sprouts and shade-tolerant shrubs grow out over the 

 slash and are rapidly covered with vines to form a vir- 

 tually impenetrable mass. 



6.3.4 Propagation 



From seed . The USDA recommends 

 pretreatment of cones for extraction of seed (Harris 

 1974) and placement of seeds in sealed containers 

 if storage is necessary. Stratification (exposure of 

 seeds to a moisture and temperature regimen) is 

 believed to stimulate prompt seed germination, but 

 optimal nursery practice has not yet been defined ex- 

 perimentally for the species (Harris 1 974). Fall plant- 

 ing of seed is recommended in New Jersey (Little 

 1950). 



From cutting s. A protocol for propagation 

 by cuttings recommended by T. Dilatush (pers. 

 comm.) follows: 



Take cuttings in late autumn. Place in a half 

 peat/half sand growing medium, 20 cm deep, over a 

 relatively poor-percolation clay base, in board-sided 

 beds. After 2 years, most seedlings are 30-45 cm. 

 Cut from the bed in 20 cm soil squares. These 

 transplant well into a rototilled sand/peat/clay 

 "veneer" layer of improved soil over relatively imper- 

 vious clay, with periodic sprinkling. Some clones 

 have considerably more rootmass than others. In 

 general, better rooted clones provide more height 

 and girth in a shorter time. 



Dilatush noted signs of winter stress on the 

 faces of trees along road cuts through monotypic 

 cedar stands following severe winters for many years 

 after the original roadcut. Populations similarly ex- 

 posed in the untouched forest, such as along the 

 river edge face of a monotypic stand, do not appear
