Coordinate: 12° 47' 21" S, 71° 23' 28" W
Coordinate basis: stated in text

Geography comments: "within the Manu Biosphere Reserve"

Environment
Habitat: tropical/subtropical moist broadleaf forest

Altered habitat: secondary forest

Protection: biosphere reserve

Substrate: ground surface

Habitat comments: "The study site... consists of ∼800 ha of regenerating lowland tropical forest" and specifically "completely cleared and now regenerating forest" that was previously converted "to agriculture for coffee and cacao"; "Major human disturbance had started ∼50 years prior to the study and lasted for 20 years before systematic human disturbance activities were abandoned in the 1980s"

Methods
Life forms: frogs,salamanders

Sites: 20

Site length: 2000

Site width: 4

Sampling methods: line transect,hand capture

Sample size: 162 captures or sightings

Years: 2012 - 2014

Seasons: dry,wet or monsoon

Sampling comments: "Surveying was conducted through both wet and dry seasons between March 2012 and May 2014... Sixty sampling locations (each consisting of 100 m long × 4 m wide transects; surveyed up to two metres in height; Folt and Reider, 2013) were established... twenty within CCR... Each transect was surveyed between 13 and 22 occasions... Individuals captured during nocturnal transects were released behind the searchers" and there were specifically 66 "samples" pertaining to CCR
