Unravel the changing contributions of abiotic vs. biotic drivers of exosystem gas exchange under weather extremes (EcoDrive), Lägeren

Abstract

Site: Lägeren (CH-LAE, canton Aargau, Switzerland) Managed mixed deciduous mountain forest located on the steep Lägeren mountain (NW of Zurich, Swiss Plateau). The forest is highly diverse, dominated by beech and fir. The site is part of the international CarboEurope IP network and the NABEL (Swiss air quality network) and a long-term forest ecosystem research site (LWF) of the WSL (Institut f. Wald Schnee & Landschaft).; Longitude (WGS 84): 8°21'51.8" E; Latitude (WGS 84): 47°28'42.0" N Altitude (m.a.s.l): 682; Land cover (IGBP land classification): Mixed Forest; Soil type: The main soil types are rendzic leptosols (or rendzinas) and haplic cambisols according to the World Reference Base of Soil Resources (IUSS Working Group WRB, 2007). The litter layer is thin, since leaf litter decomposes almost completely within one year.; Geology: The main bedrocks of the study site are limestone, marl and sandstone, with transition zones between marl and limestone (loamy debris) and marl mixed with sandstone (loam).
