A number of significant changes to soil conservation requirements have been introduced over the years. Before any soil conservation survey is undertaken, the first step is to determine what soil conservation requirements were specified and what definitions apply. Each soil conservation survey must be based on the

This guidebook has been prepared to help forest resource managers plan, prescribe, and implement sound forest practices that comply with the Forest Practices Code. Guidebooks are one of the four components of the Forest Practices Code. The others are the Forest Practices Code of British Columbia Act, the regulations, and the standards. The Forest P...
The objectives of soil conservation under the Forest Practices Code (Code) are: To limit the extent of soil disturbance, caused by harvesting and silviculture activities that negatively affect the physical, chemical, and biological properties of the soil. To conduct forest practices in a manner that addresses the inherent sensitivity of a site to s...
To facilitate forest management, part of the forest land base is permanently occupied by roads and other structures that provide access to the forest. Minimizing the amount of productive forest land occupied by these structures is an important objective of forest management. Permanent access structures include on-block roads, landings, gravel pits,...
The proportion of the total area under the prescription (gross cutblock area) to be occupied by permanent access structures should be determined on a site-specific basis. Factors such as soil type, parent material, topography, stand type, silviculture system, harvest methods, equipment standards, management objectives, long-term access requirements...
Engineering and design specifications can be used to estimate and rationalize the area that will be occupied by the permanent access structures. When estimating the area that will be occupied by permanent access structures the width of the structures to be used will depend on what portion of the fill slope will be available for growing a future cro...
When estimating PAS occupancy for prescription purposes or for compliance assessments, the fill slope growing medium should be evaluated to determine whether or not the fill slope should be included in the road width estimate. If fill slopes are to be part of the NAR, it should be reasonable to expect that seedlings will grow on these areas at a co...
Those on-block access structures that do not satisfy the criteria for being classified as permanent access structures are considered temporary. Temporary access structures are required only for a limited period during a specific forest management phase. The area they occupy is part of the NAR, and must be suitable for rehabilitation to enable the e...
The determination of whether an access structure should be classed as permanent or temporary is often contingent on: a) whether the structure is suitable for rehabilitation treatments, given the type of material through or with which it is constructed, and b) the period of time for which the structure will be required for forest management activiti...
G. Ensure that the maximum proportion of the NAR that may be occupied by soil disturbance is specified in the silviculture prescription. An objective of placing limits on the amount of soil disturbance allowed within the NAR is to ensure that site productivity is maintained and that impacts to other resource values are prevented or mitigated. Harve...
Soil disturbances of the types and dimensions described in the regulations should not occupy more than 5% of any portion of the NAR for the area under a silviculture prescription. The actual proportion of the NAR that may be occupied by soil disturbance must be determined for each site and specified in the silviculture prescription. Where it can be...
Before standards units for silviculture prescriptions are delineated, site and soil data must be collected to characterize variability in site sensitivity. The subsequent evaluation of mineral soil sensitivity involves working through hazard assessment keys for soil compaction and puddling, soil displacement, and soil erosion. All three soil distur...
The district manager may consider approving a greater amount of soil disturbance than the recommended maximum allowable limits if: that disturbance is unavoidable in the process of achieving other significant management objectives; and the proposed activities (responsible for the greater soil disturbance) will not cause or increase the risk of dama...
H. The maximum limit for soil disturbance in the NAR can be temporarily exceeded to construct temporary access structures, as long as: the maximum extent of this additional disturbance is specified in the silviculture prescription; the temporary access structures are identified in the prescription; and the prescription specifies the maximum time re...
Soil disturbance has the least potential to reduce soil productivity if it is dispersed. Harvesting or silviculture operations should be planned and conducted to avoid creating areas of concentrated soil disturbance in localized areas. Generally, the amount of soil disturbance within any contiguous area greater than 1 ha (i.e., away from roads, lan...
I. Ensure that critical site conditions (including sensitive soils) that affect the timing of operations are described in the silviculture prescription, along with a description of how these conditions affect such timing. All sites can experience excessive soil disturbance when soils are wet enough, and therefore due diligence is required to avoid ...
Roadside work areas within the NAR are located adjacent to haul roads and are used during roadside harvesting operations for such activities as decking, processing, loading, and debris piling and disposal. Roadside work areas can be subject to concentrated and high levels of soil disturbance compared to other areas within the NAR. The width of a ro...
L. If mechanized stand tending treatments are proposed, ensure that the maximum proportion of each treatment unit that can be occupied by soil disturbance (caused by the treatments) is specified in the stand management prescription. Determining the level of allowable soil disturbance requires first assessing the disturbance already created by previ...
Note: Amendments to the Act and regulations may occur periodically and could result in changes to section numbers listed in the table. In the event of any changes an updated appendix will be made available on the Ministry of Forests guidebook publication website under the heading of “Soil Conservation Guidebook – updates.”

CLI maps published in Ontario present information at various levels of detail, depending on the scale of the soil survey maps they were derived from (Table 1). Published provincial Soil Survey Reports can be found at Soil Surveys for Ontario. Small scale maps such as 1:250,000 cannot show areas smaller than 250 hectares in size.
Jan 9, 2022 · Geotechnical surveys, also known as soil reports or soil investigations, should be the first step in any construction project. Your local building code will likely require you to have a current soil report when applying for permits. The report will also contain valuable information for structural engineers, architects, and contractors.

Complete the soil survey according to generally accepted soil survey procedures and base it on an adequate density and distribution of soil profile and landscape inspections. A general guideline is one ground inspection per 2 cm 2 on the final map (Mapping Systems Working Group, 1981). At a scale of 1:10,000, this is one inspection per 2 ...
