Short summary
Short summary
Our study investigates the conditions in temperature, precipitation, humidity, and soil moisture leading to the browning of the European forests in summer. Using a Random Forest model and satellite measurement of vegetation greenness, we identify key conditions that predict forest damage. We conclude that hot and dry conditions in spring and summer are adverse conditions, in particular for broad-leaved trees. The hydro-meteorological conditions during the preceding year can also have an impact.

Short summary
Short summary
CHclim25 is a high-resolution climatic dataset for Switzerland, offering daily, monthly, and yearly data on temperature, precipitation, sunshine duration, and other derived climatic variables for the baseline 1981–2010 period and future periods up to 2099. Downscaled to 25 m using local topography, it outperforms global datasets, especially at higher elevations. CHclim25 enhances both temporal and spatial resolution, opening avenues for ecological and environmental research in Switzerland.

Short summary
This paper assesses peoples' knowledge and perceptions of the invasive palm (Trachycarpus fortunei) in Ticino, Switzerland. Such information is important for guiding decision-making and management planning. In general, although the palm induces positive perceptions in most respondents, the majority of people realise the threat that invasions pose to the region. Therefore, most respondents supported the regulations and management for this popular ornamental plant.
This paper assesses peoples' knowledge and perceptions of the invasive palm (Trachycarpus...
