This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of graduate students in the sciences preparing for careers in academia has long included elements to advance students as science researchers, but recent emphasis is being placed on developing students as instructors and education researchers as well. As such, objectives of this study included assessments of seedling responses to hydrology typical of floods in urban settings, the role of created microtopography in community development of a bottomland hardwood forest, and the influence of geographic information systems (GIS) on student motivation and conceptual knowledge. Substantial losses of bottomlands in Texas necessitate restoration to regain the ecosystem services that they provide. Restoration of proper hydrology is the most important aspect of wetland restoration, but this can prove difficult in urbanizing environments where hydrology has been irreversibly altered. Microtopography has been shown to be an important component of bottomland hardwood forests, and its restoration may aid in hydrologic restoration as gradients are created that support a diverse community. Tree seedlings were subjected to experimental flooding regimes typical of floodplain forests in rural and urban settings. Growth rates of seedlings varied over time and differed depending on species and treatment. Created microtopography resulted in a spatially heterogeneous system similar to that of natural bottomlands and strongly influenced hydrology, soil properties, survival of planted seedlings, and abundance and distribution of colonizing species. Proper bottomland restoration in urbanizing environments should include species selection based on current and potential future hydrologic conditions. In addition, restoring microtopography may improve survival of a variety of species introduced during restoration, as well as enhance colonization of a diverse plant community under changing hydrologic regimes. Trends indicated a slight improvement in attitude and performance for students that used GIS. More important, the authenticity of the experience appeared to affect student attitude. The effective use of GIS in teaching may be scale-dependent. Smallscale phenomena may be assessed as easily in a field exercise as with GIS. Using GIS to assess large-scale, complex patterns may have a substantial impact on student understanding. Further studies are needed to determine direct benefits of teaching with GIS in undergraduate ecology classrooms.

