Global and European regional assessment: Least Concern (LC)
EU 27 regional assessment: Least Concern (LC)

Campanula serrata is endemic to the Carpathians, found in Poland, Slovakia, Ukraine and Romania. It has been described as common in parts of Ukraine and Poland. In Slovakia, there are a few hundred localities and the subpopulations are stable. Declines have been noted in parts of its range due to abandonment of pastoral systems and overgrowth of the habitat by woody plants and herbaceous species, forestation, fertilisers, overgrazing, and recreational activities. It is listed as Vulnerable in Poland but not included in any other red lists. There is no information for Romania available. Many of its localities are protected in Slovakia and Poland. The species is therefore classed as Least Concern.

Campanula serrata is endemic to the Carpathians and it is found in Poland, Slovakia, Ukraine and Romania.

In Slovakia it inhabits the central mountain ranges of the Western Carpathians and the Bukovské vrchy Mts (Mereďa and Hodálová 2011). In Poland it is found at elevations between 675-1,950 m asl and it occurs mainly in the subalpine belt. It is known from three regions: the Beskid Żywiecki mountains and the Tatra Mts (Western Carpathians) as well as the Bieszczady mountains (Eastern Carpathians) (Mirek and Piękoś-Mirkowa 2008). In Ukraine, it is a common species in the Chivcziny mountan massif and found more rarely in the Chornogora and Marmoroshki Alpy mountain massives (Ukrainian Carpathians).

In Slovakia, there are a few hundred localities and the populations are stable (Mereďa and Hodálová 2011). It is known from three regions of Poland: the Beskid Żywiecki mountains and the Tatra Mts (Western Carpathians) – a dozen localities as well as the Bieszczady mountains (Eastern Carpathians) where it is rather common (Mirek and Piękoś-Mirkowa 2008). In Poland individual subpopulations comprise from a few flowering stems to several thousand. Subopulations in the Beskid Żywiecki mountains are in regression because of abandonment of traditional pastoral management of mountain meadows. The Tatra subpopulations are stable. The biggest subpopulations, consisting of thousands of generative individuals, were observed in the Bieszczady mountains.

In Ukrainian Carpathians it is distributed in forest, subalpine and alpine belts. It is grows in meadows on limestone slopes as a component of Calamogrostidetum villosae, Festucetum, Rhodoretum and Nardetum communities.

This plant grows in the following Habitats Directive listed habitats (Commission of the European Communities 2009):

• 4060 Alpine and Boreal heaths
• 6150 Siliceous alpine and boreal grasslands
• 6230 Species-rich Nardus grasslands, on silicious substrates in mountain areas (and submountain areas in Continental Europe)
• 6430 Hydrophilous tall herb fringe communities of plains and of the montane to alpine levels
• 6520 Mountain hay meadows

Overgrowth of the habitat by woody plants and herbaceous species, forestation, fertilizing, and overgrazing are the main threats in Slovakia (Mereďa and Hodálová 2011). In Poland, the main threats for this species are modification of cultivation practices and abandonment of pastoral systems, paths, tracks, and cycling tracks, skiing complexes and outdoor sports and leisure activities.

Campanula serrata is listed as priority species on Annex II of the Habitats Directive.

The species occurs in 17 protected areas in Slovakia, comprising 49% of its national distribution (Mereďa and Hodálová 2011). In Poland it is listed as Vulnerable in the Polish Red Data Book (Każmierczakowa and Żarzycki 2001) and in the Red Data Book of the Polish Carpathians (Mirek and Piękoś-Mirkowa 2008). Most of the localities are protected in the national parks (Tatra and Bieszczady national parks) and in nature reserves. The species is also strictly protected at a national level (Piękoś-Mirkowa and Mirek 2006).
