Due to long-term human activity interference,the Hainan Tropical Rainforest National Park(HTRNP)of China has experienced ecological problems such as habitat fragmentation and biodiversity loss,and with the expanding scope and intensity of human activity impact,the regional ecological security is facing serious challenges.A scientific assessment of the interrelationship between human activity intensity and habitat quality in the HTRNP is a prerequisite for achieving effective management of ecological disturbances caused by human activities and can also provide scientific strategies for the sustainable development of the region.Based on the land use change data in 2000,2010,and 2020,the spatial and temporal variations and the relationship between habitat quality(HQ)and human activity intensity(HAI)in the HTRNP were explored using the integrated valuation of ecosystem services and trade-offs(InVEST)model.System dynamics and land use simulation models were also combined to conduct multi-scenario simulations of their relationships.The results showed that during 2000–2020,the habitat quality of the HTRNP improved,the intensity of human activities decreased each year,and there was a negative correlation between the two.Second,the system dynamic model could be well coupled with the land use simulation model by combining socio-economic and natural factors.The simulation scenarios of the coupling model showed that the harmonious development(HD)scenario is effective in curbing the increasing trend of human activity intensity and decreasing trend of habitat quality,with a weaker trade-off between the two compared with the baseline development(BD)and investment priority oriented(IPO)scenarios.To maintain the authenticity and integrity of the HTRNP,effective measures such as ecological corridor construction,ecological restoration,and the implementation of ecological compensation policies need to be strengthened. 展开更多

Vegetation resilience(VR),providing an objective measure of ecosystem health,has received considerable attention,however,there is still limited understanding of whether the dominant factors differ across different climate zones.We took the three national parks(Hainan Tropical Rainforest National Park,HTR;Wuyishan National Park,WYS;and Northeast Tiger and Leopard National Park,NTL)of China with less human interference as cases,which are distributed in different climatic zones,including tropical,subtropical and temperate monsoon climates,respectively.Then,we employed the probabilistic decay method to explore the spatio-temporal changes in the VR and their natural driving patterns using Geographically Weighted Regression(GWR)model as well.The results revealed that:(1)from 2000 to 2020,the Normalized Difference Vegetation Index(NDVI)of the three national parks fluctuated between 0.800 and 0.960,exhibiting an overall upward trend,with the mean NDVI of NTL(0.923)>HTR(0.899)>WYS(0.823);(2)the positive trend decay time of vegetation exceeded that of negative trend,indicating vegetation gradual recovery of the three national parks since 2012;(3)the VR of HTR was primarily influenced by elevation,aspect,average annual temperature change(AATC),and average annual precipitation change(AAPC);the WYS'VR was mainly affected by elevation,average annual precipitation(AAP),and AAPC;while the terrain factors(elevation and slope)were the main driving factors of VR in NTL;(4)among the main factors influencing the VR changes,the AAPC had the highest proportion in HTR(66.7%),and the AAP occupied the largest area proportion in WYS(80.4%).While in NTL,elevation served as the main driving factor for the VR,encompassing 64.2%of its area.Consequently,our findings indicated that precipitation factors were the main driving force for the VR changes in HTR and WYS national parks,while elevation was the main factors that drove the VR in NTL.Our research has promoted a deeper understanding of the driving mechanism behind the VR. 展开更多

