29.04.2020 | HEPIA/HESSO | News WSL Swiss chestnut forests contain a genetic diversity that is unique in Europe, indicates a new study. Many chestnut forests consist of grafted trees.
The aim of this project is to determine the effect of climate change on the spread and incidence of chestnut blight in the southern Alps of Switzerland.
The WSL initiated together with other institutions a research program aiming at high quality chestnut timber *(Castanea sativa)* by minimizing the costs and improving the functional features and the stability of the coppice stands.
synthesis of palynological and archeological data shows the how the Romans helped to spread the chestnut and walnut culture in Europe.
15.11.2021 | Gottardo Pestalozzi | News WSL Could chestnut, being a southern species, thrive in a warmer climate north of the Alps? Yes and no, say our experts.
22.03.2021 | Université de Neuchâtel/WSL | News WSL A study of the entire genome of the chestnut blight pathogen helps to better understand how invasive organisms can spread.

Several viruses such as the prototype hypovirus CHV1, have previously been shown to reduce [...] host fungus. This property of viruses prompts many researchers to applied studies on biocontrol of chestnut blight as well as basic studies on both the fungus and its viruses. Despite the fact that C. parasitica

The main objective of this project is to make as complete an inventory as possible of all the giant chestnuts of the canton of Ticino and Misox, which have a circumference of more than 7 m.
