These data were collected as part of management actions to remove feral swine in Texas and Oklahoma from 2005-2013 by USDA-APHIS-Wildlife Services. The "SiteNumber" is a generic identifier indicating the property in which removal events were conducted. The county and state information are provided for each property. The effort by pass represents the number of hours in a helicopter at that property at that pass. The number feral swine removed per pass is given as well.
