The argument is that trees showing physiological strain are not always 
senescent.  Trees can decline in health and then recover - there are many 
recorded examples of this.  Therefore 'senescence' can be a misleading term.

Just how does "rejuvenescence"come about in a senescent tree?

See p 27 of said publication "Senescence in trees might therefore be
thought of as an elastic condition that may persist for decades or hundreds
of years. While senescence may progress to terminal decline, it also may
undergo a transition under the influence and the stimulation of
rejuvenescence, and go on to repeat earlier stages of the life cycle."

"Rejuvenescence", now that's a nice word and one I hedn't seen before.

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.
