Background: The African ebony tree is a multipurpose tree native to the Guinea-Congolese forest. Its long-term viability and sustainability are threatened by the conversion of primary forest to agricultural land. To conserve the species, it is necessary to evaluate the local community's understanding of its usage and conservation strategies to identify the factors that could potentially influence the species' long-term viability in the study area.
Methods: Data was collected between June and August 2022. The random sampling method was used to administer structured and semi-structured interview questionnaires to 301 villages living within three to nine kilometers of the Campo-Ma'an National Park's boundaries.
Results: Several parts of the plant are used by the locals, notably the wood and bark, with a citation frequency of 49% and 20.4%, respectively. Cutting is the most important collection method, with a relative frequency of citation of 49.1%. These parts are valued in six categories of uses; timber was the most cited (UV = 38.9%), followed by traditional medicine (UV = 36.9%). Wood was the only part of the plant that generated considerable annual income for the local communities (52.537 USD). The vulnerability index showed that the ebony tree is highly vulnerable (IV = 2.5) in the study area.
Conclusion: The results obtained show strong pressure from local populations on D. crassiflora, leading to a decrease in the tree population.
Conservation Implications: Given the ongoing threat to D. crassiflora in the study area, this research will assist in valorising the species usage in traditional medicine and as a commercial wood. In addition, we have proposed conservation strategies like assisted regeneration and community-led planting projects to promote long-term plantation-based D. crassiflora production to mitigate the effects of deforestation.

Background and Research Aims: The natural habitats of aphyllous vanillas in Madagascar have been extensively degraded by human activities. The implications of this degradation are complex given their intricate interactions with other organisms. This study highlights possible approaches to the conservation of aphyllous vanillas after examining the impact of forest degradation on phorophyte diversity, reproductive modes, and genetic diversity.
Methods: We conducted comparative studies of conserved and degraded forests in two contrasting bioclimatic zones. We characterized the changes in horizontal and vertical forest structures and assessed the ecological importance of the tree species. We identified the preferred phorophytes of two aphyllous Vanilla species, Vanilla madagascariensis and Vanilla decaryana, and investigated their population genetics.
Results and Conclusions: Our findings confirmed a declining trend in tree diversity, number of trees, and cover rate in degraded forests. Canopy openness is associated with an increase in the number of phorophytes and the asexual reproductive mode of Vanilla species. Dominant tree species were more likely to become phorophytes, and there was a positive correlation between phorophyte diameter and number of hosted vanilla individuals. Significant deviations from the Hardy-Weinberg equilibrium were observed in each population, particularly in the dry forest and degraded sites, compared with the conserved sites. Additionally, slight differentiation was observed between vanilla populations in conserved and degraded forests, with an alarming effective population size (Ne) that did not exceed 13 individuals.
Conservation Implications: We recommend the introduction of new genotypes to promote genetic enrichment, the ban on logging potential phorophytes, and the inclusion of some degraded forests comprising Vanilla species in conservation.
Background and Research Aims: Tree planting holds significant potential for environmental protection in the era of climate change and variability. It is particularly crucial in semi-arid areas where tree density is extremely low, necessitating the engagement of local communities. However, information about local people's awareness and their willingness to participate in greening practices is rarely considered. We assessed the levels of community awareness, the extent of participation, and the factors influencing their willingness to green the Dodoma semi-arid area between 2018 and 2022.
Methods: We collected data from 145 respondents using a household questionnaire survey, focus group discussions, and in-depth interviews. Quantitative data were analyzed using SPSS version 26, while template analysis was applied to the qualitative data.
Results: We found the overwhelming majority of respondents (n= 136) are aware of the importance of tree planting, and 89.7% of respondents participated in greening practices. Income level, education level, environmental awareness, perceived benefits of tree planting, and social influence were significant predictors of communities' willingness to plant trees.
Conclusion: Despite the greater awareness and active participation of tree planting found among local actors in the study area, efforts must be directed towards suitable selection of adaptive, affordable and improved tree species for sustainable and feasible socio-ecological benefits of afforestation in semi-arid areas.
