Summary

The conservation status of most coastal species (13 species) under the EU Habitats Directive in Finland is not at an adequate level. A little over one-third of the conservation status assessments were favorable during the most recent reporting period. Between the first and second reporting periods, the conservation status of two species improved from unfavorable to favorable, but no similar improvement has occurred since then. Due to this and the small number of species, the slight improving trend of the indicator is not statistically significant.

Status: Very bad
Direction: Stable

Status

The status of the indicator is very poor. This status is determined based on the most recent reporting, relative to the goal that all assessments of coastal species listed in the Habitats Directive should be at a favorable conservation status. Only five out of the 13 assessments included in the indicator (approximately 40 percent) were judged to have a favorable conservation status (see Information About the Site and Indicator Calculation). An equivalent number of cases were assessed as inadequate, and around 20 percent were assessed as poor.

Trend

There is no clear statistically significant trend in the proportion of favorable conservation status assessments between different reporting periods in the indicator. However, the proportion of conservation statuses assessed as poor has systematically decreased between reporting periods, and the assessments for two species, the large copper (Lycaena dispar) and Erebia medusa subsp. polaris, have shifted from unfavorable to favorable conservation status after the first reporting period. In the first reporting period, one less species was assessed compared to the others, as the conservation status of the narrow-mouthed whorl snail (Vertigo angustior) was only able to be evaluated starting from the second reporting period.

Significance

The indicator includes 13 species from different biological groups (mammals, butterflies, mollusks, and vascular plants). These species are primarily rare and/or have a limited distribution range. Many of the plants in this group, in particular, have specific habitat requirements.

The indicator reflects the trends in populations, distribution ranges, and habitat quality of species considered particularly significant for conservation. It provides insight into whether conservation efforts and the sustainable use of natural resources are sufficient to ensure the favorable conservation status of these species. A conservation status is considered favorable if the species is viable in its natural habitats and is expected to remain so in the long term. The goal of the EU Biodiversity Strategy is for at least 30 percent of species currently not in a favorable conservation status to achieve a favorable status by 2030.
