Hunting for a Living: Wildlife Trade,Rural Livelihoods and Declining Wildlife in the Hkakaborazi National Park,North Myanmar

Hunting is a threat to wildlife within the Hkakaborazi National Park in north Myanmar. We used questionnaire surveys to obtain data on variables such as commonly targeted species, prices of traded wildlife, reasons for hunting and the relative importance of livelihood sources. We examine (a) the significance of hunting and trade for livelihoods and explore (b) the impacts of hunting on targeted species. Ninety per cent of trade records (n = 803) was constituted by seven species commonly targeted by hunters (serow, red goral, muntjac, bear, Assamese macaque, black musk deer and takin). Commercially valuable species previously targeted by hunters (tiger, otter, pangolin) appear to be completely absent from current harvest records and potentially in decline. Although farming is the predominant occupation, hunting (driven by trade) represents a significantly higher source of income than other livelihood activities. Management recommendations include increased investment in enforcement, education and outreach, small livestock development, improved crop productivity, demarcation of no-take areas for wildlife and biological monitoring of targeted species.     

The environmental history of Chatthin Wildlife Sanctuary, a protected area in Myanmar (Burma)

We reconstructed the history of Chatthin Wildlife Sanctuary (CWS) to understand how social and economic events, and policy changes affected the sanctuary's condition. We surveyed 25 villages surrounding CWS to evaluate past and present ecological conditions, compare the results with historical accounts and identify causal relationships. During the first half of the 20th century, the primary threat was the government's reduction of old growth forest to supply fuel wood for the British-built railway. The railroad opened the area to colonization, but the villagers' impact on timber and wildlife was low. From 1945 to 1988, villagers became the primary force of landscape degradation. The post-war windfall of firearms increased hunting pressure, and populations of large mammal started to decline. With the economic decline of the 1970s and 1980s, the community's demand for game and forest products intensified, and the large mammal fauna was reduced from eleven to four species. From 1988-2003, the forests surrounding the sanctuary were fragmented and degraded. The absence of large predators rendered the park safe for livestock, and the combined effects of grazing and removal of forest products seriously degraded habitat within CWS. Major threats to CWS during the past two decades have resulted from land use decisions in which government-planned economic enterprises caused encroachment by villagers. Stabilization and recovery of this sanctuary will require management compatible with human needs, including expanded buffer zones, better core area protection, community forestry projects, and probably relocation of villages within the park.     

Enforcement Authority and Vegetation Change at Kumbhalgarh Wildlife Sanctuary,Rajasthan, India

Land cover change in protected areas is often associated with human use, especially illicit extraction, but the direction and spatial distribution of such effects and their drivers are poorly understood. We analyze and explain the spatial distribution of vegetation change at the Kumbhalgarh Wildlife Sanctuary in the Aravalli range of Rajasthan, India using remotely sensed data and observation of conservation institutions. Two satellite images are examined in time series over the 13 years following the founding of the sanctuary through a cross-tabulation technique of dominant classes of vegetation density. The resulting change trajectories are compared for their relative distance to high-traffic forest entrance points for local users. The results show 28% of the study area undergoing change, though in multiple trajectories, with both increasing and decreasing density of vegetation in discrete patches. Areas of change are shown to be closer to entrance points than areas experiencing no change. The patchiness of change results from complex issues in local enforcement authority for middle and lower-level officials in Forest Department bureaucracy, leading to further questions about the efficacy and impact of use restrictions in Protected Areas.     

Endorsement of Ethnomedicinal Knowledge Towards Conservation in the Context of Changing Socio-Economic and Cultural Values of Traditional Communities Around Binsar Wildlife Sanctuary in Uttarakhand, India

The study of the interrelationship between ethnomedicinal knowledge and socio-cultural values needs to be studied mainly for the simple reason that culture is not only the ethical imperative for development, it is also the condition of its sustainability; for their exists a symbiotic relationship between habitats and cultures. The traditional communities around Binsar Wildlife Sanctuary of Uttarakhand state in India have a rich local health care tradition, which has been in practice for the past hundreds of years. The present study documents the Ethnomedicinal uses of 54 medicinal and aromatic plants (MAPs) along with their botanical and vernacular names, family, habit, habitat, threat status, collection season, purpose of collection, quantity, conservation practices, market potential and part(s) used in traditional health care system. The documented species belonging to 38 families have been used to cure more than 47 different kinds of ailments. These MAPs collected from the wild in a particular season and used as per the method prescribed by traditional herbal healers (Vaidyas) that provide effective results. Perception of local people during field trips based on socio-demographic characters showed them to prefer herbal system of treatments and they understood the status of traditional health care systems in the region. The study reveals that approximately 70 % population of the study area depend on herbal systems of treatments and preferred to visit Vaidyas for curing a variety of ailments because the traditional system of medicine is one of the most important prevailing systems in the region where modern health care facilities are rare or in very poor conditions. The organic cultivation practices of selected MAPs were demonstrated to rural inhabitants through capacity building training program and participatory action research framework approaches for sustainability and enhancement of livelihood security. A series of workshops and village level meetings on traditional health care systems were organized and forming/registered a strong association of Vaidyas for making their traditional system of health care more practical and effective. The study emphasizes the potentials of the ethnomedicinal research, conservation practices, socio-cultural and religious ethics for promoting traditional plants based treatments and also the need to document the indigenous knowledge for scientific validation before its industrial application.     