Implications for conservation: The study underscores the potential of community awareness and participation in tree planting for environmental conservation and the sustainable supply of forest products, which are vital for local livelihood development. We advocate for the consideration of socioeconomic and ecological factors when engaging local actors in greening urban semi-arid lands through technical and financial empowerment.
Background and Research Aims: Human-wildlife conflict is a significant issue worldwide mainly in developing countries where livestock husbandry and crop production are important aspects of rural people’s livelihoods and income. This study on human-wildlife conflict was conducted in and around Chebera-Churchura National Park from September 2019 to August 2021. The main aim of the study was to investigate the extent of human-wildlife conflict in the study area.
Methods: Data were collected using semi structured questionnaire and direct observation on crop damage. Descriptive statistics was used to analyze the collected data and responses were compared by using chi-square test (χ2) and one-way ANOVA.
Results: The result indicated that problems encountered by the local people due to wildlife species were crop damage (99.2%), livestock predation (67.8%), disease transmission (28.8%) and human attack (11.9%). According to the report of those who are affected, the average number of livestock predated by wild animals in and around Chebera Churchura National Park was 2.69±0.17 per household per year. Maize was the most highly affected crop type by different raiders in the study area, for instance the average maize loss by olive baboon (Papio anubis) was 303 ETB (Ethiopian Birr) (6USD) per household per year. Generally, the loss of the total estimated cost of all crop types during the study period due to crop raiders was 320,515.00 ETB (Ethiopian Birr) (6410 USD).
Conclusion: Conflict has occurred in the study area for many years and the rate of conflict is increasing from time to time.
Implications for Conservation: Integrated conflict mitigation measures should be implemented by the park administration and stakeholders to alleviate the problem and ensure sustainable coexistence of wildlife and human in the area.
Background and Research Aims:Colophospermum mopane provides many benefits including mopani worms, firewood, timber for construction, and medicine. Despite C. mopane playing a significant role in the lives and livelihoods of communities within their range, they are destroyed because of unsustainable harvesting practices coupled with lack of management practices. Assessment of people’s attitudes has become significant in studies dealing with the conservation of biodiversity. This study aims to assess the attitudes of local communities in and surrounding Giyani in Limpopo Province in South Africa towards the mopane tree and to determine if their attitudes relate to obedience to traditional rules and regulations.
Methods: Interview-administered questionnaires were used to systematically select 161 households in Muyexe village and 82 households in Nsavulani village. The questionnaire evaluated the biographical data of respondents, knowledge of mopane woodlands, importance of mopane trees and mopani worms, and their attitudes towards mopane tree conservation.
Methods: The overwhelming majority of respondents in both villages had positive attitudes towards mopane trees for ethical reasons. Respondents were also positive that mopane trees should be protected for future generations. The positive attitude of most respondents relates to obedience to rules and regulations that do not allow cutting of wet C. mopane. Respondents only cut dead or dry mopane woodlands for fuelwood. Cutting or harvesting was done on a subsistence and sustainable basis.
Conclusion:The communities have shown that they are guardians of C. mopane. The study concluded that mopani worms serve a mechanism for C. mopane conservation in Muyexe and Nsavulani villages in South Africa.
Implications for Conservation:The positive attitudes of local communities, and obedience to the customary rules and regulations is a positive sign not only for ethical reasons, but also for long-term mopane woodlands conservation. This approach encourages the long sustainability of mopane woodlands in the study area.

