Assessing progress towards achieving conservation targets is required for all countries committed to the Convention on Biological Diversity. The Natura 2000 network is the largest protected area network in the world and was created to protect Europe's threatened species and habitats, often requiring active management. This study assesses the effectiveness of areas classified under the EU Birds Directive at protecting Western Europe's agro-steppes, the last remnants of suitable habitat for several endangered bird species. We quantify agro-steppe habitat change in the last 10 years using high-resolution aerial images of 21 Special Protection Areas and surrounding areas.

Le dossier est consacré ce trimestre à la valorisation des produits de la gestion : "Rien ne se perd, tout se transforme". Comment valoriser les végétaux, voire les animaux, qu'on exporte ? Il existe des solutions intéressantes qui permettent de contribuer au développement d'activités locales vertueuses.

Although the relationships between habitats and ecosystem services (ESs) have been acknowledged, investigating spatio-temporal change in these has received far less attention. This study assesses the influence of habitat changes on ES delivery across space and time, based on two time points some 60 years apart, 1946 and 2009. A 1946 aerial photo coverage of two catchments in Scotland was used to construct digital photo mosaics which were then visually interpreted and digitised to derive historic habitat maps.
