Impact of Harvesting Wild Mushrooms - Cut versus pick

I found this link on one of the facebook mushroom sites. http://www.fungimag.com/spring-2012-articles/LR_Agaricidal.pdf
I thought it was pretty interesting. Anyone on here a part of the Oregon study? What are your opinions on the impact of harvesting on long term sustainability?
My own opinion is that respectful and non-commercial harvesting of wild mushrooms has no impact on wild mushroom populations or sustainability, at least none that I've been able to discern by having boots on the ground and picking Porcini in the same patches for more than 30 years.
Weather and the actions of man (logging, habitat loss due to development, fire fuels reduction efforts, raking to remove the duff layer and expose immature mushrooms) are much more likely to reduce populations of wild mushrooms and cause reliable patches to disappear.
Over the years, I've seen California go from zero regulations on harvesting wild mushrooms to a free permit with unlimited quotas for non-commercial pickers, to the latest regulation which requires a permit and limits each individuals harvest to 10lbs of mushrooms per season, or a collection window of 30 days total. (And don't even get me started about the insane regulation to cut any mushroom with a cap of 4" dia or larger into four pieces, while still in the field).
And because I don't want to be cruel and post a thread without a mushroom pic, here's a gorgeous Amanita in the Vaginatae complex that my wife took last November with her iphone 6s.

And another (non-fungal) of a flower, while I was experimenting with CombineZP. This photo is comprised of around 20 images.

Is that flower indoors? I find that wind and changing light levels can be problematic when trying to focus-stack outdoor images.
With regards to the mushrooms, I've often wondered if sometimes we don't inadvertently spread the mycelium by pulling up the mushroom.

Yes, this one is indoors. Outdoors wouldn't have worked because of wind movement, as you mentioned. Have you tried CombineZP? I think it corrects differences in lighting before stacking.
This one is outdoors. Not a very exciting subject for an image stack, but I like the way it turned out. http://mushroomobserver.org/221325?q=2fa1x

The only one I have tried is Heliconfocus.

Here's a link to CombineZP if you want to give it a try.

Toggled as favorite. I'd like to see responses to the topic at hand.
Personally? I literally apologized to a pin that came up while moving litter. I'm at a point in which I'm going to paint the town with spore solution, or just spray my boots before walking through the grass.
I'd like to do whatever I can to give back to something from which I've taken.
Seeing what has happened to Astoria and Hammond for azzies, and Salem for cyans, I'm very much troubled at the environmental impact. If people don't stop messing up certain parks, digging up woodchips, flapping lips about where actives are... I don't know.. I could go on forever on this topic. Even if I pick an inactive by mistake I'll do what I can to get it back in the dirt where it came from, or near another fruit body.
If Oregon has been doing logging and replanting sustainability for 44 years and beach cleanup for 21, you'd think mushroom observers/hunters would have more respect for these areas but clearly they don't. Worst part of some of the dunes is that tourist season is over and it's all fresh, so it's primarily locals.d
Sorry to stray from the topic a bit but that's where I stand.

The results of the study being conducted in Oregon seem to show that even harvesting every single mushroom in a plot has no detrimental affect on next year's fruiting. It even seems to show that cutting versus ripping them up doesn't make much difference.
I posted it because it goes contrary to so much of what I've read.
I'd never advocate a lack of respect when collecting, but that's more of a general respect for our wild and beautiful places rather than a fear that mushrooms won't grow there in future.