Background and Aim: Knowledge of population size is crucial for efficient conservation planning. Limited population survey data exist for the Endangered Preuss’s monkey in Cameroon’s Ebo forest, a stronghold for this species and several other IUCN RedList species. In this study, we assessed the population size of Preuss’s monkey in the Ebo forest. Methods: Ecological data on Preuss’s monkey and evidence of anthropogenic disturbances were collected based on recce surveys. Encounter Rate was used to assess abundance and distribution, and for comparing relative abundance among four survey sites. We employed ANOVA to test for significant differences in encounters with Preuss’s monkey across sites in the Ebo forest. We used regression analysis to identify possible relationships between encounters with Preuss’s monkey and anthropogenic activities recorded. Results: Based on direct sightings, we observed 66 individuals residing in 11 groups. This resulted in an encounter rate of 0.15_individuals/km, a sighting frequency of 0.024_groups/km, and an encounter frequency of 0.062_groups/km of Preuss’s monkeys. On average, an encounter rate of 2.4_signs of anthropogenic activities/km was documented. Our results revealed a negative and significant correlation between encounters of Preuss’s monkey and human activities such as hunting signs, logging signs, evidence of planted crops, collection of Non-Timber Forest Products, and fishing activity. Conclusion: Our investigation indicates that the population of Preuss’s monkey in the Ebo forest totals approximately 481 individuals, which is consistent with their Endangered status. Implications for Conservation: We recommend continued monitoring and research on this population to better determine the specific drivers of their population decline. We also advocate a community conservation approach to incentivize local communities to take a more active role in preserving the forest and protecting Preuss’s monkey. Equally important, are programs of conservation education and awareness, in an attempt to inspire local people to become involved in this species conservation.
Background and Research Aims: The bushmeat trade is one of the main drivers of faunal extinction in tropical Africa. We assess the profitability of the bushmeat trade along the commodity chain in southern Benin and study the perceptions of the actors on the profitability of the trade. Methods: Data were collected through direct interviews. A total of 120 bushmeat trade actors were interviewed in southern Benin. Economic and financial indicators were estimated and compared using descriptive statistics. Factors affecting the actors’ perception of wild animal hunting, trading or supply sustainability were assessed using binary logit. Results and discussion: A total of 15 species were traded along the bushmeat commodity chain in southern Benin. During the dry season, hunters’ gross product is higher because of greater hunting effort, and traders earn more commercial margin. Throughout the chain of actors, bushmeat trade profitability is seen as positively affected by the number of hunters per household and the availability of large preys (hunters), household size (sellers) and monthly income (consumers); whereas negative factors affecting profitability are distance from hunting sites (hunters), supply issues (sellers) and the cost of the meat (consumers). Both hunters and consumers see hunting and trade regulation measures as negatively impacting bushmeat profitability. Conclusion and implications for conservation: The perception of profitability by bushmeat commodity chain actors in southern Benin is conditioned by a set of socio-economic factors that should be considered in national conservation policies and development programs to keep bushmeat hunting profitable and sustainable.
Background and Aim: The native range of the African hippo has contracted significantly due to various anthropogenic threats such as poaching and habitat destruction, thus making the species highly prone to extinction. Protected areas can safeguard hippo populations through legal restrictions and other effective strategies. However, knowledge, perceived threats, and benefits of the species can influence local people’s attitudes towards their conservation. Yet, gaps in our understanding of what people know about hippos and their conservation persist, especially in Ghana, where their population is vulnerable, thus requiring urgent research.
Methods: To improve this knowledge deficit, we employed a mixed-methods research approach to collect data from household heads in five communities in the Bui National Park (BNP) landscape for descriptive and regression-based statistical analyses.
Results: Our findings revealed that respondent’s knowledge of hippos was significantly influenced by education and exposure to the species. Several respondents reported relatively stable or declining population patterns for hippos and attributed the causes to poaching and the construction of the hydropower dam in the BNP. Most respondents wanted hippo populations to increase in the future due to the potential benefits they could derive through tourism while the remaining respondents wanted their numbers to decline due to perceived conflict situations such as boat capsizing and crop damage.
Conclusion: Local people’s knowledge of the hippo and its conservation is influenced by education and exposure to the species, and its population is perceived to be declining due to human activities.
