Abstract
Climate change presents a complex set of challenges for natural resource managers across North America. Despite recognition that climate change poses serious threats to species, ecosystems, and human communities, implementation of adaptation measures is not yet happening on a broad scale. Among different regions, a range of climate change trajectories, varying political contexts, and diverse social and ecological systems generate a myriad of factors that can affect progress on climate change adaptation implementation. In order to understand the general versus site-specific nature of barriers and opportunities influencing implementation, we surveyed and interviewed practitioners, decision-makers, and scientists involved in natural resource management in four different North American regions, northern Ontario (Canada), the Adirondack State Park (US), Arctic Alaska (US), and the Transboundary Rocky Mountains (US and Canada). Common barriers among regions related to a lack of political support and financial resources, as well as challenges related to translating complex and interacting effects of climate change into management actions. Opportunities shared among regions related to collaboration, funding, and the presence of strong leadership. These commonalities indicate the importance of cross-site learning about ways to leverage opportunities and address adaptation barriers; however, regional variations also suggest that adaptation efforts will need to be tailored to fit specific ecological, political, social and economic contexts. Comparative findings on the similarities and differences in barriers and opportunities, as well as rankings of barriers and opportunities by region, offers important contextual insights into how to further refine efforts to advance adaptation actions in those regions.Entities:

Fig. 1Four North American conservation landscapes selected for this study
Comparison of key factors across four priority conservation landscapes
| Arctic Alaska | Yellowstone Rockies | Adirondack Park | Ontario’s Northern Boreal | |
|---|---|---|---|---|
| Rate and immediacy of climate change | Average annual temperature has increased ~0.5 °C/decade since 1949. | Average annual temperature has increased ~0.3 °C/decade since 1951. | Average annual temperature has increased ~0.2 °C/decade since 1951. | Average annual temperature has increased as much as 1.3 °C since 1949. |
| Future temperature increases projected to be the most rapid and of the greatest magnitude. | Future temperature increases projected to be higher than global averages. | Future temperature increases projected to be higher than global averages. | Warming and precipitation are expected to increase in the future, particularly in winter. | |
| Likely availability of future refugia for current species and ecosystems | Arctic systems cannot move further poleward, or up in elevation, if conditions in current locations become unsuitable. | Yellowstone Rockies are a mix of species and ecosystems at their southern and northern edges, and the center of their distributions. | The Adirondack Park lies at the transition between southern cool-temperate forests, and northern boreal forests so shifts between these ecosystem types are likely. | If conditions in current locations become unsuitable, sub-arctic systems may be able to move further poleward, across the James and Hudson Bay, but not up in elevation due to a lack of topographic diversity. |
| Future refugia within the Arctic contingent on identifying relatively fine-scale climate refugia (e.g., fog-bound coastal areas). | Topographic diversity may allow for higher elevation refugia; species and ecosystems may find refuge at higher latitudes. | Refugia may exist for boreal species further north, but it is unclear whether all species will be able to move there. | ||
| Relative degree of internal ecological integrity and isolation | Highly intact with little development to date. | Relatively intact both internally, and with other large core protected areas. | Relatively intact within the Adirondack Park, but relatively isolated from other large core protected areas. | Highly intact with little development to date. |
| Biggest current threat to ecological integrity is mining and energy development. | Biggest current threats to ecological integrity are changing land use and human population growth. | Biggest current threat to ecological integrity is private land development. | Biggest current threat to ecological integrity is mining, energy development and uncertainty in government-to-government negotiations. | |
| Political context | Mix of primarily federal lands, native lands (scattered low density villages), and state lands. | Mosaic of largely federal and private lands, under federal, state, and county jurisdictions. | Mostly publically-owned state and private land, with land use regulated by the Adirondack Park Agency, in coordination with other agencies. | Treaty 9 (1905/06, 1929/30), Crown land (Provincial and Federal, includes 34 First Nation reservations). |
