Download or read book Hydrogeochemical Soil Dynamics Relative to Topography for Forested Land Units Undergoing Reclamation in a Post mined Landscape in the Athabasca Oil Sands Region Alberta written by Tristan Gingras-Hill and published by . This book was released on 2017 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural forest soils of the Western Boreal Forest rarely witness near-surface soil flushing events during the growing season due to the forest's excessive evapotranspiration demands and large unsaturated zone storage capacity. This leads to the accumulation of nutrients such as Soluble Reactive Phosphorus (SRP) and Total Inorganic Nitrogen (TIN) within the surface soils, increasing along a low-relief moisture gradient transitioning through upland forests, riparian zones and wetlands, influencing vegetation communities. In the post-mined landscape, decompressed overburden produce topographically elevated hillslopes with cover soils exhibiting poor transmissivity and hydrophobic properties, which are often subject to erosion. Reclamation projects are beginning to develop entire watersheds consisting of engineered wetlands, uplands and hillslopes, varying in elevation, to ensure a hydrologic connectivity that can support resiliency to moisture deficit during periodic stresses. To avoid undesirable interactions between land units, it is important to understand their hydrogeochemical connectivity. This study focuses on the interactions between a recently (i.e. three years) reclaimed low-relief upland and three encompassing hillslopes (aged five to nine-years since reclamation), located within a constructed fen watershed. The objectives were to determine if topographically driven moisture-nutrient gradients were being formed and how this would influence vegetation colonization. No topographically driven moisture-nutrient gradient was detected within the lower-lying constructed upland, attributed to the heterogeneity of the cover soil placement and the lack of preferential flow paths, typically witnessed in newly reclaimed soils. Furthermore, the application of control release fertilizer likely hindered the detection of any topographic influence on ion mobility. Runoffs collectors suggest that fertilizer may lead to off-site movement immediately following application. Results also demonstrated that SRP is likely in excess within this system and susceptible to leaching following overland flow events. However, TIN is potentially a limiting nutrient and while immobilized at the surface, demonstrated greater susceptibility towards vertical flow, especially when groundwater recharge promoting structures are incorporated within the construction of forested land units. Sapling survival within the constructed upland appeared to be influenced by moisture stress over nutrient availability, re-examining the need for fertilizer application when reclaimed soils still lack moisture absorbing properties. The elevated hillslopes also did not demonstrate any topographically driven moisture-nutrient gradient regardless of age since reclamation. The more mature hillslope was expected to demonstrate such a gradient, however the dry growing season likely hindered subsurface interflow downslope. The two younger hillslopes still demonstrated poor transmissivity attributed to their immaturity. TIN contributions towards the constructed upland proved to be minimal, however phosphorus inputs from erosion prone areas are likely to influence SRP availability following phosphate desorption processes within the constructed upland. Although our system demonstrated positive correlations of increased SRP on native species establishment, TIN availability demonstrated increased forb and non-native species colonization. This study demonstrates how current forested upland reclamation practices might influence other land units when re-initiating hydrogeochemical connectivity throughout engineered landscapes. This study also demonstrates how contributions from topographically elevated land units might impact vegetation communities downslope, which is crucial for re-establishing the resiliency of the landscape. Current forest upland and hillslope reclamation practices will likely need to be re-evaluated when considering landscape scale hydrogeochemical connectivity.

Book excerpt: For reclamation to be considered successful, an ecosystem must be self-sustaining and have a recovery trajectory that falls within the range of variability of ecosystem function in natural ecosystems. This study compared the soil nitrogen availability, soil microbial community, and understory vegetation following natural (wildfire) disturbance and anthropogenic (reclamation) disturbance, in the Athabasca Oil Sands Region. Eleven natural (aged 2-131 years) and five reclaimed sites (aged 4-27 years) from upland aspen/ spruce stands were compared. Soil available nitrogen was assessed in-situ with ionic resin capsules and potentially mineralizable nitrogen was determined by anaerobic incubation. Microbial respiration was measured as an indicator of activity, and microbial community fingerprints and biomass were determined using phospholipid fatty acid analysis. The vegetation was characterized by canopy cover, plant functional group, and composition survey at the genus level. No significant difference for nitrate or ammonium availability was observed at the site level; however, there were trends with time and canopy cover. The potentially mineralizable nitrogen trend with time was much higher on the natural sites than the reclaimed sites. Non-metric multi-dimensional scaling ordinations of the soil microbial community and understory vegetation composition revealed that reclaimed and unburned sites had significantly different communities with a low degree of similarity. The burned sites (aged 2-39 years) were more variable and bridged the difference between the reclaimed and mature sites. The microbial community of the oldest reclaimed sites were most similar to naturally disturbed sites. This work shows that young naturally disturbed sites may be a more relevant comparison when evaluating reclamation trajectory than mature stands.

Book excerpt: Underneath the almost 3,500 square kilometres (km2) of boreal forest in the Athabasca formation, the oil sands deposits are close enough to the surface (less than 100 metres deep)2 to be mined.3 Companies from all over the world have been given the green light to surface mine (strip mine) for oil sands in the Athabasca Boreal region of Alberta on the assumption that they can and will fully reclaim [...] This amount is in addition to the removal of an average of 2,000 kg of overburden per barrel of oil to access the bitumen-saturated sand.8,9 The dominant method of oil sands mining is the truck and shovel method. [...] Historically speaking, the term reclamation is commonly used in the context of mined lands in North America and the United Kingdom.48 In Alberta, reclamation is defined simply as the "stabilization, contouring, maintenance, conditioning or reconstruction of the surface of land,"49 which is a very different goal to restoration, which is an intentional activity that initiates or accelerates the reco [...] Here lies the distinction between reclamation and restoration: restoration is far less associated with the utility of the landscape and is guided by ecological principles to promote the recovery of ecological integrity.57 A restored ecosystem contains a characteristic assemblage of the species that occurred in the reference ecosystem. [...] Despite the enormity of disturbances caused by the mining process - the altering of natural hydrological systems, the volumes of earth that are dug up and moved, and the capacious creation of wastes - companies assure Albertans that mitigation of these terrestrial disturbances through reclamation is guaranteed.
