If one were to graph the tree's lifetime, the upward trend toward
increasing well-being might be thought of as peaking, leveling off, then
declining. Those stages might be seen in some species and/or conditions as
being short or long in time, as in, say, an *Acacia* sp. or in a Sequoia.
The Great Basin bristlecone pine, for example, can remain in a declining
state for a very long time. There are a lot of variables, and the truth is
in the details.

Yes, me too.  I meant use the life stage numbers, rather then the terms
ancient and so on.

One could, but personally I am weary of the using ‘Ancient’  in the almost
ubiquitous nature with which it is banded about arboriculture nowadays, it
is far to vague and emotive, and as Kevin alluded to earlier, is often
misused within the planning system.

Senescent does imply ultimate death but I would suggest it is the phase
following the trees optimal growth & vitality prior to natural, not
induced, decline, one could use  ‘Ageing’ as it refers to degenerative
changes that occur in all organisms without any reference to death, while
‘senescence' might imply the developmental stage at which close to death'
symptoms becomes apparent.  Given the regenerative powers of some trees
through vegetative propagation and management practices such as coppicing,
pollarding and layering, one word for the processes of decline seems a
little restrictive. Each to their own maybe.
