“…After confiscation by relevant national law enforcement agencies, the gorillas were placed under the care of authorized facilities for their care and rehabilitation before entering the reintroduction program (Courage et al 2001;Farmer and Courage 2008;Hayman et al 2010;King et al 2005aKing et al , 2009). Forty-three wild-borns were released between 1996 and 2006.…”

Postrelease monitoring is an important aspect of reintroduction projects, one outcome of which is to allow an assessment of the initial success of the reintroduction, often measured by quantifying survival and reproduction rates. In long-lived species, accurate estimations of demographic parameters are difficult to obtain, and therefore assessment of reintroduction success in such species is challenging. To assess the initial success of a reintroduction program for the long-lived, slow-reproducing, and critically endangered western lowland gorilla Gorilla gorilla gorilla, we analyzed postrelease monitoring data from 2 reintroduced populations, in the Batéké Plateau region of the Republics of Congo and Gabon, to quantify several demographic parameters, and compared our results with published data on wild gorilla populations. Annual survival rate of the 51 released gorillas was 97.4%, 9 females gave birth to 11 infants at an annual birth rate of 0.196 births per adult female, and first-year survival of the infants was 81.8%. Annual birth rate within the reintroduced populations is not significantly different from that given for wild western gorilla populations, and other demographic parameters fall within the range of published data for wild gorilla populations. Our analysis illustrates that the reintroduction program has been successful in terms of the initial measures of postrelease survival and reproduction, and our quantitative data should facilitate the development of a population model that can predict the probability of population persistence and therefore provide an indication of longer-term reintroduction success.

“…The trade can be exacerbated when members of the public purchase the animal out of pity and then surrender it to a nearby facility (Harcourt 1987, Karesh 1995, Farmer & Courage 2008, Beck 2010. Additionally, rescue centres and zoos create a humane outlet for the confiscated animals and thereby potentially reduce the pressure on governments to deal with perpetrators (Harcourt 1987, Cuarón 2005, Sumrall 2009).…”

“…The process of trial and error is often repeated every time a new centre is established (Teleki 2001). The goals of each centre are determined by the owners -often based on personal judgement -in isolation from other centres (Teleki 2001, Carter 2003, Farmer & Courage 2008. Some authors have criticised the methods employed by rescue centres, without offering practical alternatives (Teleki 2001, Carter 2003.…”

“…A major criticism of translocation programmes is the lack of documentation and subsequent publication of results in the scientific community (Beck et al 1994, Yeager & Silver 1999, Fischer & Lindenmayer 2000, Carter 2003). The reasons for lack of communication appear to be related to fear of condemnation by authorities or funding agencies as a result of the failure or improper implementation of such projects (Teleki 2001, Farmer & Courage 2008. Nevertheless, without such information, progress in the field of rein troduction science will undoubtedly be hampered by a lack of comparable data -both successful and unsuccessful -from which modifications can be made accordingly (Fischer & Lindenmayer 2000, Seddon et al 2007.…”

With the number of threatened species in rescue centres rising, scientific reports on the functioning and success of such centres is essential. Compassionate conservation tries to bridge the gap between animal welfare advocates and conservation biologists, recognising the benefits of preserving a species and its individuals. A case in point is that of Indonesia's threatened slow lorises Nycticebus spp., where illegal trade is decimating wild populations of these primates. We present 4 yr of data from Ciapus Primate Centre in Indonesia, which received 180 slow lorises between 2008 and 2011. We show that > 85% of these primates were unsuitable for reintroduction; 23 slow lorises that were deemed suitable for reintroduction were released to the wild between 2010 and 2013 and were followed with radio tracking. Eleven of them died (on average 76 d post-release), 1 was recaptured (148 d post-release), 6 are no longer being monitored (after, on average, 263 d post-release) and their status is unknown, and 5 are still being monitored (average 226 d post-release, as of December 2013). The challenges posed by work with slow lorises in the Ciapus Primate Centre over these 4 yr, with release success highly variable, show that even with concerted effort, rescue centres need to consider alternative options. We review such options, considering the pros and cons of euthanasia, life in captivity and reintroduction to the wild. We conclude that in today's global conservation crisis, it can only be beneficial to combine the expertise of animal welfare practitioners and conservation biologists.

“…allows authorities to confiscate primates and thereby enforce laws against the ownership or trade of wild primates (Cress 2006;Eccleston 2008;Farmer and Courage 2007). However, as the flood of primate confiscations continues, many sanctuaries have recognized the need to become more than primate repositories and take a leadership role in addressing the problem.…”

Education Program Evaluation at Multiple Primate Sanctuaries in Equatorial Africa

et al. 2011

The past decade has witnessed a shift in the role of primate sanctuaries in Africa from warehouses of salvaged animals to proactive conservation organizations. As part of this new role, the Pan African Sanctuary Alliance (PASA) has conducted annual training workshops for educators from member sanctuaries. These workshops have included content on program development, interpretive techniques, and evaluation techniques. Here we use meta-analytic techniques to examine data from the resulting education evaluation programs for trends in knowledge acquisition across PASA sanctuaries. Question content strongly impacted the evaluation results of the conservation education program. In addition, effect size and final performance scores were independent of one another and provide different perspectives as to the effectiveness of a conservation education program. These results highlight the importance of using both final performance scores and effect size measures in conservation education program evaluation. They also underscore the importance of evaluating knowledge transfer as part of the larger picture of evaluating pro-environmental behavior change and conservation impact.
