First records of 5 allochthonous species and subspecies of turtles (Trachemys scripta troostii, Mauremys caspica, Mauremys rivulata, Pelodiscus sinensis, Testudo horsfieldii) and new records of subspecies Trachemys scripta elegans in Latvia

Abstract

The aim of the research was to investigate the presence of allochthonous species of turtles in the nature of Latvia, as well as to withdraw them from the nature according to the "Plan on protection of Emys orbicularis in Latvia", officially approved by the Latvian Ministry of Environment (Pupiņš & Pupiņa 2007a). The methods of the research were: 1) information campaign and survey; 2) interviews with inhabitants; 3) field expeditions; 4) laboratory study of viability of found turtles. In course of research, five new allochthonous species and subspecies of the turtles were recorded for the first time, and new data were obtained about finding Trachemys scripta elegans in the nature of Latvia. Most of the registered animals (80%) were removed from the nature. Since allochthonous turtles get there in the result of escape from pet-lovers and, apparently, illegal introduction into nature by their owners, education of population is of great importance.
