While shrimp farming has been economically successful, it has received criticism for being environmentally harmful, most notably because of farms replacing mangrove forests. Legislation regulating aquaculture development and technological responses to disease outbreak have had a large influence on the land use of the Thai coast. The objective of this research is to provide a systematic examination of how regulation and technology development have influenced land use in this region. To accomplish this, Landsat derived data were analyzed at the national and provincial scale to determine how Thai coastal land use systems change over time. I found that interrelated changes in technology and legislation have had complex influences on the landscape, which encourage both the restriction and expansion of aquaculture growth depending on time and location.

A validated hydrodynamic model of Jamaica Bay, New York City (NYC), is used to test nature-based adaptation measures in ameliorating flooding for NYC’s two largest historical coastal flood events. In addition to control runs with modern bathymetry, three altered landscape scenarios are tested: (1) increasing the area of wetlands to their 1879 footprint and bathymetry, but leaving deep shipping channels unaltered; (2) shallowing all areas deeper than 2 m in the bay to be 2 m below Mean Low Water; (3) shallowing only the narrowest part of the inlet to the bay. These three scenarios are deliberately extreme and designed to evaluate the leverage each approach exerts on water levels. They result in peak water level reductions of 0.3%, 15%, and 6.8% for Hurricane Sandy, and 2.4%, 46% and 30% for the Category-3 hurricane of 1821, respectively (bay-wide averages). These results suggest that shallowing can provide greater flood protection than wetland restoration, and it is particularly effective at reducing "fast-pulse" storm surges that rise and fall quickly over several hours, like that of the 1821 storm. Nonetheless, the goal of flood mitigation must be weighed against economic, navigation, and ecological needs, and practical concerns such as the availability of sediment.

  Citation × Citation Citation Abstract Copy Title: Dead wood dynamics and relationships to biophysical factors, forest history, ownership, and management practices in the Coastal Province of Oregon, USA Author: Kennedy, Rebecca S.H. Dead wood patterns and dynamics vary with biophysical factors, disturbance history, ownership, and management practices. Through field and modeling studies, I examined the current and potential future amounts of dead wood in two landscapes and region-wide in the Coastal Province of Oregon. The objectives of the first study were to (1) determine whether two landscapes with different recent disturbance histories differ in the amount and characteristics of dead wood; and (2) explore relationships between patterns of dead wood in each landscape to potentially related factors including topography. The objectives of the second study were to (1) describe current regional amounts of dead wood; (2) compare dead wood amounts across ownerships; (3) determine relationships between current dead wood amounts and ownership, current and past vegetation conditions, climate, topography, and soils; and (4) evaluate whether the factors related to dead wood patterns differed according to the scale of analysis. The objectives of the third study were to (1) characterize the projected future change in dead wood amounts in a multi-ownership Province; (2) determine the longevity of present-day dead wood of different types and sizes in relation to amendments from management and stand development; and (3) evaluate differences in management approaches in transitional dynamics and long-term patterns of dead wood. In the first study, I sampled logs and snags at four topographic positions (streams, lower slopes, middle slopes, upper slopes) in the Tillamook State Forest and the Siuslaw National Forest. These two landscapes experienced catastrophic fire at different points in recent history. I developed statistical models relating various attributes of dead wood abundance to biophysical variables related to climate, topography, historical vegetation, current vegetation, soils, and ecoregion. I found that the type and timing of disturbance was important to dead wood amounts and characteristics, and that potential source and sink areas for dead wood were related to topographic position. In particular, lower slopes had higher amounts of logs, and upper slopes had higher basal areas of potential source wood, in the form of snags and legacy (pre-fire) stumps. Climatic factors were of greater relative importance to overall gradients of dead wood in the landscape in which fire occurred less recently. In the second study, I analyzed dead wood data from a region-wide systematic grid of field plots according to ownership and biophysical variables at multiple scales of resolution including plots, subwatersheds. Dead wood abundance and types varied greatly among ownerships, with public lands (Forest Service, Bureau of Land Management, State of Oregon) typically having higher amounts of dead wood and more dead wood in the larger size classes than the private lands (forest industry, non-industrial private). I found that the relative influence of ownership, topography, current and historical vegetation, and climate varied with scale of resolution. Current vegetation was of greater relative importance at finer scales of plots and subwatersheds, whereas climate, topography, and historical vegetation were of greater relative importance at coarser scales of watersheds and subbasins. Ownership was important to overall dead wood gradients at all scales considered. In the third study, by simulating stand development and dead wood dynamics under various forest management scenarios over a 300-year period, I was able to examine the long-term effects of management on dead wood abundance in the Coastal Province. I estimated potential upper bounds for future dead wood amounts. Dead wood amounts increased over time on average across the Province, mainly because of policies on public lands, especially the federal lands under the Northwest Forest Plan. Forest industry, under the Oregon Forest Practices Act and assuming retention of all snags at harvest and thinning, maintained amounts of dead wood that were similar to present-day levels, but size classes shifted toward the smaller sizes as existing large legacy dead wood decomposed. Non-industrial private lands showed increases from very low present-day amounts of dead wood. Across the Province, legacy logs and snags remained present for over a century of the simulation period, and buffered effects of intensive management to dead wood amounts. Variation across landscapes in starting conditions meant that contrasting management approaches had differential effects on long-term dead wood dynamics depending on where they were applied. Current amounts of dead wood and live vegetation patterns in the Province resulted from historical fire and logging. Results of this simulation study indicate that recently established policies oriented toward dead wood production and retention, in the absence of fire or other large- or mid-scale disturbances, are likely to result in increases in dead wood amounts that greatly exceed present-day levels. My results suggest that dead wood patterns of abundance will continue to diverge according to land ownership and that management practices that foster dead wood creation are of increasing importance to the long-term abundance of large dead wood as legacy dead wood is lost through decomposition.

