Trench Sept 2014_NoO

Percent cover of vascular and non-vascular species. Absolute and relative for moss species, relativized by total moss cover.

plotid = Plot ID;
Rep = Replicate;
Trt = Water level treatment (0 cm, -10 cm, -20 cm, -30 cm);
Cover = Cover treatment (HP = Herbaceous plants, LS = Low shrub, WM = Wood-strand mulch, NC = No-cover control, C = No-moss no-cover control);
Litter = Percent cover of litter;
WtoS = Soil to average water level;
Tdiff = Temperature difference between surface and 5 cm depth in the soil (C o);
SOM = Percent soil organic matter;
Weeds = Percent cover of unplanted vascular plants;
HP = Percent cover of herbaceous plants;
LS = Percent cover of low shrubs;
TMB = total moss biomass; (g) GWC = Gravimetric water content;

本数据集包含维管植物与非维管植物的盖度百分比数据。其中苔藓物种的盖度分为绝对盖度与相对盖度，相对盖度以苔藓总盖度为基准进行归一化计算。

plotid：样地ID（Plot ID）；
Rep：重复样地（Replicate）；
Trt：水位处理（Water level treatment），设置0 cm、-10 cm、-20 cm、-30 cm四个水位梯度；
Cover：覆盖处理（Cover treatment），各缩写对应处理如下：HP为草本植物（Herbaceous plants）、LS为低矮灌木（Low shrub）、WM为木丝覆盖物（Wood-strand mulch）、NC为无覆盖对照组（No-cover control）、C为无苔藓无覆盖对照组（No-moss no-cover control）；
Litter：枯落物盖度百分比（Percent cover of litter）；
WtoS：土壤与平均水位的比值（Soil to average water level）；
Tdiff：土壤表层与5cm深度处的温度差（Temperature difference between surface and 5 cm depth in the soil），单位为摄氏度（℃）；
SOM：土壤有机质（Soil Organic Matter, SOM）百分比；
Weeds：未种植维管植物的盖度百分比（Percent cover of unplanted vascular plants）；
HP：草本植物盖度百分比（Percent cover of herbaceous plants）；
LS：低矮灌木盖度百分比（Percent cover of low shrubs）；
TMB：苔藓总生物量（total moss biomass），单位为克（g）；
GWC：重量含水量（Gravimetric water content, GWC）
