Abstract

The North American Boreal Forest biome has been recognized as containing some of the highest proportions of intact, primary forest left on Earth. Over 6 million km² of the Boreal Forest biome is found in Canada (5.5 million km²) and the U.S. (0.74 million km²) across 10 provinces and territories and one U.S. state (Alaska). All of it is within the traditional territories of hundreds of Indigenous governments, many of whom are now asserting their rights to make decisions about its future and current land-use including for conservation and development. The biome is considered to be 80% intact and between 8% and 13% formally protected. The North American Boreal Forest biome’s intactness has allowed it to retain many globally significant conservation features including long-distance mammal and fish migrations, healthy populations of large predators, one to three billion nesting birds, some of the world’s largest lakes and North America’s longest undammed rivers, massive stores of carbon and ecological functionality. The biome’s forests, minerals, and hydropower potential are also recognized as economic opportunities so that the industrial footprint is rapidly increasing, sometimes without careful land-use planning decisions. Indigenous, federal, state, provincial and territorial governments and conservation organizations have strived over recent decades to recognize the conservation opportunity inherent in such a still-intact landscape, resulting in implementation of some of the world’s largest land conservation set-asides. Indigenous governments, in particular, have been at the forefront in developing and implementing world-leading, modern land-use plans that achieve land conservation at massive scales. Supporting efforts to ensure that a high proportion of North America’s Boreal Forest biome is protected and remains as intact habitat with unimpeded ecosystem processes should be a priority of the global conservation community. Federal, state, and provincial/territorial governments should support Indigenous protected area proposals, vastly increase financial support for Indigenous government land conservation and stewardship activities, and should develop new protected area co-management models with Indigenous governments. Governments should also be strongly advocating for raising the global Convention on Biological Diversity protected area goal to at least 30% by 2030.

Highlights

  • With the advent of GIS capabilities and the availability of complete global coverage of remote sensing products over the last two decades, identification of the biomes of the world with the least large-scale human impacts has become possible

  • First identified in 1997 (Bryant et al, 1997) and termed “frontier forests” these forest areas have subsequently been mapped under different criteria and terms including “wilderness,” “intact forest” and “primary forest” in a number of other publications and analyses (Sanderson et al, 2002; Mittermeir et al, 2003; Potapov et al, 2008, 2017; Hansen et al, 2013; Mackey et al, 2014; Watson et al, 2016, 2018; Dinerstein et al, 2017)

  • The areal extent of the North American Boreal Forest biome is predicted to shrink by 25% by the end of the century (Rehfeldt et al, 2012)

Summary

INTRODUCTION

With the advent of GIS capabilities and the availability of complete global coverage of remote sensing products over the last two decades, identification of the biomes of the world with the least large-scale human impacts has become possible. The biggest anthropogenic challenges, other than climate change, for Alaska’s Boreal Forest biome, come from proposed development projects that include infrastructure for large-scale mining operations and access to currently roadless landscapes Some of these projects will threaten the ecological integrity of existing protected areas (Wilson et al, 2014). The dam created by the project would be the fifth largest concrete dam in the world Proposed dams and both claimed and surveyed mining claims encompass a significant portion of Alaska’s Boreal Forest, indicating the potential for large-scale industrial development in a currently intact ecological region larger than the size of California. Several recent publications have outlined the regions within the Boreal Forest biome that are predicted to be important future climate change refugia for a variety of wildlife and plants and the factors that are important in determining what areas will show rapid change and what areas will show slower changes (Stralberg et al, 2018, 2020a,b)