Globally, human activities have a significant impact on the diversity, abundance, and distribution of large mammals in Protected Areas (PAs). These disturbances increase human pressure on biodiversity and species habitats, highlighting the need for conservation. This study aimed to assess the abundance and distribution of large mammals in different habitat types within Nimule National Park (NNP) and understand the impacts of human activities on them. Data on the abundance and distribution of large mammals and their respective habitat types were collected through line transect surveys. Human activity signs were observed and recorded along the transect lines. To estimate the impacts of human activities on the diversity, abundance, and distribution of large mammal species, as well as to identify any significant differences between them and their habitat types, the study utilized the Kruskal Wallis test, Polynomial multiple regressions, and diversity indices. The findings from the Shannon-Weiner and Simpson indices indicated that large mammal species were more diverse inside the park (H’ = 1.136;D = 0.570) compared to the buffer zone (H’ = 0.413;D = 0.171), with 85% (443 out of 510 samples) recorded within Nimule National Park. The species abundance showed a semi-balanced status (0.58). The diversity results among different habitat types revealed that large mammals were more diverse and highly distributed in both open woodlands (244) and dense woodlands (192), while riverine vegetation had the lowest diversity (8). Statistical tests demonstrated a highly significant difference at a 99% confidence interval (p-value = 0.01) between habitat types and identified species of large mammals. Additionally, the results highlighted the high abundance of Uganda kob (274), baboons (141), and warthog (57) across most habitat types, accounting for at least 75% of their distribution. The most prevalent human activities observed were cattle footprints (27%) and cattle dung (14%). Human footprints and tree cutting combined accounted for 9%, indicating the practice of livestock grazing, poaching, encroachment, and fuelwood collection by local communities. However, these activities did not appear to significantly impact the diversity, abundance, and distribution of large mammals in Nimule National Park. Therefore, it is crucial to foster shared responsibilities and engage relevant stakeholders in the management and conservation of large wildlife species. Regular community awareness programs should be implemented to cultivate a sense of ownership. Moreover, it is recommended that a comprehensive survey be conducted on the population status of all mammal species in Nimule National Park, including its surrounding Buffer Zone. Monitoring the impact of human activities on their behavior and habitats using satellite images should also be carried out at least every five to ten years. 展开更多

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. 展开更多

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. 展开更多

Ecosystem responses to climate change,particularly in arid environments,is an understudied topic.This study conducted a spatial analysis of ecosystem responses to short-term variability in temperature,precipitation,and solar radiation in the Qilian Mountains National Park,an arid mountainous region in Northwest China.We collected precipitation and temperature data from the National Science and Technology Infrastructure Platform,solar radiation data from the China Meteorological Forcing Dataset,and vegetation cover remote-sensing data from the Moderate Resolution Imaging Spectroradiometer.We used the vegetation sensitivity index to identify areas sensitive to climate change and to determine which climatic factors were significant in this regard.The findings revealed a high degree of heterogeneity and non-linearity of ecosystem responses to climate change.Four types of heterogeneity were identified:longitude,altitude,ecosystem,and climate disturbance.Furthermore,the characteristics of nonlinear ecosystem responses to climate change included:(1)inconsistency in the controlling climatic factors for the same ecosystems in different geographical settings;(2)the interaction between different climatic factors results in varying weights that affect ecosystem stability and makes them difficult to determine;and(3)the hysteresis effect of vegetation increases the uncertainty of ecosystem responses to climate change.The findings are significant because they highlight the complexity of ecosystem responses to climate change.Furthermore,the identification of areas that are particularly sensitive to climate change and the influencing factors has important implications for predicting and managing the impacts of climate change on ecosystems,which can help protect the stability of ecosystems in the Qilian Mountains National Park. 展开更多

The floristic diversity was carried out from the selected trails while studying wildlife at the Baraiyadhala National Park of Chattogram in Bangladesh from August 2012 to July 2013 and June to October 2017. In total 267 species of plants (Bryophytes three, Pteridophytes 15, Gymnosperm one, Dicotyledons 200 and Monocotyledons 48) belonging to 186 genera and 80 families were recorded, which included 102 (38.20%) species of trees, 84 (31.46%) shrubs, 66 (24.71%) herbs and 15 (5.61%) species of climbers. Overall, Euphorbiaceae (dicotyledon) constituted the largest family in the study area having 12 genera and 18 species, while Cyperaceae (monocotyledon) was the second largest family represented by four genera and 11 species. The single gymnosperm species was Cycas pectinata Griff. (Assam cycas) under Cycadaceae family that naturally grows there. Most of the recorded plants were terrestrial while the others were aquatic or swampy. Among the plants, 210 (78.66%) species were native, of which 152 were Native (wild), 40 Native (wild & cultivated) and 18 Native (cultivated), and the remaining 57 (21.34%) alien species. Of the alien species seven were Alien (wild), ten Alien (wild and cultivated), four Alien (invasive) and 36 Alien (cultivated). Of the 267-plant species, the highest number was medicinally followed by 41 edible, 31 timber, 13 fuel wood and ornamental, 13 fodder, seven ornamental, six species used for domestic purposes and fodder, five edible and medicinal, three vegetables, two vegetables and medicinal, two edible and timber, two timber and leaf, two ornamental and medicinal, one chemical indicator, one ornamental and timber, and the use of 17 rest species was unknown. 展开更多

