According to a 2011 DNR analysis, the state’s forest products manufacturing and related
sectors directly contributed $3 billion value-added to the Minnesota economy. As of 2012, over
eight million acres (roughly half) of forests in Minnesota were certified for sustainable forest
management through a voluntary third-party process.
In 2005, a forest certification audit noted that deer browse in certain areas of the state was
contributing to regeneration failures as well as possible loss of other plant species. Continued
certification of the state’s forest lands required demonstration by the DNR that deer
population targets were consistent with ecosystem health goals.
While there is a natural assumption that deer damage to natural vegetation is related to high
deer densities, in some situations damage can occur even where deer population size is not
considered high.

Add to that poor pine regen isn't a crime of browsing, but rather a lack of fire. DNR's own Itasca State Park study said as much.

There is another chart that I can not copy, that indicates peak harvest numbers were about 2002-2005

The OLA report was also distributed to them. Here are some highlights.
Key Recommendations: DNR should develop a deer management plan that defines and prioritizes DNR resources, goals, and objectives, and includes strategies to improve and maintain adequate deer hunting and wildlife viewing opportunities. (p. 63) DNR should improve its resources for estimating deer populations; specifically, DNR should conduct field research to collect and utilize more information about Minnesota’s deer, and to validate DNR deer population estimates. (pp. 39-42) DNR should improve its statistical methodologies, deer model data, and records management system to better simulate changes in deer populations and reduce the risk of staff mistakes. (pp. 39-42) DNR should expand the data and information it uses and provides to Deer Advisory Team members when setting deer population goals. Such data would provide better insight on local deer environments, deer survival rates, deer impact on local environments, and individuals’ perspectives about deer. (pp. 42-43) DNR should continue with its process to update deer population goals across the state, as defined within a formal deer management plan

So, the DNR can use "deer damage" as a "reason" to reduce deer densities even when those densities aren't high.

Not to jerk us off completely into left field, but I wonder if any objective quacks have studied the changes in forest ecology since the air was cleaned up? My dirt up north has almost zero sulfur in it.

There was a study from out east (PA maybe) that showed changes in forest understory were just as likely due to soil acidification from precip as from deer damage. It was discussed on both of the old forums I think.
