WP as per WS

  1. 1. By :-Dr. ANOOP BHALLA IFS APCCF(WP)
  2. 2. AIMEnhancement of decreasing Productivity of flora & fauna for ecologically sustainable forest management ( SFM).
  3. 3. OBJECTIVES 1 . Improving Soil Moisture table in forest areas by increasing “Recharge Capacity ” of the Catchment. 2 To enhance the current low productivity of Forest flora caused due to Soil moisture stress . 3 . Decreasing Surface Run off from forest area. 4 . Recharge of Ground water table(especially the forest crop growth zone). 5 . To enhance the capacity of Discharge Zone to increase the agriculture productivity of fringe forest area.
  4. 4. AVERAGE SCENARIO OF A DIVISION1 . Avg. Total Area of the forest division – 1400 Sq km or 140000 ha.2 . Avg. no. of Milli watersheds (Equivalent to Felling Series) in Div – (Only Forest Area).3 . Avg. Area of Milli watersheds (Equivalent to Felling Series) in Div – (Only Forest Area).4. Avg. no. of Micro watersheds (Equivalent to Coupes) in Div – (Only Forest Area).5. Avg. Area of Micro watersheds (Equivalent to Coupes) in Div – (Only Forest Area).6.Treatment cycle – 20 years7. No. of coupes per year treated – 1008. Total Area to be treated in a year in a Division – 7000 ha9. Avg. treatment cost per ha – Rs 4000 per ha10. Total treatment cost in a year / division – 7000X4000 = 28000000 or 2.8 cr.11. Cost for all of the state – 2.80 @ 32 = 89.60 or 100 cr.
  5. 5. SCENARIO OF THE FOREST PRODUCTION MATCHES IN THE STRATA1 . Young to middle aged crop.2 . Conversion decrees.3 . Water as a limiting factor for SFM.4 . Hence watershed management should become basic for SFM.
  6. 6. HOW IT GETS INCORPORATED IN WORKING PLANAt the outset before working plan revision starts ,the Division’s milli watershed are prescribed by WPO from the angle of aims/objects(Criteria shown in next page) –a) Separate integrated watershed management working plan - >25 degree , BD rich , soil erosion area.b) This is not the end but it beginning – Watershed management become integral part of all working circles.a) In each working circle ,we propose two parallel felling series - 1)Sillviculture FS 2) Water Shade FS
  7. 7. WATERSHED TREATMENT1) A separate manual prepared for details of scientific & technical technologies for treatment.2) GIS based software prepared for proper site based treatment map.
  8. 8. PARAMETERS FOR PRIORITIZING OF WATERSHEDS (IN ORDER OFPRIORITY) Slope Percentage . Rills & Streams . Forest Cover. Geo-morphological Formations. Soil Types. Any site specific misc(like Eco tone, BD richness, Ecologically fragile zones etc).
  9. 9. WEIGHTED PERCENTAGE OF PARAMETERS OF WATERSHEDS Slope Percentage . 30 – 55% Rills & Streams . Forest Cover. 20 - 30 % Geo-morphological Formations. 15 - 20% Soil Types. 10 - 15% Any site specific misc(like Eco tone, BD richness, Ecologically fragile zones etc). 0- 5%
  10. 10. Rating For Slope Factor :- Description Slop Value Rate Very Steep Sloping >25% 1 Mod Steep to Steep 10-25% 17 Moderately Sloping 5-10% 34 Very Gently Sloping 0-5% 51
  11. 11. Rating For Vegetation Factor :- Class Values Value Rate Scrub Canopy density less 1 than 10% Open Forest Canopy density between 10 10% and 40% Mod Dense Forest Canopy density between 20 40% to 70% Very Dense Forest Canopy density of 70% 30 and above
  12. 12. Rating For Geomorphology Factor :- Alluvium 1 Sandstone 1 Basalt 7 Granite 14 Gneiss 14 Granite/Gneiss 14
  13. 13. Rating For Soil Factor :- Value Value Rate C, SiCL in flat area 1 SL, S 5 SC, CL, SCL, L, SiL, Si 10 C, SiCL 15 C (Clay), SiCL (Silty clay loam), SC (Sandy clay), CL (Clay loam), SCL (Sandy clay loam), L (Loam), SiL (Silty loam), Si (Silt), SL (Sandy loam), S (Sandy).
  14. 14. Rating Of Watersheds in terms of priority for reducing surface Runoff :- Description Rating Sum Class Extremely Susceptible 0-16 1 Very Highly 17-24 2 Highly Susceptible 25-29 3 Moderately Susceptible 30-48 4 Slightly Susceptible 49-64 5 Insignificantly Susceptible more then 65 6
