Girdling

 

in trees and grapevines, a notched ring or the removal of a ring of bark (3–5 mm wide) right up to the wood. The trunk or the skeletal branches of apple and pear trees are girdled. In grapevines the main trunk, perennial branches, or annual shoots are girdled. Girdling is performed in early spring. The wound is covered with grafting wax or opaque paper. As a result of girdling, fruit trees bear fruit earlier and are more productive. In grapevines the conditions for setting the berries is improved and the size and sugar content is increased; the grapes also ripen quicker.

While we examined and measured the pines in late winter/early spring, we observed a great amount of fresh girdling activity, leading us to hypothesize that pine bark was providing a source of nutrition at a time of year when rodent density was relatively high and the quality of their principal food, monocots, was likely to be poor.
Information collected at the sub-cell level was used for statistical analysis of the habitat and girdling damage in the four sub-cells surrounding each trap station.

These included Spearman's rank correlations for interval-interval or interval-ordinal variable comparisons such as the girdling index to pellet group counts, and the girdling index to aspect (an ordinal variable with 8 levels).
Mortality was positively correlated with the girdling index (y = 49.
In 1995, CER for the girdled treatment was significantly lower (40-60%) for all three cultivars for at least 20 d after girdling (Fig.
Defoliation of girdled plants increased CER only in the experiments where girdling reduced CER.
Girdling refers to the process of peeling off the bark of a tree trunk to prevent it from sharing nutrients.
Last year, Reyes led a crusade to save 770 trees which sustained girdling injuries along the MNR expansion area in eastern Pangasinan towns.
During a March session of the Pangasinan provincial board, a DENR official said girdling, or the process of peeling off a section of a tree's trunk to prevent nutrients from reaching its branches, violated the provisions of the treecutting permit.
We did not expect the girdling to happen," said Leduina Co, provincial environment and natural resources officer.
