Applying the ecosystem approach to forest biodiversity

Despite being high on the political agenda, biodiversity is still declining. A new analysis has focused on forest biodiversity in Finland, Russia and Peru and concluded that a global ecosystem approach can make a link between human and ecological systems but bottom-up initiatives are needed to effectively put the concept into action.

How will biodiversity loss compromise Earth's life support systems?

Scientists have evaluated two decades of research into declining biodiversity and concluded unequivocally that loss of species richness leads to a reduction in how well ecosystems function. The researchers evaluated the evidence for key biodiversity theories and predicted that scientific progress in the next five to ten years will provide the information we need to efficiently conserve certain ecological processes.

Top tips to improve urban bird diversity

Planting trees and maintaining a well-balanced mix of vegetation in urban 'green spaces' can enhance the species diversity of birds and compensate for the negative effect of building, according to new research. Scientists recommend that increasing tree cover rather than limiting new development is the most effective long-term strategy to improve bird diversity in cities.

Set-aside land improves farmland biodiversity in Hungary

Setting aside agricultural land remains an important method of promoting biodiversity in Central Europe, according to new Hungarian research. Results have indicated that, compared to winter cereal fields, set-aside land has greater plant and insect diversity. This supports the continuing use of set-aside policy in Central and Eastern Europe.

More rigorous studies needed to evaluate impact of invasive birds

Conservation researchers have warned against acting on the findings of a previous study that argued for the eradication of several invasive birds, including the Canada goose and sacred ibis, in Europe. They suggest the results are based on anecdotal rather than scientific evidence, and that detailed feasibility studies are needed before such management decisions are made.




ive

More than protected areas needed to stop biodiversity loss

One strategy to halt the loss of biodiversity has been to create protected areas in the sea and on land. However, a new study suggests that unless additional measures are taken, particularly those that tackle human population growth and the increased use of natural resources, even the development of new protected areas will be unable to reverse the trend of global biodiversity loss.

'Effective mesh density': a useful measure of landscape fragmentation

Transport infrastructure and urban sprawl are increasingly dividing up landscapes in Europe, threatening wildlife. A new report has quantified landscape fragmentation across 28 European countries. To prevent further negative environmental impacts, it recommends protecting unfragmented areas, monitoring fragmentation and applying fragmentation analysis in planning.

Protect biodiversity to safeguard ecosystem services

Most species in an ecosystem could help supply essential ecosystem services, according to a recent study. The researchers found that 84% of species in the grassland ecosystems they studied contributed towards at least one ecosystem service. Losing any of these species would therefore degrade the ecosystem services such an environment could provide.

Gardens benefit bees and biodiversity in agricultural landscapes

Gardens are good for biodiversity, according to a study of intensively managed farmland in Sweden. The study has found that abundance and species richness of pollinating bees is higher near domestic gardens, with the pollination of a native plant also greater at these sites. Domestic gardens play a role in complementing 'natural' habitats for pollinators in impoverished environments.




ive

Deer culls are not effective for forest protection

Hunting is not an effective tool for reducing damage caused by deer to managed forests in Europe, according to a recent assessment. Forests will be better protected through 'close-to-nature' management techniques, says the study, which evaluated the effects of different control mechanisms on deer populations and behaviour, including the influence of wild predators, such as wolves, and forest structures.




ive

Plant biodiversity boosts ecosystem services in drylands

Plant biodiversity is crucial to the functioning of natural ecosystems in drylands across the world, according to recent research. Preserving plant diversity will be particularly important for maintaining the quantity and quality of services provided by ecosystems found in drylands that are vulnerable to the adverse effects of climate change and desertification.

'Bundled' PES schemes to boost cost-effectiveness

A recent project has developed a method to spatially target payments to areas where multiple ecosystem services, combining biodiversity conservation with carbon and water services, are jointly provided, so as to enhance the cost-effectiveness of the PES scheme. The study focuses on Madagascar, but the method could be applied at the national or regional level in any country.




ive

Alternative conceptual framework for PES schemes on offer

An international group of researchers has proposed a new way of describing payments for environmental services (PES). The new definition supplies a framework, incorporating the social aspects of PES, which can be used by practitioners, such as governments, to design and implement a variety of PES schemes.




ive

Positive link between High Nature Value farmland and bird biodiversity

High Nature Value (HNV) farmland is agricultural land that supports biodiversity and can be identified by its environmentally sound farming practices. New research on bird biodiversity on French HNV farmland has concluded that conservation of HNV farmland is important as well as conserving areas that were previously HNV and have undergone recent agricultural intensification.

