coastaltundra

Coastal tundra refers to a specific type of treeless biome found along the coastlines of Arctic and sub-Arctic regions. Unlike inland tundra, coastal tundra is heavily influenced by the proximity to the ocean. This maritime influence typically results in slightly milder temperatures, higher precipitation, and greater humidity compared to interior tundra. The soil in coastal tundra is often permafrost, meaning it remains frozen for most of the year, limiting the depth to which plant roots can penetrate.

Vegetation in coastal tundra is characterized by low-growing plants adapted to the harsh conditions. This includes mosses, lichens, sedges, grasses, and dwarf shrubs like willows and birches. The growing season is short, and plants must be able to withstand strong winds, salty air, and the freezing and thawing cycles of the permafrost. Wildlife in coastal tundra often includes migratory birds that breed in the area during the warmer months, as well as marine mammals like seals and walruses that utilize the coastline for foraging and resting. Reindeer and Arctic foxes are also common inhabitants. The landscape can be varied, with areas of bog, marsh, and rocky shores. These unique ecosystems play a vital role in the Arctic food web and are sensitive to changes in climate.
