Résumé du projet
This specific project is located very close to the ETH in Hönggerberg and is about the impact of oak trees on forest resilience. Oak species set the framework to our European broaleaved forest ecosystems, hosting up to 1000 animal and plant species. Oak trees significantly contribute to the long-term stability of our forests. In this area, native pedonculate oaks are less and less adapted to dry and contrasting weather caused by climate change. Hence, the Zurich ForestLab will experiment with 4 sub-mediterranean oak species to assess their impact on urban forest resilience. Why Sub-Mediterrenean ? For anticipation, because species are expected to naturally migrate from South to North in the upcoming decades. Saplings will be placed on forest stands already suffering from climate change (e.g., harvested areas after bark beetle attack). Natural regeneration species will spontaneously grow amongst the oak trees and create a resilient biodiversity island within the forest.

Contexte local

The ForestLab is a beloved spot for scientists but also for Zurich inhabitants. Using public transportation, this urban forest is only 25 min away from the city center. The public is welcome to participate to citizen science activities, around various topics : biodiveristy and ecosystem services, adaptation to climate change, forest management practices, society and forests, cross-cutting issues. The whole forest area is an open-air laboratory for the ETH University, and the land is owned by the City of Zurich and local foresters grouped in a cooperation called Waldlabor. Each plot of forest is both an experiment and a recreationnal area.

Impact
CLIMAT
Contributes to the mitigation of the greenhouse effect and influences precipitation patterns and the local microclimate.
BIODIVERSITÉ
Preservation of local biodiversity by providing suitable habitats and resources.
EAU ET SOLS
Influences the quality and integrity of the soil-water system, and the cycling of water and nutrients.
SOCIAL & ÉCONOMIQUE
Supports human well-being, by providing resources, income, education, and supporting recreation and heritage.
