Name(s): Creator (cre): Kellaway, Edward James, Thesis advisor (ths): Watmough, Shaun A., Degree committee member (dgc): Eimers, M. Catherine, Degree committee member (dgc): Basiliko, Nathan, Degree granting institution (dgg): Trent University
Abstract: <p>Soil and tree chemistry were measured across 15 limed sites that were established 14 to 37 years ago within the Sudbury barrens in Ontario, along with two unlimed pre-treatment condition reference sites and an unlimed remnant pine forest. Soil pH and base cation (calcium (Ca), magnesium (Mg), and potassium (K)) concentrations were elevated in surface organic [FH] horizons up to 37-years… more

Name(s): Creator (cre): Deighton, Holly, Thesis advisor (ths): Watmough, Shaun A, Degree committee member (dgc): Basiliko, Nathan, Degree committee member (dgc): Hazlett, Paul W, Degree granting institution (dgg): Trent University
Abstract: <p>One possible solution to acidification and losses of base cations in central Ontario forest soils may be the application of wood ash. Wood ash is generally high in pH and contains large amounts of calcium (Ca) and other nutrients essential for ecosystem health, however it also contains trace metals. Understanding the chemistry of soils following ash application to forests is crucial for… more

Patterns of Vegetation Succession on Nickel-Copper Mine Tailings near Sudbury, Ontario

Member of: Trent University Graduate Thesis Collection
Name(s): Thesis advisor (ths): Watmough, Shaun A., Degree committee member (dgc): Basiliko, Nathan, Degree committee member (dgc): Hutchinson, Tom C., Degree granting institution (dgg): Trent University
Abstract: <p>Natural establishment of vegetation on mine tailings is generally limited. Understanding the processes leading to vegetation germination and the survival mechanisms that vegetation species employ in these harsh environments is critical to future remediation efforts. As metalliferous mine tailings are generally nutrient-poor, high in harmful metals, and acidic, vegetation species require… more
