Alpine zones at the highest elevations support specialized vegetation adapted to extreme conditions, including dwarf shrubs, grasses, and alpine wildflowers. Endemic species such as the Appalachian cottontail and the Appalachian brook trout are found in these high-altitude habitats, contributing to the region’s biodiversity and serving as indicators of ecosystem health.

The Caledonian Mountains, spanning across Scandinavia, the British Isles, and Eastern Greenland, boast a diverse range of ecological zones shaped by glacial processes, geological formations, and climatic gradients. In Norway, the rugged fjords and high plateaus support a mosaic of habitats, including boreal forests, mountain tundra, and alpine meadows.

The boreal forests of Norway and Sweden are dominated by coniferous species such as pine, spruce, and fir, interspersed with wetlands, lakes, and rivers. These forests provide critical habitat for species such as moose, reindeer, and brown bears, as well as a variety of migratory birds that rely on these ecosystems during their annual migrations.

At higher elevations, mountain tundra and alpine ecosystems prevail, characterized by sparse vegetation, rocky outcrops, and glaciers. Arctic foxes, ptarmigans, and lemmings are among the species adapted to these harsh environments, where short growing seasons and extreme weather conditions pose significant challenges for survival.

The Iberian Peninsula and its Variscan Mountains boast a rich tapestry of ecological zones influenced by Mediterranean climate, topography, and human activity. Along the Mediterranean coast, dry scrublands and maquis vegetation dominate the landscape, characterized by species such as cork oak, olive, and lavender.

Inland, the Iberian Peninsula features a mix of Mediterranean forests, cork oak savannas, and montane woodlands, supporting a rich diversity of plant and animal life. Endemic species such as the Iberian lynx, Spanish ibex, and Iberian wolf are found in these habitats, highlighting the region’s ecological significance and conservation value.

In the Pyrenees mountain range, which forms the natural border between Spain and France, montane ecosystems give way to alpine meadows, rocky slopes, and glacial lakes. These high-altitude habitats provide refuge for species such as the Pyrenean chamois, griffon vulture, and golden eagle, contributing to the biodiversity and ecological resilience of the region.

Morocco, situated in North Africa, boasts a diverse range of ecological zones influenced by the Atlas and Anti-Atlas Mountains, Sahara Desert, and Atlantic coastline. Along the Atlantic coast, coastal dunes, wetlands, and mangrove forests provide habitat for a variety of bird species, including flamingos, herons, and terns.

Inland, the Atlas and Anti-Atlas Mountains are characterized by a mix of Mediterranean forests, cedar woodlands, and high-altitude plateaus. Endemic species such as the Barbary macaque, Atlas bear, and Atlas deer are found in these habitats, which are also home to a variety of plant species adapted to arid and semi-arid conditions.

In the Sahara Desert, which occupies much of southern Morocco, sparse vegetation, sand dunes, and rocky plains dominate the landscape. Desert-adapted species such as the dromedary camel, fennec fox, and Saharan horned viper are among the inhabitants of this harsh environment, where extreme temperatures and limited water resources shape ecological dynamics.

Throughout the ecological zones of the Appalachian-Caledonian Orogeny, a complex web of interactions between species, ecosystems, and geological processes shapes the distribution and abundance of life. Migration, dispersal, and colonization play key roles in shaping biodiversity patterns, with species adapting to environmental gradients and ecological niches.

However, these ecological zones face numerous conservation challenges, including habitat loss, fragmentation, climate change, and invasive species. Human activities such as deforestation, urbanization, and industrial development threaten the integrity of ecosystems and the survival of many species. Conservation efforts are critical for preserving the ecological diversity of the Appalachian-Caledonian Orogeny and ensuring the long-term sustainability of its natural resources.