Depleting Fish Resources,Declining Fishing Communities,and the State Revitalization Project in Korea

This paper reviews recent declines in fish resources and fishing communities in Korea, evaluates major factors of declines, and examines a subsequent community-based revitalization project. Factors leading to depleting fish resources include global regulations, technological advances in fishing, national economic development policies, land reclamation projects, and pollution. The negative economic and societal impact of depleting fish resources is addressed using demographic and income levels of the communities. In response, the state initiated revitalization projects and invested in local fishing cooperatives promoting community-based management. The result has been less than effective as it led to mismanagement of investment and created an attitude of dependence on the government for financial assistance.     

Water and the potential for social instability: Livelihoods, migration and the building of society

In much of the Third World, access to secure water for irrigation, particularly groundwater, reduces vulnerability, stabilizes livelihoods,alleviates poverty and 'entitles' populations to education and other forms of capital accumulation. Water resource development can, as a result, be used as a key tool for addressing the social roots of instability. The reverse is also true — problems such as groundwater overdraft contribute to poverty and are often at the root of forced migration and the creation of underemployed and unstable displaced populations. Water is fundamental to regional as well as local security.
The benefits of water resource development and the risks associated with unsustainable use patterns are particularly critical in arid regions. Patterns of water use that are unsustainable can play a positive role in the transition of populations from nomadic or migratory to stable communities, where people have access to education and asset accumulation. The exit is, however, as important as the entry. In many regions, the majority of the population now need to make the transition from agriculture to non–agricultural livelihoods. Many people, particularly the wealthy, may already be doing this. Understanding and enabling transition represents one of the most important policy challenges for coming decades.
Using examples from India, Yemen, Saudi Arabia and other countries, this article documents some of the connections between water and security and clarifies the importance of effective solutions to water problems and to social transition in arid regions.     

A Dynamic Simulation Model of Land-Use, Population, and Rural Livelihoods in the Central Rift Valley of Ethiopia

The dynamic interactions between society and land resources have to be taken into account when planning and managing natural resources. A computer model, using STELLA software, was developed through active participation of purposively selected farm households from different wealth groups, age groups and gender within a rural community and some members of Kebelle council. The aim of the modeling was to study the perceived changes in land-use, population and livelihoods over the next 30 years and to improve our understanding of the interactions among them. The modeling output is characterized by rapid population growth, declining farm size and household incomes, deteriorating woody vegetation cover and worsening land degradation if current conditions remain. However, through integrated intervention strategies (including forest increase, micro-finance, family planning, health and education) the woody vegetation cover is likely to increase in the landscape, population growth is likely to slow down and households’ income is likely to improve. A validation assessment of the simulation model based on historical data on land-use and population from 1973 to 2006 showed that the model is relatively robust. We conclude that as a supporting tool, the simulation model can contribute to the decision making process.     

Destruction of Forests and Wildlife in the Kashmir Wilderness

Much of the forest wealth on the plains and in the hilly areas of India has been foolishly destroyed, and the rich heritage of wildlife has been slaughtered mostly for only temporary gain. The wanton axing of the larger indigenous trees and the uprooting of other floristic elements in the hills and on the lower slopes of the mountains, gradually impoverishes them, and may be followed by erosion that ultimately leaves the slopes barren. These alarming threats to the chir (Pinus roxburghii) and fir (Abies pindrow) forests of Kashmir will have disastrous consequences. Once densely-forested, the mountain slopes in Kashmir have become largely naked through too-heavy tapping and cutting of the trees; with concomitant landslides, frequent floods, and loss of fertile topsoil. Unfortunately, the people living in the areas of the chir and fir trees, do not play a proper part in their protection, and the last two decades have witnessed, year by year, the rapid march of urbanization and manifold destructive activities which have taken a heavy toll on these precious species. Urgent conservation measures are essential to preserve these endangered trees in Kashmir.     

