Hooked on moss
This type of moss is also called Hooked Scorpion moss because its leaves are usually swept over to one side. There are other hooked mosses in the Arctic, but botanists recognize this one because it is dark in colour and has characteristic plump shoots.
Moss in charge
Scorpion moss can grow into very large patches. This mass of moss causes organic matter to build in and around Arctic ponds and lakes, providing substrates that support a transition to other, more complex, plant community types.
A moist environment
Unlike some arctic mosses, Scorpion moss requires a wet habitat to grow. If the ponds and lakes in which it is found were to dry up, this species of moss would not survive for long. After as little as a week of being dried out, it may not revive.