Implications for Conservation: Authentic and meaningful engagements among diverse stakeholders (e.g., farmers, fishermen, and park authorities) in the BNP landscape are critical to ensuring hippo conservation based on our findings. In particular, community-wide education to enhance hippo literacy, avoidance of farming along riverbank habitats, and adoption of sustainable livelihood approaches may benefit the aquatic environment, hippos, and local people.
Background and Aims: The rising global population has increased land demand due to the increased need for agricultural and settlement spaces. Land ownership security tremendously impacts environmental sustainability because it influences ecological decisions. Kenya's land ownership and land use changes nexus has not received sufficient attention. Consequently, we explored this research gap in Mwatate Sub County, Taita County, Kenya. Methods: A sample size of 301 households was selected using stratified proportionate and simple random sampling techniques. A cross-sectional survey research design was used, while data was collected using semi-structured questionnaires. The Neo-Malthusian theory was adopted as a theoretical framework. Results: Results revealed that most (85.6%) households had insecure land ownership rights. Most (64.1%) households inherited land and had no Title deeds. Accordingly, findings reveal unsustainable land use practices, including deforestation, tree logging, high fuelwood use, bush clearance for human settlement and cultivation, poor farming methods, and overreliance on agriculture for livelihood. Using a 95% confidence level, Chi-square tests revealed a significant relationship between agricultural land use changes and land ownership security. Our findings concluded that insecure land ownership influenced agricultural expansion, deforestation, clearing of land for human settlement, and the type of farming techniques adopted by farmers. Implications for Conservation: Taita Taveta is a vital biodiversity hotspot that continues to be degraded by human activities. The correlation between land ownership and land use changes established by our study confirms the impending land degradation and threat to biodiversity loss. This is coupled with the concern that approximately 62% and 11% of the county are under a National Park and sisal estates, respectively, implying a growing threat to biodiversity loss and the need for enhanced conservation efforts in the area. This calls for the need to address the constant land issues in the area to incentivize sustainable land use practices.
Background & Research Aims: Understanding how people and wildlife coexist is crucial to informing conservation and management of biodiverse areas, supporting both wildlife conservation and human well-being. Yet, most studies of human-wildlife conflict and coexistence focus on a limited number of wildlife species. Methods: This study characterizes patterns of reported human-wildlife conflict in the Okavango region of Botswana based on records for all species from the Botswana Department of Wildlife and National Parks (2008 – 2016). Results: The reported incidents implicated a diverse range of wildlife species in conflict. The patterns indicated that for conflicts like crop and property damage, only a few main species were implicated, while livestock damage reports had more diversity of conflict species. Additionally, people in this region faced wildlife challenges throughout the year. Conclusion & Implications for Conservation: Having such variable types and timing of conflict, and from diverse species, may make it particularly difficult for people to mitigate costs and prevent further conflicts.
Background and Research Aims: Morphological and physiological effects of anthropogenic metals have been the focus of several studies in the Sierra de Huautla Biosphere Reserve (REBIOSH, Mexico) but little is known about how they affect anurans in the area. We evaluated metal bioaccumulation in anurans from streams in the REBIOSH and examined anuran communities in five sites at different positions relative to abandoned mine tailings.
Methods: Three and two sites were located upstream and downstream from mine tailings, respectively. We collected anuran community information and obtained sediment, water and liver samples for metal quantification from each site.
Results: Concentrations of Cu, Pb, Zn and Mn in water, and Zn, Mn, Fe and Cr in sediment, were significantly different among sites. We found bioaccumulation of Pb, Zn and Fe in livers of Smilisca baudinii, Lithobates spectabilis, L. zweifeli and Rhinella horribilis, species with different life traits. We found similar among-site species richness and diversity. Communities were dominated by L. zweifeli, R. horribilis and S. baudinii. Dominance was highest in sites distant from mine tailings. Agalychnis dacnicolor, Tlalocohyla smithii and Hypopachus variolosus were only present in sites located closest to mine tailings.
Conclusion: We did not detect an effect of metal bioacummulation on anuran communities, but our findings suggest a potential effect on certain species in the protected area. Our results form a baseline for future explorations of the impacts of metals in the region.
