 Cooperation in Securing Commercial and Botanical Range Data 



The extension of our present knowledge of the range and habit of native trees is 

 largely dependent upon the cooperation of all members of the Service in securing 

 field notes on the botanical and commercial distribution of North American trees. 

 This cooperation must be voluntary in character or form only a minor part of assigned 

 field work, yet a great deal of information can be secured in this way, useful both to 

 the men in the field and to the Forest Service as a whole. While in the field, members 

 of the Service often come across trees not common in the forest characteristic of the 

 region and of whose botanical identification they are not certain. If in all such 

 cases the field man will secure specimens of mature foliage and if possible of flowers 

 and fruits, and send them to the Forester accompanied by accurate field notes, the 

 specimens will be identified by the Washington office and the man in the field 

 promptly informed. Such cooperation must necessarily increase the acquaintance 

 of the field men with the forest flora and add to our general knowledge of the range 

 of species. 



In order to facilitate the collection of such range data, Form No. 767-s has been 

 revised, with the view of making it suitable for the use of those who are to collect 

 commercial and botanical range notes in the field. It is in the form of an herbarium 

 label, but includes spaces for describing the occurrence of the species. It is printed 

 in notebooks of 100 pages perforated into two parts, one of which is to be torn out 

 and attached as a label to the herbarium specimen, the other remaining in the note- 

 books as a stub record. Unless the herbarium specimens are accompanied by full 

 notes as to the exact locality, altitude, occurrence, associated species, and so on, 

 they will not prove of great assistance in securing definite information on commercial 

 and botanical distribution. It is therefore essential that all of the spaces provided 

 in the form be carefully filled out in the field. For the proper identification of the 

 specimens the material must be carefully selected; and, as many species can not be 

 identified by foliage alone, flowers and fruits must be secured whenever possible. 

 Specimens can be shipped in boxes, paper, or any other package most convenient 

 to the field men. 



As range data are compiled in the form of maps available for use by all the members 

 of the Forest Service, it is essential that all field men cooperate as far as they can 

 in securing notes on distribution.
