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 present day vegetation pattern of the Willamette Valley is a result of a long past of human alteration of the landscape. Beginning with aboriginal burning of the grasslands to present day land uses, the vegetation of the valley has been affected by anthropogenic activity. Wet prairie is a vanishing...
Annual flood damages continue to rise in the United
States in spite of massive investments in flood control structures
since 1936. These increased losses can be attributed, in part,
to the inherent Limitations in scope and nature of traditional
"structural" approaches to flood control. Acquisition of flood
plain lands is...
Forest management is an important mechanism that provides social, ecological, and economic benefits to the community. On public lands, management is often initiated for multi-use objectives. However, both history and research have proven that the level of acceptance for harvesting on public lands varies both temporally and spatially. Public perceptions...
This project aims to study the performance of Secure Sockets Layer (SSL) Protocol implemented in JAVA for web applications. Secure Sockets Layer protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. In particular, this project focuses on an implementation of...
The boreal forest zone is located in the cool, high latitudes of the earth and represents approximately one third of the world’s remaining forested area. Maintaining the functional capacity of boreal forests is of global importance as they will both affect and be affected by climate change. Boreal forests can...
An automated library system should be capable of providing at least all of the information and capabilities of existing manual catalogs. In addition, an automated system must provide the capability of manipulating that information to produce varying types of reports and statistics. This paper briefly:
- describes historical representations of...
Congress created the Collaborative Forest Landscape Restoration Program (CFLRP) in 2009 with the passage of the Forest Landscape Restoration Act (Omnibus Public Lands Management Act of 2009 Title IV). The purpose of the CFLRP legislation is to implement forest restoration work on national forest lands through a competitive grant program....
This paper includes a literature review of the methodologies invoked to surmount difficulties inherent with aerial photograph mensuration. The synopsis of early achievements is followed by a more intensive examination of experimental studies of the last decade, particularly the work on controlled scale photography.
This report on the pursuit of...
Mean annual runoff to precipitation (R/P) ratios were generated for 966 watersheds within the contiguous United States. The watersheds were plotted using Arc View GIS and used as part of an overlay analysis with Level 1 U.S. ecoregions. The ratios were statistically evaluated to determine anomalous R/P conditions within the...
