Image source / rights / location / region / date / viewpoint: Photograph, satellite image, model or generated illustration: Visible emergent crowns / canopy / understory / forest floor: Scale reference / uncertainty: Edge / neighboring land use / known clearing history: Potential connections / species evidence: Observation: Inference: Evidence needed to test inference: Fictional geometry: One 1,000 m square: area 1,000,000 m2; perimeter 4,000 m. Four separate 500 m squares: same total area; combined perimeter 8,000 m. With an invented 100 m inward edge band: Large interior = 800 x 800 = 640,000 m2. Four small interiors = 4 x 300 x 300 = 360,000 m2. 100 m is an exercise assumption, not a general ecological threshold.
