... Die houdt rekening met een combinatie van factoren, zoals het aantal vliegbewegingen, het type vliegbewegingen, de aanwezige aantallen, de aanwezigheid van zeldzame soorten … Een hogere risicoscore kan betekenen dat de kans op aanvliegingen voor bepaalde soorten op bepaalde momenten hoog is, maar kan ook wijzen op een verhoogde kans op aanvliegingen van zeldzame soorten, waarbij de aanvlieging een belangrijker effect op de natuurwaarden zou kunnen hebben. De 'overall risk score' is een theoretische score die geen rekening houdt met de aan-of afwezigheid van hoogspanningslijnen. (Bron: Derouaux et al. 2020) The risk map shows which areas in Belgium are less or more prone to make collision victims. The risk scores take into account a combination of factors, such as the number and the type of flight movements, the numbers of birds present, the presence of rare species, etc. ...

For a long time the extent of the problem of bird mortality because of powerlines collisions was underestimated for Belgian network operator Elia. This changed in 2012 as the collaboration between Elia, Natuurpunt and Natagora was started. During the process of compiling a Belgian risk atlas, the availability of data and how to integrate them into a model were important steps in the preparatory process. Elia’s willingness to implement the use of this risk atlas in its business operations was a crucial factor in making the Belgian airspace safer for flying birds. Even though a collaboration between nature organizations and major economic players (in this case the energy distribution sector) is not immediately obvious, this is clearly the necessary step forward to take. Even though a lot of work still needs to be done, the noble effort to cooperate in this project, already led to a reduced impact on the number of powerline victims in Belgium.

Synthesis: opportunities for Dalmatian pelican Spontaneous return of the Dalmatian pelican as a breeding bird is not realistic in the medium term, leaving reintroduction as the only realistic option if one wants to get the species back in the Low Countries on the short term; A possible reintroduction of this native species meets the main criteria of the Dutch national government and the IUCN; the main argument of the reintroduction is the symbol function; the Dalmatian pelican acts as a flagship species for fish-eating species in restored, largescale wetlands in our delta. Nature experience and tourism are expected to benefit from the return, as well as the willingness to be more ambitious in further restoring our wetlands and protecting the species from a global perspective. There are also opportunities and initiatives for the reintroduction of this species in neighboring countries; Risks during the project can probably be largely limited by good communication and a smart, animal-friendly and professional implementation of a possible reintroduction; accompanied by good monitoring of the Dalmatian pelicans after reintroduction. Preventing collisions with high-voltage power lines and wind turbines is an important point of attention; Uncertainties and follow-up research: it is recommended to conduct further research into fish availability in one or a few most suitable clusters and to perform a more in-depth analysis at site level (including necessary mitigating measures with regard to energy infrastructure, availability of quiet breeding and rest islands).

Bird diverter devices were developed to improve power line visibility for birds and reduce their risk of collision. However, differences in efficacy between types of devices, and in some cases conflicting results, place in question the ability of these devices to reduce collision risk to birds. Here, we investigated the efficacy of three types of flight diverters in reducing avian collision with power lines: yellow spiral, orange spiral, and flapper, additionally we used unmarked spans as a control. We recorded bird collisions and estimated removal rates of bird casualties by scavengers in three different 400 kV transmission lines comprising 133 spans in southern Spain. A total of 131 dead birds from 32 species were found. The power line and the type of marker significantly affected avian mortality. The flapper flight diverter was responsible for a 70.2% lower mean avian mortality rate (95% Confidence Interval: 50-90%), followed by the orange spiral (mean = 43.7%, CI = 15.8-71.6%) and the yellow spiral (mean = 40.4%, CI = 2.8-78%), compared to control spans. Flappers were the only marker that showed greatest reduction in relation to non-marked spans. The flapper flight diverter showed the highest reduction in mortality and the narrowest confidence interval when tested in different environmental conditions, and thus may serve as a better alternative to the more commonly used spiral flight diverters.

Many migratory species have experienced substantial declines that resulted from rapid and massive expansions of human structures and activities, habitat alterations and climate change. Migrants are also recognized as an integral component of biodiversity and provide a multitude of services and disservices that are relevant to human agriculture, economy and health. The plethora of recently published studies reflects the need for better fundamental knowledge on migrations and for better management of their ecological and human‐relevant effects. Yet, where are we in providing answers to fundamental questions and societal challenges? Engaging a broad network of researchers worldwide, we used a horizon‐scan approach to identify the most important challenges which need to be overcome in order to gain a fuller understanding of migration ecology, and which could be addressed using radar aeroecological and macroecological approaches. The top challenges include both long‐standing and novel topics, ranging from fundamental information on migration routes and phenology, orientation and navigation strategies, and the multitude of effects migrants may have on resident communities, to societal challenges, such as protecting or preventing migrant services and disservices, and the conservation of migrants in the face of environmental changes. We outline these challenges, identify the urgency of addressing them and the primary stakeholders – researchers, policy makers and practitioners, or funders of research.

