Sparse Trees

Sparse Trees

The Sparse Trees anthrome is one of the more literal names because these regions are simply scattered groupings of trees interspersed with bare ground and low growing ground cover. 

This anthrome is made up mostly of the tundra in the far northern reaches of the world, but does include the edges of deserts and smaller less contiguous regions where little vegetation can grow.  Ground covering is primarily lichen, mosses, and small shrubby and herbaceous plants.  The median temperature sits below the freezing point and no human life is sustained .
