FOREWORD This report presents the principal findings of the second forest inventory of State and private lands in western Montana (fig. 1). Data collection began in January 1977 and was completed in December 1978. This report does not note changes or trends since the first inventory of Montana. These items will be included in a State Analytical Report to be published in the near future. The authors gratefully acknowledge the cooperation of the USDA Forest Service, Region 1. Appreciation is also expressed for the cooperation of other public agencies and private landowners in providing information and access to the sample locations. SUMMARY The 16 western Montana counties contain 3.7 million acres of commercial timberland in State and private ownership. These acres support 5.9 billion cubic feet of growing stock and more than 21.1 billion board feet of sawtimber. In 1976, the inventory increased nearly 130 million cubic feet after deducting 28.7 million cubic feet of mortality and some 125.6 million cubic feet of removals. Additional information on total land area, commercial timberland area, timber inventory, growth, and mortality data based on USDA Forest Service Resources Evaluation standards are presented.

National Park Service 2.5% Indian Trust lands 2.4% Figure 2. — Percent of total land area in western Montana by ownership, 1977 (shaded area represents sampled land). Forest Industry 8.5% • Private ownership accounts for 3.1 million acres, 84 percent of the commercial timberland. • Douglas-fir is the predominant forest type on nearly half of the commercial timberland area. Lodgepole pine and ponderosa pine forest types together occupy about 30 percent of the commercial timberland. • One-half the commercial timberland is in the SO- to 84-cubic foot productivity class. • On the average, the commercial timberland is currently producing only about half its annual potential of 70 cubic feet/acre. • About 30 percent of the commercial timberland is in old-growth stands. • Stands that are fully stocked occupy about 30 percent of the commercial timberland. • Some 46 percent of the commercial timberland is contained in only 3 of the 16 western Montana counties, namely Missoula, Flathead, and Lincoln. Inventory • Growing stock volume amounts to 5.9 billion cubic feet and sawtimber volume totals 21.2 billion board feet.^ • An additional 395 million cubic feet of sound wood volume is contained in rough, rotten, and salvable dead trees. • The most dominant single species — Douglas-fir (PseudotsuRa menziesii [Mirb.] Franco) — constitutes 2.2 billion cubic feet of growing stock and some 8 billion board feet of sawtimber. • Forest industry controls 44 percent of the total growing stock and 46 percent ot tne sawtimber volume. • Nearly 70 percent of the trees over 5.0 inches d.b.h. are poletimber size. • But, nearly three-quarters of the growing stock volume is contained in sawtimber stands. • Two-thirds of the growing stock volume is contained in stands dominated by either Douglas- fir or lodgepole pine. • Flathead and Missoula counties combined account for more than one-third of the growing stock and sawtimber volume. Components of Change • Net annual growth amounted to 129.9 million cubic feet of growing stock and 461.6 million board feet of sawtimber. • The annual mortality of 28.7 million cubic feet offsets 18 percent of total annual growth of growing stock. • Mortality reduced the annual sawtimber increment by 89.7 million board feet--16 percent. • Total removals from growing stock equaled 125.6 million cubic feet. This represents 2.1 percent of the standing inventory and 96.7 percent of the net annual growth. • Removals from sawtimber amounted to 804.9 million board feet or 3.8 percent of standing inventory and 174.4 percent of net annual growth. HOW THE INVENTORY WAS CONDUCTED The inventory was designed to provide reliable statistics primarily at the State and study-area levels. Procedures were as follows: 1. Initial area estimates were based on the classification of 84,795 sample points systematically placed on the latest resource aerial photography available. The sample points were summarized and grouped into strata for subsequent field sampling. The photo points, adjusted to meet known land areas, were used to compute area expansion factors for the field samples. 2. Land classification and estimates of timber characteristics and volume were based on observations and measurements recorded at 2,512 ground sample locations. Sample trees were selected using a 10-point cluster that includes fixed plots (1/300 acre) for trees less than 5.0 inches diameter at breast height (d.b.h.) and variable plots (40 basal area factor) for trees 5.0 inches d.b.h. or larger. 'in this report all reference to sawtimber volume is in International 1/4-inch rule. 3. For most species, volume and defect were computed using Kemp's equations. 4. All photo and field data were sent to Ogden, Utah, for processing. Final estimates were based on computer generated statistical summaries of the data. DATA RELIABILITY Individual cells within tables should be used with caution. Some are based on very small sample sizes, and so may result in a high standard error. The standard error percents shown in tables 1 and 2 were calculated at the 67 percent confidence level.

