the survey was their willingness to answer a number of open-ended questions, including one towards the end of the interview that was asked of all respondents and that generated an average of 37 words per person.

Structure of the Interviews The average interview length varied considerably with the type of owner being surveyed: a) For non-operator owners it was 30 minutes (column 3 of Table 2.2), while for operator-owners who had had conservation easements on their land for just one year (since some time in 2011), the mean was 7.6 minutes higher (37.6—column 4). b) The difference resulted from the many questions asked of operator-owners that were not asked of non-operators. Farmers and ranchers in the sample were questioned about their 2011 crops and livestock, their marketing outlets, their use of management systems (e.g., organic, Integrated Pest Management), and about any processing of agricultural products, among other potential aspects of their operations. c) If the easement took effect in 2010 or earlier, the average rose 3.7 more minutes—to 41.3 (column 5). This third group of respondents was asked additional questions—about their farm or ranch operations in the first year they both owned and operated protected land, so that the earlier operations could be compared to 2011 to learn if program participants had expanded or contracted their operations after the easement took effect.
