For jack pine (Pinus banksiana), the rates of photosynthesis varied among provenances according to the time of year (35). Differences in rates also were observed in Scotch pine (Pinus sylvestris) from Poland and from Turkey (2). In Douglas-fir; rapid growth appeared to be related more to photosynthetic area than to efficiency of the foliage (18). No category; Wildland Fire in Ecosystems Effects of Fire on Flora.

After the first year, the plant biomass in early-grazed plots consisted of 29% aspen and 28% grass (mainly sown species), while late-grazed plots had only % aspen and 18% grass, with a higher proportion of shrubs, especially snowberry. Trends established after the first year were still evident after the second year.

Deerbrush sprouts from the root crown after fire, but sprouting response may be weak [21,42].Sprouts on older plants have died in their first year even when watered in summer (Howard personal observation ).Park records from Sequoia-Kings Canyon National Park note numerous sites where deerbrush seedlings occurred after fire, but only two sites where sprouts were found after fire.
Douglas-fir. After 2 years, the 2+0 bareroot pine were significantly larger in volume than the 2+0 bareroot Douglas-fir despi te a smaller starting size. Their relative growth was greater than that of the Douglas -fir stock types in diameter, height, and volume for and Similarly, the 1 +0 plug pine tended to grow faster than the 1.

For. Ecol. Manage., 5: A ha area in the central California Sierra was harvested in to provide three shelterwoods with residual basal areas of 10, 15, and 20 m2/ha.

A revealing example is pictured in plate 76 where the influence of an wildfire in Douglas-fir was still evidenced in by the predominance of shrubs. In Douglas-fir habitat types of the Inter- mountain region, fires favor shrubs, and they may dominate seral communities for.
Advance regeneration 50 to 60 years old commonly develops into a vigorous, physiologically young-growth stand after complete removal of the overstory; however, poor response to release has been noted for suppressed trees over years old.
Pseudotsuga menziesii var. glauca (Mayr) Franco NRCS PLANT CODE: PSMEG COMMON NAMES: Rocky Mountain Douglas-fir Younger trees' growth rates are more responsive to release from competition; in central Idaho, Rocky Mountain Douglas-fir shorter than 20 feet Rocky Mountain Douglas-fir's response was less positive than that of western larch.
The subject of fire as an ecological factor is an exceedingly broad and complex one. The forest soil of the Douglas fir region and the changes wrought upon it by logging and slash burning.

While this is an extremely high rate, consider the application of ammonium nitrate at percent first year release, which would supply lb/ac (Line A) of immediately available nitrogen. Creeping Thistle.
That book was "The Phantom Ghost of Harriet Lou" [subtitled "And Other Elk Stories"]. I've since read the book three times, certain chapters many more times, and both of your books on grizzlies. I have decided to stay in Montana for schooling and plan on making a career working with the land.
Burned areas included 2 old-growth ponderosa pine-Douglas-fir stands on southeastern and southwestern aspects and 2 shrubland habitats dominated by mallow ninebark, snowbrush ceanothus, Saskatoon serviceberry, chokecherry, and bitter cherry (Prunus emarginata) on southeastern and west-southwestern aspects.
Height models for juvenile even aged mixed-species stands were developed for locations near Nelson, British Columbia.
Separate models were developed for each conifer species found, as well as for paper birch (Betula papyrifera). The objectives were to develop models for: 1) the number of years to reach breast height; 2) height achieved at a given age above breast height (height yield); 3.
