient agriculture for the human population to survive. Modern high input energy and resource inefficient agriculture does not address these problems. An efficient food producing system which marries wildlife conservation with resource and energy efficient human food production is needed. This is Ecological Agriculture, modelled on how natural ecosystems work. It is defined as: The establishment and maintenance of a diversified, self-sustaining low input farming system managed to maximize net production without causing large or long term changes to the environment. It must be economically viable, and ethically and aesthetically acceptable [1]. Forty years of research on 4 experimental farms have assessed the practicality of this approach (results previously published). The 5th experimental farm in the mountains of the Pre Alps has completed its 10 years. The results are discussed in relation to the tenets of Ecological Agriculture. The techniques previously developed have allowed the results to fulfil the majority of the demands of efficient ecological agriculture and to produce food for 20 families from the farm’s resources despite the difficult climate, topography and soils. It is shown how energy and resource inefficient the omnivorous animals (poultry and pigs) are, compared to herbivores. The species diversity has increased and the whole farm is a nature reserve. Aesthetic and ethical problems have been addressed with an emphasis on a life of quality for farm animals.

Anthropogenic disturbances and status of forest and wildlife in the dry deciduous forests of Chhattisgarh state in India

The advent of modem forces and the changes in socio- economic patterns of forest dwellers have increased the pressures on the forests. In order to mitigate such pressures and also to protect the forests and wildlife the model of protected areas networks has shifted and en- hanced such pressures in the unprotected natural forests due to several reasons. Being a low profile category of protected status and continuous human settlements, the present study highlights the case of dry deciduous forests of Sarguja district of Chhattisgarh state of India. The major objec- tives of this study were to quantify the status of forests and wildlife and also to determine the extent of anthropogenic disturbances faced by the dry deciduous forests of central India. Transect and silent drive count methods were used for sampling wildlife and quadrat method was used for sampling vegetation. Besides, the local uses of various forest pro- duces were also studied in view of understanding the people dependency on forests. The forest vegetation, in the study area, was pre-dominated by Shorea robusta, which had Madhuca indica, Diospyrus melanoxylon and Buchnania lanzan as the major companion species. The forest had either the high girth class mature tree species or the saplings. The low vegeta- tion cover and density were due to the high anthropogenic pressures mainly in the form of heavy livestock grazing and collection of etlmo- botanically important species. The study though reveals that the area is not rich in wildlife and the forest is fragmented, the area still supports some important species, which include many rare and endangered plants and animals. The findings of this study have been discussed in view of the management and conservation of the forest and wildlife in the dry deciduous forests.

A Preliminary Annotated Checklist of the Amphibians and Reptiles of the Kulen Promtep Wildlife Sanctuary in Northern Cambodia

We present the first herpetological checklist for the Kulen Promtep Wildlife Sanctuary in northern Cambodia, with records of 22 species of amphibians and 33 species of reptiles belonging to 44 genera in 22 families. The checklist includes three species （Ingerophrynus macrotis, Micryletta inornata, Scincella melanosticta） which in Cambodia were formerly only known to occur in the Cardamom Mountains in the southwest of the country. Our findings highlight the importance of countrywide herpetological baseline surveys in lowland habitats.

Status and distribution pattern of coarse woody debris along an altitudinal gradient in Askot Wildlife Sanctuary, Uttarakhand, West Himalaya

