Abstract/Summary: As a global community, we have a responsibility to ensure the long-term future of our natural heritage.  As part of this, it is incumbent upon us to do all that we can to reverse the current trend of biodiversity loss, using all available tools at our disposal. One effective mean is safeguarding of those sites that are highest global priority for the conservation of biodiversity, whether through formal protected areas, community managed reserves, multiple-use areas, or other means.  This special issue of the Journal of Threatened Taxa examines the application of the Key Biodiversity Area (KBA) approach to identifying such sites.  Given the global mandate expressed through policy instruments such as the Convention on Biological Diversity (CBD), the KBA approach can help countries meet obligations in an efficient and transparent manner. KBA methodology follows the well-established general principles of vulnerability and irreplaceability, and while it aims to be a globally standardized approach, it recognizes the fundamental need for the process to be led at local and national levels.  In this series of papers the application of the KBA approach is explored in seven countries or regions: the Caribbean, Indo-Burma, Japan, Macedonia, Mediterranean Algeria, the Philippines and the Upper Guinea region of West Africa. This introductory article synthesizes some of the common main findings and provides a comparison of key summary statistics.

 Introduction

 

Human beings today are confronted with a difficult dilemma regarding global biodiversity conservation.  We face a serious crisis as we continue to lose biodiversity at an alarming rate as well as to the environmental benefits it provides. At the same time, societies seem unwilling to make investments in conservation that are commensurate with the enormous scale of the problem.  For conservation professionals this means that there are insufficient resources for biodiversity conservation and the task of conserving our natural heritage appears increasingly daunting.  While the papers presented in this special issue of the Journal of Threatened Taxa do not pretend to have the solution for how to solve the biological crisis, or increase societal concern (as expressed by investment), they do provide examples of how sound, data-driven, transparent processes can be used to draw attention to those areas on ground (or water) that are most significant targets for safeguarding biodiversity. Several ways of identifying sites of biodiversity conservation importance have been developed and applied over the past few decades.  This special issue focuses on the overarching concept of areas of global biodiversity conservation significance or “Key Biodiversity Areas” (KBAs) and, in particular, on issues associated with the application of the criteria used to identify them in seven countries or regions around the world. Fundamental to the KBA process is the generation of maximum support for conserving the sites identified, and the use of the best possible information.  This is achieved by making the process of identifying KBAs as one that is led by local organizations, but which applies and maintains a globally standardized methodology.  The Key Biodiversity Area approach is an effective tool for identifying a priority set of globally significant sites for conservation. Once identified, there is often a need to prioritize where scarce resources should be first directed in order to target the most urgent conservation action.

While KBAs are identified based specifically on biodiversity values, it is recognized that this biodiversity does not exist in isolation and that people often can and should play an important role in the maintenance and management of these areas.  For this reason, the issue of manageability is brought directly into decisions regarding the delineation of KBAs.  Ultimately, it is hoped that KBAs have the potential to be managed for conservation as single coherent units (e.g. single local government, community group, basin catchment, landowner, etc.).  The process explicitly acknowledges that there are several ways in which a KBA can be conserved, either as a formal protected area (e.g. IUCN Class I-VI protected areas; Dudley(2008)) or through other effective means such as community-conserved area, community reserve, indigenous reserve, conservation easement, catchment management, etc. Additionally, it is important to note that while social and cultural aspects of the landscape do not play a role in the identification of KBAs (aside from aspects of boundary delineation), they are significant when planning conservation action.

