Country: Costa Rica
State: Puntarenas

Coordinate: 8° 42' N, 83° 12' W

Geography comments: "Piedras Blancas National Park covers a 148 km2 tract of land located near the town of Golfito, in the Puntarenas province of southern Costa Rica"
Climate and habitat
Habitat: tropical/subtropical moist broadleaf forest
Protection: national/state park
Substrate: ground surface
MAT: 27.0
Habitat comments: "The park is in the tropical wet forest life-zone ... and stretches from sea level to 579 m of elevation"
"The nearby town of Golfito receives about 571 mm of rain in the wet season (May through mid-November) and 251 mm of rain in the dry season (mid-November through April) on average"
"Mean annual temperature is 26.6 °C and 27 °C in the wet and dry seasons, respectively"
Life forms: carnivores, primates, rodents, ungulates, other large mammals, other small mammals
Sampling methods: no design, automatic cameras, visual
Sample size: 1004
Years: 2016 - 2018
Nets or traps: 22
Net or trap nights: 1440
Camera type: digital
Cameras paired: no
Sampling comments: "We installed five to seven cameras (Reconyx Hyperfire PC800, Bushnell Aggressor) for each sampling season, between April and November in 2016, 2017, and 2018"
"In 2017, all five cameras were subsequently moved to new locations after approximately 90 days to improve the spatial coverage of our survey"
"We installed cameras in unpaired camera stations spaced between 1.6 and 3.4 km apart at roughly 1 m above ground, and adjacent to the trail ... in areas with a relatively high abundance of wildlife"
"We programmed cameras ... to take a burst of three photographs with a less than one second interval between each photograph, and no refractory period (rapid-fire) between events"
"We defined an event as any photo-series of a species, and we considered multiple photographs of the same individual(s) within 30 min to be the same event"
"Cameras operated 24 hours a day"
"We also recorded all arboreal mammal observations while walking to camera stations in 2018"
