lichens
The first form of vegetation to appear on bare rocks is typically lichens. Lichens are pioneer species that can tolerate harsh conditions and can grow on bare substrates. They play a crucial role in the process of soil formation by breaking down the rock and facilitating the establishment of other plants, such as mosses, which may follow as the environment becomes more hospitable.

Lichens are typically the first colonizers of bare rock surfaces. They can break down the rock through a process called weathering, contributing to soil formation. Over time, other plant species can establish and further contribute to the development of a more diverse ecosystem.
Lichens are the dominant organism at first.
Lichens and mosses are among the first forms of vegetation to colonize bare rocks due to their ability to withstand harsh conditions and break down the rock surface through their growth. These pioneer species pave the way for more complex plant species to establish themselves over time.

Pioneer species, such as lichens and mosses, are the first to colonize bare rock. Over time, these species break down the rock, creating soil for other plants to establish. This process eventually leads to the development of a diverse plant community in a process known as primary succession.

Bare Rock Desert, very little sand, mostly rock
Lichens are the first organisms to appear in primary succession because they are able to colonize bare rock surfaces and begin breaking it down into soil through their ability to produce acids that break down minerals. Lichens are also able to survive in harsh environmental conditions, making them well-suited to establish themselves as pioneer species in the initial stages of primary succession.
Most of the bare rock in Antarctica is found along the mountain ranges and exposed ridges, particularly in areas like the Transantarctic Mountains and the Antarctic Peninsula. These regions have rocky outcrops and nunataks that are not covered by ice or snow, allowing for the exposure of bare rock.
