WORKING PLAN FOR MAUNALUA FOREST RESERVE 

 KOOLAUPOKO, OAHU. 



INTRODUCTION. 



At the informal request of A. F. Judd, Esq. a Trustee of the 

 Bernice P. Bishop Estate, the following plan has been prepared 

 for the protection of the remaining native forest and the re- 

 forestation of denuded areas in the Maunalua Forest Reserve in 

 the District of Koolaupoko, Island of Oahu, Territory of Hawaii. 



LOCATION AND TOPOGRAPHY 



The land under discussion consists of 56 acres at the upper end 

 of Kaalakei Valley in Maunalua, Koolaupoko, Oahu, with the 

 Kuliouou Forest Reserve on the west and the steep Waimanalo 

 Pali on the north. The lowest point on the area is 1300 feet and 

 the highest point 2020 feet above sea level. The land is naturally 

 divided into five small "hanging" valleys, that is, eroded gulleys 

 which are separated from the land below by clififs. 



FOREST DESCRIPTION 



The largest and most heavily forested valley is at the west side 

 of the reserve and in this there is a small stream of water which 

 it is believed runs perpetually. Toward the east end of the reserve 

 the forest lessens in density and on the eastermost boundary 

 ridge there are scarcely any trees. 



The reserve embraces the easternmost indigenous wet forest 

 on the island of Oahu which is worth preserving for its scenic 

 value, if for no other purpose. It is situated in a position which, 

 in general, is exposed to the strong trade, winds. A forest cover 

 in this region is very essential for preventing soil and wind 

 erosion and if the remaining forest on this area-should be des- 

 troyed, the protecting influence which it has on the forests to 

 the west would be lost and the general forest line would be 

 pushed further to the west. To prevent this, is one of the main 

 purposes which this resen^e will serve. 



The preponderant tree in this reserve, as in other wet forests, is 

 ohia lehua with the usual undergrowth of amaumau and other 

 ferns, maile and ie-ie vines, naupaka, lobelia, ti and other bushes. 

 The bulk of this occurs in the north-west corner of the reserve 

 almost as a pure stand. Toward the south-west corner down 

 the ridge other species of trees, which naturally occur in drier 

 situations, are encountered. These are represented in fewer 

 numbers by the olapa, mamaki, lama, kopiko olopua and iliahi. 

 These all occur in the region of settling clouds between the eleva- 

 tions of 1500 and 2000 feet. 



Toward the east end of the reserve ^the vegetation grows more 

 scanty because of shallow soil and exposure to strong winds and 

 only kukui and ti are found in the protected pockets of good soil.
