Trees and Paper – Part 2: An Overview of Environmental Considerations
- The management plan covers an 80-year planning horizon and is divided into five-year submission windows which divides the harvest over time.
- One of the key planning tools is a computerized GIS mapping system (Geographical Information System) that stores vast amounts of data on environmental, economic and social elements of the managed forest area. The system is used for predictive modelling and is regularly updated based on aerial recognition and field observations by foresters.
- Many forest areas are excluded from harvesting including protected or conservation areas, deer wintering grounds, buffer zones near watercourses and wetlands, sensitive wildlife habitat.
- By law, large watercourses have a buffer zone of 60-100 meters and all other flowing water, including wetland at least 30 meters.
- Harvesting road areas and road construction are part of the plan. Bridge construction requires approval and is closely monitored to minimize impacts to the aquatic ecosystem. The type of bridge installed depends on the size of the watercourse drainage area.
Step 2 - Cruising
- Each block of a management plan is cruised by foresters who complete a field assessment using geo-recorders (data recorders with GPS tagging). The data is then uploaded to the GIS system to determine the real harvest area which is usually smaller in size than what was originally planned, due to environmental and other conditions.
- Recorded data includes tree species, number of trees per hectare, tree age and condition, watercourses, raptor nests, den sites (ex: bobcat, bears, etc.), and many more indicators.
- Different forest areas are treated differently based on tree age and species structure. There can be over 12 different types of harvest treatment specifications, including shelterwood, selection cut, strip cut, commercial thinning and many more.
- Certified loggers are used to conduct harvesting. They are trained in forest certification, such as the Sustainable Forestry Initiative (SFI) and Forest Stewardship Council (FSC) requirements, and also trained by the company to respect environmental guidelines and regulations which are specified in the company’s ISO 14001 environmental management system.
- In many cases, state-of-the-art “harvesters” with on-board GPS are used to conduct harvesting based on uploaded GIS data from the forest management plan.
- The harvested trees are used for many purposes including lumber for construction, pulp for papermaking, and in some cases, viscose pulp for the textile industry. In many cases 25 percent or less of the harvested trees are used for pulp, and even less goes to printing and writing paper.
- Much of the wood fiber used in pulp production for paper-making is coming from sawmill chips, a by-product of sawmills that manufacture lumber for construction.
