Recommendations

Knowledge gaps: Filling gaps in knowledge helps us better understand key elements and functions of the ecosystem that can help explain change and understand the system:

• Encourage the monitoring of relevant physical parameters alongside some FECs that are particularly sensitive to their effects, including sea ice biota and plankton.
• Expand monitoring programs to include important taxonomic groups and key ecosystem functions. These gaps are likely due to logistical challenges or lack of expertise in specific fields.
• Expand monitoring programs to include those utilizing both TK and science, involvement of Indigenous organizations and build capacity to provide a co-production of knowledge platform.

Sea ice biota

• Establish an annual monitoring programme from land fast sea ice at selected Arctic field stations in Canada (Resolute, Cambridge Bay), Greenland (Kobbefjord, Disko Bay, Zackenberg), Norway (Kongsfjorden, Billefjorden, Van Mijenfjorden), and the U.S. (Barrow).
• Establish a standardized monitoring protocol, including sample collection, preservation, microscopic and genetic analyses, taxonomic harmonization, and data sharing.
• Establish opportunistic monitoring from drifting sea ice during cruises of opportunity.
• Collect macrofauna samples in drifting sea ice via ship-based activities, scuba diving, electrical suction pumps, under-ice trawl nets, and remotely operated vehicles.

Benthos

• Develop a time- and cost-effective, long-term and standardized monitoring of megabenthic communities in all Arctic regions using regular national groundfish assessment surveys. Expanding monitoring on micro-, meio- and macrobenthic groups is encouraged.
• Gather information from research programs in regions without regular groundfish-shellfish trawl surveys. These are usually short-term and do not guarantee spatial consistency in sampling, but provide valuable information on benthic biodiversity and community patterns.
• Generate information on benthos from little-known regions, such as the Arctic Basin and Arctic Archipelago, on cryptic or difficult taxonomic groups, and on biological “hotspots”.
• Systematic studies of macrobenthos (grab investigations) and megabenthos (trawl bycatch of regular fishery surveys including both annual studies, as in the Atlantic Arctic, and periodic studies as in the Northern Bering and Chukchi Seas) are the most suitable and practical approach to long-term monitoring.
• Standardize methodology, including taxonomic identification, across regions to assist in regional comparisons.
• Recognize and support the use of TLK as an invaluable resource for understanding of changes in Arctic benthic communities.

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.

Indigenous Knowledge: The CBMP Terrestrial Plan aims to utilize both Indigenous Knowledge and science. Despite efforts, Indigenous Knowledge has not been systematically included in the START. To obtain a full assessment of the status and trends, better understand relationships and changes, and fill key knowledge gaps, there must be improved engagement with Indigenous Knowledge holders, Indigenous governments, and Indigenous monitoring programs not only in development of assessments but in collaboratively building more comprehensive monitoring programs and initiatives.

• Improve understanding of the research and monitoring priorities of PPs and Indigenous governments, organizations, and Peoples.
• Develop long-term partnerships between scientists and Indigenous Knowledge holders to co-develop mutually relevant research and monitoring priorities and programs with equitable participation in all stages of monitoring, beginning with research design, and continuing through implementation, analysis, interpretation, and communication of results.
• Seek guidance on how institutional resources can align with and support existing Indigenous-led monitoring efforts, the development of new Indigenous-led monitoring programs, and Indigenous models of land stewardship that include monitoring components.
• Consider and articulate the ways in which programs and findings can support Indigenous land stewardship.
• Support Indigenous-led monitoring capacity through investments in northern-based research, learning and digital infrastructure and by supporting education, employment, and leadership opportunities for Indigenous Peoples.
• Ensure monitoring agreements detail mechanisms for the protection and responsible use of data and Indigenous Knowledge, including basic principles of data sovereignty.
• Increase engagement of Indigenous Peoples within CBMP.
• Work with PPs to develop strategies to more effectively recognize and reflect Indigenous Knowledge in the CBMP.

Knowledge Gaps : Currently, there is some monitoring for all FECs, but it varies in coverage, duration, frequency and access to institutional support and resources.

• Expand and coordinate long-term in situ time series across regions and across FECs.
• Implement ecosystem-based approaches that better monitor and link biological attributes to environmental drivers.
• Increase partnerships with Indigenous Knowledge holders and organizations.
• Increase and support contributions from Local Knowledge holders and citizen science.
• Work with Arctic Council Observer states to collect and compile knowledge on Arctic biodiversity.
• Improve data collection on rare species and species of concern.

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.