Land Use Classes Forest land. --Land at least 10.0 percent stocked by forest trees of any size, or formerly having had such tree cover, and not currently developed for nonforest use. Commercial timberland. --Forest land producing or capable of producing crops of industrial wood and not withdrawn from timber utilization. (Areas qualifying have the capability of producing in excess of 20 cubic feet per acre per year of industrial wood in natural stands. Currently inaccessible and inoperable areas are included.) Productive-reserved forest land. --Forest land sufficiently productive to qualify as commercial timberland, but withdrawn from timber utilization through statute, administrative designation, or exclusive use for Christmas tree production. Other forest land. --Forest land incapable of producing 20 cubic feet per acre per year of industrial wood in natural stands because of adverse site conditions; includes both reserved and nonreserved forest land. Nonforest land. — Land that has never supported forests and lands formerly forested where use for timber management is precluded by development for other uses.

Bureau of Land Management lands. — Federal lands administered by the Bureau of Land Management . Miscellaneous Federal lands. --Federal lands other than the following: (1) National Forest lands; (2) lands administered by the Bureau of Land Management; and (3) Indian trust lands. 6 Indian trust lands. --Indian lands held in trust by the Federal Government, for Indian tribal groups or for individual allotments. State lands. --Lands owned by States or lands leased to these governmental units for 50 years or more. County and municipal lands. --Lands owned by counties and local public agencies or municipalities, or lands leased to these governmental units for 50 years or more. Private Ownership Classes Forest industry lands. --Lands owned by companies or by individuals operating wood-processing plants. Farmer-owned lands. --Lands owned by farm operators. (These exclude lands leased by farm operators from such nonfarm owners as railroad companies and States.) Other private lands. --Privately owned lands other than forest industry and farmer-owned lands . Forest Type and Tree Species Forest types. --A classification of forest land based upon the species forming a plurality of live-tree stocking. Forest trees. --Woody plants having a well-developed stem and usually more than 12 feet in height at maturity. Commercial species. --Tree species presently or prospectively suitable for industrial wood products . Softwoods . — Monocotyledonous trees, usually evergreen, having needles or scalelike leaves. Hardwoods . — Dicotyledonous trees, usually broad-leaved and deciduous. Area Condition Classes Stocking. — Stocking is an expression of the extent to which growing space is effectively utilized by present or potential growing stock trees of commercial species. "Percent of stocking" is synonymous with "percentage of growing space occupied" and means the ratio of actual stocking to full stocking for comparable sites and stands. Basal area is used as a basis for measuring stocking. "Stocking percentages" express current area occupancy in relation to specified standards for full stocking based on number, size, and spacing of trees considered necessary to fully utilize the forest land. Full utilization of the site is assumed to occur over a range of basal area. As an interim guide, 60 percent of the normal yield table values has been used to establish the lower limit of this range, which represents full-site occupancy. This is called 100-percent stocking. The upper limit of full stocking has been set at 132 percent. Sites with less than 100-percent stocking represent less than full-site occupancy. Overstocking is characterized by sites with 133 percent or more stocking. Class 10. --Areas fully stocked (100 to 132 percent) with desirable trees and not overstocked (133 percent or more) . Class 20. --Areas fully stocked with desirable trees, but overstocked with all live trees. Class 30. --Areas medium to fully stocked (60 to 99 percent) with desirable trees and with less than 30 percent of the area controlled by other trees and/or inhibiting vegetation or surface conditions that will prevent occupancy by desirable trees. Class 40. --Areas medium to fully stocked with desirable trees and