Changes in peatland plant community composition and stand structure due to road induced flooding and desiccationDownload
Roads built through peatlands with horizontal water flow can to act as dams that affect local hydrology and thus vegetation composition and structure. On the ‘upstream’ side of roads, soils can become waterlogged causing either increased tree mortality, or stunted tree growth; conversely, the...
Question: Can a wet meadow plant community be established on abandoned peatlands through broadcast plant diaspore spreading in western Canada? Does fertilization impact the development and establishment of the wet meadow? Location: Evansburg, Alberta, Canada Methods: Wet meadow vascular and...
Factors influencing size inequality in peatland black spruce and tamarack: Evidence from post-drainage release growthDownload
1 We used tree ring analysis to determine stem radius and thus examine size variation over time in two even-aged (approximately 40-year-old) mixed populations of black spruce and tamarack established on peatlands in a boreal forest. We also followed the response of one of these populations to...
The Boreal Plains Ecozone is characterized by a moisture deficit climate, as regional precipitation is less than potential evapotranspiration. Perched peatlands situated 20 m above regional groundwater have been identified as common features across the landscape in the Utikuma Region Study Area...
Within the Boreal Plains of north-central Alberta, catchments situated within low permeability glacial terrain are composed of a mosaic of landscape units including ponds, peatlands, and upland aspen forest ecosystems within a sub-humid climatic zone where water deficit conditions are frequent. ...
Influence of wildfire and permafrost thaw on dissolved organic carbon (DOC) in northern peatlands; implications for lability and downstream transportDownload
Peatlands in Canada’s western boreal forest are a major source of dissolved organic carbon (DOC) to downstream ecosystems, where DOC regulates carbon cycling, and can affect ecosystem productivity and habitat quality. Subarctic ecosystems are becoming increasingly vulnerable to the effects of...
Project Report 2001-30
The overall objective of this study was to measure the major nitrogen pools and fluxes in nutrient- and peat-rich, vegetated marshes and fens surrounding shallow ponds in the Western Boreal Plain (WBP) of Canada. Within the same peatland-pond complex, marshes and fens did not differ from each...
Present and potential effects of anthropogenic activities on waters associated with peatlands in AlbertaDownload
A literature review and problem analysis of the present and potential effects of human activities in peatlands on the quality and quantity of associated waters is presented in this report. The specific objectives were to describe: 1. The present state of knowledge about waters associated with...
Re-establishment of hummock topography promotes tree regeneration on highly disturbed moderate-rich fens
Re-establishment of hummock topography promotes tree regeneration on highly disturbed moderate-rich fensDownload
Winter exploration of oil sands deposits underlying wooded fens mostly eliminates the hummock-hollow topography on drilling pads and the ice roads leading to them, after their abandonment in spring. Recovery of black spruce (Picea mariana (P. Mill.) B.S.P.) and tamarack (Larix laricina (Du Roi)...
