由于海平面上升(SLR)和土地利用变化，沿海植物群落正在改变或消失。与SLR一起，佛罗里达大沼泽地生态系统经历了大规模的排水和恢复，改变了整个佛罗里达州南部的沿海植被。为了了解沿海植物群落是如何随着时间的推移而变化的，需要精确的测绘技术，以足够精细的分辨率来定义植物群落，以检测细微尺度的变化。我们探索了使用双季节和单季节Worldview-2卫星数据来绘制三个红树林和四个邻近植物群落的地图，其中包括拥有联邦濒危植物Chromolaena Cruitata的梧桐木/糖藻群落。在区分所有感兴趣的群落方面，双季节数据比单季节数据更有效。结合光探测和测距(LiDAR)高程数据，利用双季节数据绘制了湿地国家公园(ENP)内海岸段的海岸植物群落图。总体地图准确率为86%。红树林和黑树林是研究区的优势群落，占研究区面积的50%。其余所有群落的≤覆盖度均为10%，包括梧桐木/葡萄糖类群落。ENP栖息着21种受到SLR威胁的稀有沿海物种。我们的地图提供的空间清晰、定量的数据为监测这些物种未来栖息地的变化提供了一个精细的基线。我们的结果也为监测其他受威胁生境的植被变化提供了一种方法。
Coastal plant communities are being transformed or lost because of sea level rise (SLR) and land-use change. In conjunction with SLR, the Florida Everglades ecosystem has undergone large-scale drainage and restoration, altering coastal vegetation throughout south Florida. To understand how coastal plant communities are changing over time, accurate mapping techniques are needed that can define plant communities at a fine-enough resolution to detect fine-scale changes. We explored using bi-seasonal versus single-season WorldView-2 satellite data to map three mangrove and four adjacent plant communities, including the buttonwood/glycophyte community that harbors the federally-endangered plant Chromolaena frustrata. Bi-seasonal data were more effective than single-season to differentiate all communities of interest. Bi-seasonal data combined with Light Detection and Ranging (LiDAR) elevation data were used to map coastal plant communities of a coastal stretch within Everglades National Park (ENP). Overall map accuracy was 86%. Black and red mangroves were the dominant communities and covered 50% of the study site. All the remaining communities had ≤10% cover, including the buttonwood/glycophyte community. ENP harbors 21 rare coastal species threatened by SLR. The spatially explicit, quantitative data provided by our map provides a fine-scale baseline for monitoring future change in these species’ habitats. Our results also offer a method to monitor vegetation change in other threatened habitats.
