Name: Western Yellow Billed Cuckoo Distribution Model (CNHP 2015)
Display Field:
Type: Raster Layer
Geometry Type: null
Description: Species data was insufficient to do an inductive model, so a deductive model based on habitat type was cre-ated instead. Characteristics of home range size and important habitat were taken from BNA Online (Hughes 1999). Pinyon-juniper, oak shrub, and woody riparian areas within 220m of each other were selected, in addi-tion to designated Critical Habitat polygons. Contiguous habitat areas = 3 ha were retained. The model was restricted to the HUC10 watersheds that overlap the 2014 Proposed Rule depiction of designated critical habi-tat (FR-79-158-2014). Environmental Inputs: * National Wetland Inventory woody riparian * SWReGAP vegetation types: - Colorado Plateau Pinyon-Juniper Woodland - Rocky Mountain Gambel Oak-Mixed Montane Shrubland - Colorado Plateau Pinyon-Juniper Shrubland - Rocky Mountain Subalpine-Montane Riparian Shrubland - Rocky Mountain Lower Montane Riparian Woodland and Shrubland - Invasive Southwest Riparian Woodland and Shrubland

Geometry Type: null
Description: Species data was insufficient to do an inductive model, so a deductive model based on habitat type was cre-ated instead. Characteristics of important habitat were taken from BNA Online (Sedgewick 2000). As a proxy for spatial representation of high quality, continuous woody riparian areas in Southwest Colorado, both SWReGAP Rocky Mountain Lower Montane Riparian Woodland and Shrubland and National Wetland Invento-ry riparian areas were used. All areas within 300m of where both occurred were selected to include surround-ing fields and meadows. The model was restricted to the portion of southwest Colorado adjacent to the spe-cies' known range in neighboring states and as depicted in the 2011 Proposed Rule for designated critical habi-tat (FR-76-157-2011). Environmental Inputs: * Areas within 300 m of well-represented woody riparian (described above)

Name: Northern Leopard Frog Distribution Model (CNHP 2015)
Display Field:
Type: Raster Layer
Geometry Type: null
Description: This is a MaxEnt (v. 3.3.3e) inductive model. Environmental Inputs used are listed below. The state of Colorado was the modeling extent. Colorado Natural Heritage Program (CNHP) Element Occurrence Records (EORs) were used as known locations for the species. Initial cut-off of 0.295 was deemed too low, so that model results with a value of 0.7 or greater were retained for use in Marxan, based on model logs and expert review. The output extent was not modified (no mask was necessary to limit extent to known range). This model has been reviewed by Colorado zoology and wildlife professionals. The model is based on 63 EORs and 646 Observations, which were translated into 846 input points. 631 input points used for training, 157 for testing. Training AUC is 0.883, test AUC is 0.879 Environmental Inputs (variable importance): * Distance to water (37.8%) * Elevation (31.7%) * Vegetation type (16.2%) * Distance to wetlands (10%) * Landform (4.3%)
Description: Predictive species distribution model for boreal toad in Colorado. This is a MaxEnt (v. 3.3.3e) inductive model. Environmental Inputs used are listed below. The state of Colorado was the modeling extent. Colorado Natural Heritage Program (CNHP) Element Occurrence Records (EORs) were used as known locations for the species. Model results with a value of 0.150 or greater were retained for use in Marxan, based on model logs and expert review. The output extent was modified with a mask to limit extent to known range. This model has been reviewed by Colorado zoology and wildlife professionals. The model is based on 120 EORs, which were translated into 652 input points. 522 input points used for training, 130 for testing. Training AUC is 0.954, test AUC is 0.951 Environmental Inputs [percent model contribution]: * growing degree days [52.1%] * distance to water [38.2%] * summer precipitation [4.1%] * vegtype [3.3%] * landform [1.7%] * elevation [0.7%]
Name: New Mexico Jumping Mouse Distribution Model (CNHP 2015)
Display Field:
Type: Raster Layer
Geometry Type: null
Description: This is a Random Forest inductive model. Used proposed designated Critical Habitat (FR-78-119-2013) poly-gons and areas from Friggens et al. (2013) New Mexico meadow jumping mouse current suitable habitat model that extended into the state of Colorado to generate presumed presence points for the species. Model results with a value of 0.4 (40% probability of occurrence) or greater were retained, based on model perfor-mance statistics and initial review. The extent of the model was restricted to areas hydrologically connected to the Critical Habitat and NM model areas. The model is based on 200 generated presence points. 150 points were used for training, and 50 points were used for post-model evaluation. Both training and evaluation AUC are 0.991. Environmental Inputs (variable importance): * Distance to water (98.6%) * Elevation (0.7%) * Soil depth (0.4%) * Annual precipitation (0.2%) * Distance to riparian (0.1%)
