ALPAC-01-006
Project Name:
White Spruce Understory Protection
Company Name:
Alberta-Pacific Forest
Projected Cost:
$222,067.00

This Project was the forerunner of Project No. ALPAC- 01-07, which to date has produced 1998 & 1999 Progress Reports - entitled, "Alternative Silviculture Systems for Ecosystem Based Management of Boreal Mixedwoods." The study examines aspen dominated stands with white spruce understories and evaluates several harvesting methods including the economical, operational and regeneration implications of a two-pass shelterwood system that removes the aspen overstory while protecting the spruce understory.

ALPAC-01-007
Project Name:
White Spruce Understory Protection
Company Name:
Alberta-Pacific Forest
Projected Cost:
$828,653.02

The primary objectives of the original Project that commenced in 1995 were as follows:

  • investigate a two-pass harvest system designed to remove aspen pulpwood with minimal damage to well distributed white spruce understory;
  • investigate the amount of white spruce seed and seedling ingress that results from leaving various densities of residual white spruce in a predominantly aspen clearcut; and
  • investigate the feasibility of creating a mixedwood stand by underplanting white spruce into a mid - rotation aspen stand.
  • Project planning, plot installations, timber harvesting, data collection, data analyses, determination of findings, and report writing took place over the period 1995 to 2005, inclusive.

    Final Project results are contained in two separate reports, namely -
  • "Final Report: Alternative Silviculture Systems for Ecosystem Based Management of Boreal Mixedwood Stands", dated June 8, 2004; and
  • "Understory Protection and Underplanting Trials Technical Report", prepared by Gitte Grover of Alberta - Pacific Forest Industries, and dated October 7th, 2005.

ALPAC-01-009
Project Name:
White Spruce Understory Dynamics
Company Name:
Alberta-Pacific Forest
Projected Cost:
$54,629.00

The primary purpose of this Project was to explore the dynamics of white spruce recruitment in the understory of forested stands as an aid to enhance mixedwood management.

The objectives of this Project included characterizing attributes of stands with and without conifer understories, spatial linking conifer understories to seed sources, quantifying potential relationships between overstory, understory and seed source attributes, and exploring the potential for developing predictive algorithms for forecasting conifer understories.

ALPAC-01-010
Project Name:
Role of Photoinhibition of Photosynthesis and Soil Water in the Initial Establishment of Clearcut-Planted White Spruce Seedlings
Company Name:
Alberta-Pacific Forest
Projected Cost:
$56,730.00

The primary purpose of this Project was to specifically address how shade and soil moisture impacts spruce photosynthetic performance and growth in the first two years after planting.

Objectives included documenting the seasonality and degree of photoinhibition in newly planted white spruce seedlings, assessing the impact of photoinhibition on spruce growth, and assessing the interaction of soil moisture and photoinhibitory light on white spruce photosynthesis and growth.

This Study was carried out over the summer field seasons of 1999 and 2000. Its results are contained in a May 2001 twenty-six page report entitled, "Role of Photoinhibition of Photosynthesis and Soil Water in the Initial Establishment of Clearcut-Planted White Spruce Seedlings" authored by Messrs. Greenway and Man.

ALPAC-01-011
Project Name:
Resource Utilization of White Spruce
Company Name:
Alberta-Pacific Forest
Projected Cost:
$183,995.00

Principal objectives for this Project included determining if there is a direct nutritional interaction between aspen and white spruce through mycorrhizae connection; and ascertaining whether aspen and white spruce have different resource utilization regimes when grown in different resource conditions & compositional mixes.

Field activities, data collection & analysis, and report writing for these two studies took place over the time period of January 1999 to December 2004.

Final Project results are contained in two separate reports -

* "Role of Mycorrhizae in Aspen - White Spruce Nutritional Interaction", prepared by Ken J. Greenway & Rongzhou Man of the Alberta Research Council, and dated April 2001; and
* "Resource Use by Aspen and White Spruce - Implications for Climate Change and Moisture Stress on Tree Growth and Development", prepared by Ed J. Korpela of the Alberta Research Council, and dated December 2004.

ALPAC-01-012
Project Name:
Re-establishment of CFS Research Sites
Company Name:
Alberta-Pacific Forest
Projected Cost:
$62,375.00

The purpose of this Project was to evaluate, re-establish and re-measure long-term research trials originally established by the CFS in the 1950's and 1960's to investigate natural regeneration in shelterwood and seed tree retention systems.

Project objectives include demonstrating actual long-term conifer and deciduous survival growth and yield response to a variety of mixedwood harvesting, silviculture and site preparation techniques.

Historical research trials were prescreened with the acceptance of five appropriate trials for re-measurement, of which four were re-established during the 1999 field season. The results of this Project are captured in a May 2000 report entitled "Re- measurement of Canadian Forest Service Mixedwood Management Research Sites: Athabasca to Slave Lake Corridor" authored by MacIsaac, Lux and Sidders of the Canadian Forest Service.

Project Name:
Rates of Natural Reforestation on Wellsite and Seismic Line Disturbances in Alberta Boreal Forests
Company Name:
Alberta-Pacific Forest
Projected Cost:
$91,286.42

The primary purpose of this Study was to investigate the rates of natural reforestation on energy sector disturbances and evaluate the impacts of those rates on the sustained yield of forest resources in Alberta's Boreal Forest.

Project objectives included determining the presence and rates of natural vegetation regeneration on seismic lines and wellsites; comparsion of these rates with reforestation on forest cutblocks, burns, & new disturbances; and an evaluation of these variable reforestation rates on the sustained yield of timber volumes.

The results of this research arepublished in an eighteen page report entitled "Natural Reforestation on Seismic Lines and Wellsites in Comparison to Natural Burns or Logged Sites" and dated December 21, 2001.

ALPAC-01-014
Project Name:
Post - Disturbance Stand Dynamics
Company Name:
Alberta-Pacific Forest
Projected Cost:
$47,084.28

The primary objective of this Project was to determine the rate and pattern of blowdown of residual aspen trees and snags, approximately 5 years post - harvest and post - burn, by revisiting sites originally sampled in 1996 and 1997.

During the summer season of the year 2000, sixteen structured cutblocks were sampled ranging in size from 7.9 ha to 51.7 ha for a total sampling area of 384 hectares. Fifteen sites [in three stands] and nine sites [in two stands] were sampled in high intensity and low intensity wildfires, respectively with each site measuring 1 ha (100m x 100 m).

Final study results are contained in a thirty-four page document entitled "Post Disturbance Stand Dynamics: Falldown of Residual Trees and Snags Following Harvest and Wildfire", prepared by the Alberta Research Council [Stephen Hanus, Susan Crites, and Shawn Wasel], and dated March 30. 2001.
