Conservation and management issues of Prespa National Park

The present article describes the human activities inthe area and their changes and trends, given that thecontemporary nature conservation key issues areclosely related to past and present socio-economic andcultural conditions, both within Prespa itself andoutside of it. The liberation of Prespa, a remote andrather socially isolated borderline area, from Ottoman occupation took place in 1912–13. Recentevents in its environmental history have been forestclearings and human depopulation in the Civil War(1944–49), irrigation system construction in the1960s, its discovery by ornithologists in the late1960s, the high emigration rates of 1960–1980, itsdesignation as a National Park in 1974, thedestructive development works of 1984–86 afterGreeces entry to the EEC and the conversion to intensivebean cultivation in the mid 1980s.The human population of ca 7000 at the start of thiscentury suffered an almost 80% decrease after theCivil War. A resettlement in the mid 1950s increasedthe population by 40% but in the 1970s emigrationreduced it to its previous size of around 1500, stillits present size. The extensive and diverse farmingsystems of previous centuries changed gradually afterthe construction of an irrigation network in the1960s, which twenty years later and along withinternational changes in production and economypatterns, made possible the present day domination ofa bean monoculture within irrigated croplands. Thiswas accompanied by increased energy inputs,mechanisation and the use of chemicals.Intensification of agriculture brought increasedincomes which attracted also livestock keepers,resulting in a 56% decrease in numbers of livestockin 1964–1993. Cattle are presently kept for meatproduction only. They graze on the mountains, and nolonger in the meadows around the lakeshore. A localshorthorn breed accounting for 93% of all cattle in1963 declined to less than 18% in 1993. Fishing aimedmainly at carp and Prespa bleak, continues today as inthe past to be a source of supplementary income.Eighty-six per cent of the – mainly oak and beech –forests are State owned and the rest belong to localmunicipalities. The forest area has not changedessentially in the last 40 years, but forest roadshave expanded. Forests provide mainly fuelwood forlocal needs and small quantities of industrial timber.No specific management is conducted to safeguard theconservation values of the forest, the majority ofwhich consists of even aged coppiced stands withlimited value for wildlife. Manufacturing never playedan important role for the economy of the area. Tourismhas increased in the last 20 years, concentratedmainly in summer and spring. Accommodation in thevillages is not yet satisfactory though it hasimproved enormously in recent years. The NationalParks infrastructure for visitors remains poor.Tourist pressure generally is not yet that high toimpact drastically the social and environmentalfabric. In places, hunting, angling and poaching cannegatively affect the target species. The constructionof the irrigation network in the eastern part of LakeMikri Prespa was the most important change to thelandscape and the habitats of Prespa the last 30years. It resulted in the embankment of free-flowingstreams, drainage of wet meadows and dramaticreduction of trees and hedges. In the last 15 years,the reedbeds, no longer burnt or mowed and assisted byincreased nutrient loadings from agricultural runoff,have expanded landward to occupy formerly open,periodically flooded, areas. The above changes inhabitats and land use have brought an impoverishmentof biodiversity which can be seen in the exterminationor the decrease in the numbers of certain plant andbird species.The problems preventing a better management of theNational Park and the perpetuation of its values areinappropriate legislation, the poor degree ofcoordination of the public services, the lack of botha specific National Park Service in Greece and amanagement authority for the Park and the hostileattitude of local people due to their limitedinformation and involvement. The scenic beauty, thewetlands and a number of rare habitats, the diversityof habitats, flora and fauna, the endemic life forms,the rare mammals and the colonial waterbirds, thelocal architecture and the cultural expressions suchas the Byzantine monuments, are the values of Prespathat must be preserved as a whole. The initialconservation efforts aimed at preserving biodiversitybut later it became apparent that not only are humansan inseparable part of the whole, but additionally,several of their extensive activities have contributedsubstantially to the rich biodiversity of the area.Through the prerequisites of keeping a balance betweenprimary and tertiary sector activities and ofrevitalizing the social fabric, the following are thekey management and conservation issues of today: anunequivocal agreement on the values to be preservedand their limits; the formation of a managementauthority; a new realistic protection and land usezoning; the diversification and extensification of allfarming activities; the restoration of the wet meadowhabitats; the ensuring of a high water level and agood water quality for both lakes through tri-lateralcooperation between Greece, Albania and FYROM; and theestablishment of a permanent environmental monitoringscheme.     

