Zimbabwe's Communal Areas Management Program For Indigenous
Resources (CAMPFIRE), is a grassroots natural resource management
initiative that promotes utilization of natural resources as an
economic and sustainable land use option in Zimbabwe's rural areas.
Currently the program focuses on wildlife utilization as a
development intervention to improve the economic livelihood...
Large woody debris (LWD) consists of boles, root wads and large branches that
enter the stream through a variety of processes including senescence, wind throw, bank
failure, fire, and debris torrents brought on by flood events. Within the stream, LWD
provides significant benefits to aquatic organisms by contributing nutrients, providing...
Nine west-northwest-trending faults on the continental margin of
Oregon and Washington, between 43° 05'N and 470 20'N latitude, have been
mapped using seismic reflection, sidescan sonar, submersibles, and swath
bathymetry. Five of these oblique faults are found on both the Juan de Fuca
and North American plates, and offset abyssal...
Vegetation along the banks of mountain streams in the western Oregon
Cascades comprises an integral part of the transition zone between land and
water based ecosystems, and as such, is a vitally important and unique natural
resource. Forestry is a major land use in this region, and harvesting riparian
vegetation...
Benton County, Oregon has been experiencing relatively high growth and
development during the last five years. This new growth has put a strain on urban and
rural development in the county. To cope with this growth, comprehensive plans,
zoning, and many other planning issues must be assessed and revised according...
During the Cenozoic, tectonics in the Cuyama basin of the southeastern Salinian block changed from extension to strike-slip faulting to compression and rotation. During the Oligocene-early Miocene, the Cuyama basin was adjacent to the southern Mojave region and part of that extensional tectonic regime. Many present-day reverse faults have an...
The Juniper Ridge volcanic complex is located in the High Lava Plains Province of
southeastern Oregon, a wide zone of bimodal volcanism and faulting that marks the northern
limit of widespread Basin and Range-style faulting in the northern Great Basin Province. Rhyolite
dome complexes are progressively younger to the northwest...
This study assessed how logging-access roads may have contributed to
observed historical increases in peak discharges associated with small and large
logged basins in the western Cascades of Oregon. The study was conducted on
the Lookout Creek (62km²) and the upper Blue River (118km²) basins. Potential
road effects on hydrology...
This study was conducted to test a photographic method of determining the
relationship, if any, between the spectral reflectance and measured levels of nitrogen and
chlorophyll in plots of ryegrass turf. Color and color infrared aerial photos were taken of a
grid of 375 plots of ryegrass in June and...
The old-growth forest conflict is part of the evolving debate over how to use the federal
public lands. This study documents the origins and development of the old-growth issue through
1989. The controversy began in the early 1970s when scientists initiated studies of old-growth
forests and northern spotted owls, and...
Detailed subsurface structure contour maps and cross sections have shown the
northern Los Angeles basin to be underlain by a south facing monocline that is
complicated by secondary faults and folds. The monocline forms a structural shelf that
marks the northern boundary of the Los Angeles central trough. The monocline...
Sediment production and delivery in Pacific Northwest
coastal streams can have damaging effects on channel
morphology and anadromous fish habitat. The research in
Pistol River was designed to determine if a link exists
between sediment delivery processes and degradation of fish
habitat. Objectives of this basin-wide analysis were to:
1)...
This paper explores the use of hypermedia m geographical and environmental analysis, focusing on the use of sound. After providing essential definitions the paper presents a brief history of multimedia and hypertext (the combination of which lead to the term hypermedia) and object oriented programming. The concept of the hypermap...
The northern Los Angeles basin is influenced by two structural styles: the west-trending compressional Transverse Ranges to the north, and the strike-slip Peninsular Ranges to the south. The interaction of these two structural styles has resulted in a complex fold fault belt at the northern margin of the Los Angeles...
The Calvin impact crater is an isolated, nearly circular subsurface structure of Late
Ordovician age in southwestern Michigan. The crater is defined by 110 on and gas test wells, has a rim to rim diameter of 6.2 km, an overall dimensional diameter of 8.5 km and
consists of a central...
The key to developing successful environmental interpretation is sound
planning. This paper is a discussion of the principles of environmental interpretation
and how they apply to the planning process. The Coburg Wetland is a 21 acre
reserve located on the west side of lnterstate-5 in Coburg, Oregon. The city of...
The pattern of ownership imposed on the-forest landscape of Western
Oregon defines the boundaries in which differences in jurisdiction, regulation, and
land use operate. Road building is controlled by these factors, and in turn has an
effect on the cumulative effects of human utilization of the forest. This study
examined...
Three-dimensional gravity analysis is the process of removing the predictable
components from the free-air gravity anomalies and has proven to be useful for
interpreting the subsurface structures and active processes at mid-ocean ridges. The
three-dimensional effects of the seafloor and Moho topography, assuming a constant
crustal thickness and constant crust...
The Rattlesnake Ash-Flow Tuff erupted 7.05±0.01 Ma from the western Harney Basin, southeastern Oregon. The location of the vent area is inferred based on vent-ward increases in size of pumices, in degree of welding, and in degree of post-emplacement crystallization. Today's outcrops cover 9000 km2 and estimated original outcrop coverage...
