Stay warm. Tundras have very cold climates, with an average of -18 degrees Fahrenheit, so the first order or business is avoiding hypothermia. Dress as warmly as possible, avoid getting wet and if possible, build a fire. Use branches from birch and willows that grow sparsely in the Tundra biodome.
Find shelter. Winds in a tundra can blow between 30 to 60 miles per hour, which can make it all the harder for you to keep warm. Thus, it's important to find shelter. Look for a large, rocky structure to hide behind. A sturdy tent with long stakes digging into the ground can help keep the elements at bay. If necessary, create a snow cave or snow trench.
Stay hydrated. Melted snow will do in a pinch if you have no drinking water. If it rains, collect the water, as precipitation in a tundra is scarce. During the Arctic summer, when the snow on the surface melts, water can be found in the lakes and marshes that form.
Find nourishment. The rocky, frozen terrain of a tundra can only support low-growing plants, such as lichen, heaths and mosses. However, you can find insects, migrating birds and about 48 species of land mammals, including hares, rodents and deer. A book containing a list and description of edible plants in this part of the world, as well as hunting equipment, will help keep you properly nourished.
Store food for later. Tundra nights are very long, so the amount of time you have for hunting and gathering is pretty short. Use the snow to freeze food, such as meat from animals you hunt, for later.
