180 various soils. The estimates in this table are based on measurements and observation of established plantings that have been given adequate care. They can be used as a guide in planning windbreaks and screens. Additional information on planning windbreaks and screens and planting and caring for trees and shrubs can be obtained from local offices of the Natural Resources Conservation Service or the Cooperative Extension Service or from a nursery.
Forestland Paul M. Deizman, district forester, Illinois Department of Conservation, helped prepare this section. Forest once covered nearly 45 percent of the land in the survey area. Little of the pre-settlement forestland has been untouched or properly managed. Presently, McHenry County has 21,000 acres of forest. This acreage represents 5.2 percent of the total land area in the county. About 8,000 additional acres, representing another 2 percent of the total acreage, is considered tree-covered land or brushland. Over the past century new forests have been created only by natural succession of fallow upland and bottom-land areas, by abandonment of lowyielding cropland, and by seeding or planting of seedlings. Only 10 percent of the present forestland is under proper timber management. Areas of grazed forestlands are slowly recovering, but many decades or a full forest generation may be needed before these areas can become productive without management. As demographics change within the county and as time passes, these same forestation realities will continue to be significant. Principal forest cover types in McHenry County include oak-hickory (10,000 acres), maple-beech (7,000 acres), elm-ash-soft maple (3,000 acres), and cottonwood (1,000 acres). Among these principal forest types and other minor cover associations, at least 77 different tree taxa and 89 shrub taxa occur in McHenry County. McHenry County has three sawmills. Although the number of sawmills has been gradually declining, the sawmills in and around the county borders adequately serve the local demands for custom sawing. Today’s hardwood timber markets are globally oriented and allow any owner with quality forest products reasonable access to commercial markets through interested buyers, forest operators, state foresters, and forestry consultants in this part of the midwest. The demand for standing timber from McHenry County remains high. At last count, 59 firms employing nearly 12,000 individuals manufacture or wholesale wood products and paper products in McHenry County. McHenry County has tremendous potential for 181 establishing additional productive forestland. The highly erodible land (HEL) classification includes nearly 37,000 acres that would be well suited to hardwood forest. Forestry in McHenry County is not only potentially profitable but serves to protect and enhance watershed quality, recreation areas, and wildlife habitat. Interest in forest management and establishment in the county is very high. The average forest holding per landowner is 15.5 acres. Even parcels as small as 5 acres can be effectively managed for both timber production and multiresource conservation. Assistance in establishing, improving, or managing forestland is available from foresters or specialists in natural resources. Table 11 can help woodland owners or forest managers plan the use of soils for wood crops. Only those soils suitable for wood crops are listed. The table lists the ordination symbol for each soil. Soils assigned the same ordination symbol require the same general management and have about the same potential productivity. The first part of the ordination symbol, a number, indicates the potential productivity of the soils for an indicator tree species. The number indicates the volume, in cubic meters per hectare per year, which the indicator species can produce in a pure stand under natural conditions. The number 1 indicates low potential productivity; 2 or 3, moderate; 4 or 5, moderately high; 6 to 8, high; 9 to 11, very high; and 12 to 39, extremely high. The second part of the symbol, a letter, indicates the major kind of soil limitation. The letter R indicates steep slopes; X, stoniness or rockiness; W, excess water in or on the soil; T, toxic substances in the soil; D, restricted rooting depth; C, clay in the upper part of the soil; S, sandy texture; F, a high content of rock fragments in the soil; L, low strength; and N, snowpack. The letter A indicates that limitations or restrictions are insignificant. If a soil has more than one limitation, the priority is as follows: R, X, W, T, D, C, S, F, L, and N. In table 11, slight, moderate, and severe indicate the degree of the major soil limitations to be considered in management. Erosion hazard is the probability that damage will
