Exotic plant invasion is a major environmental and ecological concern and is a particular issue for wetland ecosystems. I present statistical models that predict the locations of three exotic invasive plants (Arundo donax, Eucalyptus species (Eucalyptus globulus, Eucalyptus calmodulensis), and Tamarix ramosissima) that invade wetland areas throughout San Diego County based on their spectral signatures. I used three images that differed in their spectral resolutions and spectral coverage: Color-infrared (1m pixel size, infrared, blue and green bands), high resolution true color imagery (lm pixel size, red, blue and green bands), and hyperspectral Landsat imagery (30m pixel size, blue, green, red, near infrared, (2), mid infrared, and thermal infrared bands). For each invasive plant, three well-known multivariate statistical analyses, Discriminant Function Analysis (D.F.A.), Quadratic Discriminant Function Analysis (Q.D.F.A.), and CART, were used to identifY the models that best separated invasive plants from surrounding vegetation. A predictive accuracy analysis was preformed for each model by predicting which points should contain the invasive species based on their spectral values, then comparing these predictions to the actual presence or absence of the species. The best model for both Arundo and Eucalyptus species was obtained from the Q.D.F.A. using spectral values calculated from a combination ofNAIP and Landsat wavebands. CART using spectral values obtained from Landsat imagery produced the best results for Tamarix. Past studies show that plant species do in fact have distinct spectral signatures however; further investigation of classification techniques for this study is needed in order to create a more successful predictive model for each invasive plant species. Key-words: Discriminant Function Analysis, CART Model, hyperspectral imagery, invasive plants, predictive model, spectral signatures.

"Great Lakes coastal wetlands are some of the most crucial ecosystems to biodiversity in the Great Lakes Basin, yet suffer increasing degradation due to invasive plants. Wetland plant invasions can be controlled in their initial stages, but early detection of invasive plants using field surveys are often untenable due to budget constraints. Remote sensing techniques offer solutions to management objectives during the early stages of invasion on a landscape scale due to their ability to cheaply create spatially explicit information about plant distributions. Some invasive plants, such as Typha x. glauca, are conspicuous on a large scale, and can be mapped to their current extent using new satellite and modeling techniques. Inconspicuous invasive plants however, such as Hydrocharis morsus-ranae, may be undetectable by remote sensing sources and require predictive strategies. In this thesis I explored the use of remote sensing in the management of a conspicuous and inconspicuous invasive wetland plants in the St. Mary's River, MI. I successfully classified the current extent of conspicuous Typha x. glauca and other wetland vegetation types to provide spatially explicit maps for early detection and management and examined methods that can be adapted for use in emergent wetlands worldwide. The habitat suitability of inconspicuous Hydrocharis morsus-ranae was also determined using novel fine-scale habitat covariates determined from lidar and radar. Habitat covariates derived from these sources should see wider use in species distribution modeling, particularly with wetland plants, to create better predictions of invasive plant expansions. Implementation of new and upcoming remote sensing data sources and methods will allow for better invasive wetland plant management at greater spatial and temporal scales than field studies alone."--Boise State University ScholarWorks.

This Open Access volume aims to methodologically improve our understanding of biodiversity by linking disciplines that incorporate remote sensing, and uniting data and perspectives in the fields of biology, landscape ecology, and geography. The book provides a framework for how biodiversity can be detected and evaluated—focusing particularly on plants—using proximal and remotely sensed hyperspectral data and other tools such as LiDAR. The volume, whose chapters bring together a large cross-section of the biodiversity community engaged in these methods, attempts to establish a common language across disciplines for understanding and implementing remote sensing of biodiversity across scales. The first part of the book offers a potential basis for remote detection of biodiversity. An overview of the nature of biodiversity is described, along with ways for determining traits of plant biodiversity through spectral analyses across spatial scales and linking spectral data to the tree of life. The second part details what can be detected spectrally and remotely. Specific instrumentation and technologies are described, as well as the technical challenges of detection and data synthesis, collection and processing. The third part discusses spatial resolution and integration across scales and ends with a vision for developing a global biodiversity monitoring system. Topics include spectral and functional variation across habitats and biomes, biodiversity variables for global scale assessment, and the prospects and pitfalls in remote sensing of biodiversity at the global scale.

"Creation of compensatory wetlands has been required in the U.S. since the late 1980s in an attempt to offset the massive decline in freshwater wetlands. To meet permitting requirements, vegetation composition in mitigation wetlands must be monitored for a minimum of five years following creation. Unfortunately, mitigated wetlands often lack the functionality of natural wetlands and may form hotspots for invasive plant species. However, wetland assessment is a time-consuming process that may also disturb fragile nascent plant communities. Thus there is a need for approaches that minimize disturbance, but still enable the collection of data over large portions of the landscape. Remote sensing, using hyperspectral imagery augmented by field data collection is a potential tool for rapid ecosystem assessment. In July 2010, vegetation community composition, spectral signatures of individual plant species, and plant canopies, and an aerial hyperspectral imagery dataset were obtained from two natural and two mitigation wetlands on the Rochester Institute of Technology (RIT) campus, Rochester, NY. We were able to locate specific wavelengths for four invasive plant species spectra that can be used to classify and map these species on the RIT campus with an overall accuracy of 94.34%. Reed canarygrass had a higher reflectance than the other three species and differences along the red-edge and near-infrared regions also enabled differentiation between broadleaf cattail and narrowleaf cattail. Values within the blue, red, red-edge, and near-infrared regions are needed to create a multi-spectral sensor with a larger emphasis on the red-edge and near-infrared regions. Such a sensor would be more readily available for land managers for classification and analysis of large plots of land, limiting the amount of time, personnel and funding needed to process the imagery and allowing managers to more rapidly identify patches of invasive plant species with minimal intrusion on sensitive wetland environments."--Abstract.

Invasion of non-native plant species, which has a significant impact on the earth’s ecosystems, has greatly increased in recent years due to expanding trade and transport among different countries. Understanding the ecological principles underlying the invasive process as well as the characteristics of the invasive plants is crucial for making good management decisions to address this problem. Invasive Plant Ecology includes chapters derived from presentations at conferences such as the World Congress of the International Union of Forestry Research Organizations (IUFRO), as well as contributions from invited renowned authors. The chapters include both original research and syntheses of current knowledge on specific topics. Actions essential for coordinated approaches to curtail plant invasion include increasing awareness of the ecological impacts of alien plants and employing novel control strategies. This book provides a foundation in invasion ecology by examining ecological theories and case studies that explain plant invasions, their impacts, management strategies, and the ecological economics. The chapters describe ecological characteristics, mutualistic associations, microbial communities, and disturbance regimes that affect the spread of invasive plants. The book also covers spatial analysis and predictive modeling of invasive plants. The final chapters offer guidelines for ecological management and restoration of invaded areas and describe the economics of the invasive plant issue. This collection contains case studies from around the world, giving readers a real view of the extent of the invasive species issue along with real-world strategies. With its focus on the ecological aspects of plant invasion, this book provides an important reference for students, scientists, professionals, and policy makers who are involved in the study and management of alien invasive plants and ecosystems.
