Abstract
Ground-based photo monitoring is repeat photography using ground-based cameras to document change in vegetation or soil. Assume those installing the photo location will not be the ones re-photographing it. This requires a protocol that includes: (1) a map to locate the monitoring area, (2) another map diagramming the photographic layout, (3) type and make of film such as Kodak Elite-2®, ASA 200, (4) specific instructions for doing the photography, (5) instructions for when to re-photograph. Use a meter board to identity the topic of interest, to orient current and repeat photographs by focusing on the "1M'' of the board, to ensure maximum depth of field by focusing on the "1M," and to provide a measured reference for grid analysis of change.
