Valen- cia County, as shown in this report, is now divided into Valen- cia and Cibola Counties. Fieldwork conducted by personnel from the New Mexico Division of State Forestry began in Sep- tember 1979 and was completed in November 1979. The 1962 statewide inventory did not sample these counties intensively and did not report findings at the working circle level. The primary objective of Forest Survey, a continuing nation- wide undertaking conducted by the Forest Service, U.S. Department of Agriculture, is to provide an assessment of the renewable resource situation for forest and rangelands of the Nation. Fundamental to the accomplishment of this objective are the periodic State-by-State resource inventories. Originally, Forest Survey was authorized by the McSweeney-McNary Act of 1928. The current authorization is through the Renewable Resources Research Act of 1978. The resource inventories for the Rocky Mountain States of Arizona, Colorado, Idaho, Montana, New Mexico, Nevada, Utah, Wyoming, and western South Dakota are administered by the Intermountain Forest and Range Experiment Station with headquarters in Ogden, Utah. These inventories provide information on the extent and condition of State and privately owned forest lands, volume of timber, and rates of timber growth and mortality. These data, when combined with similar information on Federal lands, provide a basis for the formula- tion of forest policies and programs and for the orderly development and use of the resources. The three-county area covered by this report is one of 11 working circles in New Mexico. Similar reports have been issued for Colfax, Santa Fe, San Miguel, Taos-Rio Arriba and Bernalillo, Sandoval and Torrance Working Circles. A report covering all counties in New Mexico will be issued when the Statewide inventory data have been compiled and summarized. The total land area in McKinley, San Juan, and Valencia Counties is 10,611,007 acres (4 294 140 hectares). Lands managed by the Forest Service; and the U.S. Department of In- terior’s Bureau of Land Management, National Park Service, and Indian trust lands together account for 7,288,880 acres (2 949 717 hectares), or 69 percent of this land. The remaining 3,322,127 acres (1 344 423 hectares) are in State, private, and other ownerships. DATA PRESENTED HERE ARE FOR STATE, PRIVATE, MISCELLANEOUS FEDERAL, AND A SMALL ACREAGE OF COUNTY AND MUNICIPAL LANDS ONLY. Highlights show the area of commercial timberland in com- parison to total forest land area and the distribution of this area by forest type, stand-size class, and site class. Discussions of the data reliability and terminology are included. These two items should be reviewed carefully when using this information. HIGHLIGHTS Area e The forest land area is 768 thousand acres (311 thousand hectares), or 23 percent of the total State and private land area in McKinley, San Juan, and Valencia Counties. e Of the forest land, 65.9 thousand acres (26.6 thousand hectares), almost 9 percent, is classified as commercial timberland. e Private ownership accounts for 60.6 thousand acres (24.5 thousand hectares), or 92 percent of the commercial timberland. Ponderosa pine is the predominant type and occupies 91 per- cent of the commercial timberland. Douglas-fir, cottonwood, and aspen cover the remaining area. Over half of the commercial timberland is in the 20 to 49 cubic foot productivity class; 92 percent of this is privately owned. Inventory e Growing stock volume amounts to 43.4 million cubic feet (1.2 million cubic meters) and sawtimber volume totals 177.9 million board feet. e Rough, rotten, and salvable dead trees comprise 6.5 million cubic feet (185 thousand cubic meters), 13 percent of the total sound wood volume. The largest share of the total growing stock volume is made up of ponderosa pine (92 percent). Aspen, Douglas-fir, cot- tonwood, Engelmann spruce, and pinyon/juniper account for the remaining volume. Although pinyon/juniper usually occurs on unproductive forest land, when it occurs in mix- tures with commercial species on productive sites, it is re- ported in the commercial timberland statistics. e Private owners control 92 percent of both the total growing stock and the sawtimber volume.

Growth and Mortality e Net annual growth of growing stock totals 1,169 thousand cubic feet (33 thousand cubic meters). Growth and mortality were not measured for pinyon and juniper trees. e About 93 percent of the total net growth is on private lands. The annual mortality of 43 thousand cubic feet (1 thousand cubic meters) offsets 4 percent of the gross annual growth. HOW THE INVENTORY WAS CONDUCTED The inventory was designed to provide reliable statistics primarily at the State and working circle levels. Procedures were: 1. Initial area estimates were based on the classification of 11,340 sample points systematically placed on the latest aerial photographs 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 com- pute area expansion factors for the field stratum means. 106 105 104 103 102° COLFAX Gin) é GUADALUPE ie TORRANCE 106 105 104 103 102° 2. Land classification and estimates of timber characteristics and volume were based on observations and measurement re- corded at 295 ground sample locations of which 177 were forested. Sample trees were selected using a 10-point cluster which includes fixed plots (1/300 acre) for trees less than 5.0 inches diameter at breast height (d.b.h.) and variable plots (40 BAF [basal area factor]) for trees 5.0 inches d.b.h. or larger. 3. Equations prepared from detailed measurements collected on standing trees throughout the Southwest were used to com- pute the volume and defect of individual tally trees. 4. All photo and field data were sent to Ogden, Utah, for editing and were punched onto cards and stored for machine computing, sorting, and tabulation. Final estimates were based on 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 result in high sampling errors. The standard error percents shown in tables 1 and 2 were calculated at the 67 percent confidence level.