What does it take to do successful adaptive management? A case study highlighting Coastal Grassy Woodland restoration at Yanakie Isthmus

The case study of the Yanakie Isthmus Coastal Grassy Woodland Restoration Program, Victoria, Australia, illustrates the steps necessary to deliver a complex, long‐term adaptive management project involving a range of stakeholders at a landscape scale. Perspectives of the land manager, scientist and volunteer help to convey successes and lessons learned.     

Common Property and Conservation: The Potential for Effective Communal Forest Management Within a National Park in Mexico

Common property regimes may contribute to environmental conservationand offer a complementary institutional model to state-run protected areas. The potential conservation value of common property management is of particular significance in Mexico, where a large majority of forests are held communally. Systems of common property management often exist in a context of close institutional overlap with state institutions. This project assessed the function of a common property regime nested within Lagunas de Montebello National Park (PNLM) in Chiapas, Mexico. We documented forest status and analyzed common property forest management institutions following severe fires that threatened forest conservation. Forests managed by the common property regime are less intact than federal forests, yet still moderately conserved, and many attributes necessary for common property management are functional, despite the recent fire crisis. Yet external authorities contest common property management by local institutions, resulting in limited joint management by the national park and the community. Formalization and expansion of de facto cooperation between the federal and community institutions may enhance forest conservation within PNLM.     

Ecotourism and biodiversity conservation in Jozani–Chwaka Bay National Park, Zanzibar

This study is based on a study undertaken to assess how ecotourism has influenced biodiversity conservation in Jozani–Chwaka Bay National Park (JCBNP). It involved two communities surrounding the park, namely Pete and Kitogani. Field data were collected using structured questionnaires, key informant interviews and field observations. Questionnaires were administered to 76 households, whereas key informant interviews were conducted with foresters and JCBNP officials. Data analysis was undertaken using standard statistical methods. Findings from the study show that biodiversity management in the JCBNP has improved considerably after the introduction of ecotourism. The number of endemic colobus monkeys ( Piliocolobus kirkii ) and other rare species has increased. However, this achievement has been attained by restricting surrounding communities from using forest resources without providing alternative sources of livelihood. Findings also show that the benefits from ecotourism do not reach individual households, but the community as whole, in form of various social services. This has caused some resentment among the local people leading to their reluctance to reduce their direct use of ecosystem services available in the JCBNP, claiming that they cannot sustain their livelihood without such services. This has become a major source of conflict between the JCBNP and surrounding communities. Increased awareness and knowledge on biodiversity conservation would be needed for the communities surrounding the park to realize the potential and long-term benefits of ecotourism, and hence the need for their increased involvement in biodiversity management.     

Pemon Perspectives of Fire Management in Canaima National Park,Southeastern Venezuela

Recent research on the ecology of fire has challenged the view that the use of fire by indigenous peoples is detrimental to ecosystems and wildlife in protected areas. However, in Canaima National Park and World Heritage Site in southeastern Venezuela, since 1981 managers have employed a costly fire control program to eliminate savanna burning by the Pemon indigenous people. Here I present the results of the first study on Pemon perspectives of fire management in the park. I show that savanna burning is an important tool in indigenous land management and plays a key role in preventing large catastrophic fires. Pemon knowledge of fire also raises questions about conventional interpretations of environmental change in the park. Lastly, I recommend a fire management policy that seeks to integrate local ecological knowledge. This will require: (a) greater openness from scientists and resource managers to understanding Pemon rationale for the use of fire, (b) clarification among the Pemon themselves of their own views of fire, and (c) research partnerships among scientists, resource managers and the Pemon in order to encourage understanding of Pemon ecological knowledge of fire, and to assess its true impact in the Canaima National Park.     

