1. Drylands are Earth's largest terrestrial biome and support one-third of the global population. However, they are also highly vulnerable to land degradation. Despite widespread demand for dryland restoration and rehabilitation, little information is available to help land managers effectively re-establish native perennial vegetation across drylands.
The ecological literature offers many conflicting recommendations for how managers should respond to ecosystem change and novelty. We propose a framework in which forest managers may achieve desired forest characteristics by combining strategies for (1) restoring historical conditions, (2) maintaining current conditions, and (3) transitioning toward novel conditions. Drawing on policy studies and the ecological and social sciences, we synthesize research on factors that shape forest management responses to ecosystem novelty and change. Although the ecological literature often suggests the likelihood of transitions to novelty, we found that a management focus on restoration and persistence strategies was supported by landowners, private and public lands policy, and forest manager capacity and culture. In this era of unprecedented change, managers and policy makers must address ecosystem novelty to achieve desired forest futures without eroding support for forest conservation and management.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
