Leveraging the Red List of Ecosystems for action on coral reefs through the Kunming‐Montreal Global Biodiversity Framework

AbstractCountries have committed to conserving and restoring ecosystems after signing the Kunming‐Montreal Global Biodiversity Framework (GBF). The IUCN Red List of Ecosystems (RLE) will serve as a headline indicator to track countries' progress toward achieving this goal. Using Kenyan coral reefs, we demonstrate how nations implementing the GBF can use standardized estimates of ecosystem degradation from RLE assessments to support site‐specific management decisions. We undertook a reef‐by‐reef analysis to evaluate the relative decline of four key ecosystem components over the past 50 years: hard corals, macroalgae, parrotfish, and groupers. Using the two benthic indicators, we also calculated standardized estimates of state to identify reef sites which maintain a better condition through time relative to adjacent sites. Kenya's coral reefs have degraded across all four ecosystem components. At more than half the monitored sites parrotfish and grouper abundance declined by more than 50%, while coral cover and macroalgae‐coral ratio declined by at least 30%. This resulted in an Endangered threat status for coral reefs in Kenya (under criterion D of the RLE). The results can guide management actions related to 9 of the 23 GBF targets. For example, we identified several sites with relatively healthy benthic and fish communities as candidate areas for protection measures under Target 3. The RLE has a key role to play in monitoring and meeting the goals and targets of the GBF, and our work demonstrates how using the wealth of data within these assessments can inform local‐scale ecosystem management and amplify the GBF's impact.

The Kunming-Montreal Global Biodiversity Framework needs headline indicators that can actually monitor forest integrity

Abstract Intact native forests under negligible large-scale human pressures (i.e. high-integrity forests) are critical for biodiversity conservation. However, high-integrity forests are declining worldwide due to deforestation and forest degradation. Recognizing the importance of high-integrity ecosystems (including forests), the Kunming-Montreal Global Biodiversity Framework (GBF) has directly included the maintenance and restoration of ecosystem integrity, in addition to ecosystem extent, in its goals and targets. Yet, the headline indicators identified to help nations monitor forest ecosystems and their integrity can currently track changes only in (1) forest cover or extent, and (2) the risk of ecosystem collapse using the IUCN Red List of Ecosystems (RLE). These headline indicators are unlikely to facilitate the monitoring of forest integrity for two reasons. First, focusing on forest cover not only misses the impacts of anthropogenic degradation on forests but can also fail to detect the effect of positive management actions in enhancing forest integrity. Second, the risk of ecosystem collapse as measured by the ordinal RLE index (from Least Concern to Critically Endangered) makes it unlikely that changes to the continuum of forest integrity over space and time would be reported by nations. Importantly, forest ecosystems in many biodiverse African and Asian nations remain unassessed with the RLE. As such, many nations will likely resort to monitoring forest cover alone and therefore inadequately report progress against forest integrity goals and targets. We concur that monitoring changes in forest cover and the risk of ecosystem collapse are indeed vital aspects of conservation monitoring. Yet, they are insufficient for the specific purpose of tracking progress against crucial ecosystem integrity components of the GBF’s goals. We discuss the pitfalls of merely monitoring forest cover, a likely outcome with the current headline indicators. Augmenting forest cover monitoring with indicators that capture change in absolute area along the continuum of forest integrity would help monitor progress toward achieving area-based targets related to both integrity and extent of global forests.

Synergies and complementarities between ecosystem accounting and the Red List of Ecosystems.