Implications for Conservation: Toxic metal bioaccumulation has potential for reducing anuran genetic variability and altering sexual proportions and fecundity, potentially leading to anuran extirpations. We provide first evidence for metal bioaccumulation in anurans in the protected area, and one of few studies on its anuran communities. Our evidence can serve as guidance to ameliorate effects of legacy metal mining in this biodiversity hotspot.
Background and Research Aims: Globally, crocodile ranching programs are intended to generate livelihood benefits for local communities and incentives for crocodile conservation. However, there is need for their contextual scientific evaluation in many human-dominated tropical landscapes. We investigated the anthropogenic threats to crocodiles, and examined the level and sociodemographic determinants of their utilization in lower River Tana basin, Kenya.
Methods: We conducted seven key informant interviews, four focus group discussions and a quantitative household survey involving 365 respondents randomly selected from local villages. We analyzed anthropogenic threats to crocodiles and other qualitative data thematically. We summarized quantitative data using descriptive statistics and used multinomial logistic regression to analyze the association between selected sociodemographic variables and crocodile utilization.
Results: The main anthropogenic threats to crocodiles were agricultural expansion into their habitat, their retaliatory killing, and consumption of their meat and eggs. Only 5% of the respondents utilized crocodiles legally, whereas 32% utilized them illegally. Increasing age, increasing income, being male and being Christian all increased the likelihood of illegal crocodile utilization. Being male increased the likelihood of legal crocodile utilization, whereas increasing age decreased this likelihood.
Conclusions: Our study demonstrates multiple anthropogenic threats to crocodiles in lower River Tana despite a long-term ranching program. Furthermore, local community participation in this program is marginal and markedly varies among sociodemographic groups. Taken together, our findings suggest that crocodile ranching, as practiced in this landscape, is largely ineffective in achieving its intended socioeconomic and conservation goals.
Conservation Implications: To enhance their effectiveness, crocodile ranching programs in such landscapes should be tailored for local socio-cultural contexts. We recommend capacity building and awareness raising initiatives tailored for specific groups to increase local community participation in sustainable crocodile utilization and minimize their engagement in practices that are detrimental to crocodiles.

Background and Research Aims: Soil quality (SQ) is the basis for the Sustainability of Peasant Farming Systems (PFS). We hypothesized that different land uses modify soil quality through changes that can be analyzed by determining the Soil Quality Index (SQI).
Methods: Soil samples were collected from the 0-20 cm layer in five subsystems of peasant agroecosystems located in the municipalities of Solânea (A), Casserengue (B), and Serraria (C). SQI was calculated using non-linear scoring, while a principal component analysis was performed using all data (bulk and particle density, total porosity, particle size, pH, macronutrients, and soil organic carbon) to determine a Minimum Data Set (MDS).
Results: The MDS composed of P available, Ca+2, Al+3, sand, silt, H+Al, base saturation (BS%), and the aluminum saturation (AS%) indicate that these parameters can serve as indicators for soil quality assessment in peasant agroecosystems. Sand and silt are related to pedogenic processes and parent material, while the remaining indicators reflect management practices. Land conversion from forest to cropland decreased nutrient availability and soil organic matter in agroecosystems A (Arenosol) and B (Luvisol) and increased the cation exchange capacity in agroecosystem C (Lixisol).
Conclusions: All agroecosystems showed low SQI values, highlighting the need to expand conservation practices in the studied agricultural subsystems, especially regarding the increase of soil organic matter. Our results contribute to improving the use and management of soils and the vulnerability assessment in peasant farming, an essential requirement for the sustainability of agroecosystems.
Implications for Conservation: Our results also demonstrated that agroforestry practices can significantly increase soil quality and soil carbon sequestration, a viable alternative for maintaining organic matter in areas susceptible to degradation.
Background and Research Aims: Porcupines are frequently traded in Asia but evidence of this remains undocumented. This study was undertaken to address the dearth of information on porcupine trade dynamics using Malaysia as a case study.
