The surface thaws out a bit.
During summer, the ground in tundra thaws and becomes soggy and wet. The cycle of freezing and thawing, crushes plant roots. This, in addition to cold temperatures, high winds, and short growing season, limit plant heights.
The warm summer temperatures melt the upper soil and gravel layers, but the ground a meter below is permanently frozen.
because the ground is frozen
Very cold, frozen. Tundra is frozen ground.
The tundra is one of the most fragile biomes on the planet. The food chains are relatively sipmle and thus easily disrupted. Because conditons are so extreme, the land is easily damaged and slow to recover.

No, the Pacific Golden-Plover doesn't use camouflage. During the summer, its feathers change into a lighter color that blends in with a tundra-like ground. It does this because in the summer it nests on tundra ground.
during summer and spring
yes it can. Tundra is a name given to the permanently frozen ground in the north of Canada and Russia. Tundra NEVER thaws even in the summer.
it melts
The tundra swan only lives in the tundra during the summer months. It migrates in the spring. Tundra swans have heavy amounts of down that keep them warm in the chillier parts of the summer. They nest on the swampy ground near tundra lakes and still waters. It's prime feeding ground with some of the thickest populations of mosquitos and berries in the world. So they can easily reer their young. Once their young are older in the fall they migrate to warmer climates.
The Arctic Tundra growing season is about 50 or 60 days!
They migrate further north to colder regions
During summer season
Caribou live in the North Woods or Taiga during the Winter and migrate to the Tundra during the summer. They have their calves on the Tundra.
Because some of the snow from the winter melts, so the water soaks into the ground, making it marshy.:)
During the winter animals living on a tundra have a thick layer of fat gained during the summer, they are covered with thick insulating furs or feathers, they have adapted color changing fur (brown in summer, white in winter), they also have short/stocky arms and legs to keep them warmer(closer to the body). Some tundra animals use solar heating to keep warm.
