Mulch is used as a weed suppressant,for moisture retention and to "darken"
soil on developments, I think it is poor for the first, outperformed
by modern artificial treatments for the second and a fraud for the
third.
I'm not sure that is entirely borne out in the research papers and literature.
There's no doubting the efficacy of herbicides, but we have certainly
had reasonable results in farm woodland establishment trials with
mulch as a weed suppressant. I also seem to recall that the most
recent ISA research (2000?) showed mulches performing pretty much as
well, if not better than other soil ameliorants.

Perhaps I misunderstood your posting, but a 2ft-deep mulching around
your beech tree could reasonably described as over-egging the cake!
Not a good idea.
