Winter tree planting in wetlands

A consortium consisting of Alberta Environment and Parks, industry, and restoration experts completed a tamarack planting trial this past winter. The objective of the trial was to explore the possibility of planting tamarack seedlings during frozen conditions. The concept was inspired by previous research on winter planting black spruce with results of a 94% survival rate. The black spruce trial led to the technique being applied on a number of caribou restoration projects that involved restoring native vegetation on linear disturbances throughout North Eastern Alberta.
Why plant in the winter? Most wetland reclamation takes place during the winter months due to poor or no summer ground access. Planting during the winter removes the expense of flying seedlings and planters in during the summer. Cost savings to the client can range from $2.00 to $3.00 per seedling.
Both winter trials took place in wetlands at the Evergreen Centre for Resource Excellence and Innovation in Grande Prairie, AB. The 2016 trial demonstrated it is possible to successfully plant tamarack in the winter. For more information please contact Dave Larsen with Global Restoration Corp.

Reclaiming placer mining settling ponds

Placer mining, the mining of stream bed deposits for gold, is an important economic driver of Yukon’s economy. Settling ponds are used as part of the placer gold mining process to separate out sediment, and are often reclaimed to open water and marsh wetlands once operations are complete. While there is no specific end goal for reclaimed ponds and no established methods for evaluating reclamation success, these ponds are often used by waterfowl for breeding and migration. To better understand what makes a reclaimed settling pond attractive from a breeding waterfowl perspective, Ducks Unlimited Canada (DUC) has partnered with the Klondike Placer Miners’ Association and the Yukon Government to examine whether characteristics of existing ponds (e.g., size, depth, substrate, etc.) are correlated with waterfowl breeding pair and brood use. Identifying these characteristics will help define best management practices to maximize attractiveness and productivity of future reclaimed settling ponds to breeding waterfowl. Field work, including waterfowl surveys, will take place during spring and summer of 2017 in the Indian River valley near Dawson, Yukon. Final results are expected in early 2018. This project was undertaken with the financial support of the Government of Canada through the federal Department of Environment and Climate Change.

The Forestry Chronicle Special Edition


The Forestry Chronicle is the official journal of the Canadian Institute of Forestry. Since 1925 it has provided information about professional and scientific management of forests and forest resources as well as helped facilitate communication among forest practitioners in Canada and around the world. A special issue of The Forestry Chronicle, released in January 2016, presents long-term watershed research studies to assist in making informed land-use and management decisions. Early long-term hydrologic studies have been important for evaluating and improving forest management. For example, the Tri Creeks Experimental study demonstrated that ensuring best management practices are followed is critical in reducing sedimentation. Studies reviewed in this special issue include: Al-Pac Catchment Experiment, Bear Creek Watershed Investigation, Forest Watershed and Riparian Disturbance Project (FORWARD) and many more.

Peatlands play an important role in removing COfrom the atmosphere.

Peat is a thick spongy organic soil made of dead decomposing moss. The cold northern climate slows down decomposition resulting in peat soils that can range from 40 cm to 5 m in depth. In Canada's western boreal forest, peatlands account for 90% of all wetlands and approximately 60% of all organic carbon in Canada is stored as peat (Vitt et al. 2001).

Ducks Unlimited Canada has been a part of various carbon mapping initiatives, including one to estimate average carbon mass for each 19 wetland classes in their Enhanced Wetland Classification (EWC).
