生态恢复的一个基本前提是它注重退化系统的恢复。虽然这显然是一个简单的目标，但实际上“退化”一词的定义、使用和评估方式存在很大差异。此外，关于什么是降级、什么不是降级的决策存在显着的主观成分，这通常与所考虑的价值观和目标有关。对于高度退化的系统可能没有什么争议，因为有价值的特性的损坏和损失是显而易见的。但是，如果系统变革不那么明显，并且这些变化有利有弊，那么决定系统是否退化并因此需要恢复就变得更加困难。面对持续的气候、土地利用和其他环境变化，系统不断发生变化，决定哪些系统已退化以及哪些系统与以前的系统仅有所不同变得更加困难。差异并不一定等于退化。稀缺管理资源的有效利用依赖于公开辩论和解决此类问题的能力的提高。
An underlying premise of ecological restoration is that it focuses on the recovery of degraded systems. While this is an apparently straightforward aim, there is in fact considerable variation in how the term “degraded” is defined, used and assessed. In addition, there is a notable subjective component to decisions regarding what is degraded and what isn't, and this often relates to the values and goals being considered. There is likely to be little argument over highly degraded systems where damage and loss of valued characteristics are evident. But where system change is less stark and the changes have mixed benefits and disbenefits, the decision on whether the system is degraded and hence in need of restoration becomes more difficult. As systems continue to change in the face of ongoing climate, land use and other environmental changes, decisions become more difficult regarding which systems are degraded and which are merely different from what was there before. Difference does not necessarily equate to degradation. Effective use of scarce management resources relies on an improved ability to openly debate and resolve such issues.
