Abiotic and biotic factors used to assess decline risk in red pine (Pinus resinosa Ait.) plantations

Abstract: This study was conducted to assess causes of unprecedented rates of mortality in maturing, commercial-sized red pine (Pinus resinosa Ait.) plantations in southern Ontario, Canada. Concentrated and diffuse mortality as well as windthrow of living trees were observed in many plantations, while others seemed disease-free. Nine sites exhibiting recent mortality (diseased) plus three not exhibiting disease (healthy) were selected. In sample plots at each site, abiotic site factors, host characteristics, and insect … Show more

“…Forest growth, productivity, and tree health are a function of site productivity and soil conditions (e.g., McLaughlin et al, 2011) (Table 6). Tree health is impacted by factors that affect soil fertility and the availability of essential plant nutrients, especially in southern pines (Fox et al, 2007).…”

“…Armillaria root disease is caused by an assortment of Armillaria species and resultantly, impacts a broad range of host species (Raabe, 1962;Baumgartner et al, 2011). Our focus here is on Armillaria ostoyae, a highly virulent pathogenic species that causes extensive mortality in pine plantations (Filip et al, 2010;McLaughlin et al, 2011;Lockman and Kearns, 2016). Armillaria ostoyae can rapidly spread within conifer plantations by means of root-to-root contact and via soil rhizomorph production (Toussoun et al, 1970;Myren et al, 1994).…”
