Europe’s rich array of biodiversity, habitats and species is under threat due to human activities and climate change. This degradation affects our well-being and economy. The EU is taking action to restore and protect the vital systems that support life on our planet.

Europe's nature under pressure

Europe’s biodiversity continues to decline at an alarming rate, with most protected species and habitats confronting poor conservation status. Much more effort is needed to reverse current trends and to ensure resilient and healthy nature.

The pressures on biodiversity may vary depending on the habitat, region or species. Our assessments show that many agricultural activities, intensifying land management practices, and the abandonment of extensive management are the most common overall pressures.

Urbanisation and leisure activities are the second largest pressure and it particularly affects habitats such as dunes and coastal and rocky habitats. Forestry activities are the main source of pressure on arthropods, mammals and non-vascular plants. The pollution of air, water and soil from agriculture in particular, affects most habitats, especially in the European Union’s Atlantic and continental regions.

What causes biodiversity loss in Europe?

Alt text: Infographic showing eight different sources of biodiversity loss in Europe. Long description: The infographic provides information on the sources of biodiversity loss in Europe. Eight causes, each represented by a circle containing a simple graphical representation of the cause, are themselves arranged in a circle in the center of the figure. The corresponding text for each cause is placed next to its corresponding graphical circle. From the top, and in a clockwise manner, the causes and their associated text are as follows: 1. The text reads, “Urbanization and leisure activities account for 13% of all reported pressures, representing 48% of all marine pressures.” The accompanying graphic depicts a pair of high-rises. 2. The text reads, “The modification on water regimes, physical alterations of water bodies, and removal of sediments predominantly affect freshwater habitats and fish.” The accompanying graphic depicts a flowing river. 3. The text reads, “13% of all pressures for birds stem from the exploitation of species, mainly relating to illegal killing and hunting. In Europe, the annual hunting bag amounts to at least 52 million birds.” The accompanying graphic depicts a hunter holding a rifle to his shoulder. 4 The text reads, “Almost 50% of all pressures related to pollution can be attributed to air, water, and soil pollution caused by agriculture.” The accompanying graphic depicts a heavy tractor in a barren field. 5. The text reads, “Climate change is reported as a rising threat, particularly due to ongoing changes in the temperature and the decrease of precipitation.” The accompanying graphic depicts two birds flying over the tops of the trees under a blazing sun. 6. The text reads, “Forestry activities represent 11% of all pressures, particularly affecting forest habitats and woodland species.” The accompanying graphic depicts a stack of cut lumber in a forest. 7. The text reads, “Invasive alien species, such as the false indigo bush, particularly affect dunes and sclerophyllous scrubs as well as species such as breeding seabirds.” The accompanying graphic depicts the leaves of the false indigo bush. 8. The text reads, “with 21%, agriculture is the most frequently reported pressure for habitats and species. Abandonment of grasslands and intensification is particularly impacting pollinator species, farmland birds, and semi-natural habitats.

How does pollution impact ecosystems?

One of the major drivers of biodiversity loss and decline in Europe and worldwide is pollution. Pollution puts pressure on freshwater, marine and terrestrial ecosystems, the functions they maintain and the services they provide.

The types of pollutants that affect ecosystems are wide-ranging — from human-made chemical products, nutrients (e.g. nitrogen) and microplastics to ambient sources such as noise and light.

One of the sections of our zero pollution monitoring assessment examines available knowledge and trends in pollution and associated impacts on ecosystems.
