Forum on the Flora and Vegetation of El Hierro

For any additions, comments and criticism on the data published in the course of the project “Flora and Vegetation of El Hierro” please e-mail to

Dr. Christian Stierstorfer (christian.stierstorfer@gmx.de)
Dr. Markus von Gaisberg (markus.v.gaisberg@gmx.de)

We intend to publish new literature (beyond the publications of the project) and information related with the flora and vegetation of El Hierro below.

See also our publications for the ongoing data interpretation.

For new information on the flora and vegetation of the Canary Islands, have also a look, e.g., at the following journals:
Botanica Macaronesica
Rincones del Atlántico
Vieraea
