AN AUSTRALIAN STUDY OF AMERICAN FORESTRY. 93 
for some such period as ten to fifteen years. ‘The varying divisions of the 
forest required are indicated under each section of the plan. It is intended 
that the outline shall be followed only so far as it applies to the local conditions 
covered by the plan. 
I.—GENERAL DESCRIPTION. 
General data which relates to two or more sections of the plan, or which 
can be treated more logically here than under other sections. Under most 
headings the discussion will be a summary of important points treated in detail 
in other sections of the plan. 
Creation. Area, past and present. Totals of alienated lands by classes. 
(Tabulated form.) 
Physical features. (Concise. Include the information which has a distinct 
bearing upon or forms the basis for the provisions of the plan.) 
Climate. (Data not of direct application may be placed in the appendix.) 
Topography. (For use in the division of the forest into working circles, 
as well as its bearing upon use, development, and administration of the forest.) 
Geology. (As it affects soils, &c.) 
Soils. (In such form that statement may be applied directly in silvicul- 
tural practice, settlement, policy, &c.) 
Land Classification. Forest, agriculture, grazing, barren, &c. Tabulated. 
Brief discussion, if necessary.) 
Transportation. (Railroads, water, &c., only as it affects the adminis- 
tration or the development of the forest.) 
Settlement. Present and probable future. (As it affects the forest and 
the plan.) 
Industries. Mining, grazing, ranching, lumbering, &c. (Only as they 
have a bearing on the plan.) : 
II.—SILVICULTURE. 
TIMBER. 
Estimates and detailed descriptions of timber. 
Estimates by species, separately by divisions, blocks, and other natural 
or artificial subdivisions. Quality, and condition of timber, age classes if 
stand is even-aged, accessibility, information on logging, &c., as necessary, 
cutover areas. (Tabulation.) 
Forest Types.—Composition, occurrence, distribution of age classes, and 
condition of timber. (Concise general descriptions and the fundamental 
silvicultural requirements and principles which form the basis for the choice 
and application of silvicultural systems.) 
Species.—Concise. Treat, from the standpoint of the type and the stand 
rather than the individual tree, the characteristics and requirements upon 
which will be based-conclusions regarding the species to be favoured and the 
relation in the management of each species to. the others in the stand or type. 
Climatic, soil, moisture, and light requirements. 
Growth, form, volume, &c. (Tables to be included in the plan if they 
will be used frequently, otherwise in the appendix.) 
Reproduction. Advance reproduction present. Conditions necessary to 
secure it.