with 30 percent or more of the area controlled by other trees and/or conditions that ordinarily prevent occupancy by desirable trees. Class 50. — Areas poorly stocked (16.7 to 59 percent) with desirable trees, but fully stocked with growing stock trees. Class 60. --Areas poorly stocked with desirable trees, but with medium to full stocking of growing stock trees. Class 70. — Areas nonstocked (less than 16.7 percent) or poorly stocked with desirable trees, and poorly stocked with growing stock trees. Class 80. --Low-risk old-growth stands. Class 90. --High-risk old-growth stands. Nonstocked. --Areas less than 16.7 percent stocked with growing stock trees. Productivity Productivity class. --A classification of forest land in terms of potential growth in cubic feet of fully stocked natural stands. Stand-Size Classes Sawtimber stands. — Stands at least 16.7 percent stocked with growing stock trees, with half or more of total stocking in sawtimber or poletimber trees, and with sawtimber stocking at least equal to poletimber stocking. Poletimber stands. --Stands at least 16.7 percent stocked with growing stock trees in which half or more of this stocking is in poletimber and/or sawtimber trees, and with poletimber stocking exceeding that of sawtimber. Sapling-seedling stands. --Stands at least 16.7 percent stocked with growing stock trees in which more than half of the stocking is saplings and/or seedlings. Nonstocked land. --Commercial timberland less than 16.7 percent stocked with growing stock trees. Class of Timber Growing stock trees. --Live trees of commercial species qualifying as desirable or acceptable trees. (Excludes rough, rotten, and dead trees.) Desirable trees. --Growing stock trees (1) having no serious defect in quality to limit present or prospective use for timber products; (2) of relatively high vigor; and (3) containing no pathogens that may result in death or serious deterioration before rotation age. Acceptable trees. --Growing stock trees meeting specified standards of size and quality, but not qualifying as desirable trees. Rough trees. --(1) Live trees that do not contain at least one 12- foot saw log or two noncontiguous saw logs, each 8 feet long or longer, now or prospectively, and/or do not meet Rocky Mountain regional specifications for freedom from defect primarily because of roughness or poor form; and (2) all live trees of noncommercial species. Rotten trees. — Live trees that do not contain at least one 12- foot saw log or two noncontiguous saw logs, each 8 feet long or longer, now or prospectively, and/or do not meet Rocky Mountain regional specifications for freedom from defect primarily because of rot; that is, when more than 50 percent of the cull volume (cubic-foot basis) in a tree is rotten. Salvable dead trees. --Standing or down dead trees that are considered merchantable by Rocky Mountain regional standards. Saw-log portion .--That part of the bole of sawtiraber trees between the stump and the saw- log top. A 1-foot stump is used. Upper-stem portion. --That part of the bole of sawtimber trees above the saw- log top to a minimum top diameter of 4.0 inches outside bark or to the point where the central stem breaks into limbs, whichever occurs first.

Net volume equals gross volume less deduction for rot and missing bole sections. Sawtimber volume. — Net volume in board feet of sawtimber trees of commercial species. Net volume equals gross volume less deduction for rot, sweep, crook, and other defects that affect use for lumber. Components of Change Net annual growth. — The increase in net growing stock or sawtimber volume of a specified size class for a specific year. (Components of net annual growth include the increment in net volume of trees at the beginning of the specific year surviving to its end, plus the net volume of trees reaching the size class during the year, minus the net volume of trees that died during the year, minus the net volume of trees that became rough or rotten trees during the year.) Mortality. --Number or sound-wood volume of growing stock trees dying from natural causes during a specified period, usually annually. Removals. --The net volume of growing-stock or sawtimber trees removed from the inventory by harvesting; cultural operations, such as timber stand improvement; land clearings; or changes in land use.
