État de la populationTexte officiel évaluation IUCNExpert

Across its range, this species occurs in isolated subpopulations which has led to extensive genetic diversity across populations. Although population size has not been quantified it is not believed to approach the thresholds for it to be considered threatened. It is considered common in some habitats. As the species grows in wet habitats, and this habitat is declining due to human impact, the species may be declining in some areas.

Description complète des menacesTexte détaillé évaluation IUCNExpert

Subpopulations are scattered which has resulted in high genetic variation between subpopulations and high specificity to local conditions. If habitat loss occurs, this will result in a narrowing of the gene pool and replanting efforts may be challenged by limited ability to survive outside of specific conditions. Adaptation to specific local conditions could also present a threat in future as climate change alters water regimes. This does not present a significant threat at the moment, but could present a greater threat in the future.

A recently evolved fungus, Phytophthora alni, has killed 10% of trees in south England and Wales, and may have a wider impact in the future (Webber 2004).

Mesures de conservation recommandéesStratégies de conservation IUCNExpert

Due to the genetic differentiation between subpopulations, it is important to protect the existing diversity of natural subpopulations. This species is listed as Least Concern in the National Red Lists of Denmark (NERI 2005), Estonia (eBiodiversity Estonia 2012), Norway (Artsdatabanken 2010), Luxembourg (Colling 2005), Sweden, Switzerland (Moser et al. 2002) and Great Britain (Cheffings and Farrell 2005). There are over 100 known ex situ collections found in botanic gardens and arboreta world wide (BGCI 2015).
