Typical goals of wetland restoration efforts are to conserve, create, or enhance wetland structure, and to achieve wetland function that approaches or exceeds natural conditions. Measuring wetland establishment, condition, and resilience can be difficult, especially because monitoring wetland function has traditionally been time-intensive, costly, and often required repeat field-based surveys. Remote sensing provides novel collections of data and facilitates rapid assessments of wetland landscapes, land cover, species/habitat composition, change detection, degradation, diversity, as well as system threats and pressures. A combination of remotely collected and in situ vegetation data were used in conjunction with landscape metrics and vegetative indices. These data were used to evaluate and compare changes and trends in condition, function and resilience of restoration sites and reference wetlands in southwest Louisiana, USA. Results of this work show the restored wetlands reached structural and functional equivalency to reference wetlands after approximately three to ten years post-construction. With adequate maturity, the restored wetlands outperformed the reference wetlands, having higher percentage of land, land aggregation, aboveground vegetation productivity and floristic quality. Supplementing traditional field-based methods with remote sensing applications provided enhanced metrics for inventorying and monitoring of wetland resources, forecasting of resource condition and stability, and adaptive management strategies.

使用遥感和野外数据量化恢复的路易斯安那湿地的性能和复原力

湿地恢复工作的典型目标是保护,创造或增强湿地结构,并实现接近或超过自然条件的湿地功能。测量湿地的建立,状况和复原力可能很困难,尤其是因为传统上监视湿地功能耗时,费钱,并且经常需要基于野外的重复调查。遥感提供了新颖的数据收集,并促进了对湿地景观,土地覆盖,物种/栖息地组成,变化检测,退化,多样性以及系统威胁和压力的快速评估。结合了远程收集和就地植被数据以及景观指标和植物生长指数。这些数据用于评估和比较状况的变化和趋势,西南路易斯安那州恢复点和参考湿地的功能和复原力。这项工作的结果表明,在施工后大约三到十年后,恢复的湿地达到了与参考湿地相同的结构和功能。在足够成熟的情况下,恢复的湿地优于参考湿地,具有更高的土地比例,土地聚集,地上植被生产力和植物区系。用遥感应用补充传统的基于实地的方法,为湿地资源的清单和监测,资源状况和稳定性的预测以及自适应管理策略提供了增强的指标。这项工作的结果表明,在施工后大约三到十年后,恢复的湿地达到了与参考湿地相同的结构和功能。在足够成熟的情况下,恢复的湿地优于参考湿地,具有更高的土地比例,土地聚集,地上植被生产力和植物区系。用遥感应用补充传统的基于实地的方法,为湿地资源的清单和监测,资源状况和稳定性的预测以及自适应管理策略提供了增强的指标。这项工作的结果表明,在施工后大约三到十年后,恢复的湿地达到了与参考湿地相同的结构和功能。在足够成熟的情况下,恢复的湿地优于参考湿地,具有更高的土地比例,土地聚集,地上植被生产力和植物区系。用遥感应用补充传统的基于实地的方法,为湿地资源的清单和监测,资源状况和稳定性的预测以及自适应管理策略提供了增强的指标。地上植被生产力和植物区系。用遥感应用补充传统的基于实地的方法,为湿地资源的清单和监测,资源状况和稳定性的预测以及自适应管理策略提供了增强的指标。地上植被生产力和植物区系。用遥感应用补充传统的基于实地的方法,为湿地资源的清单和监测,资源状况和稳定性的预测以及自适应管理策略提供了增强的指标。
