A review of the literature has shown that no one concise and consistently successful method has been developed for regenerating Quercus rubra throughout its range (Marquis, et al, 1976;Loftis, 1983;Johnson, 1981;Johnson, et al, 1989;Potter, 1991;Schultz and Thompson, 1991).…”

“…Sander (1977) recommends estabUshing Quercus regeneration by using the shelterwood system in which stands are 60 percent stocked. Johnson (1981) and Johnson, et al (1989) have reported that Quercus can be successfully regenerated in clearcuts.

“…Minter, et al (1992) concluded that tree shelters promote increased height growth by increasing relative humidity, reducing plant transpiration losses, and increasing levels of 002-This height growth comes at the expense of diameter growth. Johnson, et al (1989) have shown that clearcutting with herbicide control of competition may be the key to regenerating Quercus rubra in southwestern Wiscoixsin. They reported a case in southwest Wisconsin in which the understory of a mature stand was treated with 2,4,5-T in the two years prior to clearcutting.…”

Five-year survival and growth of northern red oak (Quercus rubra L) seedlings in upland hardwood stands in south central Iowa

A msgor concern in the management of Quercus rubra is the difficulty in regenerating stands that have developed dense understories of shade tolerant species. A study was conducted at two locations in south central Iowa to determine the impact over a five year period of using root graded seedlings, understory control, tree .welters, and overstory reduction on establishing imderplanted, 1-0, Quercus rubra bare root stock. Relationships between growth or mortality, and photosynthetically active radiation, red to far red light ratio, basal area, average stand diameter, nimiber of trees/hectare, percent stocking, and varioiis combinations of these variables were tested. Shelters and root grading had the greatest impact on survival and growth of the underplanted seedlings. Annual survival and growth of non-sheltered seedlings was greater than sheltered seedlings after three growing seasons. However, By the end of the fifth growing season non-sheltered seedlings had averaged 221 percent greater growth and 75 percent greater survival than sheltered seedlings. Underplanted seedlings with five or more permanent, first-order, lateral roots had 93 percent greater growth at the McNay site and 407 percent at the Stephens sites, respectively, compared to seedlings with fewer, first-order, lateral roots. R-square relationships between growth or mortality, and photosynthetically active radiation, red to far red light ratio, basal area, average stand diameter, niimber of trees/hectare, percent stocking, and various combinations ranged from 0.00 to 0.66. Spraying and mechanical clearing of the understory prior to underplanting helped underplanted seedlings maintaining a competitive position in the understory. Based on the literature and the results of this study resource managera should: (i) reduce overstory stocking to approximately 60 percent; (ii) use herbicide or V mechazucal methods to reduce understory competition; (iii) plant bare root stock with five or more permanent, first-order, lateral roots; and (iv) remove the remaining overstory when the underplanted Quercus rubra seedlings are 1.5 m in height in order to aid in the regeneration of Quercus rubra in south central Iowa.

Determining the location of a deceased mother tree and estimating forest regeneration variables by use of microsatellites and spatial genetic models

et al. 2007

In this paper we first mathematically formulate spatial genetic models that rely on dispersal kernels, using the genetic inhomogeneous Poisson process. On the basis of mapped and genotyped data pertaining to adult and juvenile trees we are able to estimate three fundamental variables of population dynamics: individual female reproductive success, seed dispersal, and pollen flow. The model was applied to a secondary Fagus crenata stand in northern Japan, regenerated after shelterwood harvesting. Highly polymorphic microsatellite data revealed that most of the juveniles around one adult tree were not that tree's progeny and that some minor alleles were clustered there. These data suggested that another mother tree had formerly been present in the vicinity, produced offspring there and died. Inferring its genotype and location, we applied the genetic inhomogeneous Poisson process. Results confirmed that we would have wrongly assessed the regeneration if we had been unaware of the existence of the dead mother. The average distances for seed dispersal and pollen flow were 18 and 193 m, respectively. The contribution of outside mothers, simultaneously assessed using the dispersal variables in the models, ranged from 10 to 50% depending on their positions relative to preserved adults. Individual female reproductive success varied as much as fiftyfold among the eight preserved adults. Our comprehensive approach, utilizing currently available genetic information, mathematical models, and previous forestry records, helped elucidation of the past forest‐regeneration processes.
