With required inputs, this model applies a habitat suitability model for nesting White-headed Woodpeckers in burned forests of the Inland Northwest (Latif et al. In Prep). The model is an alternate version of that provided by 'WHWO_burned' fitted to RAVG instead of MTBS burn severity data.
1 | WHWO_burned_ravg(brn_1ha, brn_1km)
|
brn_1ha |
numeric vector with length = number of observations/pixels. Values are mean percent (0-100) of 3x3 moving window neighborhood that is either severely burned (RAVG dNBR > 270) or open (pre-fire canopy cover < 10%). |
brn_1km |
numeric vector with length = number of observations/pixels. Values are mean percent (0-100) of a 1-km radius (~314 ha) moving window neighborhood that is either severely burned (RAVG dNBR > 270) or open (pre-fire canopy cover < 10%). |
The model applied here is a RAVG-based version of a Maxent model developed at two wildfire locations (Toolbox, 2002; Canyon Creek, 2015; Latif et al. In Prep).
exponent |
This value is a linear function of inputs subsequently re-scaled to get various other outputs. |
hsi |
Maxent output rescaled to range 0-1 using a logit transformation. This is the output evaluated by Latif et al. (2015) and provided by ArcGIS application tools to inform forest planning. |
mx.raw |
Raw Maxent output recommended by Merow et al. (2013) and most closely related to local abundance or density. |
