Pourquoi c'est important. Feux de forêt : 2022, année tristement record en Europe

Pourquoi c'est important. Feux de forêt : 2022, année tristement record en Europe | Biodiversité | Scoop.it
Plus de 785 000 hectares sont partis en fumée en 2022, le double de 2021. Ces feux de forêt ont généré les émissions de 9 mégatonnes de CO2.

Where are Europe’s last primary forests? - Sabatini - Diversity and Distributions - Wiley Online Library

Primary forests have high conservation value but are rare in Europe due to historic land use. Yet many primary forest patches remain unmapped, and it is unclear to what extent they are effectively protected. Our aim was to (1) compile the most comprehensive European‐scale map of currently known primary forests, (2) analyse the spatial determinants characterizing their location and (3) locate areas where so far unmapped primary forests likely occur.

Déjà plus de forêts européennes brûlées en 2022 qu’en 2021

Déjà plus de forêts européennes brûlées en 2022 qu’en 2021 | Biodiversité | Scoop.it

«C ’est pire que prévu », s’alarme le Système européen d’information sur les feux de forêt (EFFIS). Depuis le début de l’année 2022, soit depuis moins de huit mois, 517 881 hectares — plus de 5 000 kilomètres carrés — ont déjà été ravagés par les flammes en Europe — l’équivalent du département de la Mayenne. C’est déjà davantage que les 470 359 hectares (4 700 kilomètres carrés) brûlés pendant l’ensemble de l’année 2021. Si la tendance se poursuit, 2022 pourrait ainsi égaler ou dépasser 2017, année la plus catastrophique (...)

Where are Europe’s last primary forests ? Diversity and Distributions

Where are Europe’s last primary forests ? Diversity and Distributions | Biodiversité | Scoop.it

Researchers from the Geography Department of Humboldt-Universität zu Berlin (HU) led the creation of the first map of Europe’s last wild forests, including more than 1.4 million hectares in 34 European countries. „It is not that these forests were never touched by man, this would be hard to believe in Europe”, explains Dr. Francesco Maria Sabatini, lead author of the study.

Pinus sylvestris - EUFORGEN European forest genetic resources programme

Pinus sylvestris - EUFORGEN European forest genetic resources programme | Biodiversité | Scoop.it
Scots pine (Pinus sylvestris) is a long-living, coniferous tree characterized by its orange trunk. Globally, it is the most widely distributed pine and is found throughout all of Eurasia. The genetic variety is immense and several different subspecies exist across its distribution.
