Sentence examples for fire severity measures from inspiring English sources

With few exceptions, fire severity measures (bole char height, scorch and torch height, scorch and torch percentage) and tree mortality were much lower in forest stands treated for fuels than in neighboring untreated stands.

Modelled results of two popular fire severity measures NBRdiff and NDVIdiff were compared with field data for two small wildfires that occurred in eucalypt-dominated forest near Sydney, Australia during the spring of 2006.

Fire severity, measured as total fuel reduction and litter and duff reduction, was important for predicting the magnitude of change after fire.

To address these questions, we measured pre- and post-fire tree stocking (2 years after fire) of burned forest of different pre-fire stand composition types both in salvaged and non-salvaged sites, whereas fire severity was measured in the latter only.

Fire severity as measured by crown scorch and bole char was reduced a greater distance into the fuel treatment that allowed for clumps of trees and buffers for wildlife habitat than for the fuel treatment that resulted in evenly distributed trees with complete removal of ladder fuels.

Accuracies of the moderate fire severity category for measures describing effects only to trees (percent change in canopy cover and basal area) indicated that the classifications were generally not much better than random.

Most of fire severity studies use field measures of composite burn index (CBI) to represent forest fire severity and fit the relationships between CBI and Landsat imagery derived differenced normalized burn ratio (dNBR) to predict and map fire severity at unsampled locations.

In this study, using field measured fire severity across five forest strata of dominant tree, intermediate-sized tree, shrub, herb, substrate layers, and the aggregated measure of CBI as response variables, we fit statistical models with predictors of Landsat TM bands, Landsat derived NBR or dNBR, image differencing, and image ratioing data.

We burned one randomly-chosen plot within each plot-pair during February 2013 and measured fire severity in May 2013.

Our measures of fire severity included tree mortality; height of bole char, crown scorch, and crown torch; and percent crown scorch and torch.

We additionally compared map accuracies for three measures of fire severity: the composite burn index (CBI), percent change in tree canopy cover, and percent change in tree basal area.
