Belgium

Belgium's biodiversity reflects its position at the crossroads of Atlantic, Continental, and Alpine biogeographical regions. The country's compact territory encompasses diverse ecosystems including the Ardennes forests, Flemish coastal dunes, Kempen heathlands, and extensive river valleys of the Scheldt and Meuse. Despite its small size, Belgium supports significant populations of migratory birds along the East Atlantic Flyway and harbors endemic invertebrate species in its ancient forest fragments and limestone caves. The IUCN Red List 2025 data reveals an alarming situation: all 62 assessed species are threatened, with every single species classified as Critically Endangered. This unprecedented threat level reflects Belgium's position as one of Europe's most densely populated and industrialized nations. Urban sprawl fragments the remaining 23% forest cover, while intensive agriculture dominates 45% of the landscape. The Flemish Region faces particular pressure from port expansion around Antwerp and Zeebrugge, threatening coastal wetlands crucial for waterbirds. Nitrogen deposition from agriculture and industry severely impacts the Kempen's unique heathland ecosystems. River systems suffer from historical channelization and ongoing pollution, affecting freshwater biodiversity. Climate change compounds these pressures, with rising sea levels threatening the narrow coastal zone and shifting precipitation patterns affecting the Ardennes montane ecosystems.
