- 1. Norwegian tundra ecosystems are characterized by their harsh and unforgiving environment, with low temperatures, strong winds, and minimal precipitation. The landscape is dominated by vast expanses of treeless tundra, scattered with low shrubs, mosses, and lichens. Despite the challenging conditions, these ecosystems support a diverse range of wildlife, including reindeer, arctic foxes, and migratory birds. The fragile balance of life in the Norwegian tundra is threatened by climate change, with rising temperatures affecting the availability of food and habitat for many species. Conservation efforts are underway to protect this unique and valuable ecosystem for future generations.
