Representation of dimensions of landscape-scale fuel treatment design. Green shapes depict treated areas within landscapes. Squares in vertical columns illustrate landscape scenarios that differ for the dimension listed above them. Extent: total treated area increases from top to bottom. Size: area of individual treated units increases from top to bottom. Placement: treatments arranged in a regular pattern (top), within specific zones (middle), or surrounding developed areas (bottom). Prescription: mechanical treatments (top), prescribed fire (middle), and mechanical treatments plus prescribed fire (bottom). Timing: first decade only (top), decades 1–3 (middle), and decades 1 and 3 only (bottom)
