lichens are called pioneer organisms because they are the first type of organisms that started to live in a certain forest or such. For example, If a volcanic island were to appear in the middle of the ocean. It is devoid of life at first. Certain organisms will land on the island either by washing up on the volcanic ash or land on it after being carried by the wind currents. One of these organisms would be a lichen. Lichens are considered pioneer because they will begin to destroy the rock and ash producing soil. They can survive because a lichen is a mutualistic relationship between a fungus and an algae. Once these lichens have done their work other organisms will appear, bacteria, algae, various grasses, etc. This is called ecological succession.
You are most likely to find pioneer species growing on bare, recently disturbed land, such as volcanically-formed islands, sand dunes, or areas affected by forest fires or glacial retreat. These species are the first to colonize and establish on such harsh environments, paving the way for other plant species to follow.
An early successional species is a species that thrives in disturbed or newly formed habitats. These species are typically fast-growing, adaptable, and pioneer species that can quickly establish themselves in these environments. They often create conditions that facilitate the growth of other species in the ecosystem.
a greater chance to survive if the environmental conditions suddenly change.

The most species are probably in the ocean.
newly erupted volcano is where u would find pioneer species
Pioneer species are the first species to colonize an area that was previously devoid of life, often after a disturbance such as a fire or volcanic eruption. These species are typically hardy and able to tolerate harsh conditions, paving the way for other plant and animal species to establish themselves in the ecosystem. Over time, pioneer species are gradually replaced by more diverse and complex species as the ecosystem matures.

A pioneer species is typically fast-growing, able to quickly colonize bare or disturbed habitats, and can thrive in harsh environmental conditions. These plants often have small seeds that are easily dispersed and have adaptations that help them establish quickly in new areas. They play a key role in initiating succession and creating conditions for other plant species to follow.

The most common Antarctic plant is lichen. There are about 150 different types of lichen able to survive the extreme temperatures, as well as 30 mosses, some fungi, one species of hair-grass and one liverwort.
You are most likely to observe primary succession in a terrestrial community on recently formed volcanic islands, sand dunes, or areas that have been cleared by glaciers or landslides. These areas lack soil and vegetation, so pioneer species must colonize the area first. Over time, as these pioneer species die and decompose, they begin to build up soil, allowing more complex plant species to establish and creating diverse communities.

The most popular lichen is the reindeer lichen (Cladonia rangiferina), which is commonly found in arctic and subarctic regions. It is an important food source for reindeer and other grazing animals.
