title: Global responses of plant abundance, diversity, and fitness to increased fire severity or frequency

description: Database of responses of plant abundance, diversity, and fitness to
 increased fire frequency or severity, collected from published scientific
 articles or reports. The database includes 394 studies published worldwide
 between 1962 and 2023. Information on the following variables are also
 provided: fire regime component (fire frequency or severity), time since
 the last fire, fire type (wildfire or prescribed fire), historical fire
 regime type (surface or crown fire), plant life form (woody plant, herb,
 or bryophyte), habitat type, and climate. The database underpins the
 meta-analysis 'Global plant responses to intensified fire
 regimes', published in Global Ecology and Biogeography.
description: Data was collected from published articles and reports following
 standard methods for systematic review. For details, please see the
 article 'Global plant responses to intensified fire regimes',
 published in Global Ecology and Biogeography.
description: **Description of the data and the file structure** The R code for carrying
 out the meta-analysis is provided in file
 "global_fire_analysis_240325.R". The database is provided in the
 file "global_fire_DB_240325.csv". The columns in the file are
 described below: study_id: study identification, composed of the name of
 the first author and the year of publication. study_num: study number.
 ES_num: number of effect size within study. country: country where the
 study was carried out. latitude/longitude: coordinates indicating where
 the study was carried out. FR_hist: type of historical fire regime
 (surface fire, crown fire, or non fire prone). FR_comp: fire regime
 component (frequency or severity). fire_type: type of fire (wildfire or
 prescribed fire). habitat: type of habitat (broadleaf forest, conifer
 forest, mixed forest, grassland, shrubland, or woodland). response: broad
 response variable measured (abundance, diversity, or fitness).
 response_detailed: more detailed response variable measured (e.g., size or
 biomass, density or frequency, Shannon or Simpson indices, gamma
 diversity, survival). TSF_months: time since fire in months. TSF_factor:
 factor variable of time since fire (short, 24 months or less, or long,
 more than 24 months). PLF: plant life form studied (woody plant, herb, or
 bryophyte). climate: climate prevalent in the study region (arid, cold,
 temperate with a dry season, temperate without a dry season, or tropical).
 Xtreat1_type: type of crossed factor number one. Xtreat1_fact: category
 for crossed factor number one. Xtreat2_type: type of crossed factor number
 two. Xtreat2_fact: category for crossed factor number two. surface-crown:
 type of change in fire behaviour with intensification of fire regime
 (surface to crown, surface to surface, or crown to crown). eff_n:
 effective sample size. d_Hedges: Hedges’ d. var_Hedges: variance of
 Hedges’ d. imputed: whether the effect size was imputed or not. source:
 source of the data used to calculate the effect size (e.g., Table1,
 Figure2, main text). 'NA' indicate missing values, e.g., because
 they were not reported in the source study, or because the variable does
 not apply to that study.
