Overview

Distribution

Range Description

Veronica repens is a strict endemic species from Corsica with Oro-West-Médeuropean origins. It is a common species in the central mountains of Corsica and a bit rarer in the other part of the island. Its extent of occurrence is less than 5,000 km² within which the area of occupancy is less than 500 km².

Range Description

This species is endemic to the Iberian Peninsula. It is found at an altitude of 1,300-3,000 m in mountains of two different distribution areas. The
Sierra Nevada (Granada) and Sierra de los Filabres (Almeria) are the southeastern nucleus, and Sierra Segundera (Zamora, Orense, Beira Alta - Portugal), Sierra de la Cabrera (León) and Sistema Central (Salamanca, Avila, Cáceres and Madrid, Guadalajara) are the northwestern and central nucleus where it is more disperse (Castroviejo et al. 2009).

Habitat and Ecology
The species is found in "pozzine", peat and grass around lakes, among dwarf shrubs, at spring borders and runnels, or lands from 780 m to 2,290 m of altitude with long snow periods. This Hemicryptophyte grows on granite (granodiorite and monzogranite) and granitic glacial sediments.

Justification
Veronica repens has a fairly restricted distribution, but it is a common species and it is found at more than 30 locations in Corsica. The populations do not seem to be threatened by the deterioration of their habitat. It is therefore listed as Least Concern.

Justification
More information on the number of sites, population trend, preferred habitats and ecology is needed for Veronica nevadensis. It is not clear how the potential threats are affecting the populations at present. For the moment it is assessed as Least Concern, but once more information has been received a new assessment is recommended in order to determine whether the species is threatened.

Threats

Major Threats
The habitat is submitted to the increase of trekking that includes more pedestrian passage on the pozzine and a higher risk of fires. Therefore, there are more guards from the natural parks around the different lakes.
In the future, due to the decrease of stockbreeding, this species will be affected by the competition of the woody plants.

Management

Conservation Actions

Conservation Actions
The species is currently not legally protected. It is included in the Red Data Book: v olume II. Surveillance of the existing sites is done by guards from the Regional Natural Park of Corsica and Botanical Conservatory from Corsica and search for new sites is underway.
It is recommended to follow-up the dynamics of different populations, to increase knowledge about the biology, resilience, and conservation needs of the species, and to collect seeds for ex situ conservation.

Conservation Actions

Conservation Actions
There are no specific measures in place or needed. Many of the populations are in the Sierra Nevada National Park and other protected areas.
It is assessed as Data Deficient in the Red List of Andalucia (Cabezudo et al. 2005).

More information on the number of sites, preferred habitats and ecology is needed as well as information on the population trend and how the potential threats are affecting the species.
