Silvicultural system or method Clearcut NR Shelterwood CR Risk of exotic invasion should be low Single-tree selection R Group selection CR—should be used more to perpetuate intolerant and mid-tolerant species. Risk of exotic invasion should be low Stand improvement R—in combination with single-tree selection or crop tree management in degraded or unhealthy stands Crop tree R—especially in young even-aged stands NR R—most commonly recommended to develop even-aged, high composition of oak —needs follow-up CR—does not maintain growth of mid-tolerant seedlings R—develop patches of oak regenerationcontinuously maintains high forest canopy—needs followup R—in combination with shelterwood, group selection or crop tree management in degraded or unhealthy stands R—especially in young even-aged stands CR—provided site protection, aesthetics, hydrology, regeneration, and tree conservation by-law concerns have been addressed CR—significant blowdown potential with shallow-rooted species CR—if limited tolerant species also consider using some group selection CR—usually needs monitoring and possible follow-up regeneration or tending work R—in combination with any of the other recommended approaches R—especially in young even-aged stands CR—where aesthetics, ecological objectives, and tree conservation by-laws permit R—most commonly recommended for regeneration of mature white and red pine stands CR—where component of hardwoods approaches 50% or more CR—for establishing or releasing hardwood or pine regeneration CR—except in degraded stands or ones with health issues R—especially in mixed stands or younger plantations CR—where aesthetics, ecological objectives, and tree conservation by-laws permit CR—for small white cedar stands or using red cedar to protect hardwood regeneration CR—for continuous cover using light thinning targets CR—no more than 20% of stand during any cutting period CR—in middle-aged (50 to 80 years) white cedar stands —thinning from below R—in red cedar CR—in white cedar later years (80+), as lead—up to shelterwood NR CR—where aesthetics, ecological objectives, and by-laws permit— especially where native species become well established CR—in stands with no potential for development of mature stems and no regeneration R—commonly recommended as nurse crop for hardwood or conifer regeneration CR—for mature stands > 24cm dbh* CR—where component of hardwoods approaches 50% of more R—gaps of half the canopy height CR—for establishing or releasing hardwood or pine regeneration CR—in stands up to 24cm dbh and at least 16m 2 /h BA R—during early thinnings or anytime when there is a high proportion of unhealthy stems R—especially in polewood stands R—especially in young plantations or ones with considerable health or form issues (i.e., weevil damage) Forest Harvesting 47
