Object & Deliverables


To gather information on sucker development on specific sites as well as give a description of trends in aspen mortality over time. The first phase was aimed at gathering and summarizing the data on aspen mortality in the literature. 22 independent studies with applicable data were found and graphed to depict relative aspen mortality. The second phase added study sites that addressed specific questions about aspen juvenile stem dynamics under various conditions. Five different areas were selected (Drayton Valley, Grand Prairie, Conklin, Wabasca and Slave Lake) representing different soil and moisture regimes resulting in various sucker densities. Each region had six study blocks. Within each block 12 plots were placed in areas densely or sparsely populated with suckers. The methodology resulted in large variances in densities of suckers. The intention is that plots would be remeasured and assessed for viability over a number of years.

Final Report

The project was closed after 2000 but was continued under ALPAC-01-023. The final report for this project was submitted by Ken Greenway and Amar Varma of Alberta Research Council and entitled, “Juvenile Aspen Mortality – Annual Progress Report – Fiscal Year 2000-2001”.
