This dataset (tab-delimited text file) contains data from 2194 Large Woody Debris (LWD) pieces that were sampled along 3330 m of shoreline in five lakes of the northern taiga of Quebec, Eastern Canada. These data were used in the article "Millennial stocks and fluxes of large woody debris in lakes of the North American taiga", published in Journal of Ecology.
Each row contains data on one LWD piece. Column headings are described below:

LWD_ID = ID of the LWD piece
Lake = Lake in which the LWD piece was collected
Shore = Shore segment in which the LWD piece was collected
Species = Species of the LWD piece (black spruce, balsam fir, tamarack)
Root = Presence of main roots still connected or not
Orientation = Orientation relative to the shoreline of the LWD piece
Charred = Presence of charcoal on the trunk or the branch tips
Crossdated = LWD piece crossdated to the calendar year (calendar) or into a floating chronology (chronology ID)
AMSDate = Radiocarbon dated LWD piece
NTreeRings = Number of tree-rings of the LWD piece
Residence_Time = Residence time in the lake of the LWD piece (year)
FirstTreeRing = Date of the innermost tree-ring of the LWD piece (year AD/BC)
LastTreeRing = Date of the outermost tree-ring of the LWD piece (year AD/BC)
FirstMesuredTreeRing = Date of the first measured tree-ring of the LWD piece (year AD/BC)
LastMesuredTreeRing = Date of the last measured tree-ring of the LWD piece (year AD/BC)
Burial = Burial type of the LWD piece
Diameter = Diameter of the LWD piece (cm)
Length = Length of the LWD piece (cm)
Volume = Volume of the LWD piece (m^3)
Distance = Minimum distance from the shore of the LWD piece (cm)
Depth = Minimum depth in the water of the LWD piece (feet)
BurialType = Burial type of the LWD piece (completely buried =3; partly buried =2; exposed =1)
Substratum = The type of underlying substratum (fine sediments =5; sand =4; gravel =3; stones =2; wood =1)
Aspect = The aspect of the corresponding littoral zone (from 0 to 2)
Exposure = The exposure to the wave action of the littoral zone (cm)
Orientation2 = Orientation relative to the shoreline of the LWD piece (perpendicular =3; parallel =2; inverted=1)