Invasive alien plants threaten Antarctic biodiversity

According to new research, several areas of the Antarctic are at considerable risk from the establishment of 'alien' plants accidentally carried by visitors to the region. The findings demonstrate that invasive species pose risks even in remote areas and that these risks are likely to increase as the climate changes.




ive

Cost-effective monitoring of Payments for Environmental Services (PES)

To encourage protection of the environment, payments for environmental services (PES) schemes offer direct incentives to individuals and communities to maintain or improve the provision of environmental services. A recent study suggests indicators to monitor PES must be chosen very carefully to help ensure that monitoring does not cost more than the payments themselves.




ive

Weeds important for restoring biodiversity in farmland environments

The way in which agricultural land is managed can cause environmental changes that affect biodiversity and the services provided by ecosystems. A new study suggests agri-environmental schemes that focus on restoring common weeds, such as thistles, buttercups and clover, could have wide-ranging benefits as these plants appear to help stabilise the supportive links between different species found in farmlands.




ive

Diverse ecosystems vulnerable in changing environmental conditions

Changing environmental conditions could put diverse ecosystems, such as rainforests and coral reefs, at greater risk of multiple extinctions. A new study suggests that, rather than protecting ecosystems from collapse, high levels of biodiversity may actually prove risky in a situation such as climate change ??? where an unpredictable environment can suddenly extinguish a population needed to support an ecosystem, leading to knock-on effects further up the food chain.




ive

Habitat mapping method could help restore biodiversity

A new method for mapping long-term changes in habitat over large areas and in fine detail has been developed, which could help inform conservation plans to restore biodiversity to previous states. In a UK case study, researchers have used it to demonstrate the dramatic effects of intensive agriculture and afforestation on rural habitats since the 1930s.

The qualities of an integrated biodiversity observation system

There is a recognised need for a more comprehensive system to observe, track and compare biodiversity across the world. Three years ago a global network was established to help reach this goal. It has identified the necessary characteristics for such an integrated system and possible ways in which integration can occur.

Reducing roadkill: driver awareness need improving

Wild animals are more likely to be hit by vehicles during times where roads have poorer surface conditions and during periods of low light, according to a study of moose in Sweden. The researchers emphasise that it is not possible to accurately predict hotspots for wildlife collisions using data on the movement of the animals alone, and suggest that efforts to reduce accidents should focus on driver awareness and road conditions.

Networked domestic gardens boost urban biodiversity

Urban development is changing the composition of the natural landscape. A recent study has highlighted the importance of connecting fragments of green space, such as gardens, with ecological corridors to improve biodiversity and help spiders and beetles disperse within the urban landscape.




ive

Street lighting affects insect biodiversity

Insect communities are permanently changed by the presence of street lighting, according to new research. The authors of the study found that predatory and scavenging insects such as ants and ground beetles were more common under streetlights at all times of day, suggesting that light pollution does not simply attract different types of animals at night.




ive

Lower diversity of soil organisms in new farmland

Converting grassland to arable land can reduce the diversity of nematodes, predatory mites, earthworms and enchytraeid worms in the soil, according to a study by Dutch researchers. However, they found that restoring arable land to grassland did not fully restore the diversity of these four groups during the course of the four-year study.




ive

Biodiversity loss threatens key ecosystem functions

A synthesis of 192 studies has provided a quantitative estimate of the impact of the loss of plant biodiversity on ecosystem primary production, showing that this impact could be as great as that of other major environmental changes, such as climate warming, rising ozone levels and ocean acidification. They examined the effects of biodiversity loss on primary plant production of biomass and decomposition of plant litter, both of which underpin the carbon cycle and provision of key ecosystem services.

How does intensive agriculture threaten farmland bird populations?

Intensive agriculture is widely recognised as a major cause of declining farmland bird populations. New research has identified which aspects of agricultural intensification are most damaging to farmland bird numbers, examining bird populations at seven farmland sites across Europe. The researchers found that simplified landscapes created by intensive agriculture reduced bird numbers at the sites.




ive

Intensive agriculture is changing migratory route for birds

New research suggests that many Ruffs are changing their migratory route when flying north to their breeding grounds in northern Europe and to Asia from Africa. This is because their food supply has been reduced by the effects of intensive agriculture in the Netherlands, where they commonly stop off, causing them to shift eastwards to stopping-off points in Eastern Europe instead.

