Establishing protected areas (PAs) is important for the conservation of species, but more data is needed on their effectiveness.
![Expenditure on preventing biological invasions is far below environmental damage costs](https://environment.ec.europa.eu/sites/default/files/styles/oe_theme_ratio_3_2_medium/public/2022-10/NA1398.jpg?itok=a915vsf3)
Invasive alien species are a major global problem causing substantial environmental and economic damage.
![Benefits of agri-environment wildflower areas vary according to the surrounding landscape](https://environment.ec.europa.eu/sites/default/files/styles/oe_theme_ratio_3_2_medium/public/2022-10/NA1402-shutterstock_2170190605.jpg?itok=r6sYmFpQ)
Sowing wildflower areas is a common agri-environment measure, however, its biodiversity impacts are disputed.
![Estimating environmental damage from key resources required for EU low-carbon transition](https://environment.ec.europa.eu/sites/default/files/styles/oe_theme_ratio_3_2_medium/public/2022-10/NA1406-shutterstock_1509657515.jpg?itok=SwY-MZ09)
Transition to a low-carbon economy will create additional demand for many raw materials, production of which will have a range of environmental impacts.
![Abandoned agriculture in the Valencia Region, Spain: a transition to woodland and scrubland over a 50-year period](https://environment.ec.europa.eu/sites/default/files/styles/oe_theme_ratio_3_2_medium/public/2022-10/NA1408-shutterstock_2055777953.jpg?itok=RRZMTu9r)
Abandonment of agricultural areas in Mediterranean Europe can exacerbate fire risk due to increases in natural vegetation.
Specialised public prosecutors from the United States and EU Member States will step up their cooperation to tackle major cross-border and intercontinental environmental crime.
![Semi-natural conditions promote ecological recovery of urban streams](https://environment.ec.europa.eu/sites/default/files/styles/oe_theme_ratio_3_2_medium/public/2022-09/NA1395_shutterstock_73449412.jpg?itok=SKXUhtXR)
Freshwater ecosystems in urban areas face a variety of pressures and are often significantly degraded.
![Temperature-driven changes in traits of European birds are also influenced by other factors](https://environment.ec.europa.eu/sites/default/files/styles/oe_theme_ratio_3_2_medium/public/2022-09/NA1403_shutterstock_1889051317.jpg?itok=YCn4hX2T)
Studies that observe physical and behavioural changes in wild species over periods of rising temperature rarely evaluate the role of climate change in relation to simultaneous changes of other environmental factors.
![Environmental status assessment of Mediterranean Sea finds notable differences between ecoregions](https://environment.ec.europa.eu/sites/default/files/styles/oe_theme_ratio_3_2_medium/public/2022-09/NA1405_shutterstock_1640978215.jpg?itok=seMgM5tD)
The EU aims to achieve ‘good’ environmental status in marine areas across all Member States. This study assesses protected and non-protected sites in the Mediterranean Sea according to key ecological indicators.
![Identifying future climate refugia in Mediterranean Europe](https://environment.ec.europa.eu/sites/default/files/styles/oe_theme_ratio_3_2_medium/public/2022-09/NA1387_shutterstock_1898671162.jpg?itok=3Jcux-Bq)
Climate refugia are areas that remain relatively buffered from the effects of climate change over time, enabling them to play a vital role in safeguarding biodiversity.