Safeguarding biodiversity and human well-being depends on sustaining ecosystems. Two global standards for quantifying ecosystem change, the International Union for Conservation of Nature Red List of Ecosystems (RLE) and the United Nations System of Environmental-Economic Accounting Ecosystem Accounting (EA), underpin headline indicators for the Kunming-Montreal Global Biodiversity Framework. We analyse similarities and differences between the standards to understand their complementary roles in environmental policy and decision-making. The standards share key concepts, definitions of ecosystems and spatial data needs, meaning that similar data can be used in both. Their complementarities stem from their differing purposes and thus how data are analysed and interpreted. Although both record changes in ecosystem extent and condition, the RLE analyses the magnitude of change in terms of risk of ecosystem collapse and biodiversity loss, whereas EA links ecosystem change with the ecosystem's contributions to people and the economy. We recommend that the RLE and EA should not be treated as unrelated nor undertaken in isolation. Developing them in concert can exploit their complementarities while ensuring consistency in foundational data, in particular ecosystem classifications, maps and condition variables. Finding pathways for co-investment in foundational data, and for knowledge-sharing between people and organizations who undertake RLE assessments and accounting, will improve both processes and outcomes for biodiversity, ecosystems and people.

Using the RedList of Ecosystems andthe Nature-based Solutions Global Standard as an integrated process for climate change adaptation inthe Andean high mountains.

Under anthropogenic pressures and climate change, most ecosystems are showing signs of reduced resilience. Unfortunately, some are more at risk of collapse and, without interventions, they may lose biodiversity, ecological integrity and ecosystem services. Here, we describe two tools that were developed under the auspices of the International Union for Conservation of Nature,the RedList of Ecosystems and the Nature-based Solutions Global Standard, and their capacity to first identify the ecosystems at risk of collapse in a nation and then develop solutions based on nature to improve their resilience. Nature-based solutions include, for example ecosystem-based adaptation, where solutions are developed to meet the needs of the local people while protecting nature to ensure greater resilience of the social-ecological system, not only the natural ecosystem. We discuss through a case study in the Andean high mountains and páramo social-ecological system how these approaches have been used in Colombia. We then discuss lessons learned and challenges that may reduce the capacity of a community to initiate such interventions, such as national policies and funding restrictions. We also discuss through another early case in Ecuador the importance to adapt these types of interventions to the geographical and cultural context of the social-ecological systems. This article is part of the theme issue 'Bringing nature into decision-making'.

Perspectives on the timing of ecosystem collapse in a changing climate.

Climate change is one of the most important drivers of ecosystem change, the global-scale impacts of which will intensify over the next 2 decades. Estimating the timing of unprecedented changes is not only challenging but is of great importance for the development of ecosystem conservation guidelines. Time of emergence (ToE) (point at which climate change can be differentiated from a previous climate), a widely applied concept in climatology studies, provides a robust but unexplored approach for assessing the risk of ecosystem collapse, as described by the C criterion of the International Union for Conservation of Nature's Red List of Ecosystems (RLE). We identified 3 main theoretical considerations of ToE for RLE assessment (degree of stability, multifactorial instead of one-dimensional analyses, and hallmarks of ecosystem collapse) and 4 sources of uncertainty when applying ToE methodology (intermodel spread, historical reference period, consensus among variables, and consideration of different scenarios), which aims to avoid misuse and errors while promoting a proper application of the framework by scientists and practitioners. The incorporation of ToE for the RLE assessments adds important information for conservation priority setting that allows prediction of changes within and beyond the time frames proposed by the RLE.

