Oregon Tidal Wetland vegetation and edaphic data 2010 - 2012

Data includes edaphic and vegetation field data from four Oregon tidal wetlands. National Wetlands Inventory (NWI) classification: low marsh, high marsh, and palustrine tidal marsh are included for each of the sites as a means of comparing parameters between the NWI classes and actual field data. Vegetation data include number and types of plant assemblages, non-native plant cover, and species richness. Edaphic data include pore water salinity, sediment carbon and nitrogen content, grain size and marsh surface elevation.

本数据集包含美国俄勒冈州4处潮汐湿地的野外植被与土壤学调查数据。美国国家湿地清单（National Wetlands Inventory, NWI）将各调查样地划分为低潮滩、高潮滩与林泽型潮汐湿地（palustrine tidal marsh）三类，旨在对比不同NWI分类下的环境参数与实地实测数据之间的差异。植被调查数据涵盖植物群落的数量与类型、外来植物盖度以及物种丰富度；土壤相关调查数据则包含孔隙水盐度、沉积物碳氮含量、沉积物粒度以及湿地滩涂表面高程。
