The first types of plants likely to arrive in an area once a glacier retreats are lichens and mosses. These organisms are considered pioneer species and are well adapted to colonizing bare, rocky surfaces. They can survive in harsh conditions and help to create a more suitable environment for other plants by breaking down rock and contributing to soil formation. Following the establishment of lichens and mosses, other plant types, such as grasses and shrubs, may gradually appear over time.
