Table 3 Criteria for critical appraisal and data extraction from studies selected after full text screening

From: Comparative effectiveness of silvicultural interventions for increasing timber production and sustaining conservation values in natural tropical production forests. A systematic review protocol

Main sections

Criteria for critical appraisal

Data extracted

Description of the study site

 

Latitude and longitude of sites

  

Data on climate, topography, geology and soils

  

Population size, main cities, main economic activities

Population

 

Type of forest indicated from which a standard list can be compiled for ease of comparison

  

Basal area, timber volume before logging, biomass, number of trees, and other inventory metrics (to be developed iteratively)

Methods

Clear and repeatable methodology

Number of plots, treatments, blocks, replications (see also below)

 

Adequate description of silvicultural treatments

Logging intensity (m3/ha, basal area removed, number of trees removed, biomass removed)

 

Replication - at least 3 plots or treatments

Number of plots/treatment

 

Outcome measured after intervention

Number of years after silvicultural intervention

 

Spatial autocorrelation between transects

 

Results

Validity or reliability of data

Data for mean and SD

  

Size of the sample

 

Randomized sample

Y/N

 

Variables measured allow the effect of the intervention to be assessed

 
  

% recovery of timber volume

  

% recovery of biomass

  

Biodiversity (floristic, faunistic, indicators)

  

Other quantification or indicators of ecosystem services

  

Measures of socio-economic outcome (including poverty, human health & well-being, livelihoods, social capital, social welfare, empowerment, equity, based on Pullin et al. (2013) [14])

  

Type of models (matrix, individual based)
