Short summary
There is increasing interest in measuring methane emissions from tree stems in a wide range of ecosystems. This is commonly done with bulky closed chambers, which limit measurement to a very narrow range of tree stem sizes and shapes. We designed, described and tested new semi-rigid stem-flux chambers with decisive advantages (reduced permeability, fast deployment, adapted headspace volume, easy to carry in multiple sizes, extremely light and economical) ideal for use in remote ecosystems.
