To explain:
The tree dies slowly (weekly) or quickly. As if a complete ring of bark is removed around a tree trunk (a process is called girdling).
Introduction:
The complete removal of a layer of bark that consist cork cambium or phloem from a branch of a tree or a woody plant is termed as girdling. It is also termed as ring-barking.
In trees and woody plants, growth and development occur simultaneously as primary and secondary. The primary growth occurs in stems and roots to add leaves and stems in the younger regions of a plant, while the secondary growth increases the thickness of stems and roots in the older regions.
The vascular cambium and cork cambium is tissues of secondary growth. The cork cambium plays a major role in the production of a tough, thick covering of waxy cells which protects the stem.
The vascular tissue system comprises two primary components: xylem and phloem. These components function together for the growth, development and photosynthesis in plants.

If you add heterotrophic respiration and autotrophic respiration together and then subtract that value from gross primary productivity, then you have a more refined estimate of ecosystem carbon storage than NEE.
