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.
lichens are pioneer species because they grow where no other plant life grows, then when they die, they make the soil rich and so other plants can grow that fertilize the soil when they die. lichens start a chain reaction.
Newly formed volcano - exposed rock and no topsoil
Species most often associated with early succession of a forest include red squirrels, ground-nesting birds like killdeer, rodents and a few others. Species of plants include lichen, moss, shrubs, wild grasses and clovers
You most likely have a teddy bear hamster. I suggest googling hamster species and matching pictures of your species!
a greater chance to survive if the environmental conditions suddenly change.

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.

After a natural disaster has damaged a local ecosystem, there will likely be a period of recovery and restoration as the ecosystem tries to rebuild itself. This may involve changes in species composition, soil fertility, and overall ecosystem balance. Human intervention through restoration efforts may also be necessary to facilitate the recovery process.
In a tundra biome, succession typically starts with the colonization of lichens and mosses on bare rock or soil. These pioneer species help in breaking down the rock, eventually leading to the accumulation of organic material and soil formation. Over time, grasses, shrubs, and eventually trees might establish, changing the community composition and increasing biodiversity in the tundra biome.
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.
weeds
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.