Every year since 1990 the population trends of the most common breeding birds in Wallonia (81 species) have been estimated using a standardized sampling procedure. Several dozens of volunteers make one or more sets of 15 fixed spots where birds are counted for 5 minutes. Each year, the observers repeat the observation following the same methodology. From these data, an annual abundance index has been calculated for each species and population trends are estimated. Over the last 28 years, most common species are declining in Wallonia. Only 26 % of them have shown an increase in numbers. On average across all species, bird populations have declined at a rate of 1 % per year for the last 28 years. In the last 10 years the average rate of decline has accelerated. The rate of decline is greatest in farmland birds, especially in the ground-nesting species. The rate of decline has been greater in migratory species which cross the Sahara than in non-migratory species, and than in those species which migrate only a short distance. The factors mainly responsible for decline in bird populations in the countryside would seem to be changes in agricultural practices, together with the general intensification of agriculture, though other factors are also to be considered (evolution of the forest, high population density of ungulates and climate change).

High- and very-high-voltage power lines have been identified as a major human-induced source of mortality for birds. When birds fly in large groups, or in poor visibility conditions, they can collide with these structures, in some instances in sufficiently large numbers to raise concern. Several international agreements on nature conservation acknowledge this important issue. In answer to this concern, Elia, as the power transmission system operator in Belgium, intends to identify its own overhead power lines that present a serious collision risk for birds. The main objective of this project is to map collision-prone power lines in Belgium and to classify existing power lines according to their “dangerousness” in this regard. This report’s priority classification of power lines should ultimately be seen as an answer to the following question: “Given present-day knowledge of bird distribution and relative sensitivity to collision mortality, what are the most dangerous power-line sections, i.e. those where the mitigation of collision risk should be focused as a priority?” It is neither a substitute for a proper Environmental Impact Assessment nor a mitigation plan in itself. As a first step, a list of collision-sensitive bird species in Belgium was compiled on the basis of a review of the literature, casualty records and expert judgment. Not only “collision risk” itself was taken into account, but also the “conservation value” of each species and the probable population impact of additional mortality. In a second step, this list was used to define four coherent bird species groups of interest, in order to facilitate and organize the mapping work. These groups are the waterbirds (for which numerous data are available at site level), rare breeding birds (for which good data are also available in both Wallonia and Flanders), which migrate in large numbers (the mapping exercise was more difficult for them, because migration is to a considerable extent geographically spread across Belgium, with no clear migrant funnel) and widespread breeding bird species (for which relative density maps need to be built because they are not associated with specific sites or locations). In a third step, up-to-date knowledge of bird distribution in Belgium was used to create maps for each of the coherent bird species groups. Numerous sources of data were used: wintering waterbird counts, roost and colony counts, breeding bird atlases and observations from datarecording portals. Spatial modelling was applied to obtain high-resolution maps of widespread species and help define the best staging area for some other species. A “collision risk score” was defined for each of the geographical zones delimited on the maps, or based on the distance from important bird areas. The combination of the maps, with the aid of this scoring system, allows the classification of all power-line masts according to their associated collision risk for birds. Most of the more dangerous power lines are located in areas with major concentrations of waterbirds occur: the polders area, the wetlands in the vicinity of the Port of Antwerp and some river valleys (Yser, Meuse, Haine). About 3.4% of the network can be considered “high priority” for mitigation. A technical chapter describes the available mitigation tools. In the case of existing power lines, a cost-effective manner to decrease collision risk involves placing markers or “diverters” on the lines, in order to make them more visible to birds, even in poor visibility conditions. On the basis of current knowledge, it can be concluded that any large device (increasing the apparent size of the line to at least 20 cm), placed at least every 5-10 m along the line, preferably on the earth wire, is likely to significantly reduce collision risks. In view of the available budget, the placement of diverters can now be planned on Belgian power lines, focusing first on the high priority sections. Of course, other considerations, such as geographical “grouping” of diverters in order to reduce cost and opportunities provided by other planned work on specific power-line sections, may also influence the final planning, which is now in Elia’s hands.

