This book was released on 1971 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid, inexpensive methods of monitoring land use change can greatly facilitate the planning of urban fringe development by use of synoptic remotely sensed imagery and urban growth theory. The urbanization of Walnut Valley, California from 1953-71 prompted land use change from intensive von Thunen market-oriented patterns to extensive, disinvested, production-factor-minimized patterns. Aerial photography used synoptically recorded six periods of land use change that bracketed dates before and after the freeway was announced and built. Interpretations of these changes help to deal with rural-urban transition problems before they arise.

This book was released on 2016 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space-borne remote sensing is a rapidly evolving field and is exceptionally useful for monitoring landscape dynamics. The increasing impact of humans on natural ecosystems via land use change and climate change make ecological monitoring vital to environmental health. Human population levels are causing rapid changes in land cover and development, which in turn puts increasing stress on the natural landscape. Anthropogenic greenhouse gas emissions have accelerated climate change causing varied unexpected changes to vegetation. The effects of increased frequency and intensity of drought in the western United States is an example of this which can be monitored using satellite imagery. This dissertation assesses how these human-induced threats are driving landscape changes and the application of remote sensing to assess the ecological impacts. To address these objectives, remote sensing is applied to natural resource monitoring for effective conservation-based land management (Chapter 2). These methods are then applied to various research, including monitoring ecological status of southern California National Parks (Chapter 3), assessment of the effects of drought on southern California native plants (Chapter 4) and on browning over California vegetation zones (Chapter 5). The remote sensing-based analyses utilize several best practice methods such as supervised classification and time series statistics to examine landscape changes throughout California. Outputs include a standardized protocol to determine future ecological conservation management actions, status reports on current and historical land use, publically available spatial datasets, and assessment of the California landscape and native species in response to 20th Century drought conditions.

This book was released on 2015 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rehabilitating river corridors to restore valuable riparian habitat consumes significant resources from both governments and private companies. Given these considerable expenditures, it is important to monitor the progress of such projects. This study evaluated the utility of using Landsat Thematic Mapper remotely-sensed data from 2002 and 2009 to monitor vegetation change induced by instream flow restoration to the Lower Owens River in central California. This study compared the results of an unsupervised classification with an NDVI threshold classification to appraise the resources required and effectiveness of each analysis method. The results were inspected by creating standard remote sensing accuracy error matrices and by correlating landscape pattern metrics with bird indicator species. Both sets of classified maps show a noticeable increase in riparian vegetation in the study area following flow restoration in 2006, indicating an improvement of the quality of bird habitat. The study concluded that analyzing vegetation change using the unsupervised classification technique required more effort, expert knowledge, and supplementary data than using the NDVI threshold method. If these prerequisites are met, the output from the unsupervised classification process produces a more precise map of land cover change than the NDVI threshold method. However, if an analyst is lacking either resources or ground verification data, the NDVI threshold technique is capable of providing a generalized, but still valid evaluation of vegetation change. This conclusion is supported by higher correlations between indicator bird species under the unsupervised classification method than were found with the NDVI threshold method.

This book was released on 2016 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protected area (PA), usually built to address the potential ecological pressure from different sources, aims to sustain, protect, and maintain the wilderness of nature for ecological, economic, and scenic purposes. Establishing, maintaining, and expanding the monitor network of PAs helps to enhance the ecological and biological value of these areas, especially in the light of species decline and habitat degradation. Intensively monitored and regulated through various administrative agencies, California keeps one of the best maintained network of PAs in the world, which supports various studies to address the significant threats to the preservation of wilderness from the projected warming climate and pressure from human development, including water deficit and prolonged drought, abnormality in wildfires, urban sprawl, and light pollution. With the help of satellite remote sensing technologies and geospatial analysis, we can overcome the limitation of data availability in traditional ecological studies and expand the study of PAs to a continuous gradient both in time and space. This dissertation aims to develop a comprehensive understanding through remote sensing technologies on three signi cant and linked ecological disturbance in California PAs, including the change of land cover, the dynamic of wildfire, and the extent and intensity of human activity reflected by stable nighttime light. Exploiting various of remote sensing observation and its derivatives, this study investigated the three topics through trend, seasonality, abnormality, spatial distribution, and hotspot of change to provide a cost-effective and repeatable studying paradigm for PA managers to better understand the past and present situation, as well as the ecological challenges of PAs. In addition, it also supplemented the study of PAs as a case study focusing on a non-tropic ecosystem, which usually involves greater interaction with human thus faces ecological pressure at a higher level. The analysis on land cover dynamics and change from 2000 to 2015 found that many protected areas in California have experienced an increase of brownness since 2000. PAs with a higher coverage of greenness are associated with a higher temporal variability, mostly because of the more complex life cycle of green vegetation and the sensitivity to the disturbance, possibly due to a drying climate regime. Partly linked to the gradual influence from the drying climate, the change in the regime of wildfire may cause a more drastic change in land cover, through the removal of aboveground biomass and its in uence on the post-wild re regrowth. In the study focusing on California PAs from 2000 to 2013, a shift in wildfire-prone land cover and season was observed starting from 2008, while the wildfires southern California shrubland during the fall season became nearly extinct and the northern California evergreen forest wildfires in the late spring increased, partly explained by the recent loss of available fuel in biomass and the increase of potential of ignition in evergreen forest as a result of prolonged drought. Most burned areas experienced a signi cant weakening of the immediate growing season, although the in uence from re on local landscape decayed over time, which became irrelevant after ve years on average. The lower fuel moisture and a more intensive removal of aboveground biomass makes shrubs more sensitive in time, with a shorter period for biomass removal by re and a greater delay in the start and peak of post- re growing season. The long-enduring and sometimes intensive disturbance from human activity, especially from the development can be even more disastrous than wild re in damaging the aboveground biomass by interrupting the natural nutrient and mass circulation,thus brings more fundamental and sometimes irreversible consequences to ecosystems. However, after decades of protection, especially the removal of settlements in side PAs, land management strategies may have bored beneficial fruits to reduce the negative effects from historical human disturbance. As a good proxy of human activity and development, the historical records of stable nighttime light from 1992 to 2012 tracked the temporal change and spatial migration of hotspot of human activity inside California PAs. A decrease of lit area at night inside PAs occurred from 1992 to 2012, with a turning point around 2004 when the relatively sharp decrease started from became more gradual thereafter. Besides, area covered by higher stable nighttime light not only shrank, but also retreated from the area with high wilderness. If solidly con rmed by other socioeconomic variable, the above nding demonstrated the e ectiveness of PA establishment and the fruits of multiple conservation strategies kept for decades. The investigation of three major disturbances to the wilderness of California PAs provided an example of exploiting the cost-e ective and continuously available observation of the Earth surface at a regional level to understand the ecological challenges of PAs. The findings can help the National Park Service and other related agencies of PA administration in the review, adjustment, and proposal of regulations and policies regarding to PAs. Future work and analysis can be focused on improving the accuracy of predictive models involved the analysis, either by concentrating on the di erence between categories of protection, or through a better understanding on the related ecological process and mechanisms to identify or develop better explanatory variables. In addition, when conducting analysis on PAs, the bu er area adjacent to PAs cannot be ignored, which is an important source of disturbance to PAs as well as an ecological corridor that links nearby PAs into clusters. Considering the great diversity in the landscape of PAs, the analytical results can be aggregated and interpreted by different ecoregions to derive more accessible guidance to local policy makers.