The development of KBA methodology began with the identification of important sites for birds. This is attributable, at least in part, to the large amounts of data that are available for birds, as a result of their popularity for study by both experts and amateurs. For nearly three decades, the BirdLife International Partnership has been working to identify Important Bird Areas (IBAs) around the world (Fishpool et al. in prep.).  IBAs have been identified by local conservation organizations using the same global methodology in all countries, making the resulting priorities comparable. This concept of identifying important areas for a taxonomic group began to be used by other organizations for other groups, such as Important Plant Areas (led by Plantlife International; Anderson (2002), Plantlife (2004)), Important Freshwater Biodiversity Areas (led through the IUCN Freshwater Programme; Darwall & Vié (2005)) and Prime Butterfly Areas (as identified in Europe by Butterfly Conservation Europe; van Swaay & Warren (2003)).  In order to bring all of these processes and knowledge under a single umbrella methodology and process, an expert workshop was held in 2004 in Washington, DC, USA to develop draft cross-taxon criteria for identifying KBAs. These criteria were laid out in a paper by Eken et al. (2004) and expanded upon by Langhammer et al. (2007), and then were refined for the marine realm by Edgar et al. (2008) and for the freshwater biome by Holland et al. (2012).

 

 

Key Biodiversity Area criteria

 

The two core underlying principles for identification of Key Biodiversity Areas are vulnerability and irreplaceability, both of which are common elements in conservation planning (Margules & Pressey 2000).  While vulnerability is a measure of the scarcity of options in time for conserving biodiversity (often described in terms of the threat level of a given species or ecosystem), irreplaceability is a measure of the spatial options that exist for conserving biodiversity associated with a particular site (e.g. is it the only site where the species occurs, or is that species found at 20 other sites?).  The greatest significance for immediate conservation action are at those sites where both vulnerability and irreplaceability are high, and conversely, lower at sites which hold less threatened and more widely distributed species and ecosystems. Within the two higher-level criteria of vulnerability and irreplaceability, multiple sub-criteria have been developed (see Table 1).

While very similar, there are differences between the KBA criteria shown in Table 1 and those from which they were derived, for birds, through the Important Bird Area process, and for plants, by the Important Plant Area program—see Appendix 1.  A process is ongoing through an IUCN task force (the Species Survival Commission / World Commission on Protected Areas Joint Task Force on Biodiversity and Protected Areas) to explore the applicability of these criteria to other taxa and biomes, and, where appropriate, refine further and standardize these, and other, criteria for identifying sites of biodiversity conservation significance.

The IUCN Red List of Threatened Species serves as the primary basis for incorporating vulnerability into KBA assessments. Nearly 60,000 species have now been assessed by IUCN using standardized criteria, and the associated information is available at www.iucnredlist.org.  Sites that hold significant populations of one or more Critically Endangered, Endangered or Vulnerable species may be selected as KBAs.  For example, Hellshire Hills in Jamaica qualifies as a KBA because of the presence of three threatened species: one mammal and two birds (Anadón-Irizarry et al. 2012).

One of the irreplaceability sub-criteria concerns restricted-range species.  Here, a site may qualify if it holds ≥5% of the population of one or more species of restricted range, currently defined as 50,000km2, which has proved suitable for terrestrial vertebrates. For plants a restricted-range threshold of 5,000km2 is more appropriate (e.g Yahi et al. 2012). An example of such a site is Djurdjura in Mediterranean Algeria, which holds significant proportions of 27 such restricted-range plant species.  In cases where there are no detailed population data available for species, it is often possible to use surrogates, such as range size, especially when it is simply common sense that a site holds at least 5% of the population (e.g. when half of the entire range of a species is limited to a single site, or when a fish is known from only one lake).

The second irreplaceability sub-criterion deals with congregations of a species.  Here, a species may trigger the sub-criterion if it is known to congregate in numbers exceeding 1% of the global population at the site. Again, it is often necessary to use surrogates or estimates, given the general lack of detailed data on species populations.  Buguey Wetlands, in Luzon, Philippines, holds more than threshold numbers of five congregatory bird species and thus qualifies as a KBA (Ambal et al. 2012). While this criterion has so far been largely applied for birds, it will become more widely used as KBAs are identified for bat roost caves, spawning congregations of fish etc.