Natural forest ecosystems play an essential role in the conservation of biodiversity of many plants and animals by providing them with habitat and suitable environments. Studies have shown that biodiversity-protected areas reduce the loss and degradation of natural habitats to various wild species of plants. This study examined the forest resources in five subzones by conducting tree/shrub species inventory to be able to develop an effective forest management plan for the Buffer Zone Forest Reserve for the sustainable conservation of flora and fauna of Nimule National Park. This is with the view to identify the main tree and shrub species;assess the composition, distribution, and abundance of various tree/shrub species;to determine the species diversity as well as the richness of these areas in terms of growth and performance where DBH and heights of trees/shrubs in the circular sample plots were measured. The results revealed the overall mean DBH and H of 13.83 cm and 6.61 m respectively. The highest number of trees was obtained in subzone B followed by D, while the least were found in subzone A. The overall mean tree/shrub density was 0.83 tons/ha. The mean total basal area and volume per hectare were 3252.74 m<sup>2</sup>/ha and 46,540.82 m<sup>3</sup>/ha respectively. The overall species abundance and distribution indicate Combretum spp, Cedrella spp., Grewia mollis, Acacia Sieberiana, Ziziphus abysinica, and Acacia seyal were the most dominant species, with over 12 species richness at the deposition side of the River Nile, 13 species at the western side of the Nile, the Administration site shows only 7 species, the lowland of Mt. Gordon show over 14 different species, whereas over 10 species were found on the top of Mt. Gordon. The overall mean diversity indices and evenness of H’, D, and E depicted 2.507, 0.871, and 0.840 respectively. These results yielded are relatively moderate. Therefore, conservation efforts are very necessary to improve and maintain the quality of vegetation cover. 展开更多

This study deals with the perceptions of indigenous knowledge in the field of conservation and the impact of climate change on biodiversity in the peripheral villages of the Bouba-Ndjidda National Park (PNBN), Department of Mayo-Rey, Cameroon. To this end, 23 out of 70 villages in the study area were selected, for a sample of 368 households surveyed through a questionnaire addressed to the heads of households. Data collection took place from August 27 to December 22, 2022. The results reveal that 70.7% of the population living near the PNBN practice agriculture as their main income-generating activity, followed by livestock (23.3%) and trade (6%). Knowledge in the field of the conservation of natural resources is rooted in occultism through rituals and sacrifices (99.50%) offered to the geniuses of nature and prohibitions on the felling of trees and sacred animals (13.00%). The populations perceive climate change through the variation of the seasons (97.60%), the increase in temperature (84.80%), the reduction in the duration of the rainy seasons (54.60%), the drop in agricultural yield (84.80%) and floods (74.70%). The consequence of these changes on wildlife is the disappearance of animal species such as the Rhinoceros, the Wild Dog, the Cheetah and the Ostrich. In order to cope with climate change, the natives have developed strategies such as the adoption of early crop varieties (maize, millet, soybeans, etc.), the reorganization of the agricultural calendar, the practice of reforestation, extension of field surfaces, the cessation of excessive deforestation and uncontrolled bush fires, the construction of fired brick houses, the practice of irrigation, seasonal migration and occultism. This indigenous knowledge is a perfect adaptation to climate change and makes it possible to better take into account the vision of local populations in the conservation of biodiversity. 展开更多

