Hi Donna & All, Feb 8, 2016
The book, The Hidden Life of Trees, should be interesting reading.
But there is nothing mysterious about "...for reasons unknown, keep =
the ancient stumps of long-felled companions alive for centuries by =
feeding them a sugar solution through their roots.=E2=80=9D This is root =
grafting practiced by Spruce sometimes, Hemlock always, Fir sometimes =
and Norway Maple.
Root grafting is I suspect a reflection of somewhat hostile soil =
conditions and/or perhaps 'permanent woodland' such that extension roots =
tend to follow old root channels as opposed to making a new one. When a =
root cap of tree A meets one of tree B they sometimes (always ?) unite =
and form a 2-way link.=20
Decades ago I came across a great example of this at Dean Chapter =
Lake. The roots of the Spruce forest which had been killed by raising =
the water level for hydro were mostly intact but exposed by wash. Every =
Spruce I saw was attached to two or more Spruce by grafting.

This forest article was forwarded to me by Jon Percy. Bob Bancroft =
has also circulated around to some, but it is worth ensuring that =
everyone sees it. =20

The parts I enjoyed-

=E2=80=9C in nature, trees operate less like individuals and more as =
communal beings. Working together in networks and sharing resources, =
they increase their resistance.=E2=80=9D
=20
=E2=80=9CIn one forest, they said, when they wanted to buy a car, they =
cut two trees. For us, at the time, two trees would buy you a =
pizza.=E2=80=9D
=20
=E2=80=9C that trees in the forest are social beings. They can count, =
learn and remember; nurse sick neighbors; warn each other of danger by =
sending electrical signals across a fungal network known as the =
=E2=80=9CWood Wide Web=E2=80=9D; and, for reasons unknown, keep the =
ancient stumps of long-felled companions alive for centuries by feeding =
them a sugar solution through their roots.=E2=80=9D

This should be required reading for all personnel who =
=E2=80=98manage=E2=80=99 our forests.

If we want folks to relate to the forest on a more personal level, =
other than as a simple entity to mow down for relatively low profit, =
this way of describing our forests may be a good approach.