Addressing the mismatches of scale in biodiversity conservation

Biodiversity experts working in governance and science have called for greater integration of policy sectors, geographical levels and academic disciplines, in a stakeholder workshop. This would help ensure policy decisions realistically reflect complex relationships between ecological and governance processes in order to meet future biodiversity targets.




ive

Balanced approach to restoring farmland biodiversity shares and separates land

It is possible to balance agricultural production with improved biodiversity on farmland, according to researchers. A new study suggests using a combination of land sharing techniques, which enhance biodiversity on existing farmland, with land separation techniques, which designate separate areas for conservation and farmland production.

'Soft' flood defences to protect riverside biodiversity

Riversides that are unprotected by flood defences are home to more diverse plant communities, according to a new study. According to the researchers of the study, 'soft' approaches to flood management, which work in harmony with natural processes, could help promote biodiversity in flood-prone regions.




ive

Invasive alien slug could spread further with climate change

A recent study sheds light on why some alien species are more likely to become invasive than others. The research in Switzerland found that the alien Spanish slug is better able to survive under changing environmental conditions than the native Black slug, thanks to its robust 'Jack-of-all-trades' nature.

'Alternative agriculture': key to preserving food security and biodiversity?

The goals of providing sufficient quantities of food to support the world's growing population, whilst simultaneously protecting its biodiversity, may seem incompatible. However, a recent review of the literature has highlighted how 'alternative' agricultural practices can offer a realistic solution to the problems of achieving both food security and biodiversity conservation.




ive

Choice of tree species and site can increase plant diversity in plantation forest

Careful choice of tree species and sites could transform plantations into refuges for woodland plant diversity, new research from Ireland suggests. Plantations of native species on or near historic woodland and those with adequate light levels below the tree canopy were found to support more plant species.




ive

Patches of flowers boost pollinator diversity and lead to higher crop yields

Falling levels of insect pollination are causing declining yields of important agricultural crops. However, new research from South Africa now indicates that planting small patches of native flowers in agricultural fields can be a profitable and sustainable method of increasing pollination and yield.

A new method for evaluating threats to soil biodiversity

Little is known about the organisms that live within soil, although they play a vital role in the biological processes that support life on Earth. In a recent study, researchers calculated the relative risk of pressures caused by human activity on soil biodiversity in the EU, showing that intensive land use has the greatest impact.

Conserving the genetic diversity of Europe's forests

Conserving genetic diversity is vital to allow populations to adapt in the face of changing conditions. A new study, assessing the conservation of genetic diversity of trees across Europe, has identified areas for improvement that could help maintain the genetic diversity of Europe's forests.




ive

Risk-averse behaviour may improve farmland biodiversity

'Bet-hedging' behaviour among farmers, who diversify land use to avoid investing in a single land use that might fail, can boost farmland biodiversity, a new study suggests. However, because historical data show this is not the most frequent strategy used by farmers, balancing environmental and economic concerns in agriculture may still require public policy instruments, such as subsidies or taxes.




ive

Biodiversity databases: language and location help explain biases

Richer countries have more resources for gathering biodiversity information, creating a biased view of the worlds' species and their distribution. However, a new study argues that there are other reasons why some countries are underrepresented in global biodiversity databases, with low numbers of English speakers, large distances from the database host and low security acting as key barriers to data collection.




ive

Old rural parks can provide important refuges for forest biodiversity

Woodlands in the grounds of old manor houses or castles can provide high quality habitat for numerous forest species, a recent study from Estonia concludes. The researchers found that, compared to nearby forests, old rural park woodlands appeared to be better at supporting biodiversity.




ive

Biodiversity may help to prevent malaria outbreaks

Biodiversity could play a key role in preventing future outbreaks of malaria in tropical forests, according to a new study. Results indicate that a greater number of mosquito species could increase competition for mosquitoes that spread malarial parasites, whilst more vertebrate species could increase the likelihood that malarial parasites end up in 'dead-end hosts' that are unable to transmit the disease any further.
