Recommendations

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.

Marine fishes

• Conduct pan-Arctic taxonomic analyses to clarify zoogeographic patterns that are important for detecting and understanding change.
• Establish and conduct a monitoring plan that is independent of fisheries-related programs to assess changes in fish abundance and distributions. Use information from non-commercial fish species caught in groundfish surveys to provide a first step in this direction.
• Use information from TK holders for monitoring marine fishes.
• Connect monitoring initiatives across scales.
• Conduct laboratory studies to examine the possible effects of abiotic and biotic changes (e.g. temperature, salinity, acidity and diseases) on fish species
• Ensure that data on fisheries (commercial as well as artisanal) are accurate and registered in catch databases (such as the Food Agriculture Organisation of the United Nations). Information from logbooks is also relevant as it can be used to estimate the bycatch and the effects of fisheries.

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.

Marine mammals

• Implement existing international monitoring plans such as those for ringed seals and polar bear, with adaptive management principles to address the eleven FEC marine mammal species.
• Expand marine mammal monitoring efforts to include parameters on health, passive acoustics, habitat changes, and telemetry tracking studies.
• Obtain more knowledge about population sizes, densities, and distributions of marine mammal populations in order to understand the relationships between sea ice loss and climate change and to manage Arctic marine mammal populations in an appropriate manner.
• Involve indigenous and local peoples in the design and implementation of monitoring programs so that scientific knowledge and TLK holders are working collaboratively.
• Pursue a multidisciplinary and multi-knowledge approach and a high degree of collaboration across borders and between researchers, local communities and Arctic governments to better understand complex spatial-temporal shifts in drivers, ecological changes and animal health.

The most urgent priorities for the future are to

(i) improve our knowledge of population distributions to better inform our definitions of discrete flyway populations;

(ii) implement effective mechanisms to at least periodically measure abundance for all northern hemisphere goose populations to assess trends over time;

(iii) initiate research to identify factors responsible for declining trends in populations of concern, and

(iv) evaluate potential negative effects of overabundant goose populations on habitat and sympatric species.
