Since the adoption of the Habitats Directive in 1992 and the creation of the Natura 2000 network, the cumulative area of the network has steadily increased in EU Member States. In 2019, the network covered an area of 1 358 125 km 2 , encompassing nine biogeographical regions.
The coverage of terrestrial Natura 2000 areas was 784 994 km 2 in 2019, which is 18 % of the EU’s land area. This is more than the global biodiversity target for protected areas, which aims to conserve at least 17 % of terrestrial and inland water areas by 2020 (Aichi Target 11).
Long-term monitoring schemes show significant downward trends in common farmland birds and in grassland butterfly population numbers, with no signs of recovery.
Between 1990 and 2017, there was an 8 % decline in the index of 168 common bird species in the 25 EU Member States with bird population monitoring schemes and the United Kingdom (UK). The common forest bird index showed no decrease over the same period. The decreases were slightly greater if figures for Norway and Switzerland are included: 11 % for all common birds and 2 % for forest birds.
The decline in common farmland bird numbers between 1990 and 2017 was much more pronounced, at 33 % (EU Member States and UK) and 35 % (if Norway and Switzerland are included).
The index of grassland butterflies has declined strongly in the 15 EU countries where butterfly monitoring schemes exist. In 2017, the index was 39 % below its 1990 value.
The total ecological footprint of the EU-27 Member States plus the United Kingdom is high and is now more than twice the biocapacity available in the region (i.e. the capacity of ecosystems to produce useful biological materials and to act as sinks of carbon emissions). The picture is similar for the EEA-39 countries.
The region’s high ecological footprint means that its total demand for ecological goods and services exceeds that which Europe’s ecosystems can supply. This results in a large ecological deficit, which has negative consequences for the environment within and outside Europe.
Vegetation productivity indicates the spatial distribution and change of the vegetation cover - a key characteristic of ecosystem condition.
Vegetation productivity in Europe on average has a regional pattern of increase and decline. Increase was observed most in South Eastern Europe, over croplands and wetlands in the Steppic region and grasslands and sparsely vegetated lands and in the Black Sea and Anatolian regions. Decline happened most over croplands and grasslands in the Atlantic region as well as over wetlands in the Alpine region.
Climate has important influence on vegetation productivity in Europe. Strongest driver is precipitation, especially in the South Eastern regions. Decreasing number of frost days increased productivity in the Pannonian region but decreased productivity in the Atlantic region.
Climatic variations are important drivers of vegetation productivity, but land use changes are even stronger. Productivity was most increased by agricultural land management and converting other lands to agriculture, whereas largest decrease was caused by sprawling urban areas.
Recognition and understanding of the term 'biodiversity' has increased in the European Union. 71 % of interviewed EU citizens have heard of biodiversity and over 41 % of these know what it means.
At least eight out of ten Europeans consider the various effects of biodiversity loss to be serious for humans and for nature and agree that it is important to halt its loss. The biggest perceived threats to biodiversity are pollution of air, soil and water, man-made disasters and climate change.
Just under a third of respondents are aware of the Natura 2000 network, including 19 % who say they have heard about it but do not know what it is. However, the overwhelming majority agree that nature protection areas are very important in protecting endangered animals and plants or safeguarding nature's role in providing food, clean air and water.
Most Europeans are not willing to trade damage or destruction of protected areas for economic development.
Despite a reduction in the last decade (land take was over 1000km2/year between 2000-2006), land take in EU28 still amounted to 539km2/year between 2012-2018.
The net land take concept combines land take with land return to non-artificial land categories (re-cultivation). While some land was re-cultivated in the EU-28 in the period 2000-2018, 11 times more land was taken.
Between 2000 and 2018, 78 % of land take in the EU-28 affected agricultural areas, i.e. arable lands and pastures, and mosaic farmlands.
From 2000 to 2018, land take consumed 0.6 % of all arable lands and permanent crops, 0.5 % of all pastures and mosaic farmlands, and 0.3 % of all grasslands into urban areas.
In proportion to their area, Cyprus, the Netherlands and Albania saw the largest amount of land take between 2000 and 2018.
The re-cultivation of land increased from 2012 to 2018, led by Luxembourg, the Netherlands, the United Kingdom and Belgium.