A rapid assessment on the status and distribution patterns of coarse woody debris （CWD） was conducted by laying five curvilinear transects （transects A, B, C, D and E; major trails）, along an altitudinal gradient starting from 900 to 2 600 m, in three major watersheds （Charigad, Dogarhigad and upper Gosigad） of Goriganga catchment in Askot Wildlife Sanctuary, India. At every 100 m rise in altitude a hectare plot （100 m x 100 m） was selected. Results showed that the percentage contribution by different succession phases was in the decreasing order： phase I 〉 phase II 〉 phase IV 〉 phase III for snags, and phase III〉 phase II 〉 phase IV 〉 phase I for logs. Snag density in chir pine forest was high in transect A （11 snags＇ha^-1） at 1 500 m, and the value in rianj oak forest was high in transect B （10 snags.ha-l） at 2 300 m. The total available mass of snags and logs in chit pine forest was 13.9 t, of which snags mass accounted for 41% of the total mass and logs mass for 59%. While the total value was 5.6 t in rianj oak forest, of which snags and logs accounted for 60% and 40% of the total mass, respectively. Moreover, the presence of CWD in the study area if not harvested, would provide a great opportunity to the orchids in future to flourish by providing protection. The high densities of snags and logs in chir pine forest at mid-altitudinal zone led to less species richness and lower density of ground flora as the zone receives more light, accompanying with lower soil moisture, and thus only the dominant species occupy the habitat.

Population Ecology of the Endangered Himalayan Yew in Khokhan Wildlife Sanctuary of North Western Himalaya for Conservation Management

The Himalayan Yew (Taxus baccata subsp. wallichiana) is an endangered native high value medicinal plant of the Himalayan Region. The several medicinal properties of the bark and leaves of this species have increased its risk of extinction due to pressures for utilization. It is also subjected to harvest for fuelwood. The species does not regenerate well from seed and that is another risk factor. The objective of this research was to investigate the population ecology of the species as a foundation for its conservation. Six forest communities in the Khokhan Wildlife Sanctuary where the species is present were sampled. The abundance of the species, impacts of harvesting and its current regeneration patterns indicate that it may soon be extirpated from the Sanctuary. A plan for conserving the remaining sub-populations is presented. It could provide a template for conservation in other locations where the species is at risk.

Evaluation of habitat quality for selected wildlife species associated with island back channels

The islands and associated back channels on the Ohio River, USA, are believed to provide critical habitat features for several wildlife species. However, few studies have quantitatively evaluated habitat quality in these areas. Our main objective was to evaluate the habitat quality of back and main channel areas for several species using habitat suitability index (HSI) models. To test the effectiveness of these models, we attempted to relate HSI scores and the variables measured for each model with measures of relative abundance for the model species. The mean belted kingfisher (Ceryle alcyon) HSI was greater on the main than back channel. However, the model failed to predict kingfisher abundance. The mean reproduction component of the great blue heron (Ardea herodias) HSI, total common muskrat (Ondatra zibethicus) HSI, winter cover component of the snapping turtle (Chelydra serpentina) HSI, and brood-rearing component of the wood duck (Aix sponsa) HSI were all greater on the back than main channel, and were positively related with the relative abundance of each species. We found that island back channels provide characteristics not found elsewhere on the Ohio River and warrant conservation as important riparian wildlife habitat. The effectiveness of using HSI models to predict species abundance on the river was mixed. Modifications to several of the models are needed to improve their use on the Ohio River and, likely, other large rivers.

A Preliminary Investigation on the Status of the Wildlife Trade in Guangxi,China

Wildlife trade is a main impetus for wildlife hunting.There are 91 species of animals,involved in the Wildlife trade in Guangxi,China,including 40 species of mammals,17 species of birds,32 species of reptiles and 2 species of amphibians.Thirty-five species,including 21 species of mammals,8 species of birds and 6 species of reptiles,are the animals under state’s special protection.Thirty species are involved in the wildlife trade between China and Vietnam.There are 55 species involved in live wildlife trade.Thirty-nine species of wildlife are used as food or raw materials for medicinal liquor.Thirty-four species are used as medicinal materials.And 31 species (not including snakes) are used as raw materials.There are 9 species Used as pets.The species richness involved in the wildlife trade in Guangxi tends to increase.Wildlife trade has caused the endangerment of many species and the decline of wildlife resources in Guangxi.The live wildlife trade between China and Vietnam can bring about an invasion of exotic species to China.It is suggested that the changes of species and volume involved in the wildlife trade should be monitored and the live wildlife trade between China and Vietnam should be prohibited in Guangxi.