Biodiversity Conservation,Ecosystem Services and Livelihoods in Tropical Landscapes: Towards a Common Agenda

Trade-offs between ecosystem conservation and agricultural production can more easily be addressed by shifting the view from the plot scale to the scale of the landscape and integrating biodiversity friendly land use systems into development strategies. The provision of ecosystem services such as watershed protection and carbon sequestration by natural and complex agro-ecosystems can play an important role in making such integrated landscape approaches viable. This special issue brings together papers that were presented at a symposium on agroforestry and landscape scale conservation at the Second World Agroforestry Congress in Nairobi in August 2009. It is divided into two sections focusing on: (1) the biological mechanisms and implications of landscape scale conservation strategies as influenced by land use, especially agroforestry; and (2) the economic drivers and public policies that determine to a large extent the success of agroforestry-based landscape conservation strategies. The contributions provide evidence both for the potential and limitations of agroforestry in landscape scale conservation and development strategies and highlight the importance of economic incentives and policies to promote integrated landscape solutions. This introductory paper summarizes and discusses the contributions and concludes with policy recommendations and research needs.     

A Survey of Strategies Adopted by UK Wildlife Trusts in the Promotion of Gardening for Wildlife

With the decline of wildlife due to, among other things, agricultural intensification, gardening for wildlife has an increasingly recognized role in the conservation of biodiversity and habitats. The United Kingdom (UK) Wildlife Trusts have a key role in the promotion of awareness and best practice of wildlife gardening. In spring 2001, a survey of all 46 United Kingdom County Wildlife Trusts was carried out, focussing on their level of awareness of the issue, whether they actively promoted it, and what literature they employ, and whether they form partnerships in implementing this project.The survey achieved an 83 percent reply rate. The Trusts carried out a wide variety of promotional activities, although its importance as an issue varied from Trust to Trust. Some Trusts have developed excellent promotional literature and strategies, but there could be a greater degree of sharing of ideas and cross fertilization to avoid reinventing the wheel. Few Trusts had developed partnerships, although local government was the most frequent partner.     

Wildlife resources in creating the new Alaskan Parks and preserves

Legislation settling the Alaska Native Lands Claims also resulted in the establishment of ten new parks and preserves in Alaska. This settlement was the result of a long and often bitter legislative struggle between pro- and antidevelopment groups. The planning history of the Wrangell-St. Elias National Park and Preserve is used as a case example of this debate. One particular source of conflict was the curtailment of sport hunting that would result under national park classification. A preserve classification was introduced to resolve this conflict. Data on wildlife resources and sport hunting were instrumental in defining the areas so classified.     

Changes in Determinants of Deforestation and Forest Degradation in Popa Mountain Park, Central Myanmar

Implementing effective conservation requires an understanding of factors affecting deforestation and forest degradation. Previous studies have investigated factors affecting deforestation, while few studies have examined the determinants of both of deforestation and forest degradation for more than one period. To address this gap, this study examined factors influencing deforestation and forest degradation during 1989–2000 and 2000–2005 in the Popa Mountain Park, Myanmar. We applied multinomial logistic regression (MNL) using land cover maps derived from Landsat images as the dependent variables as well as spatial and biophysical factors as the independent variables. The MNL models revealed influences of the determinants on deforestation and forest degradation changes over time. For example, during 1989–2000, deforestation from closed forest was positively correlated to the distance from the park boundary and was negatively correlated with distance from villages, roads, the park circular road, slope, western aspect and elevation. On the other hand, during 2000–2005, deforestation of closed forest was positively correlated with distance from villages, roads, the park circular road, slope and western aspect, and negatively correlated with distance from the park boundary and elevation. Similar scenarios were observed for the deforestation of open forest and forest degradation of closed forest. The study also found most of the determinants influenced deforestation and forest degradation differently. The changes in determinants of deforestation and forest degradation over time might be attributable to the general decrease in resource availability and to the effect of conservation measures conducted by the park.     

Wildlife conservation in Nigeria: Problems and strategies

Summary This paper draws the attention to the major threats to nature conservation in Nigeria, and reviews critically the measures adopted for the protection of wildlife. The major problems include habitat degradation (through uncontrolled logging, agricultural projects, industrial plantations, highway and urban development, and exploitation for fuelwood), over-hunting and poachingSteps taken so far to protect wildlife include the creation of one national park and eighteen game reserves, enactment of wildlife laws, signing of international treaties, and manpower development. These measures have however failed to produce the desired effect owing largely to public apathy, low level of funding, inadequate game laws and weak enforcement of existing legal provisions.It is suggested that the Federal Government should intervene more positively in favour of conservation by creating more national parks and assuming joint responsibility with the states for formulating wildlife laws. Furthermore, the role of non-governmental organizations in influencing conservation policies and mobilizing public opinion will be crucial in the difficult years ahead.Dr. P. A.