Williams and published by . This book was released on 2010 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Management of forest ecosystems, such as dry forests of the western U.S., can be enhanced by knowledge of the historical spatial structure across large landscapes. Historical information about forest structure before widespread Euro-American land uses is often limited to a few small remnant patches, but one source, the General Land Office (GLO) survey, has potential for systematic information across large land areas. The surveys, largely completed in the mid- to late-1800s in the West, recorded information on trees at surveyed corners, including tree species, size and distance from the corner. However, there are limitations to using GLO survey data that need to be addressed before widespread reconstructions can be performed. Limitations include potential selection bias, unknown accuracy of surveyor measurements, potential recording errors, and unknown accuracy of survey reconstruction methods. Bias and accuracy of survey methods were assessed in three landscapes: the Mogollon Plateau, Arizona, the Front Range, Colorado, and the Blue Mountains, Oregon. A fourth landscape, Black Mesa, Arizona, was added for reconstructions. Accuracy of survey reconstruction methods was assessed by comparing modern survey data with plots (considered truth) at the same location in a sampling grid replicating the sampling intensity of the surveys. Surveyor selection bias, measurement accuracy and recording errors were assessed by directly observing the location of historical trees at survey corners, remeasuring surveyor measurements and reconstructing tree diameters by extracting tree cores. I found that surveyors selected the closest tree to the corner 95 to 98% of the time; thus, selection bias was low. Most trees selected against were
Book Synopsis Forest and Wildlife Habitat Analysis Using Remote Sensing and Geographic Information Systems by : Maria R. Fiorella
Download or read book Forest and Wildlife Habitat Analysis Using Remote Sensing and Geographic Information Systems written by Maria R. Fiorella and published by . This book was released on 1992 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest and wildlife habitat analyses were conducted at the H.J. Andrews Experimental Forest in the Central Cascade Mountains of Oregon using remotely sensed data and a geographic information system (GIS). Landsat Thematic Mapper(TM) data were used to determine forest successional stages, and to analyze the structure of both old and young conifer forests. Two successional stage maps were developed. One was developed from six TM spectral bands alone, and the second was developed from six TM spectral bands and a relative sun incidence band. Including the sun incidence band in the classification improved the mapping accuracy in the two youngest successional stages, but did not improve overall accuracy or accuracy of the two oldest successional stages. Mean spectral values for old-growth and mature stands were compared in seven TM bands and seven band transformations. Differences between mature and old-growth successional stages were greatest for the band ratio of TM 4/5 (P = 0.00005) and the multiband transformation of wetness (P = 0.00003). The age of young conifer stands had the highest correlation to TM 4/5 values (r = 0.9559) of any of the TM band or band transformations used. TM 4/5 ratio values of poorly regenerated conifer stands were significantly different from well regenerated conifer stands after age 15 (P = 0.0000). TM 4/5 was named a "Successional Stage Index" (SSI) because of its ability to distinguish forest successional stages. The forest successional stage map was used as input into a vertebrate richness model using GIS. The three variables of 1) successional stage, 2) elevation, and 3) site moisture were used in the GIS to predict the spatial occurrence of small mammal, amphibian, and reptile species based on primary and secondary habitat requirements. These occurrence or habitat maps were overlayed to tally the predicted number of vertebrate at any given point in the study area. Overall, sixty-three and sixty-seven percent of the model predictions for vertebrate occurrence matched the vertebrates that were trapped in the field in eight forested stands. Of the three model variables, site moisture appeared to have the greatest influence on the pattern of high vertebrate richness in all vertebrate classes.
Book Synopsis Forest Landscape Assessment Tool (FLAT) by : Lisa Anne Ciecko
Download or read book Forest Landscape Assessment Tool (FLAT) written by Lisa Anne Ciecko and published by . This book was released on 2016 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Forest Landscape Assessment Tool (FLAT) is a set of procedures and tools used to rapidly determine forest ecological conditions and potential threats. FLAT enables planners and managers to understand baseline conditions, determine and prioritize restoration needs across a landscape system, and conduct ongoing monitoring to achieve land management goals. The rapid assessment process presents a cost-effective opportunity for landowners that include local governments, private owners, and nongovernmental organizations to use ecological data to guide decisionmaking and improve environmental outcomes on their lands. This report is an introduction to FLAT, providing an overview of its purpose, methods, and implications for land management in diverse regions. FLAT is executed in three sequential phases: Phase 1--Forest Cover Type Mapping, Phase 2--Field Assessment, and Phase 3--Management Prioritization. Overall, FLAT consists of onsite visual estimation (aided by remote sensing) of ecological conditions by a trained field team to produce a forest inventory. In addition to providing baseline data and a framework to prioritize actions, FLAT can be used as a monitoring tool to evaluate changing conditions and inform adjustments in management strategies and priorities. To illustrate FLAT implementation, the King County Department of Natural Resources and Parks case study details a pilot project conducted on 24,700 of the more than 26,000 ac of county lands. King County is using the results from FLAT to develop and implement forest stewardship plans and target efforts of its volunteer restoration program. Although the tool was initially used in lowland forests in the Puget Sound region, in concept, FLAT could be expanded and adapted for use in a wide variety of ecosystem types."--Abstract

This book was released on 1992 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1991, the development of a spatial forest data base over most of the Great Lakes-St. Lawrence Region was commissioned to provide the thematic basis for studies conducted for the forest fragmentation and biodiversity project under the forest landscape ecology program. The data base included a range of forest and vegetation cover classes, with the red pine and white pine stands restricted to those over 50 years of age. A method combining remote sensing and geographic information system technology was used for the project. This report describes the approach and method of the project as a whole and includes a summary of Phase I and more detailed information on Phase 2.

Book Synopsis Application of a Digital Terrain Model for Forrest Land Classification and Soil Survey by : Christopher J. Fabian

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Land characterization and classification is central to sound natural resource management. Forest land classifications usually lack sufficient detail, are not scale-adjustable, and are limited in scope and applications for the spectrum of relevant management decisions. Two alternatives for forest land classification have been proposed: a multifactor ecological land classification system (ECS) and a soil survey approach that is more geomorphic-based, comprehensive and forestry oriented than traditional classifications. Landforms influence important site factors, are easily observable features, and are relatively stabile in the landscape, so are a logical base for land classification systems. Geographic Information Systems (GIS) was used with Digital Elevation Models (DEM's) to produce Digital Terrain Models (DTM's) in the Missouri Ozarks. Terrain models produced from several DEM sources were evaluated for their accuracy in predicting slope, aspect and landforms on a 3691 ha area. The DEM's created from USGS hypsography were most accurate. Slope classes were correctly identified in 71.6% and aspect classes in 84.6% of observations. A rule-based approach to classifying landforms agreed with a field survey on 71.2% of the calibration site and 64.3% of the test site. A soil-geomorphic ecological approach using terrain modeling proved to be an accurate, consistent, efficient and cost-effective method.
