In an attempt to mitigate this issue, snakes are often translocated in an uncontrolled While much data for conservation translocation is example, both LDT and SDT were treated as two separate fashion, with little to no conservation value. To determine the most appropriate methods of translocation we reviewed available in the primary literature, the data for mitigation- studies) on 24 snake taxa, across 9 countries (Table 1). the available primary literature on studies performing translocations of snakes. We found two types of translocation: long based reptile translocations, which are often ad hoc, For each project we recorded the taxa studied, type of and short-distance. Based on the welfare of the animals involved and difficulty of achieving success with long-distance either simply does not exist or is largely inaccessible translocation (mitigation or conservation), whether the translocations, we deduced that short-distance translocations are the most favourable. We also reviewed the literature (Germano et al., 2015). In Australia, a huge number of donor population was wild or from captivity, and the on a third method - repatriating wild populations of snakes with captive-bred or captive-reared individuals, the results largely uncontrolled, mitigation translocations take place success of the project. Translocation success is hard to of which were very similar to those of long-distance translocations. In conjunction with a mark recapture study carried every year with the intent to reduce human-wildlife determine and it has been suggested that a translocation out by snake catchers in Darwin, Australia, we use our findings to make suggestions on the most appropriate course of conflicts. For example, one voluntary organisation can only be considered successful if it results in a self- action for the mitigation-based snake catching activities in Australia. The difficulty of ensuring successful outcomes for in New South Wales Australia, ‘rescued’ over 22,000 sustaining population (Dodd & Seigel, 1991; Griffith long distance translocations along with a high mortality rate meant we cannot suggest this as an appropriate method for squamate reptiles during a ten year period, with the et al., 1989). However, it can require several years of managing ‘nuisance’ snakes. Instead, we argue that short distance translocations are the most suitable for the welfare of majority of snakes translocated to another locality (Shine monitoring to make such an observation which is beyond the snakes involved. Nevertheless, no outcome will be more favourable for the snakes than to be simply released within & Koenig, 2001). However, with the evidence from the remit of many of the studies we have compiled. their home range accompanied by a change in attitude of the general public towards a willingness to coexist.
