Biodiversity: Diversity of living nature.


Biodiversity Convention: "Biological diversity" means the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems.


The highest biodiversity within the project is found in the dry stony area:

Biodiversity

Dry meadows are areas of great biodiversity. 40% of plant species and 50% of animal species live in dry meadows. The soil must be poor for the insects and birds that nest there.

There is good diversity of lichens, growing on dry stones. 

Lichens:

Are endangered globally;

An algae and fungus symbiosis;

The algae takes care of photosynthesis and the fungus - the house.

Breathe: photosynthesizes during the day and exhales CO2 at night;

Can survive in the desert;

Important in Nordic countries as wildlife food source;

Is not a moss (green plant);

Competition between moss and lichen;

Sometimes enters into symbiosis with blue algae (cyanobacteria);

Are excellent bioindicators: accumulate heavy metals, pollutants, etc.


The lichen that grows on the stones is a crustacean lichen, it does not come off, it grows in the stone:
