METHODS:

Soil carbon dioxide flux measured at multiple times during the growing seasons of 2012 and 2013, each from a surface area of 0.03178 m^2, using a manually-operated closed chamber survey system (Speckman et al. 2014) with accompanying soil moisture measurements at 5 cm depth (SM300 with HH2 Meter, Delta-T Devices, Cambridge, UK) and soil temperature (HH508 with Type E thermocouple penetration probe, Omega Engineering, Stamford, CT, USA) at 10 cm depth. Measurements were made at three plots in Betasso, five plots in Lower Gordon Gulch (seven in 2013), and three plots in Upper Gordon Gulch.
