Abstract

In this paper a comprehensive list of Icelandic ferns (Polypodiopsida sensu PPG I) is presented alongside detailed distribution maps (5×5 km grid). Apart from general characteristics of the local range, details on ecology and conservation status are provided, including most common habitat types for each species, altitudinal range and a local red list status assessment according to IUCN criteria. The most important bibliography records for each species are also listed.

Highlights

With a total area of 103,100 km2, Iceland is the second largest island in Europe
The northernmost land belonging to Iceland is a small islet, skerry – Kolbeinsey (67,12 ̊N), while the southernmost point (63,29 ̊N) is on Surtsey, a newborn island, part of the Vestmannaeyar archipelago, which rose from the sea in 1963
Point distribution data were obtained from the database of Icelandic Institute of Natural History and aggregated to 5 km grid used in vascular plant mapping in Iceland (Wasowicz, 2020b)

Summary

Introduction

With a total area of 103,100 km2, Iceland is the second largest island in Europe. It lies in the Northern Atlantic Ocean with its northernmost parts touching the Arctic Circle. First records of ferns from Iceland date back to 1770, when the first list of plant species was published (König and Mueller 1770). A very common species present across the country and preferring dry habitats such as heath, grassland and birch forest. This rare species has been recorded only from three sites in Iceland: two in the Western Fjords, and one in the eastern part of the country.