Assessing the conservation status of mangroves in Rakhine, Myanmar

Abstract Ecosystem degradation is a key challenge that human society faces, as ecosystems provide services that are tied to human well‐being. Particularly, mangrove ecosystems provide important services to communities but are suffering heavy degradation, loss and potential collapse due to anthropogenic activities. The IUCN Red List of Ecosystems is a transparent and consistent framework for assessing ecosystems' risk of collapse and is increasingly used to inform legislation and ecosystem management globally. Satellite data have become increasingly common in environmental monitoring due to their extensive spatial and temporal coverage. Here, recent advances in analyses using satellite‐derived data were implemented to reassess the conservation status of the ‘Rakhine mangrove forest on mud’, an important intertidal ecosystem in Myanmar, extending a previous national Red List assessment that assessed the ecosystem as Critically Endangered. By incorporating additional data sources and analyses, the extended assessment produced more robust results and reduced the uncertainty in the previous assessment. Overall, the ecosystem was assessed as Critically Endangered (range: Vulnerable to Critically Endangered) as a result of historical mangrove extent loss. Recent losses and biotic disruptions were also observed, which would have led to the ecosystem being assessed as Vulnerable. While the final outcome of the Red List assessment remained at Critically Endangered due to the historical state of the mangroves pre‐dating the temporal coverage from satellite data, the uncertainty of the ecosystem's status was reduced, and the reassessment highlighted the recent areal changes and mangrove degradation that has occurred. The importance of conducting reassessments when new data become available is discussed, and a template for future mangrove Red List assessments that use satellite data as their primary source of information to improve the robustness of their results is presented.

Assessment of Wetland Ecosystem’s Health Using Remote Sensing – Case Study: Burullus Wetland – Ramsar Site

Complex ecosystems as wetlands are very sensitive to changes and disturbances. Human activities causing habitat fragmentation that alter landscapes affect the wetland ecosystems and negatively influence biodiversity. The health of the ecosystem is measured as a homeostasis between the system components and stability or resilience of the system against disturbance; therefore, any anthropogenic disturbances can cause dramatic changes in the balance of wetland ecosystem. Burullus, the second largest of the Egyptian northern coastal wetlands along the Mediterranean coast, has been recognized recently as critically endangered ecosystem according to an assessment using IUCN Red List of ecosystems. The study sought to assess Burullus wetland’s health based on multispectral indicators related to the structure, function, and resilience of the ecosystem. Three indices were calculated to quantify the health of the wetland: the structure index, vigor index, and resilience index. The overall status of the wetland indicates a dynamic state and rapid transformation, which occurred over the study period. The outcomes indicated that Burullus’s health has progressively deteriorated in the recent investigated years of 2016 and 2019 compared to the reference years of 1984 and 1986. The assessed indicators revealed a trend towards more deterioration of its ecological system due to the LULC transformations, anthropogenic interventions, and overexploitation of its natural resources. In addition, the growth in the impervious surfaces by 9% in the recent years due to expansion in urbanization was detected. All of these factors may affect the ecological balance and the health of the wetland to some extent. The fragility of this wetland and the continuous fragmentation of it occurs due to human activities that threaten its important and unique habitats. The integrated framework for the assessment of Burullus wetland’s health based on remotely sensed data and using geospatial techniques can be utilized for the assessment of other similar coastal wetlands at national and regional scales.

Undergraduate Internship on Yamuna River Exploration: Raising Awareness about SDG6

A semester-long internship was designed for undergraduate students at the University of Delhi, India. Teams comprising 30 students from all over the University were trained to carry out field exploration activities on the Yamuna River flowing in Delhi. The students were provided with portable kits to measure the physicochemical parameters at a selected bank of the Yamuna River. Students documented the invertebrate fauna in the riparian zone of the banks. At the same time, they noted the anthropogenic polluting activities on the bank of the Yamuna River. This internship educated students about the UN’s Sustainable Development Goals (SDGs). They all studied Ecology and Environmental Science in their undergraduate curriculum, but they all confessed that they were unaware of the 17 SDGs and the deteriorating health of the Yamuna River in the city. We educated students about the freshwater emergency recovery plan and the International Union for Conservation of Nature (IUCN) red list of ecosystems. This internship is a great example of an undergraduate-directed study or research experience that supported student constructivism and inquiry-based learning, and this research article elaborates on student reports and situational interest in freshwater biology to achieve SDG6.

