Method	Robust	Intrusive	Cost	Throughput
Respiration chamber	Yes	Yes	High	Low
Short-term accumulation chamber	Yes	Yes, but easily managed with grazing animals	Low	High
Greenfeed monitors	?	Moderately, requires modified grazing pattern	High	Moderate
SF6	?	Yes for sampling, less so for grazing	High	Moderate
