Tundra Ecosystem
The tundra ecosystem is a vast, treeless region that spans across the northernmost parts of the world, including parts of Alaska, Canada, Russia, and Scandinavia.
Climate
The tundra has a cold and harsh climate, with long winters and short summers. The average temperature is below freezing for most of the year.
Plants
Despite the challenging conditions, the tundra is home to a variety of plants adapted to the environment, including mosses, lichens, and dwarf shrubs.
Animals
The tundra is also home to a variety of animals, including caribou, musk oxen, arctic foxes, and polar bears. Many of these animals have special adaptations to help them survive in the cold climate.
Threats to the Tundra Ecosystem
The tundra ecosystem is facing a number of threats, including climate change, oil and gas exploration, and overgrazing by reindeer and other animals.
Conservation Efforts
There are several conservation efforts underway to protect the tundra ecosystem, including efforts to reduce greenhouse gas emissions and protect areas from development.