The third sub-criterion addresses bioregionally restricted assemblages.  To qualify as a KBA under this sub-criterion, a site must hold a significant component of the species restricted to a particular bioregion. The threshold for this criterion has still to be developed fully, but sites have been identified for birds, using the definition shown in Appendix 1, one specific Indo-Burman example is Tam Dao in Vietnam, which qualified based on the presence of 39 bird species restricted to the Sino-Himalayan Subtropical Forests Bioregion, and nine restricted to the Indochinese Tropical Moist Forest Bioregion (Tordoff 2002).

As mentioned previously, those sites that are extremely vulnerable and completely irreplaceable are potentially in most urgent need of conservation action.  The identification and conservation of this set of sites is the aim of the Alliance for Zero Extinction (www.zeroextinction.org).  These are KBAs that hold the last remaining population of one or more Critically Endangered or Endangered species and each is therefore both completely irreplaceable and extremely vulnerable - if we lose one of these sites, then we stand to lose at least one species to extinction.

 

 

Links to global policy instruments and other initiatives

 

The identification of sites of global biodiversity conservation significance has a long history of application to policy instruments.  The 1971 Ramsar Convention on Wetlands establishes nine standard criteria for the identification of “wetlands of international importance”, which have been applied in 160 countries to identify 1,960 sites in total till date (www.ramsar.org).  The 1972 World Heritage Convention similarly draws from ten standard criteria, of which four have so far been used to identify 211 natural and natural/cultural World Heritage Sites (whc.unesco.org).  All of these criteria can be broadly classified as being based on either irreplaceability or vulnerability.

The 1992 Convention on Biological Diversity (www.cbd.int) added great momentum to the documentation of sites of global biodiversity conservation significance following standard criteria.  Its Conference of the Parties Decision VI/9 established a Global Strategy for Plant Conservation, within which Target five requires “Protection of 50 percent of the most important areas for plant diversity assured”, with Decision X/17 increasing this to 75%.  Under the Thematic Programme on Marine and Coastal Biodiversity, Decision IX/20 established seven “scientific criteria for identifying ecologically or biologically significant marine areas in need of protection”; the Global Ocean Biodiversity Initiative (www.gobi.org) has been established to support such identification.  Meanwhile, the Thematic Programme on Mountain Biodiversity aims to “Establish effectively and appropriately managed protected areas in line with the program of work on protected areas to safeguard the highest priority Key Biodiversity Areas in mountain ecosystems” (Decision X/30).

Decision VII/28 of the CBD established the Programme of Work on Protected Areas, to “to support the establishment and maintenance, by 2010 for terrestrial and by 2012 for marine areas, of comprehensive, effectively managed, and ecologically representative national and regional systems of protected areas”.  In 2010, further guidance was provided in Decision X/31 to “Consider standard criteria for the identification of sites of global biodiversity conservation significance, when developing protected area systems drawing on the IUCN Red List of Threatened Species, established criteria in other relevant processes including those of the UNESCO Man and Biosphere Programme, the World Heritage Convention, the Ramsar Convention on Wetlands, threatened ecosystem assessments, gap analysis, Key Biodiversity Areas and Important Bird Areas”.

Most important of all, the 2010–2020 Strategic Plan for the Convention on Biological Diversity establishes a shared vision, mission, strategic goals and 20 Aichi Targets (http://www.cbd.int/sp/targets/), of which the eleventh requires the establishment of protected areas covering “by 2020, at least 17 percent of terrestrial and inland water areas, and 10 percent of coastal and marine areas, especially areas of particular importance for biodiversity”.  Decision X/20 also calls for the scientific bodies and the Liaison Group of the Biodiversity-related Conventions to enhance cooperation regarding “scientific criteria for the identification of ecologically or biologically significant areas in need of protection”.

Numerous other sub-global policy instruments draw on standard criteria for identification of sites of biodiversity conservation significance.  For example, the European Union’s 1979 Birds Directive and 1992 Habitats Directive require, respectively, the designation of Special Protection Areas and Special Areas of Conservation, which together comprise the Natura 2000 network (www.natura.org).  Many national governments draw upon such criteria in undertaking gap analysis and protected-area system planning, towards meeting their commitments to Ramsar, World Heritage, the Convention on Biological Diversity, and other instruments.

