Sampling errors given in table I are based on one standard deviation or a probability of two chances out of three.

Current f o r e s t industry tixnberland holdings have decreased £ran 267,500 ac res i n 1974 t o 159,600 acres, Mnin- d u s t r i a l p r iva te m e r s h i p of t f e l l 6 percent to 2,094,100 acres, mainly because of conversion to a g r i c u l t u r a l land. For canparison between 1974 and 1984 surveys, nonindustr ial p r iva te tim- berland t h a t was leased to f o r e s t indus- t r y w a s reported i n f o r e s t industry tim- berland acreage,

F o r e s t T y p e

No significant changes in forest type occurred except in the elm- ash-cottonwood type. That type fell from 348,700 acres to 243,400 acres, a 30-percent drop. The dominant for- est type in the South Delta unit is oak-gum-cypress, occupying 1,989,800 acres, 83 percent of total timber- land.

S t a n d S i z e

Acreage of sawtimber stands in- creased 7 percent (118,800 acres) to 1,806,700 acres, while poletimber and sapling-seedling stands fell 197,800 and 128,700 acres, respectively. Currently, poletimber stands occupy 356,500 acres and sapling-seedling stands occupy 101,400 acres.

S o f t w o o d V o l u m e

Cypress makes up 92 percent of softwood growing-stock volume in the South Delta unit. Total softwood growing-stock volume increased to 1,306 million cubic feet, currently. Softwood sawtimber also increased to 4,800 million board feet in 1984.

H a r d w o o d V o l u m e

Hardwood growing-stock volume rose to 2,544 million cubic feet. Sawtim- ber volume also increased to 7,825 million board feet.

G r o s s G r o w t h

Gross growth for softwood growing- stock stands averages 10 cubic feet per acre per year. Gross growth for hardwood growing stock averages 37 cubic feet per acre per year.

Softwood sawtimber gross growth averages 60 board feet per acre per year while hardwoods average 150 board feet per acre per year.

R e m o v a l s

Annual growing-stock removals on tixnberland during the 1984 survey period averaged 5 million cubic feet for softwoods and 23 million cubic feet for hardwoods. The growth- to-removals ratios are 4.8-to-1 for softwoods and 2.7-to-1 for hardwoods.

N u m b e r of T r e e s I i

f

The rider of live sapling-size softwood trees has declined 7 percent i since the 1974 survey. However, the ' number of live softwood trees larger than 5.0 indhes has increased 14 per- cent. Currently, cypress makes up 73 percent of sapling-size and 90 per- cent of trees greater than 5.0 inches in the softwood species group. The number of live sapling-size [

hardwood trees has decreased 9 per- j I

cent. There was no change in -the number of live hardwood trees greater than 5.0 inches (less than a 1- per- cent decrease) . N e t I n v e n t o r y C h a n g e

Softwood growing stock increased 18 million cubic feet annually. Soft- wood sawtimber increased 110 million board feet annually. Hardwood growing stock increased at

an annual rate of 38 million cubic feet while hardwood sawtimber rose 205 million board feet annually.

M o r t a l i t y

Annual mortality for softwood grow- ing stock is 2 million cubic feet per year, down from 17 million cubic feet per year reported for the 1974 survey period. Hardwood mortality is cur- rently 28 million cubic feet per year, a decrease from 34 million cu- bic feet per year reported in 1974.

C u l l V o l u m e

Currently, cull volume for soft- woods is 132 million cubic feet, a 22- million cubic foot decline since the 1974 survey period. Hardwood cull volume is 938 million cubic feet, a

large increase since the 1974 survey. A total of 630 million cubic feet of hardwood cull was reported for that period. Softwood cull is 9percent of total softwood live tree volume. TFlenty-seven percent of total live hardwood volume is in hardwood cull trees.

DEFINITION O F TERMS

.-- Aver- age annual sound-wood volume of live trees, dying from natural causes.

. - -Average annual net volume of growing-stock trees removed from the inventory by harvesting, cultural operations such as timber-stand improvement, land- clearing, or changes in land use.

. - -Aver - age annual net volume increase for the inter-survey period.

. --A classification of forest land based upon the species forming a plurality of live-tree stocking.

.--Live trees of commercial species. Rough and rotten trees are excluded.

.--Net volume in cubic feet of growing-stock trees at least 5.0 inches in diameter at breast height, from a 1-foot stump to a minimum 4.0-inch top diameter out- side bark of the central stem, or to the point where the central stem breaks into lirribs .

.--Tree spe- size, poor which nor-

mally do not develop into trees suit- able for industrial wood products.

. - -A classifi- cation of forest land according to

the availability of moisture for tree growth. Xeric-low or deficient in moisture. Mesic-a moderate amount of moisture. Hydric-an abmdance or over abundance of moisture.

.--Growing-stock trees of comercial species at least 5.0 inches in diameter at breast heicjht;, but smaller than sakrrtimber size,

.--Live trees of com- mercial species that do not contain at least one 12-foot saw log, now or prospectively, primarily because of rot.

. --Live trees of com- mer s that do not contain at least one 12-foot saw log, now or prospectively, primarily because of

ss or poor form. (Includes all live trees of noncommercial species. )

. --Live trees that are of commercial species, contain at least a 12-foot saw log, and meet regional spci f ications for f redom from defect. Softwoods must be at least 9.0 inches in diameter at breast height and hardwoods at least 111.0 inches.

. --Net volume of the saw-log portion of live sawtimber in board feet, International 1/4-inch rule and in cubic feet.

. --A classification of forest land in terms of inherent capacity to grow crops of industrial wood,

--A classi f ica- tio as& on the size class of qowing-stodk trees on t k area: that is, sawti or sapling and seedling.

.--Forest land that is is capable of produs-
