Deer harvest reports are useful because deer hunters use them to identify the densest deer populations. Some states even break down their reports by county, game type and hunter type, or show them over time so that you can identify trends. Most deer harvest reports are funded in part by the purchase of hunting licenses and tags.
The real interest of this topic, for me as an information specialist, is this:
Other funding that has come from the government has been cut drastically or eliminated altogether. You will notice that some of the states have not updated their deer harvest statistics for a couple of years due to lack of funds.
