File List Supplement_data.txt (md5: b4d1893fd59380fe7d7aacb04e8ab55b) Description Supplement_data.txt is a tab-separated file. It contains the data compiled from literature-sourced data, information about compilation methods, and sources. Column definitions: 1.RECORD_ID - record number. 2.SOURCE_ID - record number of reference used as data source (see list of references below). 3.SOURCE - short name for reference. 4.SITE - study site. 5.COUNTRY - country of study site. 6.REGION - region (province, state, other) of study site. 7.ECOZONE - Canadian ecozone if site in Canada or assigned to some sites in United States as the bordering Canadian ecozone. 8.SNAG_SP - tree species of snag 9.SPECIES_GROUP - species group category assigned to record based on the SNAG_SP or lead species of the study site. 10.OTHER_DESCRIPTOR - additional information about site or trees. 11.SNAG_FALL_ANNUAL - annual fall rate (%/yr) of standing dead tree stems meeting dbh criteria as Snag_Stemwood pool in CBM-CFS3 (Kurz et al. 2009). 12.SNAGBRANCH_FALLRATE - annual fall rate (%/yr) of standing dead material of non-merchantable trees, saplings, branches of merchantable-sized trees as in the SnagBranches pool of CBM-CFS3 (Kurz et al. 2009). 13.SNAGFALL_CALC_METHOD - brief description of data type used from literature source to calculate SNAG_FALL_ANNUAL, see methods in manuscript (Hilger et al. XXXX) for details of calculation methods based on T50 (mean half-life or time to 50% of snags fallen), individual % of stems fallen at a given time(s), or where values were derived from exponential k values. 14.SNAGBRANCH_FALLRATE_CALC - brief description of how data in reference was used to calculate SNAGBRANCH_FALLRATE.
