  1. Movement measures include Meters Per Day (MPD, m), Distance Per Movement (DPM, m), Minimum Movement Frequent (MMF), and circular variance (Directionality). For Directionality, values closer to 0 indicate more linear movements. Space use measures include 100% Minimum Convex Polygon (100% MCP, Ha), 95% Utilization Distribution (95% UD, Ha), and 50% Utilization Distribution (50% UD/core use area, Ha).