Tropical rainforests are crucial in maintaining about 70% of the world’s plant and animal biodiversity and are also the highest terrestrial carbon reservoir. This study aimed to determine the tree species composition, structure and carbon stocks of the Deng Deng National Park which is a semi-deciduous tropical forest (plots 1 and 2 and the transition zone to the savannah (plot 3). Plots demarcation and enumeration followed standard protocols for permanent monitoring plots. The inventory of tree species ≥ 2 cm revealed a total of 5523 individuals of 64 species in 53 genera belonging to 26 families with plot 2 having the highest (2135 individuals/ha) and plot 3 the least (1291 individuals/ha). Tabernaemontana crassa was the most important tree species in the tropical forest and Lecythis idatimon in the savannah. Basal area was highest in the tropical forest and least in the savannah. The diameter distribution of trees in all forest types displayed a reverse J-pattern. Aboveground biomass was highest in the tropical forest (530.2 ± 66.4 t·C/ha) and least in the savannah (184.3 ± 20.1 t·C/ha). The carbon stock of the above ground biomass was twice as much as that of the below ground biomass, soil organic matter and litter. The total carbon stock estimated in all pools was 278.75 t·C/ha. The study site was poor in plant diversity, biomass and carbon stock, indicating a disturbed site with the absence of large trees and undergoing natural regeneration. This underlines an urgent need for efficient restoration management practices. 展开更多

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. 展开更多

This study estimated tourists’Willingness to Pay(WTP)per day for recreation services in Nyerere National Park(NNP)and compared these values with daily travel costs that are incurred by tourists to visit NNP in order to inform whether recreation resources in the park are overvalued or undervalued.The study revealed that tourists’WTP per day for recreation services was estimated at$237.4 and$1521 for resident and non-resident tourists,respectively.The estimated tourists’WTP values exceed the daily travel costs currently incurred by tourists,which are$201.04 and$1517.97 for resident and non-resident tourists,respectively.This indicates that tourists are willing to spend more to enjoy recreation services in NNP,which signifies that recreation resources in NNP are slightly undervalued.In addi­tion,the findings disclosed that the largest share of tourist daily travel expenses is allocated to transportation services,and very little is paid to the park as a conservation fee.It was revealed that out of the daily travel expenses incurred by non-resident and resident tourists,only 4.62%and 2.23%are respectively paid directly to NNP as conservation fees.This study considers that allocation is not very fair;thus,NNP,in collaboration with TANAPA,needs to adjust the current entrance or conservation fee and reduce the transportation costs charged by tourist companies.The travel costs incurred by tourists,age,education,monthly income,site visited,substitute site,and quality of park were identified as significant factors in influencing tourists’WTP for recreation services in NNP.Thus,policies oriented to reduce tour­ists’transportation costs and improve the quality of national parks would attract more tourists to NNP. 展开更多

[Objective] This study aimed to investigate the fungi in Wula Mountain National Forest Park. [Method] More than 180 fungal specimens were collected from Wula Mountain National Forest Park from 2009 to 2012 for primarily studying the fungal species diversity. [Results] According to the classification system presented by Ainsworth et al. and with reference to the China catalogue of Macrofungi in species diversity catalogue of Fungi at Wula Mountain National Forest Park was written, involving in 80 species belonging to 43 genera, 22 families, 5 orders and 2 classes in the Basidiomycotina, and 6 species belonging to 2 genera, 2 families, 2 orders and2 classes in Ascomycotina, totally from 86 species, 45 genera, 7 orders, 24 families and 2 subdivisions. Among them, 49 species were edible and 22 species were medicinal, and 18 species were both edible and medicinal, and 7 species were poisonous, and 32 species were wood-rotting, and 5 species were mycorrhizal fungi,and 3 species were newly-recorded ones in Inner Mongolia. [Conclusion] There are still some specimens that have not been identified yet because of lack of literature,thus requiring further study for supplement. 展开更多

The evaluation of landscape resources is the basis of tourism development. The traditional aesthetic value assessment of forest landscape mainly focuses on the visual perception, but the auditory perception is usually ignored. In fact, the esthetics artistic conception is not complete without each sense. With a case study on the National Forestry Park of Mount Sanzhualun in Jiangxi Province, the investigation and analysis of the soundscape resources are made in this research. The forest soundscape resources are classified into six types, mainly including water soundscape, rain soundscape, birds' soundscape, leaf soundscape, insects' soundscape and wind soundscape. Furthermore, the concept, content and rule of forest soundscape resources are defined so as to provide significant references for the more advantageous development, utilization and management of the forest landscape resources. 展开更多