The main drivers of land take during 2000-2018 were industrial and commercial land use as well as extension of residential areas and construction sites.
Since 1949, 1 039 non-indigenous species have been introduced into European seas.
The largest proportion of NIS introductions into European seas are associated with the shipping (49.1%) and corridor pathway (33 %: Suez Canal, inland canals). These are followed by unintentional movement of live organisms as contaminants (11 %) and escapees from aquaria, aquaculture and mariculture (5.1 %). Intentional releases in nature account for 1.7 % of NIS.
Main vectors for transfer of NIS by vessels are ballast waters (346 species) and boat hull fouling (287).
Shipping is the major pathway for introductions in all regional seas. Specifically, 45% of NIS introductions into Eastern Mediterranean and 82% in the Black Sea are associated with the shipping pathway.
Corridors are the main pathway in the Eastern Mediterranean, where more than 46 % of NIS was introduced via the Suez Canal. 14.5 % of NIC was introduced via inland canals in the Baltic Sea.
Transport contaminants (directly related to oyster aquaculture) are responsible for more than 30 % of introductions in the North-East Atlantic (Celtic, Iberian, Icelandic and North Seas).
While NIS introductions still occur, the rate of NIS introductions decreases in the time period 2006-2017 in all regional seas. The decreasing trend can be assigned to polices effectiveness as well as to other reasons, such as decreasing pool of potential NIS species, variations in sampling effort or available expertise.
In some of EU Member States, the number of new marine species introduced via human activity has already been reduced to zero.
Monitoring is not considered to sufficiently cover all the hot spot areas for new introductions. Identification of the areas that are most at risk of becoming invaded, as early detection mechanism will increase chances of eradication of invasive species.
Available data show that around 1 223 non-indigenous species (NIS) are present in the Europe’s seas, of which almost 81% (1 039) were recorded in the period 1949-2017. The species in question consist mostly of invertebrates (approx. 63 %).
The number of NIS is highest in the Mediterranean Sea, where almost 69 % (838) of all NIS have been recorded. A total of 21% (256) were recorded in the North-East Atlantic Ocean, 5 % (66) in the Baltic Sea and 3 % (32) in the Black Sea.
Mean numbers of new NIS recorded in the period of 2006-2011 (calculated for 6 yearly periods) were 28 species per year. The rate of new NIS recording slowed down to 16 species per year during the 2012-2017 period.
More than 80 of NIS species were identified as 'invasive alien species' (IAS) with a high potential to negative impact biodiversity and cause economic and social consequences.
The burnt area in the Mediterranean region has shown a slightly decreasing trend since 1980, but with high interannual variability; the meteorological fire hazard has increased over the same period as a result of global climate change. These opposite trends suggest that efforts to improve fire management have generally been successful.
Large forest fires in recent years have affected various regions in northern and western Europe in which fires were not prevalent in the past. More European countries suffered from large forest fires in 2018 than ever before, and Sweden experienced the worst fire season in reporting history. The unprecedented forest fires in several European countries in 2017 and 2018 coincided with record droughts and heatwaves in these years.
More severe fire weather and, as a consequence, substantial expansion of the fire-prone area and longer fire seasons are projected in most regions of Europe, in particular for high emissions scenarios. The increase in fire danger is projected to be particularly large in western-central Europe, but the absolute fire danger remains highest in southern Europe. Adaptation measures, such as improved fire prevention and suppression, can substantially reduce fire risks.
Concentrations of eight hazardous substances in European seas were generally 'low' or 'moderate' in line with the results of the previous assessment (2015). In some cases, however, the way we have traditionally defined 'moderate' levels meant that EU environmental quality standards (EQS) were exceeded. Any concentrations of hazardous substances exceeding EQS are unacceptable for marine organisms.
In general, concentrations in European Seas were 'moderate' for cadmium, mercury, lead, hexachlorobenzene, DDT (dichlorodiphenyltrichloroethane), polychlorinated biphenyls and benzo[a]pyrene. Both 'moderate' and 'high' concentrations of mercury exceeded the EQS and were found in a significant proportion of all seas. 'High' concentrations for hexachlorobenzene and benzo[a]pyrene, exceeding the EQS particularly in the case of the latter, were also found across all seas. Concentrations of lindane (gamma-hexachlorocyclohexane) were 'high' in the Mediterranean sea and generally low elsewhere.
