1 Shelterwood

2 Regeneration cut Modify environment of regen Provide seed source

3 Even-age regeneration Length of regeneration time varies by circumstance

4 Process Create available growing space for regen –Removal of part of the overstory Remove remaining overstory before growth of regen is overly inhibited

5 Stages Prep cut(s) Final removal

6 Difference from Thinning Purpose is regeneration Main objective is not future growth of residual stand –Can be secondary objective

7 Usually for natural regeneration Can be supplemented with planting –Species –More uniform stocking

8 Classic 3-cut Shelterwood

9 Money Upfront

10 Irregular shelterwood

11 Strip shelterwood

12 One cut shelterwood

15 Framework Age structure Species composition Disturbance regime

16 Yield Growth of regen Growth of remaining overstory

17 Possibility of carrying some trees into next rotation Not part of “shelterwood” per se A variation worth considering Turns a single cohort stand into a two cohort stand

19 Veg Management Difficult Major problem if competition is more shade tolerant than the desired species

20

21 Logging equipment Almost anything can be used Cable on steep slopes can be difficult

24 Cost Can be lowest cost Two or more harvests –Increased growth of overstory –Regen can be cheap

25 Aesthetically desirable Continuous green cover
