Restoration ecology articles from across Nature Portfolio

International initiatives set ambitious targets for ecological restoration. Here, the authors conduct a meta-analysis to quantify the impacts of ecological restoration on greenhouse gas emissions and find that forest, grassland, and wetland restoration reduce global warming potential.

Restoration supports the recovery of ecological attributes such as cover, complexity, and diversity to slow the areal decline of natural ecosystems. Restoration activity is intensifying worldwide to combat persistent stressors that are driving global declines to the extent and resilience of coral reefs. However, restoration is disputed as a meaningful aid to reef ecological recovery, often as an expensive distraction to addressing the root causes of reef loss. We contend this dispute partly stems from inferences drawn from small-scale experimental restoration outcomes amplified by misconceptions around cost-based reasoning. Alongside aggressive emissions reductions, we advocate urgent investment in coral reef ecosystem restoration as part of the management toolbox to combat the destruction of reefs as we know them within decades.

Myriad structures, from purpose-built concrete modules to decommissioned petroleum platforms, have been deployed in US waters to create artificial reefs. Assessing their spatial coverage would help marine spatial planning but the task is challenging. Now a study does that and reveals some important ecological insights.
