26 STATE P\>RESTRY PROJECTS 



WORKING PLANS. 



A. Shade and ornamental trees. 



1. Make a census of the species of trees on at least the prin- 



cipal streets where planting has been done over a suffi- 

 cient period of time to furnish reliable data. 



2. Adaptability to soil conditions, such as kind of soil, mois- 



ture in soil alkaline soils. 



3. Xote the degree of adaptability to the climatic conditions, 



such as relation to early and late frosts, winds, hail, 

 sleet and snow, and sunburn. 



4. Liability to injuries from insects, fungi, smelter fumes 



and other gases. 



5. Rate of growth and period of maturity. 



6. Objectionable features in habit of growth, tendency to 



litter, and unpleasing esthetic qualities. 



7. General observations concerning the planting methods em- 



ployed; spacing of trees, pruning, beheading or other 

 form of mutilation and other features, desirable and 

 undesirable. 



8. Photographs should be taken of the best types of trees 



and the best planted streets and private places, together 

 with pictures illustrating the common mistakes in plant- 

 ing, pruning, lack of care, or other features. 



B. Timber and Windbreak Plantings. 



A careful study should be made of the principal timber planta- 

 tions in each district, especially where these are of considerable age, 

 as follows : 



1. Species of trees planted; purpose of plantation; form and 



area of plantation ; soil conditions. 



2. History of planting: Date of planting, source of the 



stock; how planted: care as to cultivation, irrigation, 

 pruning, protection from stock and fire. 



3. Measurements : These should comprise the height, trunk 



diameters, rate of growth ; present volume per acre 

 in cordwood, posts, poles, and lumber. 



4. Financial estimates, expenses : Cost of land, taxes, 

 nursery stock, labor, interest. 



Revenues : Fuel or other timber, nuts or other tree prod- 

 ucts ; windbreak service; present value of stand. 

 RECORDS. Permanent records should be compiled in a form 

 suitable for filing. 



In the Shade Tree Survey, the town or city may constitute the 

 filing unit. Each record should bear the altitude, range of tem- 

 perature, and other features affecting the climate, together with 

 the other data given under each topic of study.
