Tundra
El bioma Tundra reúne 51 ecorregiones en el catálogo mundial de Plotwright. Paisajes polares y de alta montaña sin árboles, formados por arbustos bajos, juncias, musgos y líquenes, donde el frío y una temporada de crecimiento corta limitan la altura de las plantas. Los suelos suelen estar congelados como permafrost, y estos sistemas se recuperan solo muy lentamente tras una perturbación.