The role of the Red Lists of Ecosystems in leveraging sustainability changes in Finland – perceptions of the assessors

ABSTRACT The human impact on nature has now reached a level at which the well-being of future human society is at risk. Therefore, transformative change in society is needed. Environmental assessments contribute to shaping environmental policy, potentially leveraging transformative change. Red Lists are a key information source on the state of biodiversity. Our aim was to study the Red List authors’ perceptions of how Red Lists contribute to leveraging sustainability changes. We interviewed 15 of the authors of the forest and peatland sections of the Finnish Red List of Ecosystems 2018. We used the framework of sustainability leverage points to locate sustainability changes that Red Lists have leveraged in the social part of the Finnish social-ecological system. Our results show how the assessors perceived the influence of the Red Lists at most of the leverage points, including the deepest ones, and how these influences simultaneously co-exist in several leverage points. The most prominent sustainability changes were linked with legislation and information flows, whereas current paradigms, system goals and legislation appeared to prevent Red Lists from leveraging sustainability changes in Finland. We conclude that the production and dissemination processes of Red List knowledge can make an important contribution to sustainability changes.

A comprehensive threat analysis to support the red list of marine and coastal ecosystems of Colombia

IntroductionHuman activities represent a growing threat to biodiversity, increasing species extinction and leading ecosystems to collapse. The knowledge of the spatial distribution of threats to ecosystems is fundamental to understanding their risk of collapse as defined by the Red List of Ecosystems, an International Union for Conservation of Nature (IUCN) global standard to guide conservation and management actions. Colombia is a megadiverse country; almost half of its territory is marine, and its ecosystems are subject to anthropogenic and climatic threats.MethodologyThis study provides a quantitative map assessment for a set of relevant anthropic and climatic threats and impacts on the marine and coastal areas of Colombia, intending to perform the threat description component of the Red List assessment protocol. A cumulative impact assessment was applied to analyze the threat levels (TLs) and impact levels of 12 anthropogenic and climatic pressures.ResultsThe observed TL patterns meet spatial expectations, revealing that the assessment units in the Caribbean Sea are more threatened than those in the Pacific Ocean, and continental areas are more threatened than the oceanic ones. Habitat transformation and sea warming were the threats with the most impact on coastal and marine ecosystems, respectively. Climatic threats were widely extended throughout the study area, occurring even in the most pristine zones (e.g., Malpelo Island).DiscussionClimate threats are challenging to national conservation strategies since these pressures are not completely manageable at local scales as they depend mainly on global efforts. Recommendations drawn from this work can guide actions for the conservation of the ecosystems of Colombia.

Addressing the Biodiversity Paradox: Mismatch between the Co-Occurrence of Biological Diversity and the Human, Financial and Institutional Resources to Address Its Decline

Pressures are mounting for the adoption of a Global Biodiversity Framework that transforms conservation and sustainable use efforts worldwide. Underlying this challenge is the biodiversity paradox: biological diversity predominantly concentrates in the tropics, while human, institutional, and financial resources are primarily located at higher latitudes both north and south. Addressing the biodiversity paradox requires the expansion and mobilization of human, institutional and financial resources around the world. We outline a model championed by the IUCN Species Survival Commission (SSC) that builds on the Species Conservation Cycle (Assess-Plan-Act-Network-Communicate) and recognizes that most conservation action occurs at the national or local level. Various strategies are applied to this end by the partners of Reverse the Red, a global movement that ignites strategic cooperation and science-based action to ensure the survival of wild species and ecosystems. The SSC contributes to Reverse the Red through two primary strategies: National Species Specialist Groups and Centers for Species Survival. By building on existing expert networks and catalyzing efforts with established local institutions, we aim to significantly expand capacity to implement conservation action at the national level and reverse the negative trends indicated by the IUCN Red List of Threatened Species and the Red List of Ecosystems.

