Management of Oaks (Quercus species) – Species Management

MANAGEMENT OF OAKS
o   DESCRIPTION
1.     Oak forests occur all over the Himalaya at altitudes up to 3000 meters (9900 feet) are even more.
2.     The following types of Oaks are very common in the Himalayan region at different elevation.
i.    Quercus incana (White oak, Rin)
ii.   Quercus dilatata (Green oak, Barangi)
iii. Quercus ilex  (Holmoak, Shabaloot)
iv.  Quercus semicorpifolia (Brown oak, Keru)
o   OBJECTS OF MANAGEMENT
1.     To improve the stocking of these forests.
2.     To meet the local demand of people for fuelwood, fodder, and wood for agricultural implements.
3.     To provide sustained yield of fuelwood and fodder is scarcity period.
4.     Carbon Sequestration
o   FELLING SERIES
Depending upon the local conditions a number of felling series may be constituted.
o   Rotation and regeneration period
These are fixed as under:-
PERIOD
YEAR
i.
Rotation for coppice crop
45
ii.
Rotation for standards
90
iii.
Regeneration
15 to 20
o   METHODS OF EXECUTING FELLING
1.         Yield control is on basis of area. Hence an annual coupe is delineated as per the prescribed yield.
2.         This coupe is marked on the ground by clearing a meter wide strip.
3.         Standards falling in the 30 to 40 cm diameter class are retained at the rate of 50 to 60 trees per hectare.
4.         The number of standards is more in areas which are liable to serve soil erosion; steep terrain etc.
5.         Felling is avoided along Nalas, watercourses.
6.         A stool of about 10 to 15 cm height is retained. The stool is dressed in a manner that the cut surface slopes at an angle and no depression or cavity occurs in the center to help the rainwater to drain off and prevents the stem from rotting.
7.         The young regeneration of coniferous seedlings which appears here and there are not damaged during felling operations. In facts, they are preserved and tended.
8.         All fellings must be completed by the middle of March.
9.         No markings are carried out in unculturable areas.
10.       The shrubs and climbers which interferes with the growth of the coppice crop are immediately cut and removed from the coupe.
o   REGENERATION
1.     A new crop is obtained by means of stool shoots.
2.     Where regeneration is not adequate, sowings are done in patches.
3.     In certain cases, planting of nursery-raised seedlings is also carried out in order to supplement regeneration.
4.     Grazing and browsing should be eradicated from regeneration areas.
