FLAG 2: MODE OF DEATH (Enter “1” in this column if the tree is alive)1) Physical mechanism of mortality (How the treedied)a =b =c =d =e =f =g =h =i =k =l =m =Tree died standingStem broken (snapped trunk; record heightof break in Comments)Uprooted (root tip-up)Standing or broken, probably standing (notuprooted) (i.e. between a and b but closer toa)Standing or broken, probably broken (notuprooted) (i.e. between a and b but closer tob)Standing or broken (not uprooted) (i.e.between a and b)Broken or uprooted, probably uprooted (i.e.between b and c but closer to c)Broken or uprooted, probably broken (i.e.between b and c but closer to b)Broken or uprooted (not standing) (i.e.between b and c)Vanished (found location, searched for treebut could not find it)Presumed dead (location of tree not founde.g. impossible coordinates, poor maps)Unknown2) Number of trees in Mortality eventp =q =r =Died aloneOne of multiple deaths in a large eventUnknown3) Killed or killerj = Anthropogenic (human causes, e.g. logging)n = Fire/burnto = Lightnings = Unknown whether killed or killert = Killeru = Killed, no more informationv = Killed by another dead tree with a brokenstemw = Killed by another tree that was uprootedx = Killed by branches from a dead standing treey = Killed by branches fallen from a living treez = Killed by a strangler2 = Killed by a liana3 = Killed by strangler/liana weight (tree diedbroken or fallen; use with ‘z’ or ‘2’)4 = Killed by strangler/liana competition (treedied standing; use with ‘z’ or ‘2’)Note: Select one code from each category. For example a dead tree that is standing, died alone and was killedby lighting would be 'apo'.For multiple deaths the numbers of trees that died should be recorded and written in the comments column.Also see the Mode of Death manual at http://www.geog.leeds.ac.uk/projects/rainfor/pages/manuals_eng.htmlFLAG 3: Measurement Technique0 = Normal/tape measurement1 = Relascope2 = Digital camera3 = Estimate4 = Ladder, with diameter tape5 = UnknownFLAG 4: Data Manipulation0 = Normal measurement, no retrospective modification1 = Extrapolated from previous measurements forwards or finalmeasurement backwards2 = Corrected expected typographical error3 = Interpolated (two good measurements either side of a problemmeasurement)4 = Estimated using median growth rates6 = The POM was changed because it had to be, good measurementbefore.7 = Zero growth rate assumed8 = Another transformation, see notes/ not clear what was doneR = Correction using Ratio between non-affected and affectedmeasurement (i.e. deformation, bark peeling)Note: Only one measurement technique and one data manipulation code should be selected for each tree.Comments: Everything else! If a tree is outside a plot, add to comments, but leave blank in census data.82
