AUTHORS. Anne Lacy, Andy Gossens - International Crane Foundation

ABSTRACT. Crop damage to germinating corn by Sandhill cranes has long been a problem for farmers in the upper Midwest. It is becoming more of an economic burden to growers as the crane population expands. Research conducted by the International Crane Foundation has shown that Sandhill Cranes can damage from 20-50% of untreated corn fields in high risk areas (within 1.2 km of wetlands in high crane density areas). However, our field testing has shown that treating seeds with a coating based on the naturally occurring chemical 9, 10, anthraquinone, the damage can be reduced to nearly zero, despite heavy field use by cranes. We believe that by building a strong collaboration of partners that have a stake in the issue, we have helped create a lasting remedy to this problem. A seed treatment is an effective, long term solution, as opposed to previously recommended deterrence methods that merely move the problem elsewhere. However, the fact that high numbers of depredation permits are still being issued for damage in corn growing states that host summering cranes indicate that knowledge of this solution - though widely available - is still lacking. I will outline what our decades' worth of research and collaboration have shown that makes this method successful, and how landowners are willing to deploy the substance on their own, avoiding expensive and antagonistic compensation programs.