Addressing Climate Change Vulnerability in the IUCN Red List of Ecosystems—Results Demonstrated for a Cross-Section of Major Vegetation-Based Ecosystem Types in the United States

The IUCN Red List of Ecosystems (RLE) is a global standard for ecosystem risk assessment that integrates data and knowledge to document the relative risk status of ecosystem types as critically endangered (CR), endangered (EN), and vulnerable (VU). A series of indicators for each type gauge the probability of range wide “collapse”. Climate change vulnerability can factor into RLE assessments, especially as indicators of climate change severity under the criteria for environmental degradation over the recent and upcoming 50 years. We applied a new framework to assess climate change vulnerability—and thus, severity of climate change degradation—to a cross-section of 33 upland ecosystem types in the United States to demonstrate this input to the RLE. The framework addressed climate exposure and ecosystem resilience. Measures of climate change exposure used climate projections for the mid-21st century compared against a 20th century baseline. Augmenting measures in use for RLE assessment, measures of resilience included several for adaptive capacity, including topoclimate variability, diversity with functional species groups, and vulnerability of any keystone species. All 33 types were listed as VU (n = 22), EN (n = 9), or CR (n = 2) and 51% scored at least one step higher (e.g., LC up to VU) from climate change severity.

Documenting at‐risk status of terrestrial ecosystems in temperate and tropical North America

AbstractThe International Union for Conservation of Nature (IUCN) Red List of Ecosystems (RLE) is an emerging global standard for ecosystem risk assessment that integrates data and knowledge to document the relative risk status of ecosystem types. Here, we summarize initial findings from applying four IUCN RLE criteria to 655 terrestrial ecosystems in temperate and tropical North America, or 8.5% of the global land surface. A series of indicators are measured for each criterion to address trends in ecosystem extent (A), the relative restricted nature of its distribution (B), and the extent and relative severity of environmental degradation (C), and the extent and relative severity of disruption of biotic processes (D); all to gauge the probability of range wide “collapse.” Ecosystems are listed as collapsed, critically endangered, endangered, vulnerable, near threatened, least concern, data deficient, or not evaluated. Taking uncertainty into account, 219 (33%) of terrestrial ecosystem types were listed as threatened (i.e., either critically endangered, [7%], endangered [14%], or vulnerable [13%]). Examples include tallgrass prairies, oak savannas, longleaf pine woodlands, floodplain forests, mesic hardwood forests, and dry tropical forests. Historically, these threatened ecosystems occurred across about 45% of the continental study area, and today account for about 30%. The RLE provides one important focus for prioritizing conservation effort.

Vulnerability to collapse of coral reef ecosystems in the Western Indian Ocean

Ecosystems worldwide are under increasing threat. We applied a standardized method for assessing the risk of ecosystem collapse, the International Union for Conservation of Nature (IUCN) Red List of Ecosystems, to coral reefs in the Western Indian Ocean (WIO), covering 11,919 km2 of reef (~5% of the global total). Our approach combined indicators of change in historic ecosystem extent, ecosystem functioning (hard corals, fleshy algae, herbivores and piscivores) and projected sea temperature warming. We show that WIO coral reefs are vulnerable to collapse at the regional level, while in 11 nested ecoregions they range from critically endangered (islands, driven by future warming) to vulnerable (continental coast and northern Seychelles, driven principally by fishing pressure). Responses to avoid coral reef collapse must include ecosystem-based management of reefs and adjacent systems combined with mitigating and adapting to climate change. Our approach can be replicated across coral reefs globally to help countries and other actors meet conservation and sustainability targets set under multiple global conventions—including the Convention on Biological Diversity’s post-2020 global biodiversity framework and the United Nations’ Sustainable Development Goals.

