Colonization of islands by plants is often hindered by the absence of the appropriate mycorrhiza in the soil
Fungi are necessary for plants to colonize new territory - life short science news

Fungi determine whether plants will colonize new territory or not, a new study shows. Fungi, known as mycorrhiza, supply plants with nutrients that they have taken up from the soil. Plants pass carbohydrates on to the fungi.

Colonization of islands by plants is often difficult, as the appropriate mycorrhiza are lacking in the soil. Plant introductions made by men often concern plants growing in soil, thus containing mycorrhiza, and are thus usually successful.

This study shows that it takes more than geology and climate for a plant to colonize new territory.
