Coniferous Forest Habitat Types Of Northern Utah, U.S. Forest Service, United States Department Of Agriculture, Ronald L. Mauk, Jan A. Henderson

All U.S. Government Documents (Utah Regional Depository)

A habitat type classification is presented for the coniferous forests of northern utah and adjacent areas of idaho and wyoming. The classification and descriptions are based on data from about 1,100 sample stands covering 6 years of reconnaissance sampling.

Streamflow Summaries From Twelve Tributaries Of Farmington Creek, Davis County Experimental Watershed, Northern Utah, U.S. Forest Service, United States Department Of Agriculture, Jan M. Pankey, Norbert V. Debyle

All U.S. Government Documents (Utah Regional Depository)

The Farmington Creek watershed consists of 6,400 acres of forested and brush-covered lands on the west face of the Wasatch Mountains between Salt Lake City and Ogden. Streamflow data have been gathered from this stream as well as from most of its perennial tributaries for many years. Mean daily, monthly, and annual flows are tabulated for all years of record from the 12 gaged tributaries of farmington creek.

Increasing public awareness about the state of forestry and concerns about present and future wood supplies are bringing about an intensification of forest management across the country.

Coniferous Forest Habitat Types Of Northern Utah, Ronald L. Mauk, Jan A. Henderson

The Bark Beetles, Fuels, and Fire Bibliography

Data from >1100 plots in coniferous forests of northern Utah and adjacent areas of Idaho and Wyoming were used to identify 8 climax series and 36 habitat types. Descriptions are given of each type with notes on potential productivity for timber and characteristics of site, climate and surface soil.

The Impact Of Nitrification On Soil Acidification And Cation Leaching In A Red Alder Ecosystem, H. Van Miegroet, D. W. Cole

Watershed Sciences Faculty Publications

The objectives of this study were to investigate the impacts of internal nitrification on soil and soil solution acidity and on the rate of nutrient export through NO3– mediated leaching. This was achieved by comparing soil chemical properties and soil solution composition within a naturally N-rich red alder (Alnus rubra Bong.) ecosystem to those of an adjacent Douglas-fir [Pseudotsuga menziesil (Mirbel) Franco] forest where soil N levels were significantly lower and no measurable HNO3 production could be observed. In the red alder system, where > 100 kg ha–1 yr–1 of N were added through symbiotic N2 fixation, the net annual NO3– …

Asexual Vs. Sexual Propagation Of Quaking Aspen, Robert B. Campbell Jr.

Aspen Bibliography

ABSTRACT: Quaking aspen (Populus tremuloides Michx.)

regenerates almost exclusively by root suckers in the

western United States, even though female clones

produce abundant viable seed. During the past decade,

interest in propagating aspen for use as an

ornamental and for revegetation of forest land has

increased. To satisfy these diverse needs for aspen

planting stock, nurserymen have a choice between

sexual and asexual propagation. Criteria for clone

selection, suggestions for root and seed collection

and storage, propagation techniques, and the

advantages of both sexual and asexual propagation are

discussed.

Whole Stand Volume Tables For Quaking Aspen [Populus Tremuloides] In The Rocky Mountains [Colorado, Wyoming], Wayne D. Shepperd, H.T. Mowrer

Aspen Bibliography

Linear regression equations were developed to predict stand volumes for aspen given average stand basal area and average stand height. Tables constructed from these equations allow easy field estimation of gross merchantable cubic and board foot Scribner Rules per acre, and cubic meters per hectare using simple prism cruise data.

A Method For Describing Equilibrium Moisture Content Of Forest Fuels, R.M. Nelson, Jr.

Aspen Bibliography

The isothermal adsorption and desorption of water vapor by forest fuels is represented with a two-parameter model based on an exponential relationship between Gibbs free energy change and equilibrium moisture content. The model is applied to five sets of sorption data in the literature to illustrate goodness of fit. Two of the data sets are well reproduced by the model; description of the remaining data is less satisfactory. Whether the deviations are due to experimental factors or a deficiency in the model is not determined. At constant temperature, hysteresis ratios tend to increase as percent relative humidity increases.
