“…Mistletoes are, therefore, linked to tree damage and tree decline in plantations, orchards, ornamental trees and natural forests and woodlands around the world (Hawksworth, 1983), leading to study on the control of mistletoe (Minko and Fagg, 1989;Kelly et al, 1997). Before control of mistletoe is carried out, however, the links between mistletoe proliferations and tree decline are worth investigating because: (a) high mistletoe abundances are often symptomatic of larger landscape changes (Reid and Yan, 2000); and (b) mistletoes are keystone resources for biodiversity (Watson, 2001).…”