Of course, the identification of Key Biodiversity Areas as sites of global biodiversity conservation significance has great importance for many other sectors of society, in addition to its policy applications. In the private sector, the International Finance Corporation’s Performance Standard six draws for its safeguard policies on the fact that “Critical habitats are areas with high biodiversity value, including (i) habitat of significant importance to Critically Endangered and/or Endangered species; (ii) habitat of significant importance to endemic and/or restricted-range species; (iii) habitat supporting globally significant concentrations of migratory species and/or congregatory species; (iv) highly threatened and/or unique ecosystems; and/or (v) areas associated with key evolutionary processes” (IFC 2012).  Similar safeguard policies are in place in other international financial institutions, while the High Conservation Value Resource Network (www.hcvnetwork.org) similarly uses six criteria as safeguards within the certification of high conservation forests and other habitats and ecosystems.

The identification of Key Biodiversity Areas has enormous significance to local and indigenous communities. While difficult to document comprehensively, cases abound whereby local “site support groups” have emerged to implement conservation subsequent to global recognition of such significance.  These harness such recognition to generate conservation-related employment and income, stabilization of land tenure, maintenance of ecosystem services, resilience and ecosystem-based adaptation to climate change, educational opportunities, and community pride in local nature.  Ultimately, the long-term persistence of the biodiversity for which Key Biodiversity Areas are important will depend as a first line of defense on the people living in and around such sites.

 

 

Progress in identification of Key Biodiversity Areas

 

Important Bird Areas (IBAs), as the avian subset of KBAs, have been identified in nearly all countries, with only a few remaining where inventories have yet to be completed.  While the IBA program has been underway for nearly thirty years, the identification of sites of significance for other taxonomic groups is also advancing rapidly.  Important Plant Areas (IPAs) inventories have been completed for 36 countries and are partially complete or in progress in further 30.  Much of the focus of the IPA program till date has been in Europe, the Mediterranean parts of North Africa and the Middle East and parts of Asia.  The expansion of KBA processes around the world will undoubtedly result in the identification of KBAs triggered by plants, and the network of IPAs will likewise expand.  Similarly, the identification of globally important freshwater sites is in progress in more than 90 countries, including continental Africa (Darwall et al. 2011), continental Europe and the Indo-Burma Biodiversity Hotspot. Eighty countries have KBAs identified for multiple taxonomic groups with another 73 partially complete or in progress (see Image 1).  Additionally, marine KBA identification is complete or in progress in several marine regions including: Philippines (Ambal et al. 2012), Melanesia, Polynesia-Micronesia, and the Eastern Tropical Pacific.

This special issue examines in detail the results of seven Key Biodiversity Area analyses in the following regions/countries: the Upper Guinea (Kouame et al. 2012) region of West Africa (Côte d’Ivoire, Ghana, Guinea, Liberia, Sierra Leone), the Philippines, the Caribbean Islands, Macedonia (FYR) (Melovski et al. 2012), Algeria (Mediterranean portion), Indo-Burma (Tordoff et al. 2012) and Japan (Natori et al. 2012) (Image 2).

 

 

Key Findings - Methodological Issues

 

By gathering together the experiences of Key Biodiversity Area identification in seven regions, we can present a picture of the range of challenges faced when applying the criteria.  These methodological challenges can be divided into four broad topics:

1. Challenges in using the IUCN Red List as the basis for the vulnerability criterion

2. Discrepancies in application of the criteria in identifying important sites for different taxonomic groups and in different region

3. Application of provisional thresholds for restricted range, and lack of related data for some groups

4. Delineation challenges

 

On the first of these, a consistent challenge is that while more than 60,000 species around the world have now been assessed on the IUCN Red List, there remain significant gaps in coverage among taxonomic groups and regions, and some assessments are out-of-date.  While all regions mentioned the importance of increasing the taxonomic coverage of the IUCN Red List, the taxonomic group felt to be most in need of such effort differed somewhat between regions.  For example, while almost all papers suggested there is insufficient assessment of plants, this was not the case for the Caribbean Islands.  Also, while recognizing that the IUCN Global Freshwater Species Assessment work is continuing, there currently remains inadequate coverage of such species outside of their recent publication for Africa (Darwall et al. 2011) and what is available on the IUCN website (http://www.iucnredlist.org/initiatives/freshwater).

