Abstract

•
Rangeland resilience is influenced by a variety of ecosystem properties that fall into two broad categories, 1) abiotic and 2) biotic.
•
Although important to consider in land management planning, abiotic properties cannot be directly influenced with management. In contrast, biotic properties of the ecosystem can be readily influenced by management.
•
The formula for robust biotic resilience to wildfire and resistance to invasive annual grasses in the northern Great Basin sagebrush ecosystem is about maintaining and promoting perennial bunchgrasses.
•
The management system must be resilient if we hope to promote ecosystem resilience in an ever-changing risk, seedling recruitment, and recovery environment. A successful strategy for promoting ecosystem resilience will require securing a resilient management system, and a shift in paradigm from random acts of opportunistic restoration to a sustained, organized, process-based approach for promoting ecosystem resilience.

提高北部大盆地的恢复力

•牧场恢复力受到各种生态系统特性的影响，这些特性可分为两大类:1)非生物和2)生物。•尽管在土地管理规划中考虑非生物属性很重要，但管理不能直接影响非生物属性。相反，生态系统的生物特性很容易受到管理的影响。•在北部大盆地山艾草生态系统中，维持和促进多年生束草对野火的强大生物恢复力和对入侵的一年生草的抵抗力的公式是关于维持和促进多年生束草。•如果我们希望在不断变化的风险、幼苗招募和恢复环境中提高生态系统的恢复能力，那么管理系统必须具有弹性。促进生态系统复原力的成功战略将需要确保一个有复原力的管理系统，并将模式从随机的机会性恢复行为转变为促进生态系统复原力的持续、有组织、基于过程的方法。
