The present investigation was carried out in Forest Division of Himachal Pradesh (H.P.) from nearly 1100 m to 1400 m amsl. Study was conducted in three periodic blocks (PB-I, IN and IV) under pure and mixed crop. The maximum number of recruits of Pinus roxburghii Sarg. (Chir pine) was found in PB-I followed by PB-IN of pure Chir pine crop. While the unestablished regeneration of Pinus roxburghii was absent in PB-IV of mixed Chir pine crop. The maximum regeneration success was in PB-I and maximum established stocking percent was in PB-IV of the Chir pine species wasfound in pure crop. Regeneration success of Chir pine followed the sequence PB-IV>PBI>PB-IN. The results of the present study suggest that there is no well defined and clear effect of the neighbouring vegetation on Chirpine regeneration.

Abstract


The present investigation was carried out in Forest Division of Himachal Pradesh (H.P.) from nearly 1100 m to 1400 m amsl. Study was conducted in three periodic blocks (PB-I, IN and IV) under pure and mixed crop. The maximum number of recruits of Pinus roxburghii Sarg. (Chir pine) was found in PB-I followed by PB-IN of pure Chir pine crop. While the unestablished regeneration of Pinus roxburghii was absent in PB-IV of mixed Chir pine crop. The maximum regeneration success was in PB-I and maximum established stocking percent was in PB-IV of the Chir pine species wasfound in pure crop. Regeneration success of Chir pine followed the sequence PB-IV>PBI>PB-IN. The results of the present study suggest that there is no well defined and clear effect of the neighbouring vegetation on Chirpine regeneration.
