[NB01] Population size of selected bird species

Neutral
11.07.2023

Population trends of selected bird species show that the state of the environment in the cultural landscape is still deteriorating, especially in some parts such as Prekmurje and Ljubljansko barje. The population of selected forest bird species is stable, however, a trend of deterioration of its habitat was recorded in recent years, as a result of intensified logging. Bird populations that winter on Slovenian rivers and other water bodies have different trends that are mostly in line with trends of regional biogeographic populations of waterbirds in Europe.

[NB02] Threatened species

Despite the country’s small surface area, species diversity in Slovenia is extremely high. The abundance among numerous plant and animal species is decreasing, with some species becoming endangered with the possibility of extinction. For example, more than four fifths of all known amphibians and reptiles in Slovenia, as well as almost half of all mammals (this represents 41 species) are on the Red List of Threatened Species.

[NB03] Game preservation

The state of wildlife in Slovenia is favourable; larger epidemics have not been identified. The number of herbivorous ungulates as well as wild boars has decreased. An increase in wildlife losses due to road kill raises concerns. The total amount of damage caused by wildlife has decreased.

Wildlife management includes all animal and plant species. Regulation of wildlife populations is based on game management plans that are submitted for adoption to the Ministry of Agriculture, Forestry and Food by the Slovenia Forest Service in accordance with a prescribed procedure.

[NB04] Subterranean biodiversity

Slovenia has some of the greatest subterranean biodiversity in the world. The aquatic fauna, with its 200 species, is by far the richest, while the terrestrial fauna, with 150 species, is second only to the more southern areas of the Dinaric karst. Five Slovenian cave systems have been listed among the 20 richest cave systems in the world. The Postojna-Planina Cave System, with its 50 aquatic and 35 terrestrial species is by far the most abundant. The Cave Protection Act protects the subterranean environment as a whole.

[NB05] Plants – species richness and endangered species

Neutral

Species diversity in Slovenia is stil considerably well preserved, distinctly higher in western part of the country. Without systematic monitoring on permanent plots it is impossible to recognize short term trends, but in some regions negative trends are result of landuse changes and impact of alien invasive species.

[NB06] Brown bear

30.03.2021

The population of brown bear in Slovenia is in a favorable state of preservation, with a trend of improvement. The estimated number of bears in spring was 990.

The population is the northwestern part of the Dinaric-Pind population, which was in 2012  estimated at 3950 individuals and is stable or growing.

[NB07] Compensation for damage caused by protected animal species

Bad
16.06.2021

Slovenian Environmental Agency (ARSO) is responsible for providing monetary compensation for damage caused by protected animal species. The amount of damages fluctuates depending on the available food in nature, according to spring cold or summer drought, there’s more damage expected. The year 2019 was like this, with 1.301 reported damage cases caused by protected animal species (76 % more than the year before), out of which, 1.173 received the compensation. A total of 570.580,39 EUR was paid in compensation, for damage caused by 28 different protected animal species.

[NB09] Plants – invasive species

Bad
18.03.2022

The share of present invasive species (eg. Robinia pseudacacia, Ailanthus altissima, Buddleja davidii, Erigeron annuus) in the last decade shows an increasing trend. An increase in the share of invasive species is evident along the great lowland rivers Sava, Mura and Drava, as well as along the Kolpa river. In higher areas of Slovenia, particularly in the Alps and the Dinaric region, invasive species are very few or entirely absent. However, a notable increase in their share along the western border of the Dinaric region raises concerns.

[NB10] Dolphins

23.07.2009

The population of bottlenose dolphins (Tursiops truncatus) in Slovenian territorial waters is part of a larger population living in the northern Adriatic Sea. The state of the Slovenian population is being monitored by the Morigenos  – the Slovenian Marine Mammal Society. Throughout the year, Slovenian waters regularly host 40–100 bottlenose dolphins. Despite considerable temporal variability in density and frequence of appearance in Slovenian waters, the population trend seems to be negative and the estimated number of animals has been slightly decreasing over the years.

[NB11] Species of European interest

Bad
29.04.2020

The conservation status of species in Slovenia indicates that only 30% of species have a favorable status. Furthermore, also the trends are unfavourable. In the years 2013-2018, the proportion of species with favorable conservation status remained stable according to the previous reporting period, while the proportion of species with poor conservation status has increased. As many as one third of Europe's important bird species have a negative or uncertain short-term trend.