Measuring impact of protected area management interventions: current and future use of the Global Database of Protected Area Management Effectiveness

Protected areas (PAs) are at the forefront of conservation efforts, and yet despite considerable progress towards the global target of having 17% of the world''s land area within protected areas by 2020, biodiversity continues to decline. The discrepancy between increasing PA coverage and negative biodiversity trends has resulted in renewed efforts to enhance PA effectiveness. The global conservation community has conducted thousands of assessments of protected area management effectiveness (PAME), and interest in the use of these data to help measure the conservation impact of PA management interventions is high. Here, we summarize the status of PAME assessment, review the published evidence for a link between PAME assessment results and the conservation impacts of PAs, and discuss the limitations and future use of PAME data in measuring the impact of PA management interventions on conservation outcomes. We conclude that PAME data, while designed as a tool for local adaptive management, may also help to provide insights into the impact of PA management interventions from the local-to-global scale. However, the subjective and ordinal characteristics of the data present significant limitations for their application in rigorous scientific impact evaluations, a problem that should be recognized and mitigated where possible.     

Murray Catchment habitat restoration: Lessons from landscape‐level research and monitoring

Native vegetation restoration and conservation works have been ongoing for three decades in the South West Slopes Bioregion of NSW's Murray Catchment. Monitoring of extensive areas of protected remnants and revegetation undertaken through a major partnership between ANU researchers and the Murray CMA shows early benefits of restoration efforts to biodiversity and helps to refine future efforts.     

Holocene vertebrate fossils aid the management and restoration of Australian ecosystems

European‐settlement‐related impacts over the past 200 years pose many challenges for the conservation and restoration of Australia's ecosystems. Landscape modification, associated habitat loss and the introduction of exotic species have caused the extinction and mainland extirpation of numerous vertebrates. This process happened so quickly that many species became locally or functionally extinct before their presence was documented. A growing body of research on Holocene fossil accumulations is providing insights into the composition and biogeography of Australian ecosystems prior to European settlement. This review explores the similarities between palaeo‐ and neo‐ecology and how Holocene (last 10,000 years) assemblages can be used by neo‐ecologists, conservation managers and policy makers to identify and fill gaps in knowledge and contribute to the management and restoration of Australia's degraded ecosystems.     

Making parks make a difference: poor alignment of policy,planning and management with protected-area impact,and ways forward

Policy and practice around protected areas are poorly aligned with the basic purpose of protection, which is to make a difference. The difference made by protected areas is their impact, defined in program evaluation as the outcomes arising from protection relative to the counterfactual of no protection or a different form of protection. Although impact evaluation of programs is well established in fields such as medicine, education and development aid, it is rare in nature conservation. We show that the present weak alignment with impact of policy targets and operational objectives for protected areas involves a great risk: targets and objectives can be achieved while making little difference to the conservation of biodiversity. We also review potential ways of increasing the difference made by protected areas, finding a poor evidence base for the use of planning and management ‘levers’ to better achieve impact. We propose a dual strategy for making protected areas more effective in their basic role of saving nature, outlining ways of developing targets and objectives focused on impact while also improving the evidence for effective planning and management.     

Animal Preferences and Acceptability of Wildlife Management Actions around Serengeti National Park, Tanzania

Wildlife management policies are often based on expert perceptions of the ecological importance of certain species and poorly informed perceptions of how public attitudes toward management are formed. Little is known about why preferences vary greatly and how this affects support for management actions. This paper explores preferences for a range of wildlife species among a sample of the rural population adjacent to Serengeti National Park in Tanzania. We also examine the degree of acceptance for alternative management interventions when potentially dangerous animals pose different levels of problems to human beings, and the extent to which these attitudes are related to species preferences. Gender has a significant effect on species preferences. Men like most species better than women. Age has no significant effect, but level of education affects preference level for some species. Species preferences have a positive effect on support for management intervention when dangerous animals cause small or moderate problems to humans, i.e. there is a higher degree of acceptance of problems caused by animals that are well liked. In situations where human life is threatened, species preferences have no effect on preferred management actions. Appreciation of animals is a combination of functional, consumptive and cultural dimensions, and there is no simple link between species preferences and attitudes toward management actions. The local context and concrete experience with wildlife encounters is more important for shaping normative beliefs like attitudes towards management actions than global wildlife attitudes.
