Tree Investigation 



The working plan, referred to in the foregoing letter, of an 

 investigation to determine the different species of trees which are 

 best adapted in the different parts of the Territory for different 

 specific purposes, was approved by the Board of Commissioners 

 of Agriculture and Forestry on November 28, 1916, and is as 

 follows : 



Working Plan of an Investigation to Determine the Different 

 Species of Trees Which arc Best Adapted in the Different 

 ■Parts of the Territory of Hazi'aii for: 



I. The conservation of water and the protection of water- 

 sheds. 



II. The prevention of sand or dust drifting. 



III. The re-forestation of eroded and arid areas on slopes of 

 mountain ranges and on plains. 



IV. The production of firewood. 



V. The production of timber, fence posts, railroad ties and 

 telephone poles. 



To be conducted by the Division of Forestry with cooperative 

 assistance from the College of Hawaii by furnishing botanical 

 advice and conducting wood technology tests. 



It is assumed that only those species of trees will be considered 

 which have the ability to grow under the different conditions, 

 which are easily propagated from seed or slip, are readily handled 

 in planting operations, and the seed or slips of which are readily 

 obtainable. 



In presenting names of trees, both the common and botanical 

 names should be given in order to avoid any confusion. 



For convenience in this investigation the islands are divided 

 into the following main regions and the finally determined species 

 of trees should be tabulated by these regions : 



1. The wet regions bearing water producing or protection 

 forests. 



2. The regions bearing non-water producing or commercial 

 forests. 



3. The arid and exposed regions. 



/. The Conservation of Water and the Protection of JJ^atersheds. 



Prepare a list of both indigenous and introduced tropical and 

 5ub-tropical trees, which from actual observation and study are 

 already known to be suitable for forest cover on water-producing 

 areas at various elevations. 



Extend the list, so obtained, by a series of further observations 

 during the period of this investigation.
