A landmark one-week meeting concluding late last month in Campo Grande, Brazil, saw governments, non-governmental organizations, Indigenous Peoples representatives, and international bodies forge new, strengthened commitments aimed at safeguarding migratory birds and other species across the globe. The 15th Conference of the Parties (COP15) to the Convention on Migratory Species (CMS), hosted in the gateway city to the vast Pantanal wetland, served as a crucial platform for concerted international action on species management and habitat preservation.
The Significance of the Convention on Migratory Species
The Convention on the Conservation of Migratory Species of Wild Animals, often referred to as the Bonn Convention, is an international treaty under the aegis of the United Nations Environment Programme (UNEP) that aims to conserve migratory species and their habitats worldwide. Established in 1979 and entering into force in 1983, CMS recognizes that many species migrate across national boundaries, rendering national conservation efforts insufficient. Its mandate is to provide a global legal framework and a platform for international cooperation for the conservation and sustainable use of migratory animals and their habitats.
Migratory species, from majestic whales and elusive big cats to countless bird species and insects, play vital ecological roles, acting as indicators of ecosystem health, facilitating pollination and seed dispersal, and contributing to nutrient cycling. However, they face a disproportionate array of threats due to their reliance on a network of habitats spanning multiple jurisdictions. Habitat loss and degradation, climate change, pollution, unsustainable hunting, infrastructure development, and bycatch in fisheries all conspire to push many migratory populations towards decline, with some teetering on the brink of extinction. CMS COP15 therefore represented a critical juncture for nations to address these escalating pressures.
The choice of Campo Grande, situated at the edge of the Pantanal, one of the world’s largest tropical wetland areas renowned for its incredible biodiversity, was highly symbolic. The region itself is a crucial migratory stopover and breeding ground for numerous bird species, offering delegates a constant, living reminder of the stakes involved in their deliberations. Observers noted the frequent presence of iconic local birds such as Blue-and-yellow Macaws and Burrowing Owls, underscoring the immediate relevance of the conservation efforts being debated.
Intensive Deliberations and Key Agenda Items
The week-long conference was characterized by intensive negotiations, with delegates frequently working long into the night. The agenda was comprehensive, focusing on several critical areas of migratory species conservation. A primary objective was the "listing" of additional migratory species under the CMS Appendices, which categorizes species requiring strict protection (Appendix I) or those needing international cooperation for their conservation (Appendix II). This process involves rigorous scientific assessment of population declines, threats, and conservation needs.
Beyond species listings, significant attention was directed towards mitigating specific, pervasive threats. The risks posed by poisoning, particularly from lead ammunition and veterinary drugs, which can have devastating secondary impacts on scavengers, were thoroughly discussed. Another critical concern was unintentional seabird bycatch from commercial fishing operations, a phenomenon responsible for the deaths of hundreds of thousands of seabirds annually, including many critically endangered albatrosses and petrels. Furthermore, delegates explored strategies to enhance coordination and cooperation along the world’s major avian flyways, recognizing that effective conservation requires seamless, transboundary management.
The Audubon delegation, in collaboration with government officials and BirdLife Partners, played a pivotal role in shaping the outcomes. Their efforts concentrated on reinforcing protections for migratory birds globally and championing cooperative action across the Americas’ flyways. This strategic engagement aimed to advance two crucial partnerships designed to yield tangible results for avian conservation throughout the Western Hemisphere. The successes achieved during the conference reflect a growing international resolve to tackle these complex environmental challenges.
Consolidating Support for Conserva Aves in Brazil
One of the significant highlights of CMS COP15 was the consolidation of strong support for Conserva Aves, a groundbreaking initiative aimed at protecting critical bird habitats across Latin America and the Caribbean. Through a well-attended public event and a dedicated technical working session, Audubon, BirdLife International, and their Brazilian partners, SAVE Brasil and FUNBIO (Brazilian Fund for Biodiversity), effectively showcased Conserva Aves as a proven model with immense potential. The initiative’s core objective is the creation, expansion, and robust implementation of protected areas specifically designed to safeguard bird habitat in Brazil, a country boasting unparalleled biodiversity.
Brazil is home to approximately 1,900 bird species, representing nearly 20% of the world’s avian diversity. Many of these species are endemic or rely on vast migratory corridors within and beyond its borders. The enthusiastic reception from the Brazilian government for Conserva Aves is therefore particularly encouraging. Officials expressed keen interest, offering access to valuable technical and spatial data, and engaging in detailed discussions about the initiative’s alignment with Brazil’s national policy objectives and existing environmental programs. This strong governmental endorsement provides a critical foundation for the initiative’s long-term success. The Conserva Aves partners are now poised to finalize the design phase, meticulously working to optimize opportunities for bird conservation within this megadiverse nation. This includes identifying priority areas for protection, developing sustainable management plans, and fostering community engagement, ensuring that conservation efforts are both ecologically effective and socially equitable.
Strengthening Cooperation Along America’s Flyways
Another monumental outcome of the Campo Grande meeting was the decision by governments to establish the CMS Americas Flyways Initiative. This pivotal step aims to significantly strengthen the institutional framework for conservation and enhance the coordination of actions along the vast migratory pathways of the Americas. Recognizing that migratory birds traverse multiple countries during their annual cycles, effective conservation necessitates a harmonized approach that transcends national borders.
