50. Regeneration Terminology Even-aged Methods Two-aged Methods Uneven-aged Methods

51. Smith (1962) Any classification of methods of reproduction is merely a device for systematizing description of the wide variety of procedures which have been used in practice. Development of methods effective in specific situations comes first in both time and importance; the classification of these methods comes afterwards.

52. Regeneration Methods Even-aged Even-aged -Clearcutting Method -Shelterwood Method Two-aged Uneven-aged Uneven-aged -Group selection -Single tree selection

53. Even-aged methods Methods that regenerate and maintain a stand with a single age class

54. Even-aged Methods Clearcutting Method Shelterwood Method

55. Clearcutting Method The cutting of essentially all trees, producing a fully-exposed microclimate for the development of a new age class

57. Seed Tree Method The cutting of all trees except for a small number of widely dispersed trees retained for seed production and to produce a new age class in a fully exposed microenvironment.

58. Shelterwood Method The cutting of most trees, leaving those needed to produce sufficient shade to produce a new age class in a moderated microenvironment---the sequence of treatments can include (a) preparatory cut, (b) establishment cut, (c) removal cut

60. Oak Shelterwood Method Before treatment 1 year after treatment 10 years after treatment

61. Two-aged Methods Methods that regenerate and maintain stands with two age classes. The resulting stand may be two-aged or tend toward an uneven-aged condition as a consequence of both an extended period of regeneration and the retention of reserve trees that may represent one or more age classes.

62. Two-aged Methods Clearcutting with reserves Shelterwood with reserves

63. Clearcutting with reserves Clearcutting in which varying numbers of reserve trees are not harvested to attain goals other than regeneration.

64. Shelterwood with reserves Some or all of the shelter trees are retained after regeneration has become established to attain goals other than regeneration

65. 20 ft 2 /ac Two-aged Method

66. Uneven-aged (selection) Methods Methods that regenerate and maintain a multi-aged structure by removing some trees in all size classes either singly, in small groups, or in strips

67. Group selection Trees are removed and new age classes are established in small groups. The width of the groups is commonly approximately twice the height of the mature trees

69. Group selection with reserves Some trees within the group are not cut to attain goals other than regeneration

70. Single tree selection Individual trees of all size classes are removed more or less uniformly throughout the stand, to promote growth of remaining trees and to provide space for regeneration
