ENEMIES  OE  THE  HAWAIIAN  FOREST. 
Many  causes  have  been  proclaimed  as  being  responsible  for 
the  destruction  of  our  island  forests.  The  disappearance  of 
the  native  birds  before  their  more  pugnacious  introduced 
rivals,  has,  it  has  asserted,  left  the  indigenous  boring  insects 
without  their  natural  enemies.  The  presence  of  cattle  and 
goats  has  destroyed  the  mature  plants  and  trampled  the  seed- 
ling out  of  existence.  These  and  many  other  harmful  agencies, 
all  of  them  without  doubt  contributive  causes  to  the  havoc 
wrought,  have  at  various  times  been  accused  as  the  chief 
agents.  Be  this  as  it  may,  it  seems  to  be  recognized  that  the 
chief  way  to  safeguard  the  Hawaiian  forest  is  to  preserve  the 
ground  herbage  whatever  that  may  consist  of.  Any  means  of 
protecting  the  growth  of  grass,  fern,  creeper  or  any  plant 
life  which  conserves  the  moisture,  protects  the  root  systems  of 
the  trees  or  affords  cover  for  the  tender  seedling,  is  directly 
working  for  the  benefit  of  the  Hawaiian  forest.  At  the  same 
time  any  factor  tending  to  destroy  these  growths  may  be  re- 
garded as  inimical. 
The  salvation  of  the  Hawaiian  forest  will,  in  addition  to 
direct  replanting,  be  found  in  the  elimination  of  causes  un- 
favorable to  the  ground  cover  and  the  adoption  of  methods 
suitable  to  its  recovery.