We developed interpolated climate surfaces for global land areas (excluding Antarctica) at a spatial resolution of 30 arc s (often referred to as 1-km spatial resolution). The climate elements considered were monthly precipitation and mean, minimum, and maximum temperature. Input data were gathered from a variety of sources and, where possible, were restricted to records from the 1950-2000 period. We used the thin-plate smoothing spline algorithm implemented in the ANUSPLIN package for interpolation, using latitude, longitude, and elevation as independent variables. We quantified uncertainty arising from the input data and the interpolation by mapping weather station density, elevation bias in the weather stations, and elevation variation within grid cells and through data partitioning and cross validation. Elevation bias tended to be negative (stations lower than expected) at high latitudes but positive in the tropics. Uncertainty is highest in mountainous and in poorly sampled areas. Data partitioning showed high uncertainty of the surfaces on isolated islands, e.g. in the Pacific. Aggregating the elevation and climate data to 10 arc min resolution showed an enormous variation within grid cells, illustrating the value of high-resolution surfaces. A comparison with an existing data set at 10 arc min resolution showed overall agreement, but with significant variation in some regions. A comparison with two high-resolution data sets for the United States also identified areas with large local differences, particularly in mountainous areas. Compared to previous global climatologies, ours has the following advantages: the data are at a higher spatial resolution (400 times greater or more); more weather station records were used; improved elevation data were used; and more information about spatial patterns of uncertainty in the data is available. Owing to the overall low density of available climate stations, our surfaces do not capture of all variation that may occur at a resolution of 1 km, particularly of precipitation in mountainous areas. In future work, such variation might be captured through knowledge-based methods and inclusion of additional co-variates, particularly layers obtained through remote sensing.

The expansion of overhead power lines worldwide challenges companies of energy transmission and distribution, regulators and environmental consultants, among other stakeholders, to effectively mitigate their negative impacts on wildlife. Wire-marking is currently the most widespread and recommended measure to reduce bird collisions with these infrastructures. Nevertheless, and despite its importance for a bird-friendly development of energy projects, there is still much uncertainty about what explains wire-marking effectiveness. We performed an extensive literature review and meta-analysis to evaluate the overall effectiveness of wire-marking in reducing bird collisions with power lines, including the possible influencing factors of power line voltage, habitat and type of device. We gathered data from 35 field studies across the world (which included 66 trials) assessing the effectiveness of wire-marking based on regular carcass searches beneath power lines. Overall, wire-marking reduced bird collisions with power lines by half (50.4%; 95% Confidence Interval Estimate: 40.4–58.8%), although this estimate of effectiveness is lower than the one reported in a meta-analysis performed in 2011. Despite the effort to include both peer-reviewed and grey literature studies in the present meta-analysis, the risk of publication bias could not be entirely excluded and may be still overestimating the true overall effect of wire-marking. High heterogeneity among the study outcomes hindered the power to detect clear moderating effects, with none of explanatory variables being statistically significant. Large between-study heterogeneity is (to some extent) explained by the variety of anti-collision devices available, wire-marking intensities used and ecological circumstances in which the experiments were carried out. Nonetheless, it may be also related to within-study methodological biases and reporting gaps in the existing field studies. Robust experimental designs (ideally using Before-After-Control-Impact approaches), comprehensive reporting of results and broad dissemination of study findings are needed to increase the statistical power of future meta-analyses. Ways to achieve these improvements in field studies are presented in detail. Their inclusion in future meta-analyses will increase the knowledge on the drivers of wire-marking effectiveness, which is critical to better inform decision-making processes and environmental management plans.

Maps of species' distributions or habitat suitability are required for many aspects of environmental research, resource management and conservation planning. These include biodiversity assessment, reserve design, habitat management and restoration, species and habitat conservation plans and predicting the effects of environmental change on species and ecosystems. The proliferation of methods and uncertainty regarding their effectiveness can be daunting to researchers, resource managers and conservation planners alike. Franklin summarises the methods used in species distribution modeling (also called niche modeling) and presents a framework for spatial prediction of species distributions based on the attributes (space, time, scale) of the data and questions being asked. The framework links theoretical ecological models of species distributions to spatial data on species and environment, and statistical models used for spatial prediction. Providing practical guidelines to students, researchers and practitioners in a broad range of environmental sciences including ecology, geography, conservation biology, and natural resources management.

Today's intensive farming practices are known to have affected farmland biodiversity negatively in many different ways. As far as birds are concerned, they are known to have suffered during both summer and winter. Relatively little is known about the effects on birds during migration. We studied the stopover ecology of the Eurasian golden plover Pluvialis apricaria, a species listed in EU Birds Directive, in intensively farmed arable land in southernmost Sweden in the autumns of 2003–2007. We used key ecological variables (length of stay, fat deposition and moult) as fitness proxies to evaluate how the birds manage in this habitat. Eurasian golden plovers were present in large numbers mainly on arable fields from early August to November and radio-tagged birds were found to stay in the area for up to three months. Adult birds carried out a substantial part of their flight feather moult during their stay. Body mass increased only somewhat during moult, but from the last stages of moult and onwards fuel loads corresponding to 24% above lean body mass (LBM) were accumulated at a rate of 0.5% of LBM per day, before the birds departed. Juveniles arrived later, from mid Sep., and had a similar pattern of fuel deposition. The fact that the birds choose to stay for long periods, moult in the area, and manage to store substantial fuel loads strongly suggests that Eurasian golden plovers do well in this intensively farmed arable land.