Control of Tamarix in the Western United States: Implications for Water Salvage, Wildlife Use, and Riparian Restoration

Non-native shrub species in the genus Tamarix (saltcedar, tamarisk) have colonized hundreds of thousands of hectares of floodplains, reservoir margins, and other wetlands in western North America. Many resource managers seek to reduce saltcedar abundance and control its spread to increase the flow of water in streams that might otherwise be lost to evapotranspiration, to restore native riparian (streamside) vegetation, and to improve wildlife habitat. However, increased water yield might not always occur and has been substantially lower than expected in water salvage experiments, the potential for successful revegetation is variable, and not all wildlife taxa clearly prefer native plant habitats over saltcedar. As a result, there is considerable debate surrounding saltcedar control efforts. We review the literature on saltcedar control, water use, wildlife use, and riparian restoration to provide resource managers, researchers, and policy-makers with a balanced summary of the state of the science. To best ensure that the desired outcomes of removal programs are met, scientists and resource managers should use existing information and methodologies to carefully select and prioritize sites for removal, apply the most appropriate and cost-effective control methods, and then rigorously monitor control efficacy, revegetation success, water yield changes, and wildlife use.     

Bird Use of Restoration and Reference Marshes Within the Barn Island Wildlife Management Area, Stonington, Connecticut, USA

/ Tidal marshes have been actively restored in Connecticut for nearly 20 years, but evaluations of these projects are typically based solely on observations of vegetation change. A formerly impounded valley marsh at the Barn Island Wildlife Management Area is a notable exception; previous research at this site has also included assessments of primary productivity, macroinvertebrates, and use by fishes. To determine the effects of marsh restoration on higher trophic levels, we monitored bird use at five sites within the Barn Island complex, including both restoration and reference marshes. Use by summer bird populations within fixed plots was monitored over two years at all sites. Our principal focus was Impoundment One, a previously impounded valley marsh reopened to full tidal exchange in 1982. This restoration site supported a greater abundance of wetland birds than our other sites, indicating that it is at least equivalent to reference marshes within the same system for this ecological function. Moreover, the species richness of birds and their frequency of occurrence at Impoundment One was greater than at 11 other estuarine marshes in southeastern Connecticut surveyed in a related investigation. A second marsh, under restoration for approximately ten years, appears to be developing in a similar fashion. These results complement previous studies on vegetation, macroinvertebrates, and fish use in this system to show that, over time, the reintroduction of tidal flooding can effectively restore important ecological functions to previously impounded tidal marshes.KEY WORDS: Estuarine; Tidal marsh; Wetland birds; Restoration     

Contaminants evaluation of Marais des Cygnes National Wildlife Refuge in Kansas and Missouri,USA

At the new Marais des Cygnes National Wildlife Refuge in Linn County, Kansas, and Bates County, Missouri, USA, we evaluated long-lived contaminants before acquisition of the land for the refuge. We sampled sediments at 16 locations and fish at seven locations. The samples were analyzed for metals and for chlorinated hydrocarbon compounds. Selected sediment samples also were analyzed for aliphatic hydrocarbons. Arsenic concentrations in sediment samples from six locations were elevated compared to US norms, but arsenic was not detected in any fish composite. Mercury concentrations in largemouth bass from two locations were comparable to the 85th percentile concentrations in nationwide fish collections. Most sediment concentrations of other metals were unlikely to have detrimental effects on biota. No chlorinated hydrocarbons were detected in any sediment sample. Chlordane compound concentrations in fish composites from two sites at the eastern end of the sampling area were 0.127 and 0.228 μg/g wet weight, respectively, which are high enough to cause concern. Most aliphatic hydrocarbons detected were found at low concentrations and probably were natural in origin. We concluded that there are no serious contaminants concerns within the project area, but past use of arsenical pesticides may mean a legacy of elevated soil arsenic levels in parts of the area and some use of banned pesticides such as chlordane and DDT likely is still occurring near the refuge.     

Fishers,Farms, and Forests in Eastern North America

The fisher (Martes pennanti) has recently recovered from historic extirpations across much of its geographic range. There are at least five explanations for the recovery of the fisher, including changes in the amount of habitat, the suitability of habitat, trapping pressure, societal attitudes toward predators, and climate. We evaluated a recovering fisher population in Ontario to test two conditions we viewed as necessary to support the hypothesis that fisher populations have increased due to an increase in the amount of forested land. First, we tested whether the amount of forested land has increased. Second, we tested whether contemporary fisher abundance (and therefore habitat quality) was related to the amount of forest. Topographic maps showed that the proportion of forested land in the study area had increased by 1.9% per decade since 1934 and 3.3% per decade since 1959, likely as a result of land conversion from agricultural uses. Overall the proportion of the study area that was forested increased from 29% to 40% during 1934 to 1995. Census data from the region indicated that there had been a decline in the amount of land area being farmed during the last 50 years. Recent livetrapping data showed that fisher abundance was positively related to the proportion of landscapes that were forested. Based on our results, we could not reject the hypothesis that an increase in the amount of forested land has contributed to the recovery of fisher populations.
