Abstract

This study aims to evaluate different wild fauna release processes carried out in Colombia, in which the monitoring and tracking was documented during the period from 1997 to 2015. Data collection was performed at Environmental Authorities documentation centers, Non-Governmental Organizations (NGOs), and institutions that work with wildlife, and management reports of the 33 Regional Autonomous Corporations during the years 2007-2013, as well as scientific papers published in specialized journals and proceedings of scientific events. Sixty-six case studies were identified of which 47 were releases of mammals (293 specimens), 16 releases of birds (372 specimens) and 3 releases of reptiles (7 specimens). The objective of releasing mammals was mainly the population reinforcement, while in birds and reptiles the objective was directed to conservation programs of endangered species. The releases of mammals and birds corresponded mainly to species categorized by the International Union for Conservation of Nature (IUCN) as minor concern, and released reptiles in the category Critically Endangered (CE). Mammals and reptiles were mainly marked with radio transmitter, and birds were marked with rings. The most used monitoring techniques in mammals and birds were direct observation and telemetry, and telemetry in reptiles. Follow-up and monitoring times for mammals, birds and reptiles varied mainly in the range 1-30 days. According to the defined criteria in each case study, 57.4% of mammal releases, 68.7% of birds and 66.6% of reptiles were considered successful.
