Description: The SWFL satellite model outputs a continuous range of model probabilities (Hatten and Paradzick, 2003). In this layer, a probability threshold was set at 40 percent. Thus, areas with model probabilities less than 40% were considered less suitable breeding habitat and were excluded from the map; model probabilities greater than 40% were converted to a value of one and displayed in the map. At a 40-percent cutpoint (binary habitat map), 88 percent (667) of flycatcher territories were located inside predicted habitat in 2014, whereas 12 percent (91) were located outside predicted habitat (omission) (Hatten, 2016). For a complete description of methods and interpretation of maps, see Hatten and Paradzick, 2003; Hatten, 2016. <br />The layer title (SWFL_RW_Pr40_May1_June30_2018_v3) is interpreted as follows: SWFL = Southwestern Willow Flycatcher; RW = Rangewide application of satellite model (57 Landsat-8 scenes) ; Pr40 = binary habitat map, with probabilities greater than 40% aggregated to a value of 1; locations with a value less than 40% are not shown on the map; May1_June30 = range of dates that an image mosaic was created from Landsat 8 imagery, with the least cloudy images selected; 2018 = year of image selection; v3 = the version of mask that was used to mask out background noise (i.e., non-riparian features that could confuse the model). <br /><br />Hatten, J.R., and C.E.
