A mighty beech tree. Shelter. Shade.
And more than meets the eye.
Its trunk populated by lichen and moss, habitat for invertebrates, food for insects and birds…
Roots in symbiosis with microorganisms.
Detritus feeders and bacteria converting leaf litter into compost.
Chemical signals exchanged.
Climate regulating photosynthesis and evapotranspiration.
..a (not so) simple example of a whole ecosystem and ecosystem services.
