The 61-year results from a study of group/patch selection in New Hampshire (four entries, 0.5 ac average opening size) showed that this system will maintain a continued proportion of about 20% of the basal area in bitches and ash, or about one-third in all intolerant/intermediate species.The diameter distribution closely followed the J-shaped curve typical of unevenaged forests. There was a dead standing component of about 20 trees per acre including 3 sawtimber-sized stems. North. J. Appl. For: 16(3):151-153.
