摘要

•在牧场规模上提供多种生态系统服务的放牧管理需要平衡预期结果。•大量的挑战包括将土壤和相关植物群落特征的空间异质性与降水的时间变异性相匹配。•规定性放牧(整个季节的连续和时间控制的轮牧)消除了人类适应不断变化的条件的经验知识，而适应性多围场(AMP)放牧通常需要高密度的牲畜，这减少了牲畜的体重增加。•短草草原放牧管理的“混合搭配”或混合两种方法可以降低干旱风险，增加受关注的草原鸟类繁殖栖息地的可用性，并维持牲畜生产。

Balancing ecosystem service outcomes at the ranch-scale in shortgrass steppe: The role of grazing management

•
Grazing management for providing multiple ecosystem services at the ranch scale requires balancing desired outcomes.
•
Abundant challenges involve matching the spatial heterogeneity in soils and associated plant community characteristics with the temporal variability in precipitation.
•
Prescriptive grazing (season-long continuous and time-controlled rotational grazing) removes the human experiential knowledge to adapt to changing conditions, whereas adaptive multipaddock (AMP) grazing often invokes high stock densities, which reduce livestock weight gain.
•
A “mix-and-match” or blending of both approaches for grazing management in the shortgrass steppe can result in reduced drought risk, enhanced breeding habitat availability for grassland bird species of concern, and sustained livestock production.
