Recommendations

Coordination: Better coordination allows for increased value for investment in monitoring programs, better opportunity to compare results, and more ability to draw meaningful conclusions from data:

• Strategically locate Arctic research stations and monitoring vessels, and use all collected specimens, to allow the collection and analysis of as many CBMP FECs as possible.
• Ensure research stations operate all year to better study FECs year round.
• Combine national monitoring with collaborative approaches that allow for sufficient integration and standardization to conduct syntheses across the circumpolar region.
• Standardize how data are collected, managed and made available. This is a key component in ensuring circumpolar Arctic comparability and should be an important consideration in the implementation of monitoring plans.
• Encourage states to increase the implementation of existing internationally coordinated monitoring plans.
• Connect monitoring initiatives and report across scales so that results are meaningful for local, sub-national, national, regional and global decision-makers.
• Continue to increase coordination between CBMP and other regional and global monitoring initiatives e.g., the Group on Earth Observations Biodiversity Observation Network (GEOBON), International Council for the Exploration of the Sea (ICES) and the Intergovernmental Platform on Biodiversity and Ecosystem Service (IPBES).

Seabirds

• Develop methods for assessing diet to increase our understanding of changes in the ecosystem and how they affect seabird populations.
• When selecting sites for new monitoring, consider proximity to hotspots for marine activities, access to the sea, and inclusion of plankton monitoring.
• Expand colony-based monitoring and strive to include a more complete array of parameters, in particular, diet and measures of survival.
• Consider a higher frequency of monitoring as current levels make it difficult to identify mechanisms or causes of change in populations.
• Conduct targeted surveys and individual tracking studies of seabird interactions at sea to improve our understanding of seabird interactions at sea, where seabirds spend most of their time.
• Continue to conduct at sea surveys on an opportunistic basis.

Traditional and Local Knowledge (TLK): Utilizing Traditional and Local Knowledge and involvement of TK holders allows for increased understanding of relationships and changes underway in Arctic ecosystems, current and historical trends, and serves to build valuable partnerships on the ground in Arctic communities.

• Use Traditional and Local Knowledge within the design and implementation of monitoring plans. The Traditional and Local Knowledge of people living along and off the Arctic Ocean is an invaluable resource for understanding changes in Arctic marine ecosystems and its inclusion should be supported by national governments.
• Increase engagement and partnerships with local residents and easy to access technology in monitoring programs. Indigenous communities are important ‘first responders’ to catastrophic events. More importantly, their knowledge systems provide a wealth of knowledge that should be involved in the analysis of collected data for increased understanding of current trends and filling historical gaps.
• There is a need for TLK on a range of FECs and to engage networks of TLK holders and Indigenous organisations.
• Use both TLK and scientific information on the analysis of harvest levels and status when evaluating overall population health and managing hunts.

Community-based monitoring networks and community relationship building:

• Increase the span of networks in the CBMP to include Community-based monitoring networks.
• Communicate information on changes and the results of monitoring between scientists and the public in both directions. This is crucial to the development of effective management strategies and human activities.

Arthropods : Arthropods are highly diverse and under-studied. They serve as important connections between trophic levels and several are important indicators of changing environments. The START reports on six FECs: pollinators, decomposers, herbivores, prey for vertebrates, blood-feeding insects, and predators and parasitoids. Only a few localized trends are provided due to high variability and lack of monitoring.

• Implement long-term sampling programs at strategic sites with rigorous standardized trapping protocols.
• Collect baseline data, including structured inventories, using standardized protocols for FECs and key attributes.
• Work with Indigenous Knowledge holders, Local Knowledge holders, and/or citizen science to identify regionally important species to monitor, and key locations for long-term monitoring activities.
• Focus monitoring efforts on taxa that: (a) are well-studied with existing data; (b) respond to, or are vulnerable to, change; and/or (c) have possible range shifts. • Monitor dominant habitats at a variety of sites at both small and large geographic scales.
• Monitor relevant microhabitat environmental parameters, in addition to climatological variables, and connect to biological trends at relevant scale.
• Focus on critical FEC attributes, including ecosystem processes such as pollination, decomposition, and herbivory.
• Continue specimen sorting, identification and reporting and construct a complete trait database.
• Complete molecular sequence libraries, increase international collaboration to collate, analyze, archive, and make data accessible.

Ecosystem-based Monitoring and Reporting: Monitoring and reporting should encompass all key taxonomic groups and their likely relationships, linking responses to main biotic and abiotic drivers of change.

• Better coordinate between disciplines and knowledge systems both within and among Arctic states and Indigenous organizations, including experts in abiotic drivers of change (the Arctic Monitoring and Assessment Program) and other monitoring initiatives.
• Promote long-term integrated studies across biomes and taxonomic groups for examining trophic dynamics and other key interactions.
• Improve integration of factors that underpin changes in phenology, demography, and abundance.

Mammals: The START reports on half of mammal FECs including large herbivores (caribou/reindeer, muskoxen), small herbivores (lemming), and medium-sized predators (Arctic fox). Data deficiencies prohibited reporting on medium-sized herbivores, and large and small predators.

• Develop synchronized protocols that include more attributes and reduce geographical knowledge gaps.
• Establish or expand international monitoring networks for medium-sized herbivores and large and small carnivores.
• Emphasize spatial structure and diversity in monitoring efforts due to the northward advance of southern competitors and vegetation changes.
• For large herbivore, small herbivore, and medium-sized predator FECs:
• Agree on priorities and harmonize data collection across sites and programs;
• Share and standardize protocols, in cooperation with relevant partners including Indigenous Peoples and organizations, to include abundance, demographics, spatial structure, health, phenology and, for harvested species, harvest rates; and
• Ensure monitoring programs employ existing methods with new harmonized methods to allow data comparisons.
• Monitor health as an attribute and develop standardized health assessment protocols due to the anticipated impact of climate change on distribution and prevalence of disease.
• Monitor abiotic factors and drivers of change, across greater spatial distributions to assess the cumulative impacts of climate and other anthropogenic change on populations across their ranges.
• Conduct research on the vulnerabilities of populations to climate change and human impacts, and on genetic diversity and spatial structure of FECs.
• Increase collaboration using interdisciplinary and multi-knowledge approaches to share site- and population-specific information. This can improve monitoring and lead to better models to assess the vulnerabilities and resilience of specific populations.
• Address challenges in assessing abundance of FECs across the Arctic, including:
• reliability of abundance estimates, such as lack of precision and accuracy;
• changing baselines, such as changes in species distribution, sampling methodology, and areas monitored; and
• differences in frequency and spatial extent of monitoring.

Methods : Increased attention to methodology facilitates more precise and comparable results, standardized data collection, and ability to link regional monitoring to circumpolar efforts.

• Standardize how data is collected, managed, and reported, including field and sampling protocols, data collection methods, terminology, database harmonization and management, tools for data archiving and specimen libraries, including identification and curation.
• Create a harmonized, accessible, and long-term taxonomic framework for Arctic monitoring.
• Complete baseline studies and structured inventories to improve circumpolar data across FECs.
• Promote multi-species studies and long-term time series data.