The Americas Flyways Initiative, made possible through the dedicated leadership of governments from Brazil, Costa Rica, and Uruguay, was formally captured in a COP15 Resolution and Decision. This new initiative is designed to be inclusive, open to participation from all governments in the Americas, as well as other key stakeholders, including scientific bodies, Indigenous communities, and conservation organizations. The offer by Audubon and BirdLife International to provide crucial support for the coordination and implementation of the initiative was met with warm appreciation, highlighting the vital role of civil society in driving such multilateral efforts.
The Americas boast four major flyways—the Atlantic, Mississippi, Central, and Pacific—which are used by billions of birds representing hundreds of species. These flyways connect diverse ecosystems, from the Arctic breeding grounds to the Patagonian wintering areas, making coordinated action along their entire lengths absolutely indispensable. The new initiative presents an unprecedented opportunity to galvanize governmental and stakeholder action, not only to protect migratory birds and conserve their critical habitats but also to foster better coordination of efforts across entire flyways. This framework promises to facilitate data sharing, joint monitoring programs, and collaborative policy development, leading to more resilient and effectively managed migratory bird populations.
Advancing Global Protections for Migratory Birds
Beyond regional initiatives, CMS COP15 also yielded several crucial Resolutions and Decisions focused on strengthening protections for migratory species worldwide, encouraging robust conservation measures, and directly addressing persistent risks. A significant achievement was the formal "listing" of several species of high conservation concern, recognizing their urgent need for additional protective measures. These included the Lesser Yellowlegs, Hudsonian Godwit, and Hudsonian Whimbrel – all shorebirds that are central to the conservation efforts of Audubon and its partners across the Americas.
The Lesser Yellowlegs (Tringa flavipes), a medium-sized shorebird, breeds in boreal forests of North America and migrates to coastal and inland wetlands of Central and South America. Its populations have shown significant declines, primarily due to habitat loss and degradation at crucial stopover sites. The Hudsonian Godwit (Limosa haemastica), known for its incredibly long-distance migration from Arctic Canada and Alaska to southern South America, faces similar threats, including climate change impacts on its fragile Arctic breeding grounds and habitat alteration in its non-breeding range. The Hudsonian Whimbrel (Numenius hudsonicus), another long-distance migrant, breeding across the North American tundra and wintering along coastlines from California to Chile, is vulnerable to hunting pressures and habitat destruction. Listing these species under CMS means that signatory nations are now obliged to implement stricter conservation measures within their territories to ensure the survival of these iconic migratory birds.
Marine flyways also received dedicated attention during COP15, underscoring the global interconnectedness of ecosystems. The language within CMS resolutions pertaining to bycatch from fisheries was broadened to encompass "migratory" species in general, rather than being restricted to specific groups. This seemingly subtle change is profound, as it will promote the systematic inclusion of seabirds within national measures designed to reduce accidental catch by fishing boats across various fisheries sectors. Seabird bycatch is a major driver of population declines for many species, with estimates suggesting hundreds of thousands of albatrosses, petrels, and shearwaters are killed annually. The broadening of this language provides a stronger international mandate for nations to implement mitigation strategies such, as weighted lines, bird-scaring devices (tori lines), and night setting.
Furthermore, parties encouraged greater coordination across marine flyways, specifically referencing and endorsing efforts such as the Agreement on the Conservation of Albatrosses and Petrels (ACAP). ACAP, a separate multilateral agreement, focuses on reducing threats to albatrosses and petrels, species that undertake vast oceanic migrations and are particularly vulnerable to longline fishing. The CMS endorsement strengthens the global framework for marine bird conservation, fostering synergy between various international instruments.
Broader Impact and Future Implications
Despite the late nights and the often-esoteric nature of text negotiations, CMS COP15 stands as a powerful testament to the fact that policymakers, scientists, and other experts from diverse backgrounds can indeed converge to shape a better future for migratory species. The conference demonstrated a clear international political will to address biodiversity loss, particularly for species that do not recognize political boundaries.
The outcomes of COP15 are expected to have far-reaching implications. The strengthened mandates for species protection and habitat conservation align closely with the ambitious targets set forth in the Kunming-Montreal Global Biodiversity Framework (GBF), adopted at COP15 of the Convention on Biological Diversity (CBD) in late 2022. The GBF calls for protecting 30% of land and sea by 2030 and halting human-induced extinction of threatened species. The CMS decisions contribute directly to achieving these global goals, providing specific pathways for action for migratory fauna.
However, the true measure of success for CMS COP15 will lie in the effective implementation of these resolutions and decisions at national and regional levels. This will require sustained political commitment, adequate financial resources, robust monitoring programs, and continued scientific research. Challenges such as ensuring compliance across diverse national legal frameworks, securing consistent funding for conservation initiatives, and adapting to rapidly changing environmental conditions (particularly climate change) will need to be proactively addressed.
The active participation of non-governmental organizations like Audubon and BirdLife International, coupled with the crucial insights from Indigenous Peoples representatives, underscores the growing recognition that multi-stakeholder collaboration is indispensable for effective conservation. Their ability to bridge scientific data with policy advocacy and community engagement is vital for translating international agreements into on-the-ground conservation success.
In conclusion, the CMS COP15 in Campo Grande represents a significant step forward in the global effort to conserve migratory species. The new commitments for Conserva Aves, the establishment of the Americas Flyways Initiative, and the enhanced protections for critically important species like the Lesser Yellowlegs, Hudsonian Godwit, and Hudsonian Whimbrel, along with broader measures against bycatch, offer a renewed sense of hope. Now, the collective responsibility shifts to governments, organizations, and communities worldwide to work tirelessly, ensuring these resolutions translate into meaningful and lasting benefits for all migratory birds and the ecosystems they depend on for their futures.
