AoR 2: Karen Launchbaugh, Grazing Management Fundamentals by Art of Range published on 2018-09-21T18:58:06Z Guest Karen Launchbaugh and host Tip Hudson discuss grazing management principles that apply everywhere, coordinating grazing management across multiple ownerships, stocking rate planning for long-term rangeland health, and the pros and cons of common grazing rules of thumb.

Your helpful document on this topic, Shane, is consistent with these definitions. You define harvest efficiency (HE) as: "The total percent of vegetation harvested by a machine or ingested by a grazing animal compared to the total amount of vegetation grown in the area in a given year…. Harvest efficiency is the percentage of forage actually ingested by the animals from the total amount of forage produced.” Again, harvest coefficient is the calculated allowable use factor, harvest efficiency is the actual results on the ground. I would still argue that utilization rate is more applicable to a single grazing event, whereas HE intends to communicate the percent of annual biomass removed. 2018-10-31T22:39:23Z Comment by Art of Range The harvest coefficient is understood as the “percent allowable use” (Holechek 1988). It is a mathematical variable chosen by the manager to calculate how much of a total year’s forage/biomass production should be considered available to grazing animals in stocking rate. According to Holechek (2000), “the harvest coefficient is the percentage of total forage produced that is assigned to grazing animals for consumption.” 2018-10-31T22:38:42Z Comment by Shane A. Green You had an opportunity here and blew it. Your use of terminology is wrong and you have added to the confusion surrounding utilization and harvest efficiency. 2018-10-31T17:07:49Z
