Depends on the type of tree -- pine trees do benefit from the acidification of soil via their dropped needles - it reduces competition.

Yes, but again, it don't think it's evolutionary strategy, rather than the content of the needles is what is needed, and the acidification is just a knock on effect. Pines in particular are disturbance specialists - they take off after fire, and drop relatively few needles during establishment when competition from grasses and other plants is at the highest. When they get larger they don't have to worry (,as it were) because you can choke out anything below you just by being big

It is very interesting though to walk through a pine stand after walking through a stand of mixed hardwoods. There is almost no undergrowth. It's a very different character.

Are boreal pines disturbance specialists too?
