Kill / Die -
Die and kill are not the same. As trees
die slowly, they increase the amount of exudates into the rhizosphere.
When trees are killed suddenly and taken away, this does not happen.
Killing and Dying - When living branches on mature
trees are cut or when the tree is topped, the parts are killed suddenly.
There is a difference between dying and killing. Killing prevents
recycling of materials. The roots are the first to suffer. (Be
careful with data on this subject from tree seedlings and from current nonwoody
growth on trees. Transport in seedlings and current growth is similar to
that in annual plants. In annual plants, xylem and phloem may transport
in either direction.) More
on the topic: The review of Samuelsson et al. (1994) on CWD states that
distinct Succession of bryophyte and lichen communities occurs as trees die,
fall, and decay.