Other forest land.—Forest land incapable of producing 20 cubic feet per acre of industrial wood under management, be- cause 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. Public Ownership Classes National Forest lands.—Federal lands legally designated as National Forest or purchase units and other lands under the administration of the Forest Service, including experimental areas and Bankhead-Jones Title III lands. Bureau of Land Management lands.—Federal lands adminis- tered by the Bureau of Land Management. Indian lands.—Tribal lands held in fee by the Federal Gov- ernment, but administered for Indian tribal groups and Indian trust allotments. State lands.—Lands owned by States, or lands leased to these governmental units for 50 years or more. Private and Other 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. Forest industry lands.—Lands owned by companies or by in- dividuals operating wood-processing plants. Farmer-owned lands.—Lands owned by farm operators. (These exclude lands leased by farm operators from such non- farm owners as railroad companies and States.) 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 lands. Miscellaneous 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.—Coniferous 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 stock- ing’’ is synonymous with ‘‘percentage of growing space occu- pied’”’ 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 understocking with 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) to 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. Class of Timber Growing stock trees.—Live trees of commercial species qual- ifying as desirable or acceptable trees. (Excludes rough, rotten, and dead trees.) Desirable trees.—Growing stock trees (1) having no serious defect in quality limiting 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 or longer, now or prospectively, and/or do not meet Rocky Mountain regional specifications for freedom from defect pri- marily 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 or longer, now or prospectively, and/or do not meet Rocky Mountain regional specifications for freedom from defect pri- marily 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 sawtimber 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. Tree-Size Classes Seedlings.—Live trees less than 1.0 inch d.b.h. Saplings.—Trees 1.0 to 4.9 inches d.b.h. Poletimber trees.—Trees at least 5.0 inches d.b.h., but smaller than sawtimber size. Sawtimber trees.—Trees exceeding poletimber size. In the In- termountain States, the minimum d.b.h. for softwood saw- timber is 9.0 inches and for hardwoods 11.0 inches. Volume Cull volume.—Portions of a tree’s volume that are not usable for industrial wood products because of rot, form, or other defect. Net volume.—Gross volume less deductions for cull. Growing stock volume.—Net volume in cubic feet of live sawtimber trees and live poletimber trees from stump to a mini- mum 4.0-inch top (of central stem) outside bark. 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 af- fect use for lumber. Growth and Mortality Net annual growth.—The increase in net growing stock volume of a specified size class for a specific year. (Compo- nents of net annual growth include the increment in net volume of trees at the beginning of the specific year and 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 rot- ten trees during the year.) Mortality.—Number or sound-wood volume of growing stock trees dying from natural causes during a specified period, usually annually. Site Site class.—A classification of forest land in terms of in- herent capacity to grow crops of industrial wood. Site classifications are based upon the mean net annual growth of growing stock (not including thinnings or mortality loss) attainable at culmination of mean net annual growth over age. Height-age relationships are usually used as indicators of the specified volume-site class. 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 stock- ing 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 stock- ing is saplings and/or seedlings. Nonstocked land.—Commercial timberland less than 16.7 percent stocked with growing stock trees.

Forest area and timber resource statistics for State and private lands in McKinley, San Juan, and Valencia Counties, New Mexico, 1979. Resour. Bull. INT-31. Ogden, UT: U.S. Department of Agriculture, Forest Service, Intermountain Forest and Range Experiment Station; 1983. 22 p. Presents land area, commercial timberland area, timber inventory, and growth and mortality data based on Forest Survey standards. KEYWORDS: forest surveys (regional), forest area classification, stand volume The Intermountain Station, headquartered in Ogden, Utah, is one of eight regional experiment stations charged with providing scientific knowledge to help resource managers meet human needs and protect forest and range ecosystems. The Intermountain Station includes the States of Montana, Idaho, Utah, Nevada, and western Wyoming. About 231 million acres, or 85 percent, of the land area in the Station territory are classified as forest and rangeland. These lands include grasslands, deserts, shrublands, alpine areas, and well-stocked forests. They supply fiber for forest in- dustries; minerals for energy and industrial development; and water for domestic and industrial consumption. They also provide recreation opportunities for millions of visitors each year. Field programs and research work units of the Station are maintained in: Boise, Idaho Bozeman, Montana (in cooperation with Montana State University) Logan, Utah (in cooperation with Utah State University) Missoula, Montana (in cooperation with the University of Montana) Moscow, Idaho (in cooperation with the Univer- sity of Idaho) Provo, Utah (in cooperation with Bigham Young University) Reno, Nevada (in cooperation with the University of Nevada)
