Threatened boreal dry scrub habitats

Background

The global significance of threatened boreal dry scrub habitats emerged in the late 20th century, as ecologists documented their rapid decline across northern Eurasia and North America. Initial attention arose from studies linking habitat loss to rare species declines and altered fire regimes. Subsequent international assessments, such as those by the Circumboreal Vegetation Map project, highlighted the unique vulnerability of these ecosystems, prompting increased conservation focus and cross-border research collaborations.
