I contend the Mladenoff et al. (2006) rebuttal to my article (Mech 2006), “Prediction failure of a wolf landscape model,” itself fails. Mladenoff et al. (2006:878) provide no data to support their claim that the model “...continues to successfully predict wolf recolonization in Wisconsin, USA, over more than 25 years.” I find this critical lack of supporting data puzzling, and it substantiates why I felt obligated to publish my original cursory analysis (Mech 2006). Prior to preparing my manuscript, I tried for several years to persuade Mladenoff et al. to conduct a Geographic Information Systems test of their model using the data available from 101 new wolf-pack territories. I believe in the absence of these data, my analysis is appropriate.