Polychlorinated biphenyl levels appear to be decreasing in the North-East Atlantic Ocean. This suggests that policy measures and initiatives to decrease inputs of these substances in the region have had some success. For the remaining seven hazardous substances, it appears that the impact of abatement policies in this region might have stabilised.
Abatement policies for all eight hazardous substances have been in effect for the Baltic Sea, but no downward trends could be identified in the current assessment, indicating that the impact of such policies might have stabilised.
Because of insufficient data coverage, a comprehensive assessment all eight hazardous substances for the Mediterranean Sea could not be conducted. Available data for this region indicates that policies to reduce pollution have had an impact 'though.
The Black Sea is not included in this assessment due to lack of data.
Although further improvements are still necessary, the analysis of long time series shows clear and important signs of improvement in the North-East Atlantic Ocean and Baltic Sea ( 62.5 - 87.5 % of stocks meet at least one of the good environmental status criteria in these regions). Since the early 2000s, better management of fish and shellfish stocks has contributed to a clear decrease in fishing pressure in these two regional seas, with average fishing mortality dropping below the maximum rate of fishing mortality in 2017. This has led to signs of recovery in the reproductive capacity of several fish and shellfish stocks. If these efforts continue, fishing mortality in the region should remain on average near the maximum rate of fishing mortality and reproductive capacity should continue to improve, accomplishing the 2020 objective for healthy fish and shellfish stocks in the North-East Atlantic Ocean and Baltic Sea.
In contrast, the situation remains critical in the Mediterranean and Black Seas. Only 2 out of 33 stocks (6 %) in the Mediterranean Sea and 1 out of 7 stocks (14.3 %) in the Black Sea meet at least one of the good environmental status criteria. This is mainly due to the prevalence of overfishing and a significant lack of knowledge of the status of fish and shellfish stocks. Given this scenario, i t is unlikely that the 2020 policy objective will be met in the Mediterranean or Black Sea.
Overall, the 2020 objective of having healthy fish and shellfish populations is unlikely to be met in Europe’s seas without further collective action.
At the EU level, there has been a decrease in the agricultural nitrogen balance between 2000 and 2015, which is an indication of an improving trend. The main decrease was between 2000 and 2010; between 2010 and 2015 there was no further significant decrease.
A country comparison of the average agricultural nitrogen balance for the years 2000-2003 and 2012-2015, shows that for the majority of European countries there was a reduction in the nitrogen balance, reflecting an improving trend.
Although the agricultural nitrogen balance is decreasing in most Member States, it is still considered to be unacceptably high in some parts of Europe because of associated impacts on the environment. This is particularly true in western Europe and in some Mediterranean countries. Even in countries with low national averages, there can be regions with high nitrogen loadings because of agricultural intensity, such as livestock density. Further efforts are therefore needed to reduce the balance.
The total area of nationally designated protected areas in Europe [1] has increased over time and amounted to 1.5 million km 2 across 39 European countries in 2017, covering almost 26 % of terrestrial territory and inland waters. With more than 100 000 sites, though often small and fragmented, Europe has more protected areas than any other region in the world.
The coverage of ecosystem classes under the EU 'Mapping and Assessment of Ecosystems and their Services' (MAES) framework was affected by change processes between 2006 and 2012, with urbanisation the most dominant process. Urban ecosystems showed the highest net increase both in the EU-28 and in the EEA-39 countries, predominantly at the expense of cropland and grassland.
A very slight increase in coverage was observed in forest and woodland, while agricultural ecosystems, both cropland and grassland, continued to decrease.
Vulnerable ecosystems such as heathland and sparsely vegetated land (dunes, beaches, sand plains, bare rocks and glaciers) continued to disappear between 2006 and 2012, although the loss of wetlands seems to have levelled off for the first time over the same period. It should be borne in mind, however, that approximately two thirds of European wetlands were lost before the 1990s and their area has subsequently continued to decrease.
