Près de la moitié des forêts suisses sont des forêts qui nous préservent des dangers naturels.
Pour en finir avec la pollution aux algues vertes, les chercheurs de l’Université de Mexico ont créé un système de phytoépuration placé en amont des cours alimentant les lacs. Inspiré des jardins flottants aztèques, il permet de débarrasser l’eau des excédents de nitrates et de phosphore.

"The purpose of this report is to study the profitability of forestry in Finland and in Russia by describing the methods used for profitability assessment and following up in both countries by using specific examples to calculate the profitability of forestry. Also, the availability of profitability assessment results is studied on a state-level. Finally, the methods and results are compared."

En forêt, l’approvisionnement des arbres en éléments nutritifs s’est dégradé. Les méthodes de récoltes d’arbres entiers aggraveraient encore ces pertes de nutriments, c’est pourquoi seul le bois fort devrait être exploité.

Le programme Forêts Anciennes à haute valeur de conservation du WWF, a pour objectif d’identifier et promouvoir le bon état de conservation des forêts remarquables, de par leur naturalité (notamment ancienneté et maturité) et leur biodiversité. Il se focalise notamment sur les forêts du bassin méditerranéen. Legs de l’histoire, les forêts anciennes sont aujourd’hui rares et souvent méconnues. Elles constituent pourtant un patrimoine extraordinaire, d’une haute valeur scientifique et écologique, mais également économique, sociale et culturelle. Connaître et faire connaître ces forêts anciennes, leurs valeurs, mieux les préserver, maintenir au mieux leurs qualités dans la gestion productive est un enjeu capital. Ces forêts sont également un élément clé de résilience de la biodiversité forestière face aux changements climatiques.

Les plantes à fleurs sont aujourd’hui dominantes dans tous les environnements, mais cela n’a pas toujours été le cas. De nouveaux résultats montrent que durant le Crétacé, les plantes à fleurs ont conquis l’Europe en trois phases s’étalant sur plus de 40 millions d’années.

Les scieries ont surtout besoin de bois de moins de 40 cm, mais les gros bois gardent tous leurs avantages. Dans cette perspective il serait erroné de vouloir raccourcir la durée des concepts de production.

"Forests play a key role in the global climate system. The Nordic countries have extensive forests with large and growing tree biomass that captures substantial amounts of the greenhouse gas carbon dioxide. Nordic forests are also important for biodiversity, with complex ecosystems providing habitats for about half of all known native species and threatened species in Finland, Norway, and Sweden. Forests also supply the basis for the economically important forest sector. In this report we review current knowledge on the role of old forests in the carbon cycle, their natural dynamics and importance for biodiversity."
