Pre-Harvest Assessments

Pre-Harvest Assessments are completed to determine site specific conditions before harvest plans are developed. This information is used to determine the appropriate Silviculture System. The Silviculture System represents a set of prescriptions for the removal and subsequent renewal and growth of the forest. Spray Lake Sawmills uses a number of silviculture systems.

Harvest Systems

A Harvest System is the means used to cut, limb and forward trees to the point where they can be loaded for hauling. Spray Lake Sawmills uses feller bunchers, stumpside processors and grapple skidders as their primary means for harvesting. Site productivity, environmental considerations and reforestation requirements are the primary determining factors in selecting the best harvest system for a site.

Post Harvest Surveys

Post Harvest Surveys are completed to determine if the initial silviculture prescription determined in the Pre- Harvest Assessment can be achieved due to the site specific conditions present after harvest.

Seedlings

  • Lodgepole pine and white spruce cones are sourced from local forests, suited to harvest site growing conditions. Cones are dried, the seed is stratified and grown in Alberta and Saskatchewan tree nurseries.
  • All of the trees we plant are 100% natural and native to the forests where they are planted.

Site Preparation

  • No chemicals, herbicides or pesticides are used in the forest.
  • During the harvest process, tree tops are retained on site for nutrient cycling. Scarification (mechanical raking) creates favorable seed beds for natural regeneration and ideal planting spots for planted seedlings.
  • Seedling microsites, provide added moisture and shade as well as wind and frost protection.
  • Native herbaceous plants, hardwoods and shrubs also benefit from scarification increasing harvest area biodiversity.
  • Scarification also has added benefits of breaking down fuel continuity enhancing fire prevention and control efforts.

Tree Planting

  • Every June, when soil temperatures and soil moisture are favorable, trees are planted by hand in microsites, to promote reforestation success.
  • Each year, we plant approximately 2 million trees!

Establishment Surveys

  • Establishment surveys are legislated requirements detailed in the Timber Management Regulation.
  • The surveys must be done between 4 to 8 years after harvest.
  • Reforested areas must achieve both a specified stocking level and a minimum level of growth performance.

Performance Surveys

  • Performance surveys are also legislated requirements detailed in the Timber Management Regulation.
  • The surveys must be done between 8 to 14 years after harvest.
  • The same information as an Establishment Survey is collected; however, coniferous trees must meet the Free-to-Grow criteria.
  • A tree is considered Free-to-Grow when it is located at least 2m from any deciduous competitor tree/shrub.