Stakeholders from diverse backgrounds make similar judgments about ecological condition and collapse in Mongolian rangelands

AbstractComplex socio‐ecological problems typically involve a variety of stakeholders, with viewpoints that may range between consensus and deep disagreement over values and judgments. Understanding this distribution of opinion is key to finding conservation solutions. We examine how stakeholders with widely different backgrounds vary in their judgments of rangeland degradation in Mongolia's Gobi Desert, where grazing intensity is a contested issue. We gathered the judgments of 92 stakeholders from a highly diverse group including: (i) nomadic pastoralists (herders), (ii) experts in botany, (iii) experts in wildlife ecology, and (iv) conservation policy practitioners. These stakeholders considered degradation in five ecosystems including Desert shrublands, Steppe, and Siberian Elm riparian woodlands, using written site descriptions in a workshop context. Each stakeholder considered degradation using two conceptual frameworks: the notion of “ecosystem collapse” described by the IUCN Red List of Ecosystems and the concept of ecological condition. We used generalized additive models (GAMs) to examine the relationship between vegetation attributes and stakeholder judgments of condition. Although individual stakeholder varied in their judgments, we found only relatively small systematic variations between different types of stakeholders. Similarly, we found the degree of specialization of experts had little effect on the condition score. We also used GAMs to examine the relationship between vegetation attributes and stakeholder judgments of collapse, finding little variation between groups. We also explored the threshold of overall vegetation cover where stakeholders are likely to shift their judgment from collapsed to not collapsed, and while differences between ecosystems were observed, we found consensus between the different stakeholder groups within each ecosystem. Our results suggest that, at least in the context of the Southern Mongolia, diverse stakeholder groups have convergent views in respect to ecological degradation.

Strengthening the Scientific Basis of Ecosystem Collapse Risk Assessments

Progress is being made in assessing the conservation status of ecosystems, notably through initiatives such as the IUCN Red List of Ecosystems (RLE) and the NatureServe Conservation Status Assessment (NCS). Both of these approaches consider conservation status in terms of the risk of ecosystem collapse. However, the scientific understanding of ecosystem collapse is still at a relatively early stage. Consequently, concerns have been raised regarding the scientific basis of ecosystem conservation assessments focusing on collapse risk. Here I explore how these concerns might potentially be addressed by considering how the concept is defined, and by briefly reviewing the theoretical basis of ecosystem collapse. I then examine the implications of recent research results for the design of ecosystem collapse risk assessments, and the challenges identified in those assessments conducted to date. Recommendations are made regarding how collapse risk assessments might be strengthened based on current scientific understanding, and how this understanding could be improved by further research. In addition, I examine the potential implications for conservation policy and practice if the scientific basis of collapse risk assessments is not strengthened in this way.

South Africa’s Red List of Terrestrial Ecosystems (RLEs)

Ecosystem level indicators are emerging as important pillars of the post-2020 global biodiversity framework of the Convention on Biological Diversity; at the same time, the IUCN Red List of Ecosystems (RLEs) is experiencing rapid global uptake. We applied a systematic RLE assessment to 456 terrestrial ecosystems in South Africa between 2017 and 2021. What sets South Africa apart in this endeavour is that an independently formulated ecosystem threat status indicator was developed between 2004 and 2008 and the list of threatened ecosystems (effectively a proto RLE) was integrated into the national environmental regulatory framework in 2011. Through this, Critically Endangered and Endangered types were afforded a form of statutory protection through increased regulation of land-use change activities. We describe the transition to the IUCN RLE framework and focus on both the technical steps of incorporating the best available data into a credible assessment, and the unique social and legal processes to ensure that the biodiversity conservation sector in South Africa understood and supported the proposed replacement of the existing list of threatened ecosystems (2011) with the RLE (2021). We discuss the policy development steps required in South Africa, and the pros and cons of maintaining a legislative link for RLE implementation.

