资源简介:
Clip-harvest of herbaceous biomass occurs within randomly located clip-harvest strips in 20m x 20m plots or subplots. Up to 20 non-forested Distributed plots (containing 1 clip strip per plot) and up to 30 Tower plots (containing 1-4 clip strips per plot) are sampled at each site. Tower plots are sampled every year. Tower plots at ungrazed sites are sampled once per year if there is a single annual biomass peak, and twice at sites with two biomass peaks per year in order to capture both warm season and cool season production. At grazed sites, sampling in Tower plots occurs once every 4 or 8 weeks while livestock are present. Distributed plots are sampled once every 5 years. Instrumentation:
