Relationship Between Diameter Breast High And Diameter Near Ground Line For Hardwood Species In Arkansas, Richard A. Kluender, Jimmie L. Yeiser

Journal of the Arkansas Academy of Science

The relationship of diameter breast high (DBH) and diameter near ground line (DNG) was investigated for three groups of Arkansas hardwoods from four physiographic regions in the state. The relationship between DBH and DNG did not vary significantly across species groups or physiographic regions. Equations of both linear and non-linear form were developed to estimate DBH from DNG. The relationships between DBH and DNG is used to estimate timber volume, growth, and value from residual stumps. The relationship is also useful in harvesting system design and cost estimation in operational forestry.

Mountain Pine Beetle Outbreaks In The Rocky Mountains: Effects On Fuels And Fire In Lodgepole Pine Forest (Abstract), W H. Romme, D H. Knight, J Fedders

The Bark Beetles, Fuels, and Fire Bibliography

Changes in fuels were studied in northwestern Wyoming by sampling a sequence of ten stands that had been heavily damaged by beetles from 1 to 20 years earlier. Leaf litter increased only slightly (3-6%) for six years, and large woody fuels (which contribute much less to flammability) increased steadily and substantially (up to 16 x) for at least 20 years. Other fuel categories did not change significantly. While flammability may be increased during the first year or two after a beetle infestation because dead leaves are still on the trees, the risk of destructive fire during years 2-20 may be …

Woody Vegetation Of The Crystal Mountains Region, Derwood Mayo, P. L. Raines

Journal of the Arkansas Academy of Science

Arms-length rectangle transects and nested quadrats were used to sample overstory, understory and shrub layers on south-facing mountains, north-facing mountains and flat areas along Collier and Montgomery Creeks in Montgomery County, Arkansas. Data were collected and used to calculate importance values for trees and density values for shrubs. These data indicate that the shortleaf pine-oak forest type occurs on south-facing mountains while variants of white oak-black oak-northern red oak type occur on north-facing mountains and flat areas. Beech (Fagus grandifolia Var. caroliniana [Loud.] Fern and Rehd.) is common along Collier Creek and is completely absent from Montgomery Creek watershed. The …

Promoting Soft Mast For Wildlife In Intensively Managed Forests, John J. Stransky, John H. Roese

Faculty Publications

The fruit of woody plants is important as food for wildlife (Martin et al. 1951, Lay 1965). The relation of fruit production to southern forest stand conditions has been explored in only a few studies. Fruit production is greater in forest clearings than in closed forest stands (Lay 1966, Elalls and Alcaniz 1968). In Georgia slash pine (Pinus elliottii) plantations, fruit yields of shrubs are greatest in 4-yeas-old stands, and soil disturbance in site preparation greatly reduces fruit yields (Johnson and Landers 1978). Total fruit production is greatest in 5-year-old bedded loblolly pine (P. taeda) plantations …

Germination of wildland seeds is often dependent on proper seed collection and storage. A systematic approach to germination testing will often pinpoint the type of dormancy of seeds in wildland species and lead to germination enhancement.

Internal Filters : Prospects For Uv-Acclimation In Higher Plants, Martyn M. Caldwell, Ronald Robberecht, Stephan D. Flint

Green Canyon Environmental Research Area, Logan Utah

Wavelength-selective absorption of solar radiation within plant leaves allows penetration of visible radiation to the chloroplats, while removing much of the damaging ultraviolet-B radiation. Flavonoids are important in this wavelength-selective absorption. Induction of flavonoid synthesis by solar radiation, and specifically by UV-B radiation, is discussed as this relates to the potential acclimation of plants to enhanced solar UV-B radiation that would result from stratospheric ozone reduction.

Decay Rates And Nutrient Dynamics In Confines And Nonconfined Leaf Litter In The Great Dismal Swamp, R. Frederick K. Yates

Biological Sciences Theses & Dissertations

This study was designed to quantitatively compare decay rates and nutrient dynamics by the confined and unconfined litter techniques in a seasonally flooded swamp. In this study both methods indicated the same order of decay rates among sites (cedar>maple-gum>cypress> mixed hardwood), but the unconfined method showed faster decay rates at all sites. As in two years of previous data collection, the stands exhibiting some seasonal flooding showed greater decay rates than the mixed hardwood stand which was not inundated. Nutrient dynamics were not different between litter bag and leaf pack methods.

This study included a preliminary investigation of …

Litter Production And Nutrient Content Of Litter In The Seasonally Flooded Dismal Swamp, Marta M. Gomez

Biological Sciences Theses & Dissertations

Litter production was studied in four plant communities in the Great Dismal Swamp, Virginia, that differ primarily in species composition and flooding regime. Greatest leaf deposition occurred in the more flooded communities, maple-gum (Acer-Nyssa) with 536 g m^-2 yr^-1 and cypress (Taxodium distichum (L.) Richard) with 528 g m^-2 yr^-1, followed by the cedar (Chamaecyparis thyoides (L.) BSP) and mixed hardwood (Quercus-Acer-Nyssa-Liquidambar) communities with 506 g m^-2 yr^-1 and 455 g m^-2 yr^-1, respectively. Litter nutrient concentrations were generally higher in the cypress and maple-gum stands, indicating greater nutrient availability …

Occurrence And Characteristics Of Nonfruiting Myxobacteria Isolated From Pine Forest Soils, Paul M. Kulvi

All Master's Theses

A study was conducted to contribute to the taxonomy of the nonfruiting myxobacteria and to determine the effects of fire on the occurrence and characteristics of nonfruiting myxobacteria isolated from pine forest soil Three years after a prescribed burn, the population of nonfruiting myxobacteria was decreased in the burn site. The organisms isolated were distinct from any of the known species of nonfruiting myxobacteria, and apparently are new species.

The Allelopathic Potential Of Rhododendron Macrophyllum In A Western Cascades Clearcut, Ivan W. Clark

Dissertations and Theses

The purposes of this study were to determine if Rhododendron macrophyllum has the potential to inhibit the growth of other species through the production of water-soluble toxins which are leached out of its litter by rainfall, and to determine if this potential is realized in the field. The study was therefore composed of two part: 1) a series of bioassays to determine the presence an activity of water-soluble phytotoxins in R. macrophyllum leaf litter, and 2) a field study to describe vegetational patterns associated with R. macrophyllum in a western Cascades clearcut.

Biological Sciences Theses & Dissertations

The herbaceous layer of an Atlantic white cedar (Chamaecyparis thyoides) stand in the Great Dismal Swamp was sampled to estimate the productivity of two burned areas and a control area. The herbaceous vegetation was sampled along three transects utilizing the harvest method and productivity values were estimated using peak biomass values for each individual species. The burned-cut area had the highest productivity (3623 kg ha^-l yr^-1) and was characterized by species of the Asteraceae, Poaceae, and Cyperaceae. The burned-uncut area had a productivity value of 1636 kg ha^-1 yr^-1 with similar species of the Asteraceae …

Key To The Wood-Decaying Polyporaceae Of The East Texas Region, Steve Bishop, W. T. Mcgrath

eBooks

The family includes those pore fungi whose fruiting bodies are tough, leathery or woody and whose pore layer usually cannot be separated easily from the context. The pores on the undersurface are only exterior openings of tubes bearing spores and in each species these tube mouths, or pores, are a definite shape and size. Occasionally pore walls will break up giving the appearance of teeth or gills. Fruiting bodies can be sessile, stemmed, effused-reflexed or resupinate (Fig . 2). Members of the family can be either perennial or annual, with the annual species growing during the summer and maturing that …

Optical Management Of The Spruce-Fir Forest Against The Spruce Budworm, Gari B. Simon

Senior Scholar Papers

Proper management of the softwood forest-budworm ecosystem is vital to the future prosperity of Maine. In choosing a management strategy, economic as well as ecological effects must be considered. This paper constructs a computer simulation model of the budworm-forest ecosystem in order to better evaluate effects of different types of forest management. The budworm-softwood forest ecosystem is a highly complicated system involving three dynamic population systems: the host tree population, the budworm population and the foliage population. Each system is modeled, by regression analysis, to observations collected by entomologists over the past half century. There are large gaps of knowledge …

Studies On The Causes Of Tree Distribution In A Forest Type In The Dismal Swamp National Wildlife Refuge, Thomas A. Janszen

Biological Sciences Theses & Dissertations

Vegetational composition and environmental parameters were analyzed in a forest type of the Dismal Swamp. A 0.5 ha forest stand was divided into 200 5 x 5 meter contiguous quadrats and the tree size classes were precisely mapped. Fifty soil samples were analyzed for texture, pH, and major nutrients. A topographic map was constructed with precision to 0.01 ft. Analysis of variance tests showed non-randomness to exist in soil texture and nutrient content while homogeneity tests showed non-randomness in distribution of some woody species. Factor analysis indicated no significant correlations between soil quality, topography, and woody species. Findings indicate that …

Wildlife Habitats In Managed Rangelands-- The Great Basin Of Southeastern Oregon, Wayne Bowers, Bill Hosford, Art Oakley, Carl Bond

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

All land management activities on managed rangelands will have some impact(s) on fish habitat; those in the riparian zone will have the greatest impact(s). Native trout populations in the Great Basin of southeastern Oregon exhibit predictable responses to alterations in their habitats; optimum production of native trout is therefore achievable through careful habitat management.

Mutual Exclusion Between Salmonberry And Douglas-Fir In The Coast Range Of Oregon, Kenneth Ray Still

Dissertations and Theses

One serious problem faced by the forest industry in the Pacific Northwest is poor regeneration of commercial trees on land which is harvested and subsequently dominated by brush species. In Coastal Oregon, salmonberry is one of these brush species. Detailed investigations of field sites indicate that light intensity in the brush stands was low but sufficient for germination and early growth of Douglas-fir seedlings and soil moisture percentages and nutrient levels were high enough to support early Douglas-fir growth. Laboratory tests demonstrated the presence of leachable phytotoxins in the leaves of salmonberry. The hypothesis resulting from this study is that …
