PLAN FOR PERMANENT SAMPLE PLOTS IN THE 

 ADIRONDACKS^ 



There is need for a systematic study of cut-over areas in the Adiron- 

 dacks. It is impossible to predict to any degree of accuracy the net 

 increment of the trees left after cutting, the height and diameter growth 

 of individual trees, the death rate of some of the older trees, nor is it 

 possible to foretell the actual effect on reproduction and on the remain- 

 ing stand of the different methods of cutting. The most pressing need 

 of today is to ascertain actual increment under different methods of 

 cutting and actual results in reproduction. These plots are designed to 

 ascertain what happens, leaving to later, more intensive plots the stiwly 

 of why it happens.^ 



obje;ct of sample plots 



The general object of these permanent sample plots is to secure accu- 

 rate data under different methods of cutting along the following lines 

 as a foundation for a system of management : 



1. Actual increment in feet board measure or cubic feet per unit of area. 



2. Height and diameter growth of individual trees. 



3. Death rate in different age classes or diameter classes. 



4. Changes and development in young growth. 



5. Accurate photographic record to supplement paragraph 4. 



LOCATION AND AREA 



Areas should be selected in accordance with the attached memoran- 

 dum. It is desirable that plots one acre in size be established where 

 one general density, exposure, type, or aspect would be included ; other- 

 wise areas of one-half or one-quarter acre should be selected which 

 embody a single feature. No plot of over one acre or under one-quar- 

 ter acre should be established. They should be rectangular in shape. 

 The square is a convenient form. 



ESTABLISHMENT 



The co-operation of land-owners and their contractors should be 

 enlisted in order that the plots may not be molested.

 American Foresters, at the meeting at Utica, N. Y., March 14, 1918. 



^The need of such intensively studied plots is also great, and it is to be hoped 

 that a few of these will be established as soon as possible.
