... B-1 A P P E N D I X B User Guide for the Landscape Prioritization Model for Roadside Habitat for Monarchs Landscape Prioritization Model Roadside Habitat for Monarchs Model Overview The Landscape Prioritization Model of Roadside Habitat for Monarchs analyses and combines factors related to monarch habitat suitability along roadways. The model helps roadside rights-of-way managers assess how the roads in their state relate to landscape-scale factors affecting monarch habitat quality.
