How do we steward #forests & #borderlands in a time of human upheaval & migration? Not by building border walls. Our letter @ScienceMagazine about how Poland’s planned wall would threaten transboundary #Białowieża Forest @MZmihorski @UNESCO @BonnConvention science.org/doi/10.1126/sc…
Transboundary frontiers are an emerging conservation priority as they often overlap #biodiversity hotspots & are threatened by construction of border infrastructure. Neighboring countries must co-steward wildlife that cross manmade lines @EcologyJiajia sciencedirect.com/science/articl…
We know from research on the US-Mexico border that walls do not deter people but do impede wildlife, including low-flying birds like pygmy owls. Barriers are an increasing global trend that fragment #connectivity of habitats & populations @ljevanso academic.oup.com/bioscience/art…
That "conservation biologists increase their presence and profile in national and international debates surrounding border security fencing" is recommended by @johndclinnell et al. in an era of both border fences and a transboundary conservation paradigm. journals.plos.org/plosbiology/ar…
A razor-wired fence, constructed in 2015 by Slovenia along its border with Croatia, killed deer and herons. The mortality rate documented by Boštjan Pokorny et al. was 0.12 ungulates/km of fence. Such data—on effects of border fences on wildlife—are scant. link.springer.com/article/10.100…
Expert @ProfVallet lays out the costs of #BorderWalls. Beyond the financial, walls come at the price of international relations, local economies, and human safety and lives, as traffickers seek out alternative, often more dangerous and clandestine routes. theconversation.com/border-walls-a…
New frameworks & better understanding are being talked & written about. On my list: Border & Rule @HarshaWalia, & The Next Great Migration @soniashah. As @johnrplatt & others stress, "#ClimateChange threatens to disrupt borders & migratory patterns of people & wildlife". #NoWalls 
According to a recent UN report, some World Heritage forests are now releasing more carbon than they absorb. #Białowieża Forest is still among the healthy @UNESCO #WorldHeritage forests and carbon sinks. news.un.org/en/story/2021/…
Poland’s planned border wall would not only block large mammal movements and prevent recolonization by brown #bears of the Polish side of #Białowieża Forest, wall construction risks #PlantInvasions, and means noise & light pollution, & militarization. sciencedirect.com/science/articl…
