System failure from ailing water transport advises How Trees Grow Old, according to a Tennessee Urban Forestry Council and University of Tennessee Residential and Community Forestry co-sponsored webinar Thursday, Jan. 18, 2004.
Southern Regional Education Board Executive Director Skip Kincaid broaches trees as living organisms braving water transport, pests, gravity and catastrophe in independent, co-working, common-goaled Nature systems. He commends to How Trees Grow Old webinar attendees A New Tree Biology and Modern Arboriculture – Touch Trees by Alex Shigo (May 8, 1930-Oct. 6, 2006). A New Tree Biology describes a system as a collection of related or unrelated collectees, collectors and processes that all defer to predetermined goals or objectives.
The webinar How Trees Grow Old digitized by Katie Donaldson, moderated by Neil Letson and presented by Executive Director Kincaid equates tree-collective system with forest-collective entity.
Bristlecone pine trees (Pinus Balfourianae), with their lifespan of a couple thousand years, feature among the longest-lived trees on the blue- (and green-) marbled planet Earth.

Bristlecone pine trees (Pinus Balfourianae), with their lifespan of a couple thousand years, feature among the longest-lived trees on the blue- (and green-) marbled planet Earth.
Natural- and urban-forest trees versus urban-forest trees senescently, traumatically guard xylem cells too gashed, too gored for hydrogen-bonded water-molecule transport versus urban heat island-generating negative surfaces. Natural- and urban-forest trees and their associates, such as soil-held bacteria and other microorganisms, respectively honor their collective-entity inclusivity with most mass and most numerous populations. Catastrophic-event stresses such as people-, pest-, place- and weather-initiated events; failure such as wood structure or as root- and water-transport systems injure natural and urban forests.
The webinar How Trees Grow Old digitized by Katie Donaldson, moderated by Neil Letson and presented by Executive Director Kincaid judges senescence catastrophe-joined, structure- or system-jeopardized.
Disease, injury and stress kindle old age from human cells not dividing even as they kindle dieback top downward and lower-stature, wide-trunk retrenchment against trees wind-toppling.

Disease, injury and stress kindle old age from human cells not dividing even as they kindle dieback top downward and lower-stature, wide-trunk retrenchment against trees wind-toppling.
Gravity-lynching, negative-pressure capillary action lifts root-lodged water molecules through xylem vascular cambium, to stomata openings even as gravity-loving, positive pressure launches photosynthetic starch- and sugar-laden phloem. Whatever menaces nutrient, oxygen, sunlight and water mandates and protective-bark, energizing-phloem and moisturizing secondary-xylem growth rings makes for marred self-defensive, upright growth that response growth mitigates. External forces and internal decay respectively necessitate response growth as flexure, reaction or tension and compression wood for the former and wound wood for the latter.
Wood-structure building-blocks cellulose, flexible-stringed, strong-stringed under tension, and lignin, stiff-blocked load-bearing under compression, offer how trees observe decay and external forces and How Trees Grow Old.
Response growth presents itself as trees producing new-growth structural wood against people, pests, place and weather damage and climbing-plant, epiphyte, gravity, ice, rain and rigging overloads.

Response growth presents itself as trees producing new-growth structural wood against people, pests, place and weather damage and climbing-plant, epiphyte, gravity, ice, rain and rigging overloads.
Compartmentalization of decay in trees (CODIT) quarters four defensive walls against such decay as cellulose-questing brown rot, lignin-questing white rot, root-questing structural rot and soft rot. Executive Director Kincaid repeated, before responding to four webinar-attendee questions, the first regarding exposed-wood online images, that environmental-catastrophe, structural-failure, system-failure stresses reveal How Trees Grow Old. He suggests for declining, older trees mulching organically, protecting roots, pruning dieback and supplying micronutrients even as he supports city arborists saving or supplanting senescent trees.
Executive Director Kincaid terminated the webinar How Trees Grow Old after treating conifers, hickories, oaks and slow-growers as longer-lived than deciduous, fast-growing, poplar and willow trees.
