Beginning in July, 1913, with the preparations for planting, 

 some 23 acres have now feen set out. The Koa trees are spaced 

 15 x 15 feet, with the intention of securing a complete cover on 

 the slopes. It is expected that this planting will be continued 

 over all the open ridges between Sugar Loaf and the Tantalus 

 forest. 



Another planting project carried forward by the Division of 

 Forestry has been the continuation of the tree planting under- 

 taken by the Alexander & Baldwin interests on Government land 

 along the Koolau Ditch system on windward Maui. Begun in 

 1911 under a planting plan drawn up by the Division of Forestry, 

 the purpose of this planting is to assist in restoring the dense 

 cover of vegetation on portions of this important watershed which 

 had been opened up through the dying off of the forest during the 

 years 1906 to 1908. The work of the past year has been primarily 

 in caring for the seedlings previously planted until they became 

 established, and in extending somewhat the areas set in trees. In 

 part this planting is experimental. Various species of Eucalyptus 

 are being tried out, while attention has also been paid to increas- 

 ing the spread of Koa and of the native Bamboo. 



Further, in the way of experimental tree planting, the Divi- 

 sion of Forestry has made progress during the past two years. 

 Under its auspices such planting is now in progress in five locali- 

 ties : two on Maui, two on Oahu and one on Kauai. Those on 

 Maui are at Kailiili, above Makawao, and on the Government 

 remnant called Polipoli, above Wailuku in the West Maui Forest 

 Reserve. At Kailiili, through an arrangement with the ,Maui 

 Agricultural Co., a number of species of Eucalypts are being 

 planted in definite plots on a section of open land in the Makawao 

 Forest Reserve, in return for the privilege granted that Company 

 of removing dead wood from the land. 



Among the trees being tried at Kailiili are the following 

 species of Eucalypts: E. gomphocephala ,E. gonio calyx, E. hemi- 

 l>hloia, E. longifolia, E. leucoxylon, E. macrorliyncha, E. macu- 

 lata, E. marrginata, E. paniculata, E. polyanthemos, E. punctata, 

 E. saligna, E. siderophloia, E. sideroxylon, and E. tereiicornis. 



Other trees in the plantation are: Pinus massoniana, P. c<tn- 

 uncnsis, P. radiate, and P. tuberculata. 



On the windward of the block is a belt of Eucalyptus robusta. 



Each species is in a plot by itself, plainly marked by a stake 

 with a metal tag bearing the tree name and the date of planting. 

 The object is to try out valuable species at present imperfectly 

 known in Hawaii. Those that are found to do well at Kailiili 

 can later be recommended for other localities where the conditions 

 are similar as to elevation, rainfall and wind exposure.
