Camera Trapping


Camera Trap Summary.  2012 Jack Childs

Beginning in April 2009 Manuel “Memo” Galaz Galaz, the vaquero who was at that time employed by J. Moreno, President, Asociacion para la Conservacion del Jaguar en la Sierra Alta de Sonora, operated trail cameras at 47 locations in the Sierra Madre Mountains of northeastern Sonora, Mexico, a mountainous dry tropical thornscrub ranging from 440 m to 1230 m above sea level.  Area covered by cameras is 410 sq km.  As of January 2012 (993 calendar days or 12,273 camera trap nights) have generated 33,000 photographs of 22 species of wildlife with feral and domestic to include humans.  Ignoring pictures of “small” birds, test pictures and “ghost” pictures with no visible mammal we analyzed 22,300 pictures of 22 species.  Four members of the Felidae – jaguar (Panthera onca-64 pictures), puma (Puma concolor-543 pictures), ocelot (Leopardus pardalis-97 pictures), and bobcat (Lynx rufus-341-pictures) – occur sympatrically with two members of the Canidae – coyote (Canis latrans-430 pictures) and gray fox (Urocyon cinereoargenteus-1933 pictures) have been documented.  The remaining approximately 18,000 photos represent 11 major indigenous potential prey (see map “teardrop” pins for taxonomic names) – Coue’s deer, collared peccary, Gould’s turkey, skunk, rabbit, squirrel, opossum, raccoon, coati, ringtail, badger are a food source for these 6 predators; as well as 5 “other” inhabitant types – human, horse, cattle, dog, cat. Our analysis program (Harris G., Thompson R., Childs J.L., and Sanderson J.G. 2010. Automatic storage and analyses of camera trap data.  July 352-360. Bulletin of the Ecological Society of America.) calculates daily activity patterns, abundance, areas of occupation of each species, and more.  Through analysis, we are able to better understand the relationships and interactions among the 22 species occupying this habitat.
