FERN
FERN, the Forests and the European Union Resource Network, is an international
non-governmental organization created in 1995 to keep track of the
EU’s involvement in forests and to co-ordinate NGO activities at the European level. Through its work, FERN aims to increase the political and economic opportunities for people to create a more balanced society in which human rights are fully respected and environmental and social values are fully integrated.

Fern
This article is about the group of pteridophyte plants. For the environmental organisation, see
FERN (NGO). For the letter of the
Ogham alphabet, see
Fern (letter). A fern is any one of a group of about 20,000
species of
plants classified in the phylum or division Pteridophyta, also known as Filicophyta. The group is also referred to as polypodiophyta, or polypodiopsida when treated as a subdivision of
tracheophyta (vascular plants). The study of ferns is called pteridology, and one who studies ferns is called a pteridologist. The term "
pteridophyte" has traditionally been used to describe all seedless
vascular plants, making it synonymous with "ferns and
fern allies". This can be confusing since members of the fern phylum Pteridophyta are also sometimes referred to as pteridophytes.
