37 Seeing The Forest Beyond The Trees Basic Stocking and Yield Relative Yield Stocking

38 Seeing The Forest Beyond The Trees Elements of Regeneration Stocking Basic Are there enough trees to occupy all of the available growing space? Enhanced Is the growing space allocated in a manner that we will achieve our desired future forest condition?

39 Seeing The Forest Beyond The Trees Allocation of Growing Space - a simple case -

40 Seeing The Forest Beyond The Trees Allocation of Growing Space - a more complex case - Species composition Species Intermingling Spatial Pattern Vertical Structure Scale Stand Density

41 Seeing The Forest Beyond The Trees Succession - Conifers

44 Seeing The Forest Beyond The Trees Succession - Conifers

45 Seeing The Forest Beyond The Trees Succession - Conifers

46 Seeing The Forest Beyond The Trees Succession - Mixedwoods

47 Seeing The Forest Beyond The Trees The Conifer Free-Growing Paradigm OK Not OK

48 Seeing The Forest Beyond The Trees The Conifer Free-Growing Paradigm Mixedwoods are a continuum of competitive conditions

49 Seeing The Forest Beyond The Trees New Mixedwood Paradigm for Regeneration Standards CCDDCD
