The Powdermill IV conference was organized and chaired by Vincent Burke, Jeffrey Lovich, and Dawn Wilson, with organizational support provided by Chelonian Research Foundation, Univ. of Missouri, USGS-BRD Canyon Crest Field Station, and Univ. of Nevada-Reno.
Discussions at the conference centered to a large degree on the threats being faced by freshwater turtles and tortoises being exploited in the markets of southeast Asia and elsewhere. A press release voicing the concerns, conclusions, and recommendations of the meeting participants regarding this topic was subsequently released (see Lovich et al., next article) and publicized by the news media. A recurrent theme at the conference was the perceived need for more synergy between various turtle researchers and organizations and the need for partnering and working together through links with other organizations and individuals to help overcome the threats, both biological and organizational, faced by turtles all over the world. Several groups and organizations represented at the conference are working toward similar goals - strategic alliances between those groups and others will only help further the global efforts of turtle conservation.
