title: Deadwood stocks, dynamics and decay in the SAFE landscape

description: <b>Description: </b>Two intensive deadwood surveys were carried out in 68 permanent SAFE Vegetation Plots (plot size 25 m x 25 m). First survey was in 2017-2018 and the second in 2019.<br><br>Mode of death, decay stage, bark cover and hollowness were also recorded.<br><br>All deadwood pieces of diameter &gt;10 cm were tagged, measured, photographed and mapped. Diameter of the fallen deadwood was measured at both ends, diameter of the standing deadwood was measured at 1.3 m height or at the nearest point possible (measurement height recorded). Lenght of the deadwood was either measured (fallen deadwood pieces and shorter standing deadwood pieces) or visually estimated (tall standing deadwood pieces). <b>Project: </b>This dataset was collected as part of the following SAFE research project: <b>Decomposition of deadwood debris left over from tropical rainforest logging operations</b><b>Funding: </b>These data were collected as part of research funded by: NERC (Grant, NE/P002218/1)Sime Darby Foundation (Grant, SAFE Core data)This dataset is released under the CC-BY 4.0 licence, requiring that you cite the dataset in any outputs, but has the additional condition that you acknowledge the contribution of these funders in any outputs.<b>Permits: </b>These data were collected under permit from the following authorities:Sabah Biodiversity Council (Research licence JKM/MBS.1000-2/2 JLD.10 (104))<b>XML metadata: </b>GEMINI compliant metadata for this dataset is available here<b>Files: </b>This consists of 1 file: SAFE_DeadwoodSurvey_SAFEdatabase_2021-06-04.xlsx<b>SAFE_DeadwoodSurvey_SAFEdatabase_2021-06-04.xlsx</b>This file contains dataset metadata and 1 data tables:<b>Deadwood survey data</b> (described in worksheet DeadwoodSurveyData)Description: Two surveys of all deadwood pieces &gt;10 cm diameter in 68 SAFE Vegetation PlotsNumber of fields: 17Number of data rows: 3021Fields: <b>CensusNumber</b>: Census number (Field type: ordered categorical)<b>Block</b>: SAFE Project Block code (Field type: id)<b>Plot</b>: SAFE Project plot name (Field type: location)<b>Date</b>: Date of survey (dd/mm/yyyy) (Field type: date)<b>RA</b>: Research assistant collecting data (Field type: comments)<b>Area</b>: Sublot area within plot (Field type: id)<b>Tag</b>: Unique tree tag number (Field type: id)<b>Status</b>: Denotes wether the tree is A: Standing, B: Fallen, F: Burnt, H: Hanging or suspended, T: Stump (Field type: categorical)<b>ModeOfDeath</b>: Denotes mode of death, if known: D: Cut or killed by people, E: Unknown, C: Liana, G: Lightning, J: Other (Field type: categorical)<b>Length</b>: Length of the deadwood piece (Field type: numeric)<b>Diameter1</b>: Diameter of the deadwood, one end (Field type: numeric)<b>Diameter2</b>: Diameter of the deadwood, the other end (Field type: numeric)<b>H.POM</b>: Height of the diameter measurement point for standing deadwood pieces (default is 1.3 m, but not always possible) (Field type: numeric)<b>DecayClass</b>: Decay class of the deadwood piece (Field type: ordered categorical)<b>BarkCover</b>: Percentage of bark cover; 0 = 0%, 1: 1-25%, 2: 25-50%, 3: 50-75%, 4: 75-100% (Field type: ordered categorical)<b>HollowDiameter</b>: If hollow, the diameter of the hollow measured (Field type: numeric)<b>Notes</b>: Notes added by research assistants in the field (Field type: comments)<b>Date range: </b>2017-01-01 to 2021-06-30<b>Latitudinal extent: </b>4.5000 to 5.0700<b>Longitudinal extent: </b>116.7500 to 117.8200
