Discussion on another thread brought up the accuracy of harvest statistics and mandatory reporting and how effective it is. I didn't want to hijack that thread any further so I'm continuing that topic here.
Another poster commented that he had heard from a biologist that the response rate on mandatory reports in Idaho was near 10% and all harvest data was extrapolated from there. I honestly didn't know how accurate that might be so I tried to find out.
The most recent information I could find for harvest reporting came from 2015. In that year, 61% of mandatory reports were completed voluntarily online. (157,612 out of 254,785). To estimate bias from non-compliance, IDFG attempted to call a random sample of 50,000 of the remaining hunters by telephone to obtain their harvest reports (increased from 40,000 in 2010).These hunters were called in December 2014 and January 2015. This phone sample was larger than in 2009-2010, and four times as large as in 2006. The harvest results from the telephone sample were used to estimate the harvest by hunters who did not file reports.
The 2015 info didn't specify how many reports were collected by telephone but the same effort in 2013 collected another ~30,000 reports. If 2015 produced similar results it would mean that IDFG collected harvest reports for ~75% of deer/elk/pronghorn hunters. I would say that is encouraging and definitely lends some credibility to the harvest statistics. There is also room for improvement.
I would think it would be pretty simple for the licensing system to prevent anyone from purchasing a hunting or fishing license until they have completed their harvest reports from the previous year.
