Generation of Priority Research Questions to Inform Conservation Policy and Management at a National Level

Abstract: Integrating knowledge from across the natural and social sciences is necessary to effectively address societal tradeoffs between human use of biological diversity and its preservation. Collaborative processes can change the ways decision makers think about scientific evidence, enhance levels of mutual trust and credibility, and advance the conservation policy discourse. Canada has responsibility for a large fraction of some major ecosystems, such as boreal forests, Arctic tundra, wetlands, and temperate and Arctic oceans. Stressors to biological diversity within these ecosystems arise from activities of the country's resource‐based economy, as well as external drivers of environmental change. Effective management is complicated by incongruence between ecological and political boundaries and conflicting perspectives on social and economic goals. Many knowledge gaps about stressors and their management might be reduced through targeted, timely research. We identify 40 questions that, if addressed or answered, would advance research that has a high probability of supporting development of effective policies and management strategies for species, ecosystems, and ecological processes in Canada. A total of 396 candidate questions drawn from natural and social science disciplines were contributed by individuals with diverse organizational affiliations. These were collaboratively winnowed to 40 by our team of collaborators. The questions emphasize understanding ecosystems, the effects and mitigation of climate change, coordinating governance and management efforts across multiple jurisdictions, and examining relations between conservation policy and the social and economic well‐being of Aboriginal peoples. The questions we identified provide potential links between evidence from the conservation sciences and formulation of policies for conservation and resource management. Our collaborative process of communication and engagement between scientists and decision makers for generating and prioritizing research questions at a national level could be a model for similar efforts beyond Canada.     

Air Quality Management: Participatory Ranking of Control Measures and Conflict Analysis

The ranking of air quality control measures according to a number of evaluation criteria and with the participation of a large number of interested publics is demonstrated. A pilot study for the South Coast Air Quality Management District of California serves as the reference point. Several methodological considerations are addressed, such as: (a) the enhancement of criterion priorities to account for the variability among the performance of the control measures when incommensurable impact levels are applied: (b) the derivation of alternative rankings according to the priorities of potential coalitions; (c) the assessment of the potential acceptability of a collective ranking given the degree of solidarity among participants with similar interest affiliations; and (b) the assessment of the extent to which the performance of specific control measures may override priority differences and lead to insignificant ranking differences.     

Global gap analysis of cactus species and priority sites for their conservation

Knowing how much biodiversity is captured by protected areas (PAs) is important to meeting country commitments to international conservation agreements, such as the Convention on Biological Diversity, and analyzing gaps in species coverage by PAs contributes greatly to improved locating of new PAs and conservation of species. Regardless of their importance, global gap analyses have been conducted only for a few taxonomic groups (e.g., mangroves, corals, amphibians, birds, mammals). We conducted the first global gap analysis for a complete specious plant group, the highly threatened Cactaceae. Using geographic distribution data of 1438 cactus species, we assessed how well the current PA network represents them. We also systematically identified priority areas for conservation of cactus species that met and failed to meet conservation targets accounting for their conservation status. There were 261 species with no coverage by PAs (gap species). A greater percentage of cacti species (18%) lacked protection than mammals (9.7%) and birds (5.6%), and also a greater percentage of threatened cacti species (32%) were outside protected areas than amphibians (26.5%), birds (19.9%), or mammals (16%). The top 17% of the landscape that best captured covered species represented on average 52.9% of species ranges. The priority areas for gap species and the unprotected portion of the ranges of species that only partially met their conservation target (i.e., partial gap) captured on average 75.2% of their ranges, of which 100 were threatened gap species. These findings and knowledge of the threats affecting species provide information that can be used to improve planning for cacti conservation and highlight the importance of assessing the representation of major groups, such as plants, in PAs to determining the performance of the current PA network.     

National Red Listing Beyond the 2010 Target

Abstract: Following creation of the 2010 Biodiversity Target under the Convention on Biological Diversity and adoption of the United Nations Millennium Development Goals, information on status and trends of biodiversity at the national level has become increasingly important to both science and policy. National red lists (NRLs) of threatened species may provide suitable data for reporting on progress toward these goals and for informing national conservation priority setting. This information will also become increasingly important for developing species‐ and ecosystem‐based strategies for climate change adaptation. We conducted a thorough global review of NRLs in 109 countries and analyzed gaps in NRL coverage in terms of geography and taxonomy to determine priority regions and taxonomic groups for further investment. We then examined correlations between the NRL data set and gross domestic product (GDP) and vertebrate species richness. The largest geographic gap was in Oceania, followed by middle Africa, the Caribbean, and western Africa, whereas the largest taxonomic gaps were for invertebrates, fungi, and lichens. The comprehensiveness of NRL coverage within a given country was positively correlated with GDP and negatively correlated with total vertebrate richness and threatened vertebrate richness. This supports the assertion that regions with the greatest and most vulnerable biodiversity receive the least conservation attention and indicates that financial resources may be an integral limitation. To improve coverage of NRLs, we propose a combination of projects that target underrepresented taxa or regions and projects that provide the means for countries to create or update NRLs on their own. We recommend improvements in knowledge transfer within and across regions as a priority for future investment.     