Application of IUCN Red List of Ecosystems to assess the ecological status of marine bar ecosystems of Burullus wetland: A Ramsar site

The IUCN Red List of Ecosystems has been employed to assess the status of ecosystems and evaluate the risk of their collapse. The RLE assessment was conducted on the main ecosystems of the marine bar of Burullus wetland; sand plain and salt marshes ecosystems of the marine bar which separates the lake from the Mediterranean Sea. Four criteria were used for conducting the assessment; (A) reduction in distribution, (B) constricted distribution, (C) abiotic components degradation, and (D) disruption of biotic processes and interactions. The integration of remotely-sensed data allowed the application of RLE to study the changes in ecosystems distribution for Criteria A and B. Criterion A showed the same result for sand plain and salt marshes as Critically Endangered (CR). This indicates the distribution of the marine bar is extremely affected by the urban and human activities in the region. It is also expected to be affected by any slight changes in the sea-level and costal erosions in the future in terms of disruption in biotic processes and interactions. Criteria D was applied using floristic quality assessment for current floristic composition and the available historic data. The results show that sand plain and salt marshes are Near Threatened (NT). However, the application of Criteria C was Data Deficient DD due to lack of long term data about the abiotic variables responsible for environmental degradation. The identical results of RLE assessment of sand plain and salt marshes reflect that both ecosystems are equally affected by the ongoing activities in the region, particularly over the last few years. The results indicate that the marine bar ecosystems were disturbed by anthropogenic events such as urban development, grazing and farming. Also natural events such as climate change and its consequences are expected to have severe impacts on the marine bar in the future. Therefore, further studies should focus on the study of the main interactions and processes in the marine bar ecosystems.

Assessing the threat of landscape transformation and habitat fragmentation in a global biodiversity hotspot

AbstractHabitat loss and habitat fragmentation are amongst the major drivers of biodiversity loss globally. Although habitat fragmentation poses additional threats to biodiversity beyond habitat loss alone, the IUCN’s Red List of Ecosystems (RLE) does not provide guidance on how to assess these threats. This study develops an approach for incorporating habitat fragmentation into the RLE threat assessment and investigates additional insights such an analysis could provide beyond the analysis of distribution trends. This is achieved by quantifying RLE criteria A and B (distribution reduction, restricted distribution and decline) and comparing outcomes with indices of habitat fragmentation (core area, Largest Patch Index, Patch Cohesion Index and Aggregation Index) in the Cape Floristic Region of South Africa. Results revealed that much of the Cape Floristic Region is severely threatened by both landscape transformation and habitat fragmentation, but that treating the habitat fragmentation indices as additional RLE criteria did not alter the ecosystem threat assessment outcomes. Whilst this suggests that the existing RLE criteria implicitly account for habitat fragmentation, the relationship between fragmentation indices and RLE criteria were weak and highly variable in some cases, indicating that the RLE criteria alone do not sufficiently account for the threat of habitat fragmentation. Supplementing the RLE with habitat fragmentation measures highlights additional, unique information on threats to ecosystems. This simple approach has the potential to assist in setting conservation priorities and management goals, particularly in fragmented ecosystems.

National level use of International Union for Conservation of Nature knowledge products in American National Biodiversity Strategies and Action Plans and National Reports to the Convention on Biological Diversity

AbstractThe Convention on Biological Diversity (CBD) currently serves as the multilateral environmental framework for protecting biodiversity. Parties to the CBD are required to develop and submit National Biodiversity Strategies and Action Plans (NBSAPs) and National Reports. These documents serve as the instruments used by governments and stakeholders to identify their priorities, implement, and track progress to the CBD. The International Union for Conservation of Nature (IUCN) has produced biodiversity and conservation knowledge products that are fundamental for tracking the progress of targets such as the Aichi Biodiversity Targets. We examined if countries in the Americas are using knowledge products based on IUCN standards to help construct their documents; 234 documents were analyzed for knowledge product keywords. The IUCN Red List of Threatened Species was mentioned in 91.8% of keyword‐coded segments. IUCN publications, Protected Areas Categories, Key Biodiversity Areas, the Red List of Ecosystems and World Database on Protected Areas had 8.2% of the remaining segments. Further studies should investigate awareness of knowledge products among national focal points for the CBD to determine their limited use in document development. IUCN knowledge products should continue to form an integral part of future indicators during this critical moment for biodiversity conservation.
