Forum on the Flora and Vegetation of El Hierro (update will follow soon)

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 (
We intend to advert to 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



The map of Bory de St. Vicent 1803


Aeonium valverdense in the very south of El Hierro

Idiotaxonomy, genetics, phylogeny etc. (alphabetic order of the genera):
New taxa or changes in the denomination/specification in comparison to the Hierro-Checklist are highlighted.