Benefits of Studies of Overwintering Birds for Understanding Resident Bird Ecology and Promoting Development of Conservation Capacity

Abstract:  Funding of ecological research and monitoring of Neotropical migratory birds on their overwintering grounds has benefited both migratory and permanent-resident species. Using examples from our work in Puerto Rico and the Dominican Republic, we demonstrate that ecological research of overwintering migrants often provides information about the ecology and demography of little-known tropical resident birds. Critically important long-term monitoring in Puerto Rico with a focus on winter residents has provided information on the relationships between annual rainfall and fluctuations in resident bird populations and survival rates. It also has alerted local biologists to declines in resident bird populations, including a decline apparently driven by the entry of a brood parasite. But migrant-focused research may also have had an underappreciated effect on the development of conservation capacity and conservation efforts in host countries. Investments in research on Neotropical migrants overwintering on Hispaniola have resulted in a huge increase in field training of students and wildlife professionals, promoted conservation awareness at local and national levels, played an important role in the growth and professionalization of key environmental organizations, spawned a growing ecotourism industry for bird-watching, and driven national park management planning and conservation efforts for all bird species. We encourage funding organizations and agencies to consider the broader impacts of funding migratory-bird research and monitoring efforts, and we encourage researchers in the tropics to use protocols that provide the most information about all the birds that use the study areas involved and to be aware of important opportunities that they may have to build capacity in host countries.     

How Broad-Scale Studies of Patterns and Processes Can Serve to Guide Conservation Planning in Africa

Abstract:  Analysis of large-scale biodiversity patterns can uncover general relationships and problems that need to be taken into account when conservation strategies are developed. Nevertheless, these large-scale patterns need to be supplemented with information from local studies that can identify specific problems and determine how the land can be divided between conservation and development interests. I analyzed biodiversity patterns at three different scales to show how various scales of research contributed to conservation planning. A gap analysis for all of sub-Saharan Africa revealed that the network of wildlife reserves provides insufficient protection of narrowly endemic and threatened species, mainly because such species are aggregated in certain areas with dense human populations. A more fine-grained analysis of the distribution of forest birds of eastern Africa generally confirmed the results obtained with coarse-scale data and added precision by identifying forest tracts where conservation actions should be concentrated. Detailed local distribution data for one of the prioritized areas, the Uluguru Mountains in Tanzania, suggest that the actions to halt the loss of biodiversity should be concentrated in the submontane zone, immediately adjacent to densely populated areas. To achieve conservation on the ground, these general planning tools must be supplemented with other kinds of research concerning land-use and local knowledge and with approaches that promote more sustainable development. Different types of institutions will be needed for these different tasks, but it is essential that researchers maintain a dialogue with planners in this area .     

“半个地球”愿景下的保护地识别——基于全球主要优先保护模块

设立保护地是保护生物多样性的最有效举措。“半个地球”愿景提出将50%的面积纳入保护地,并有效保护85%的物种,是全球生态保护的目标。IUCN保护地分类系统是国际通用的标准,一系列优先保护模块研究则对保护地的识别进行着探索。本文旨在通过对这些模块的保护目标、识别标准等进行分析,为保护地科学识别提供合理参考。主要结论如下:（1）物种、栖息地与人类活动是各模块的主要考虑要素,识别标准包括物种丰富度、生境转变率、人类活动强度等;（2）各模块对生境转变率的考虑有“亡羊补牢”和“未雨绸缪”两种思路,对人类活动强度的考虑有直接和间接之分;（3）各模块分布面积占比在5.77%~25.32%之间,总范围占全球陆表的55.59%,超过了“半个地球”愿景的目标比例。     

MONTANA'S EXPERIENCE IN RESERVING YELLOWSTONE RIVER WATER FOR INSTREAM BENEFICIAL USES - THE RESERVATION DECISION1

ABSTRACT: The Yellowstone River in Montana produces an abundant supply of high quality water, but in the early 1970's, the specter of mushrooming energy development in the drainage with its attendant demands for large volumes of water prompted this state to initiate steps to protect existing users and to control future water uses. A Water Use Act was passed in 1973, and a moratorium was subsequently placed on the granting of new permits for major diversion. During this moratorium, various governmental entities were given the opportunity to request the reservation of water for future beneficial uses, including instream purposes. An earlier paper described the reservation applications that were received by the state, and it also summarized the legal framework of the reservation process in Montana. Since that time, the responsible state agency has had the opportunity to review the reservation requests, and its final decision in this regard was announced in December of 1978. This paper describes the details of this decision. Basically, an attempt was made to preserve the integrity of the stream while also strengthening its agricultural uses. In addition, a portion of the flow was not earmarked which will provide some flexibility in reacting to future demands.     

Biodiversity: gaps in knowledge

The Convention on Biological Diversity set conservation of biodiversity on the world agenda. Gaps in knowledge need to be addressed for actions to be effective and sustainable. Gaps include: species diversity, micro-organisms and their ecological roles, ecological and geographical status of species, human capacity to assess and forecast bio-ecological degradation. Requirements for global inventories call for worldwide collaboration. Criteria for setting priorities need to be formulated and agreed.Biodiversity in an eco-geographical region, the southern Mediterranean, is discussed as a case study. Outlines of national actions to contribute to world endeavor are outlined.
