Division of Forestry 



Honolulu, Hawaii, May 25, 1917. 



Board of Commissioners of Agriculture and Forestry, Honolulu. 

 Gentlemen : — I respectfully submit the following routine report 

 of the Division of Forestry for the month of April, 1917: 



Forest Reserve Planting. 



The reforestation of the open government land in upper jManoa 

 Valley within the Honolulu Watershed Forest Reserve was con- 

 tinued during the month by the planting out of about 500 koa 

 trees. Since this is mainly a water conservation project, this 

 native species of tree has been largely used, although a few intro- 

 duced trees have also been planted on the drier slopes and ridges 

 to determine their adaptability to the region. Since the first of 

 the year the following trees have been planted at this place : 



Koa {Acacia koa) 1259 



Japanese cedar (Cryptomeria Japonica) 850 



Benguet pine (Finns i]isularis) 50 



Cook pine (Araucaria Cookii) 50 



Total number of trees planted. . 2209 



The planting of koa trees in the Makiki valleys has continued 

 and a considerable number of junipers have also been set out. 

 From the last crop of seed, several thousand young mahogany 

 trees (Szvietonia niahogani) are being raised for close forest 

 planting in the main Makiki Valley just back of the nursery for 

 the purpose of commercial timber production. 



On April 13 there were planted out in the open piece of land 

 just mauka of the Tantalus eucalyptus forest, and near General 

 Davis' house, 37 trees which Mr. J. F. Rock had kindly brought 

 back from the Philippines in September, 1916, for this Division. 

 They consist of the important timber trees of the Philippine 

 Islands, and for the purpose of permanent record their names are 

 given herewith:
