MAPPING OF FUEL WOOD TREES IN KOLAR DISTRICT
USING REMOTE SENSING DATA AND GIS

Conclusions :
 
    Land cover analyses show that Kolar District has a vegetative 
      cover (Forest, Agriculture  and  Plantation) of 49.3% and non-
      vegetative cover of 50.7%. 
    Talukwise  land  use  analyses  show  that  among  11  taluks, 
      Bangarpet  has  maximum forest  cover of 10.46%,  followed by 
      Srinivasapur (6.61 %), Chikballpur (4.78 %) and  Gauribidanur 
      has cover of 0.58%. Area under plantation ranges  from  8.81% 
      (Bangarpet)  to  0.08% (Gauribidanur). Area under agriculture 
      ranges from 63.91% (Malur) to 32.21 % (Bagepalli). 

    Wasteland in the district is about 42.33 %  and  talukwise it 
      ranges from 25.97% (Malur)to 56.99 % (Gauribidanur) to 57.60% 
      (Bagepalli).

    Villagewise  land use analyses show the spectral signature of 
      Prosopis  juliflora is in the  range  93-104  and  for  adult 
      plants range  is  95 - 97,  which is mapped  in  Gauribidanur  
      taluk.  Validation  and  verification  indicate  the level of 
      accuracy of 88%.

    Prosopis  juliflora standing biomass production is about 57±3.5 
      t/ha and annual litter productivity is about 7.4±1.13 t/ha with 
      MAI (Mean Annual  Increment) and CAI (Current Annual Increment) 
      of six years. 

    Annual productivity of Prosopis  juliflora in  Gauribidanur  is 
      about  39,990  tonne/hectare. Fuelwood  demand is about 124,212 
      tonne/year, which  means that Prosopis  juliflora  patches meet 
      about 32.2 % of  annual fuel wood demand.
