This area is bare rock because it was originally attached to the mountain but over the years corrupted and finally fell off
Bare Rock
Additional infoSoil: non existentSpecies diversity: noneTrophic level: none Niches: noneNutrient recycle: minimal

Stage 1 Pioneer Species
At this stage lichen were being Carried through the air and landedOn these rock and they would start To break the rock down and the dead Lichen would have given nutrients for The future plants to grow
Soil: simple and very thinSpecies diversity: lichen onlyTrophic level: 1 producerNiches: very simpleNutrient recycle: minimal

Stage 2 Early ColonizersSoil: tiny bit deeper still not so rich Species diversity: fewTrophic levels: 2Niches: low getting higherNutrient recycle: little
In this stage plants are starting to grow through theCracks in the rock on the some what soil.

Stage 4 Mature Forest/ Climax Community
Trees and Plants take overThe trees and grasses are fully grown With all the different types there isAnd all the different types of animals Are fully moving in to the brand new Boreal forest.

Disturbance
Some body left a fire going The hole forest has caught on fire allBecause of one person. All the trees areBeing burnt to the ground and all the grassTo a crisp. All the plants are being burntTo a crisp all the animals are fleeing outOf the forest as fast as they can to try to Get to safe ground
