Method synopsis

Paired sampling of vegetation inside exclosures before and after controlled grazing events to quantify herbivore impacts on standing crop biomass.

Synthesized from method descriptions across 2 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Conditional Exploitation and Context-Dependent Fitness Consequences of Pollination Mutualisms (2018), http://hdl.handle.net/10150/628436. The protocol was originally introduced by Hydrologic and Biotic Effects of Grazing vs. Non-Grazing near Grand Junction, Colorado (1970), Journal of Range Management. Implementations in other papers (listed below) may differ.

1. Monitor grazing impacts
   Erected several exclosures early in growing season. Clipped half of three exclosures (each 1 m²) just prior to arrival of sheep, allowed sheep to graze both halves, then revisited after departure of sheep and clipped the previously uncut halves.
   Quantities: 3 exclosures, each 1 m²Duration: Monitored before and after 6 hours of sheep grazing on August 22, 1974Conditions: Sheep grazing occurred for less than 6 hours on August 22, 1974
   Equipment: exclosure fencing, clippers

Typical Equipment

• exclosure fencing
