• Scientific reports or studies relevant to the question of any non-native constricting snake’s ability to become established or extend their range in the U.S. published since August 2010;
• Studies relating to any of these five species describing the habitat requirements, physiology, biology, or other factors potentially relevant to the question of their ability to become established and spread in the U.S.;
• Information relevant to the residual population of boa constrictors established on the Deering Estate, including information on first establishment, factors explaining the population’s failure to expand, ecological conditions on the Estate, etc.;
• Scientific reports or studies relating to the relative merits of climate matching, ecological niche modeling, and other scientific methods for predicting the ability of non-native species to become established in a new environment (including the effects of using mean temperature versus temperature extremes on model performance) published since August 2010;
• Critiques of Reed and Rodda (2008) (Giant Constrictors: Biological and Management Profiles and an Establishment Risk Assessment for Nine Large Species of Pythons, Anacondas, and the Boa Constrictor, USGS Open File Report 2009–1202); Reed and Rodda (2009) (What parts of the US mainland are climatically suitable for invasive alien pythons spreading from Everglades National Park? Biol Inv 11:241–252); or other like reports published since August 2010;
• Information can be in the form of citations or bibliographies of relevant research, although a brief description of the report’s conclusions or relevance to the listing issues would be appreciated. Copies of particularly relevant reports or studies, such as new critiques of Reed and Rodda, climate matching/ecological niche studies pertaining directly to constricting snakes, or information pertaining to any of the five species’ ability to become established in the U.S., would be very much appreciated. USARK would like to incorporate such information directly into its comment letter.

• A significant amount of time has passed since the last opportunity for public comment closed in 2010.
• Substantial new biological and economic information has become available since the end of the last comment period.
• The proposed listings will have severe educational, economic, conservation and scientific impacts, and therefore adequate time for submissions is necessary.
• Tens of thousands of responsible pet keepers will also be negatively affected.
• Reptile owners are a diverse group, so extra time is needed to ensure that all concerns are heard. This is particularly true for military service members.
