THE GREAT BUSTARD: PAST, PRESENT AND FUTURE OF A GLOBALLY THREATENED SPECIES


ABSTRACT

Great Bustards are still vulnerable to agricultural intensification, power line collision, and other human-induced landscape changes. Their world population is estimated to be between 44,000 and 57,000 individuals, showing a stable demographic trend at present in the Iberian peninsula, its main stronghold, but uncertain trends in Russia and China, and alarming declines in Iran and Morocco, where it will go extinct if urgent protection measures are not taken immediately. Our knowledge of the behaviour and ecolo­gy of this species has increased considerably over the last three decades, allowing us to control the major threats and secure its conservation in an appropriately managed cereal farmland. This species became ‘The Bird of the Year’ in Hungary in 2014.

EUROPEAN RED LIST OF BIRDS




EXECUTIVE SUMMARY

Aim

The European Red List is a review of the conservation status of all European species (mammals, birds, reptiles, amphibians, freshwater fishes, butterflies, dragonflies, bees, medicinal plants and selected groups of beetles, molluscs, and vascular plants) according to IUCN regional Red Listing guidelines. It identifies those species that are threatened with extinction at the regional level – in order that appropriate conservation action can be taken to improve their status. This Red List publication summarises the results for European birds.

Scope

The geographical scope is continent-wide, extending from Greenland in the northwest to the Urals in the northeast, and from the Canary Islands in the southwest to Cyprus and the Caucasus in the southeast. Red List assessments were carried out at two regional levels: for geographical Europe as described above, and for the 272 countries that were Member States of the European Union during the period covered by the 2008-2012 round of reporting under Article 12 of the Birds Directive.

Status assessment

The status of all species was assessed using the IUCN Red List Categories and Criteria (Version 3.1; IUCN 2012a3), which are the world’s most widely accepted system for measuring extinction risk. All assessments followed the latest Guidelines for Using the IUCN Red List Categories and Criteria (IUCN 20144) and the latest Guidelines for Application of IUCN Red List Criteria at Regional and National Levels (Version 4.0; IUCN 2012b5). Assessments are available on the European Red List website and data portal: http://ec.europa.eu/environment/nature/conservation/species/redlist, http://www.iucnredlist.org/europe and www.birdlife.org/datazone.

Results

At the European regional level, 13% of bird species are threatened, with 2% Critically Endangered, 3% Endangered, and 7% Vulnerable. A further 6% are Near Threatened. Within the EU 27, 18% of bird species are threatened, with 2% Critically Endangered, 4% Endangered, and 12% Vulnerable, and a further 6% are Near Threatened. The countries with the largest numbers of bird species are Russia and Turkey. Russia and Eastern Europe, and the Mediterranean, Black Sea and Caucasus regions show a higher species richness than northwest Europe. Russia and Turkey have the highest richness of threatened species. Important numbers of threatened species can also be found in the Caucasus region, the Iberian Peninsula and France, as well as in some regions in the Baltic States and Eastern Europe. Threatened species, mainly marine birds, are found in north and northwest Europe. There are 91 bird species endemic or near-endemic to Europe, found mainly in temperate and central Europe. The Mediterranean and Macaronesian islands have many endemic bird species, as does the Caucasus region. ‘Biological resource use’, and ‘agriculture and aquaculture’ are Europe’s top threats to bird species, followed by ‘climate change and severe weather’, ‘pollution’, ‘invasive and other problematic species, genes and diseases’ and ‘natural system modifications’.

Conclusions

Across Europe, many governments, NGOs and other parties are showing increasing commitment to conserving wild birds and their habitats and thanks to these efforts some species are showing signs of recovery. However, the proportion of threatened species in this assessment is comparable to that in the previous assessment a decade ago. Bird species continue to decline as a result of various threats, including illegal hunting, changing agricultural practices, invasive and alien species and habitat loss and degradation. It is evident that much more needs to be done to save threatened European bird species from extinction and to safeguard the bird populations of Europe.

PRELIMINARY METHODOLOGY TO ASSESS THE NATIONAL AND REGIONAL IMPACT OF U.S. WIND ENERGY DEVELOPMENT ON BIRDS AND BATS



Abstract 

The U.S. Geological Survey has developed a methodol­ogy to assess the impacts of wind energy development on wildlife; it is a probabilistic, quantitative assessment method­ology that can communicate to decision makers and the public the magnitude of these effects on species populations. The methodology is currently applicable to birds and bats, focuses primarily on the effects of collisions, and can be applied to any species that breeds in, migrates through, or otherwise uses any part of the United States. The methodology is intended to assess species at the national scale and is fundamentally dif­ferent from existing methods focusing on impacts at individual facilities. 

Publicly available fatality information, population estimates, species range maps, turbine location data, biologi­cal characteristics, and generic population models are used to generate both a ranked list of species based on relative risk as well as quantitative measures of the magnitude of the effect on species’ population trend and size. Three metrics are combined to determine direct and indirect relative risk to populations. A generic population model is used to estimate the expected change in population trend and includes additive mortality from collisions with wind turbines. Lastly, the methodology uses observed fatalities and an estimate of potential biological removal to assess the risk of a decline in population size. Data for six bird species have been processed through the entire methodology as a test case, and the results are presented in this report. 
  
Components of the methodology are based on simpli­fying assumptions and require information that, for many species, may be sparse or unreliable. These assumptions are presented in the report and should be carefully considered when using output from the methodology. In addition, this methodology can be used to recommend species for more intensive demographic modeling or highlight those species that may not require any additional protection because effects of wind energy development on their populations are projected to be small.

CARTA PISCÍCOLA ESPAÑOLA (CPE)

http://www.cartapiscicola.es/#/home


ACERCA DE
 
Los peces de agua dulce son entre los vertebrados los más amenazados. Esto es particularmente serio en la península ibérica, donde este grupo incluye un alto número de especies endémicas y amenazadas. A pesar del gran número de investigaciones y estudios técnicos hechos en esta área, estos datos están dispersos y por tanto no son disponibles para el uso público, para la gestión o la investigación 
 
La Sociedad Ibérica de Ictiología desarrolló la Carta Piscícola Española (CPE), con el objetivo principal de poner a disposición toda la información de los peces dulceacuícolas españoles. Para alcanzar este objetivo hemos reunido toda la información encontrada en los centros de investigación y administraciones públicas, y los hemos hecho disponibles en línea, creando una plataforma web sobre los peces dulceacuícolas para el uso del público en general. 

Esta base de datos integra información sobre la biología y ecología de los peces de agua dulce españoles, y sus referencias asociadas. Además, bajo el epígrafe “localidades”, se puede consultar los peces que habitan un río concreto, y consultar su abundancia relativa en esa comunidad, basada en la información publicada. Nótese que las áreas sin ningún dato de distribución de especies representan falta de información, y no ausencia de especies. En el campo de las “referencias” se puede acceder al listado bibliográfico completo.

La importancia de este proyecto incluye la necesidad de tener información precisa de la distribución de las especies que ayude a los gestores a desarrollar planes de supervisión y control y estrategias de conservación. Aún más, la información histórica sobre la distribución de las especies permitirá el análisis de las poblaciones piscícolas y contribuirá en el estado de conservación del grupo. El proyecto también proveerá datos para el Inventario Nacional Español del Patrimonio Natural y la Biodiversidad.

La base de datos de los peces dulceacuícolas españoles se deberá citar como:
