SWFL RW Top3 May1 June30 2024

<p>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 aggregated into three probability classes:&nbsp;40 - 60% (class 3), 60.1 – 80% (class 4), 80.1 - 100% (class 5). Studies have shown that SWFL territories increase exponentially as class value increases.&nbsp;For a complete description of methods and interpretation of maps, see Hatten and Paradzick, 2003; Hatten, 2016.&nbsp;</p><p>The layer title (<strong>SWFL_RW_Top3cl_May1_June30_2024</strong>) is interpreted as follows:&nbsp;SWFL = Southwestern Willow Flycatcher;&nbsp;&nbsp;RW = Rangewide application of satellite model (56 Landsat-9 scenes) ;&nbsp;&nbsp;Top3cl = top three probability classes displayed on map (locations with a value less than 40% are not shown on the map);&nbsp;&nbsp;May1_June30 = range of dates that an image mosaic was created from Landsat 9 imagery, with the least cloudy images selected;&nbsp;2024 = year of image selection;&nbsp;&nbsp;Version 5 (v5) was used as the mask to mask out background noise (i.e., non-riparian features that could confuse the model).&nbsp;</p><p>Hatten, J.R., and C.E.
