Wavering Waterbirds

Protected sites are assigned based on population statistics for vulnerable and endangered species. This new study using WeBS data shows that changes in population size can affect local abundance, and thus influence whether or not key targets are met for site protection.

Wind farms and biodiversity: a collision course?

The development of green energy is more important than ever. One of the most well-developed and cheaply available options is wind power, but there is evidence that wind farms can also have a negative impact on biodiversity.

British birds more likely to go extinct

The UK has lost seven species of breeding birds in the last 200 years. Conservation efforts to prevent this from happening to other species, both in the UK and around the world, are guided by species’ priorities lists, which are often informed by data on range, population size and the degree of decline or increase in numbers. This paper presents the first analysis of British birds using the IUCN Red List criteria.
Curlew - Paul Hillion

The decline of the Curlew

Wader populations are declining worldwide, and here in the UK we have seen dramatic declines of Curlew populations. This study by the BTO in cooperation with the RSPB looks at which threats are influencing our Curlew.

Waders in decline in Strathallan, Scotland

The breeding populations of many different wader species are in decline across the globe, and there is an urgent need for information on how such changes in land management, particularly within farmland, may affect breeding waders. This study by a long-term BTO volunteer explores wader decline in Strathallan, Scotland over a period of 25 years.