To compensate, authors often applied other means to capture some of the species that would otherwise have been missed had they relied solely on species on the IUCN Red List.  Thus, in Japan, for species other than mammals, birds and amphibians, national endemics that appear on the national red list were used to trigger KBA identification; for these, which have been identified using the IUCN criteria applied at the national scale, the national threat status should prove equivalent to the global Red List status.  In the Philippines, the authors ensured that taxonomic groups not well represented under the vulnerability criterion were included through the application of the irreplaceability criteria (specifically, the restricted-range sub-criterion).  Table 2 summarizes the criteria used and taxa covered for each of the countries/regions.

With regard to discrepancies in criteria application in site identification for different taxonomic groups and regions, two issues were exposed by the Macedonia (FYR) analysis, which combined existing IBA and IPA datasets.  Due to small but significant differences between the KBA criteria (Table 1) and the global IBA criteria (Appendix 1), nine Macedonian IBAs did not qualify as KBAs.  Thus, for example, species classified as Near Threatened on the IUCN Red List may be used as IBAs triggers but not for KBAs under the vulnerability criterion. However, in four cases the territory of excluded IBAs was retained within the KBA network because it overlapped with a qualifying IPA (e.g. KBA Jakupica).  On the other hand, KBA criteria currently incorporate biodiversity data above the species level differently between plants (for which IPAs consider threatened habitats and contextual species richness) and birds (for which IBAs consider biome-restricted assemblages). Thus, five Macedonian IPAs selected using threatened habitat and species richness data are not directly comparable with the Macedonian IBAs, and do not qualify as KBAs in this analysis, although the territory of one of these IPAs does also qualify as an IBA in its own right.

The thresholds for defining restricted-range species was also seen as problematic in several instances.  The authors of both the Macedonia (FYR) and Algeria papers used a threshold of 5,000km2 to define restricted range for plant species, since using the proposed 50,000km2threshold would have resulted in far too many species qualifying as potential KBA triggers (even so, over 150 plant species in Mediterranean Algeria qualify under the revised threshold).  In the Caribbean and Indo-Burma, the KBA processes limited the application of the restricted range sub-criterion to birds, given the paucity of population data for other species.

As for delineation, the biggest concern seems to have been the incorporation of political or management units in demarcation decisions.  In Indo-Burma and Macedonia, the authors leaned more toward delineation based on habitat patches and the biological needs of the trigger species, while others, such as Japan, incorporated management layers, such as municipal boundaries, into delineation of KBAs.  In several regions, including the Philippines, consultation workshops were viewed as a critical step in achieving the best possible delineation to build consensus around the final set of KBAs.  When existing datasets from established analyses are combined, the issue of overlapping sites needs to be addressed.  In Macedonia the KBAs that resulted from overlapping IPAs and IBAs were delineated on the basis of the union of their surfaces and, in more complex cases (when two or three KBAs had to be delineated from several overlapping IPAs and/or IBAs), the boundaries of either IPAs or IBAs were used to delineate KBAs.

A summary of some of the issues encountered in the various regions is given in Table 3.

 

 

Key Findings - comparison of results

 

This synthesis of seven papers which have applied an essentially uniform methodology for identifying sites of global biodiversity conservation significance gives us a unique opportunity to review and compare the results between countries and regions.  Given the different circumstances, including in size of the region or country, species endemism and richness, threats to natural habitats, intactness of these habitats, relative levels of development etc., it is not surprising there is a considerable range in the number of KBAs identified and in their relative sizes.

Thus, the average size of KBAs ranges from less than 200km2 (that is, equivalent to squares 14km on the side) in the Caribbean to over 800km2(equivalent to squares 28km on the side) in Upper Guinea (see Table 4).  While the small average size of KBAs in the Caribbean is doubtless attributable, in part, to the geography presented by these island systems, there is also considerable fragmentation of natural habitat within the islands, whereas the larger average size in Upper Guinea is surely due in part to the relative intactness of the habitat (especially in the west of the region).  There also appears to be a gradient from smaller sizes in more developed countries, such as Japan and Macedonia, to larger sizes in less developed ones, which could be due to both greater habitat fragmentation and a finer grain of biodiversity knowledge in developed countries.

As expected, the number and combined area of KBAs in each country/region increases with - and is presumably largely driven by - the number of threatened species in the country/region.  However, the size of the country or region itself, the percentage of its territory covered by KBAs, and the average size of KBAs appear to be largely independent of the number of threatened species.  Thus, as additional taxonomic groups are assessed by the IUCN Red List, the tallies of threatened species occurring in most countries and regions are likely to increase, and we can anticipate that additional KBAs will need to be identified, yielding a larger combined total area of KBAs but not necessarily larger individual KBAs.

 

 

Call to Action

 

There is hope in the fight to stop the current global losses of biodiversity.  Worldwide, 187 countries are signatures to the Convention on Biological Diversity and as mentioned previously, the new Strategic Plan for Biodiversity gives these countries a shared vision, mission, strategic goals, and 20 ambitious yet achievable targets to halt the loss of biodiversity.  The fact that the global community is giving biodiversity prominence through a uniform approach is encouraging news.

The conservation community must work with the community of nations to conserve the fellow inhabitants of this planet from the excesses of humanity.  We need to bring the science, the politics and policy together for urgent action to ensure that biodiversity data, such as KBAs, are incorporated in local, national and regional planning and management.  Specifically, we recognize four key recommendations emerging from the KBA process so far, as reflected in the seven contributions to this special issue:

 

1.  Conserve already-recognized sites

Sites of global biodiversity conservation significance have already been identified in every country in the world, whether as IBAs, IPAs, AZE sites, or other KBAs. The single greatest contribution which the world’s nations can make towards their commitment to Aichi Target 11 is to ensure that:

a) Those sites that are already being conserved by protected areas or other effective mechanisms continue to be effectively managed in ways consistent with the maintenance of the biodiversity for which they are important; and,

b) Those sites not yet being conserved are urgent targets to safeguard through the establishment of new protected areas or other effective mechanisms;

 

2. Fully utilize the IUCN Red List in site identification

The last decade has seen enormous advances in the taxonomic coverage of the IUCN Red List (Rodrigues et al. 2006), making available large quantities of data on the distribution and extinction risk of, for example, amphibians, fishes, odonates, and plants. Where these data have not yet been incorporated into national processes for identifying sites of global biodiversity conservation significance, doing so is an urgent priority.

 

3. Continue to expand the taxonomic coverage of the Red List, to increase the quality and quantity of up-to-date data, as well as their availability, on species, taxonomy and habitats

Despite recent advances in coverage, substantial biases remain. IUCN has mobilized a “Barometer of Life” campaign, targeting more comprehensive Red Listing of plants, fungi, reptiles, and freshwater and marine taxa.

 

4. Strengthen the application of global standards in national site identification

The increasing globalization of our world places increasing demands for standardization of the processes for identifying significant sites, to fulfill the needs of international conventions, the international financial institutions and development banks, and the private sector. As the work of the IUCN WCPA/SSC Joint Task Force delivers more uniform standards for the identification of important sites, we anticipate that national application of these standards will provide ever greater conservation benefit.

Finally, KBAs’ identification is an iterative process and we can only encourage people to continue identifying sites of global biodiversity conservation significance in countries, biomes or taxonomic groups that have still not been taken into consideration.
