BRT kelp forest model Hordaland, main area, 2012

Region: The county Hordaland

Number of field observations: 637

Field sampling year: 2004, 2005,2009, 2010

Prevalence: 34%

Presence / absences: 215/422

Method: BRT run with the R-package Dismo.

Number of predictor variables: 23

Information about the predictor variables: DEM (25 m resolution), slope, aspect, curvature at detailed, medium and coarse resolution (i.e. applying a 125, 525 and 1025 m moving calculating window respectively, based on the 25 m resolution DEM); wave exposure, latitude, longitude, and optimal radiation index, all with 25 m resolution; and maximum surface and seafloor current speed, slope of maximum surface and seafloor current speed, minimum surface and seafloor current speed, standard deviation of seafloor current speed, 10 and 90th percentile of surface and seafloor current speed, all current speed predictor variables with 200 m resolution, but resampled to 25 m.

AUC independent data: 0.88
