@MattB, I hear you there. The "Free From Brush" requirements, in my opinion, are fairly antiquated from when timber values were the only values being managed. Don't get me wrong - I absolutely appreciate the importance of maintaining a sustainable fiber supply (it pays my mortgage), but it's safe to say that absolutely everyone nowadays appreciates that myriad of other values provided by crown forest land.
I'm fortunate to be operating in a region where we have landscape level management tools and conifer, mixedwood, and deciduous reforestation standards. This provides a ton of flexibility that I am advocating for being applied province wide. Our free growing standards are being met and our best modeling suggests that our Predicted Merchantible Volume is usually head and shoulders above the Target Merchantible Volume from our landscape populations.
@MattW, I agree - there is a lot to it. It's safe to say that it's a multivariable equation.
Some researchers such as Lautenschlager out of Ontario have found that a brushing treatment further increases moose browse over time because of accessible vegetation heights being reset partway through:

...though I would argue that wholesale broadcast application of herbicides would badly impact browse availability for localized moose populations. Temporarily, but temporary during a low winter forage season still leads to mortality.
It is undisputable that some form of cumulative impacts of our land use is impacting moose populations negatively in many areas. I know that wolf and hunter access has been paraded as a major contributor, but it is something that industry (Forestry, Oil and Gas, etc) are striving to improve on.