The ratio of forest fellings to increment is relatively stable and remains under 80 % for most countries across Europe. This utilisation rate has allowed Europe's forest stock to continue to increase.
The average growing stock density in European forests is 163 m 3 per hectare. While this varies considerably between countries, high individual values can be mainly put down to ecological conditions that favour tree growth, the protection of forest areas and, locally, forest harvesting difficulties.
Range shifts in forest tree species due to climate change have been observed towards higher altitudes and latitudes. These changes considerably affect the forest structure and the functioning of forest ecosystems and their services.
Future climate change and increasing CO2 concentrations are expected to affect site suitability, productivity, species composition and biodiversity. In general, forest growth is projected to increase in northern Europe and to decrease in southern Europe, but with substantial regional variation. Cold-adapted coniferous tree species are projected to lose large fractions of their ranges to more drought-adapted broadleaf species.
The projected changes will have an impact on the goods and services that forests provide. For example, the value of forest land in Europe is projected to decrease between 14 and 50 % during the 21st century.
The timing of seasonal events has changed across Europe. A general trend towards earlier spring phenological stages (spring advancement) has been shown in many plant and animal species, mainly due to changes in climate conditions.
As a consequence of climate-induced changes in plant phenology, the pollen season starts on average 10 days earlier than it did and is longer than it was in the 1960s.
The life cycles of many animal groups have advanced in recent decades, with events occurring earlier in the year, including frogs spawning, birds nesting and the arrival of migrant birds and butterflies. This advancement is attributed primarily to a warming climate.
The breeding season of many thermophilic insects (such as butterflies, dragonflies and bark beetles) has been lengthening, allowing, in principle, more generations to be produced per year.
The observed trends are expected to continue into the future. However, simple extrapolations of current phenological trends may be misleading because the observed relationship between temperature and phenological events may change in the future.
Observed climate change is having significant impacts on the distribution of European flora and fauna, with distribution changes of several hundred kilometres projected over the 21st century. These impacts include northwards and uphill range shifts, as well as local and regional extinctions of species.
The migration of many species is lagging behind the changes in climate owing to intrinsic limitations, habitat use and fragmentation, and other obstacles, suggesting that they are unable to keep pace with the speed of climate change. Observed and modelled differences between actual and required migration rates may lead to a progressive decline in European biodiversity.
Climate change is likely to exacerbate the problem of invasive species in Europe. As climatic conditions change, some locations may become more favourable to previously harmless alien species, which then become invasive and have negative impacts on their new environments.
Climate change is affecting the interaction of species that depend on each other for food or other reasons. It can disrupt established interactions but also generate novel ones.
Progress towards the 2020 target of improving the conservation status of habitats covered by the EU Habitats Directive has not been substantial since 2010. This indicates that significant conservation efforts need to be implemented to revert current trends.
At the EU level, only 16 % of the assessments of habitats protected under the Habitats Directive have a favourable conservation status.
Bogs, mires and fens have the highest proportion of unfavourable assessments, followed closely by grasslands.
Conservation status trends are quite variable across biogeographic regions, however, more habitats are stable than decreasing in the terrestrial regions. There are still significant gaps in knowledge on marine habitat types.
At the EU Member State level, the majority of assessments indicate a low number of habitats with a favourable conservation status.
The 2020 target of improving the conservation status of species covered by the Habitats Directive seems to have been met. This apparent progress, however, is largely attributable to improved data and changes in methodology.
Similarly, there has been little progress towards the target for bird populations under the Birds Directive. This indicates that significant conservation efforts need to be implemented to revert current trends.
At the EU level, 23 % of the assessments of species protected under the Habitats Directive indicate a favourable conservation status. At the same time, 60 % of species assessments are unfavourable. There are still significant gaps in knowledge, especially for marine species.
Fish, molluscs and amphibians have a particularly high proportion of species that exhibit a deteriorating trend.
The conservation status of species varies considerably from one biogeographic region to another. At Member State level, more unfavourable assessments are showing a decline than those that are improving.
In the EU, over half of the bird species listed in the Birds Directive are considered to be ‘secure’, i.e. they show no foreseeable risk of extinction, decline or depletion. On the other hand, 17 % of the species listed are still threatened and another 15 % are declining or depleted.