  Citation × Citation Citation Abstract Copy Title: “Up On the Mountain”: Ethnobotanical Importance of Montane Sites In Pacific Coastal North America Author: Turner, Nancy J., Deur, Douglas, Mellott, Carla Rae Year: 2011 The Pacific Coastal Mountains of western North America have immense ethnobotanical significance. Since time immemorial, Indigenous Peoples have journeyed from permanent settlements in lowland regions to upland sites in order to harvest and process a range of plant resources –foods, materials and medicines– as well as to hunt and fish, and undertake spiritual activities. Two culturally significant montane areas, widely separated geographically, are described as case examples: pt-e´n’i (Botanie Valley) in Nlaka’pmx territory of southern interior British Columbia, famous for its abundance of edible root resources; and iwamkani, an iconic huckleberry picking location for the Klamath in southern Oregon. Patterns of montane use are notably consistent throughout the region. Indigenous People intentionally modified montane landscapes through fire and other means to enhance resource productivity and predictability. In turn, mountain environments and resources have significantly influenced Indigenous Peoples’ lifeways and knowledge systems. The integrity of montane biocultural systems has been threatened by industrial development, fire suppression and, most recently, the changing global climate. Yet, montane areas remain as key elements of biocultural heritage and must be protected for continued social-ecological health and well-being of Indigenous Peoples.

  Citation × Citation Citation Abstract Copy Title: Ecological thresholds, climate extremes, and tree species' distributions across the Pacific coastal United States Author: Lintz, Heather E. Species' distributions across the landscape are perhaps the least understood yet most conspicuous features of life on earth. Ecologists have long studied species' distributions; yet, many questions remain about why species occur where they do. Such questions persist largely because species' distributions are complex systems with challenging properties like non-linearity, high dimensionality, and strong interactions. One impediment to our understanding of species' distributions is the use of standard quantitative approaches, which have limitations when applied to data from complex systems. The objective of this work is to develop tools that can be used to improve our understanding of natural complexity, in particular, factors relating to species’ distributions at large scales. Our study systems are tree species’ distributions from Forest Inventory Analysis (FIA) sites across the Pacific coastal USA. This work advances the detection and measurement of thresholds in response surfaces (e.g. representing tree species’ niches), the evaluation of the consequences of a major change in sampling and measurement methodology associated with the FIA program, and the relationship of climatic extremes and means to tree species’ distributions.

  Citation × Citation Citation Abstract Copy Title: Geoarchaeological Investigations at the Devils Kitchen Site (35CS9), Southern Oregon Coast Author: Curteman, Jessica Ann A geoarchaeological investigation was conducted at the Devils Kitchen archaeological site, located in the Devils Kitchen State Park along the southern Oregon coast. In this thesis research, the author paired previous and recent excavated stratigraphy profiles to define culturally significant deposits. These stratigraphic units were defined further geochemically using a multivariate statistical analysis from data gathered by a portable x-ray fluorescence. Radiocarbon dates from excavated charcoal samples associated with cultural artifacts show an intact deposit dating from 10,638±35 to 11,596±37 RCYBP. The author used textural analysis from Ro-Tap sieve shaker data and Munsell color identification extracted from 33 bucket auger units to subsurface test the Devils Kitchen State Park area. The auger samples portray an uplifted aeolian landscape once influenced by alluvial deposition, commonly observed along coastal environments altered by rising sea levels. This research applied a geoarchaeological method to identify deposits of the right age (DORA) that have the potential to contain intact, early evidence of prehistoric people. The identification of DORA can serve as a marker for future coastal research searching for rare, intact paleolandscapes and archaeological deposits dating to the late Pleistocene to mid Holocene.