Methods: To accomplish this, traditional Chinese medicine (TCM) outlets throughout the country were surveyed, the existence of porcupine farms were determined and porcupine seizures in Malaysia from 2011 – 2019 were analysed.
Results: The data revealed that porcupines are coveted predominantly for bezoars used in TCM and for breeding stock. Porcupine bezoars were found in 90% of TCM outlets surveyed though it is likely that the market consists of genuine and fake products. Porcupine farming appears to be gaining popularity and predominantly caters to a demand for breeding pairs. There were 47 seizures amounting to 110 porcupines of at least three species. Seizures included mostly live animals but also meat and quills.
Conclusion:The harvesting and consumption of porcupines is legally permitted in Malaysia. However, it is evident that illegal hunting of porcupines is also occurring. Captive breeding is unlikely to reduce poaching of porcupines considering the high value associated with wild-sourced bezoars. Local use is also driving international trade of bezoars particularly from Indonesia.
Implications for Conservation: Research on porcupine trade dynamics in Southeast Asia is limited. This is a conservation concern particularly as porcupines are valued as commercial commodities. As Asian porcupines face a multitude of synergistic threats (i.e., habitat loss, human conflict and illegal hunting), understanding these cumulative impacts on wild populations is a conservation priority. More research on international trade dynamics is also warranted as it is currently occurring without any regulation or monitoring. Listing porcupines in the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) could potentially mitigate this.
Background and Research Aims: Little information exists on the breeding behavior of the Andean Condor (Vultur gryphus). Its global population, estimated at 6700 adult individuals, is declining throughout its distribution range. With less than 150 condors, the Endangered condor population in Ecuador is of conservation concern. This study aimed to analyze the breeding behavior of wild-born Andean Condors in Ecuador. Methods: Between 2009 and 2021, we monitored 22 egg-laying attempts in eight Andean Condor nests, evaluated the parental care of three breeding pairs of condors and recorded the species' interactions with other raptors and mammals during the nestling-rearing season, and examined the breeding success of an Andean Condor pair during a decade of monitoring. Results: Our breeding records indicated that Andean Condor lay eggs throughout the year, and 16 nestlings spent between six and 10 months in the nest before making their first flights. We found differences in the length of time that the parents remain with the nestling, and described agonistic encounters between condors and other raptors and a Spectacled Bear (Tremarctos ornatus) in the condor nesting areas. The breeding success of the monitored condor pair was 0.88 nestlings per clutch, and the female laid an egg on average every 15 months. Conclusion: Considering the small size of the Andean Condor population in Ecuador, studies on the breeding behavior of wild-born condors are a high research priority to assess population trends and prevent extinction. Specifically, we recommend further research on parental care, breeding success, nestling survivorship, and nesting phenology. Implications for Conservation: Beyond the importance of the protected area system, strategic planning of key areas for the maintenance of condor populations in the northern Andes must encompass the evaluation of new potential protected areas that offer direct benefits to these birds. These should include nesting sites in human-dominated landscapes such as rural Andean areas.
Within developing countries, awareness efforts that promote wildlife conservation are not only important to engage communities neighboring wildlife habitats, but they are also critical nationally because urban dwellers are not usually exposed to wildlife. Here, we suggest that media and public relations professionals can promote domestic tourism activities, and engage communities in ways that will encourage the public to protect wildlife. We outline examples of successful ongoing initiatives we have used that stem from the principles of strategic communication to promote wildlife conservation in Uganda. First, tours with journalists, celebrities, and politicians have been launched to support awareness of wildlife and their economic value to the country. These initiatives highlight protected areas to the mainstream media and encourage domestic tourism. Second, parades around the country, intramural sports teams, as well as public lectures, community and school events are held to mobilize additional conservation awareness. Lastly, we discuss the role of strategic communication through media frames by the national newspapers in promoting the importance of wildlife conservation. These initiatives have likely led to the demonstrated increase in domestic tourism to national parks over the past decade and increase in support for wildlife by the Ugandan public.
