Dataset: Global oyster reef restoration and recovery

This data set has been put together to incude data on oyster reef restoration, particularly to investigate how diversity and species abundance recover post restoration. 
THe data is affiliated to the following study: 
 Hemraj, D.A., Bishop, M.J., Hancock, B., Minuti, J.J., Thurstan, R.H., Zu Ermgassen, P.S. and Russell, B.D., 2022. Global success in oyster reef restoration despite ongoing recovery debt. bioRxiv. 

Abstract:
Habitat destruction and biodiversity loss from exploitation of ecosystems have led to increased restoration and conservation efforts worldwide. Disturbed ecosystems accumulate a recovery debt – the accumulated loss of ecosystem services - and quantifying this debt presents a valuable tool to develop better ecosystem restoration practices. Here, we quantified the ongoing recovery debt following structural restoration of oyster habitats, one of the most degraded marine ecosystems worldwide. We found that whilst restoration initiates a rapid increase in biodiversity and abundance of 2- to 5-fold relative to unrestored habitat, recovery rate decreases substantially within a few years post-restoration and accumulated global recovery debt persists at >35% per annum. Therefore, while efficient restoration methods will produce enhanced recovery success and minimise recovery debt, potential future coastal development should be weighed up against not just the instantaneous damage to ecosystem functions and services but also the potential for generational loss of services and long-term recovery.

摘要：

生态系统因过度利用而导致的栖息地破坏和生物多样性丧失，促使全球范围内加强生态系统的修复与保护工作。受干扰的生态系统积累了恢复债务——即生态系统服务累积损失——量化这一债务是开发更佳生态系统修复实践的有价值工具。在此，我们量化了牡蛎栖息地结构修复后的持续恢复债务，牡蛎栖息地是全球最退化的海洋生态系统之一。我们发现，尽管修复措施启动了生物多样性和丰度的快速增加，相对于未修复的栖息地，增加了2至5倍，但修复后的几年内，恢复速率显著下降，累积的全球恢复债务持续保持在每年>35%。因此，虽然高效的修复方法将产生增强的恢复成功率并最小化恢复债务，但未来沿海地区的发展应权衡的不仅仅是生态系统功能和服务的即时损害，还应考虑到服务代际损失和长期恢复的可能性。
