This should be done before forest management or establishment activities commence. Contact your local Ontario Ministry of Natural Resources field office for assistance in forest management decisions. (5) How toApply the Suitability Ratings Table Before the suitability ratings table can be applied, one must firstbe familiar withthe mapunit symbols which identify the type of land area or areas represented by map delineations. Recognition of the components of each symbol is necessary, since the type of land areas upon which the ratings are based account for at least one component of each symbol . A map unit symbol may contain one or two components representing types ofland areas . If it contains one such component, only one set of suitability ratings for various tree species apply. If itcontainstwo suchcomponents, however, two sets of suitability ratings apply, one for each type of land area . When two land area components are shown, the first one is dominant in occurrence while the second occurs in significant proportions . Refer to the section ofthe report, "Definitions ofTerms and Components Associated with the Soil Maps and Legend," for more detailed explanations . Once the types of land areas which are shown in a map unit symbol have been determined, suitability ratings by species for those areas can be found in Table 19 with one excep tion . Land areas represented by a soil landscape unit and an identified soil phase or phases constitute a separate land entity for which additional ratings by species are given. Four types of soil phases may be shown in a map unit symbol in conjunction with a soil landscape unit . These are : S- Shallow Phase - bedrock occurs at 50 to 100 cm depth O-OrganicPhase -- 15 to 40 cm of organic material at the surface C-Coarse Phase - 15 to 40 cm of surface material significantly coarser textured than the underlying material F-Fine Phase - 15 to 40 cm of surface material significantly finer textured than the underlying material Other symbol components such as slope class or stoniness class are not required to determine suitability ratings in the table. These components were not considered in the interpre tive process, but as discussed inthe section "Limitationsto the Rating System," may be severe enough to warrant modification ofthe givenratings for each tree species . The following procedure should be followed when determining the suitability ratings by species for the land area component or components shown in a map symbol : 1 . Study the "Explanation ofthe Map Unit Symbols" shown on the border of each soil map. Also refer to the section of the report "Definitions of Terms and Components Associated with the Soil Maps and Legend ." These provide explanations of the various types of map unit symbols and their respective components . 2 . Locate the symbol on the soil map for the area you are concerned with . 3 . Identify the land area component or components . One or two types ofland areas may be portrayed in amap unitsymbol, which may be a soil landscape, land type, or miscellaneous land unit as defined in the map legend . 4 . Identify any soil phases which are shown and the type of land area or areas they are associated with . Only soil landscapeunits have associated soil phases . 5 . Proceed to Table 19 . Suitability ratings by species are given for all types of land areas without soil phases, and also for those with soil phases . 6 . In the Land Area column, find each identified land area with or without associated soil phases . Listed horizontally beside each area are suitability ratings for eight commonly planted forest tree species in eastern Ontario . (6) Examples of Some Rating Determinations (a) For a map symbol of C3 2 C3 is the land area component of the symbol for which suitability ratings are given . From Table 19, locate C3 in the land area column . Listed horizontally beside C3 are the suitability ratings for eight forest tree species, i .e. C3 is rated PU (Poor to Unsuitable) for White Spruce (Sw) . For a map symbol of F1-Gl R2.3-S1 .2 F1 and GI are the land area components ofthe symbol for which separate suitability ratings aregiven . From Table 19, F1 is rated U (Unsuitable) for White Pine (Pw), and G 1 is rated G (Good) forthe same species . From the "Explanations ofthe Map Unit Symbols" on the soil map, F 1 is the dominantly occurring land area, and G 1 occurs in significant proportions. Thus, the delineated area is dominantly Unsuitable for White Pine, with a lesser but significant proportion being Good for the same species .
