This book was released on 2018 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Since 2010 approximately 129 million trees in California have been killed by bark beetle attacks. The detection and mapping of bark beetle infestations is an important component for monitoring overall forest health and sustainability. Using remote sensing techniques and European Space Agency (ESA) Sentinel-1 and Sentinel-2 imagery, bark beetle infestation in the southern Sierra Nevada range were mapped. Sentinel-1 Synthetic Aperture Radar imagery was co-registered with Sentinel-2 multispectral imagery and the machine learning algorithms Random Forest and Support Vector Machines were utilized in a supervised classification scheme on two user generated training and validation data samples. The observed accuracy for this analysis ranged from 79.1% to 88.7%. As climate change intensifies, it can be expected that the extent and severity of epidemic bark beetle mortality will continue to spread in western North America. The investigation of bark beetle outbreaks and subsequent impacts is an important component to monitoring overall forest health and sustainability.

This book was released on 2021-06-02 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The great potential of remote sensing technologies for operational use in sustainable forest management is addressed in this book, which is the reprint of papers published in the Remote Sensing Special Issue “Operationalization of Remote Sensing Solutions for Sustainable Forest Management”. The studies come from three continents and cover multiple remote sensing systems (including terrestrial mobile laser scanning, unmanned aerial vehicles, airborne laser scanning, and satellite data acquisition) and a diversity of data processing algorithms, with a focus on machine learning approaches. The focus of the studies ranges from identification and characterization of individual trees to deriving national- or even continental-level forest attributes and maps. There are studies carefully describing exercises on the case study level, and there are also studies introducing new methodologies for transdisciplinary remote sensing applications. Even though most of the authors look forward to continuing their research, nearly all studies introduced are ready for operational use or have already been implemented in practical forestry.

Download or read book Long Term Ecological Research written by Felix Müller and published by Springer Science & Business Media. This book was released on 2010-06-21 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecosystems change on a multitude of spatial and temporal scales. While analyses of ecosystem dynamics in short timespans have received much attention, the impacts of changes in the long term have, to a great extent, been neglected, provoking a lack of information and methodological know-how in this area. This book fills this gap by focusing on studies dealing with the investigation of complex, long-term ecological processes with regard to global change, the development of early warning systems, and the acquisition of a scientific basis for strategic conservation management and the sustainable use of ecosystems. Within this book, theoretical ecological questions of long-term processes, as well as an international dimension of long-term monitoring, observations and research are brought together. The outcome is an overview on different aspects of long-term ecological research. Aquatic, as well as terrestrial ecosystems are represented.
Download or read book Linking Survey Detection Accuracy with Ability to Mitigate Populations of Mountain Pine Beetle written by S. Coggins and published by . This book was released on 2009 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the period 1999 to 2006, the mountain pine beetle impacted an estimated 10.1 million hectares of pine forest in British Columbia, Canada. Surveys to detect the location, size, and impact of infestations are conducted from field, airborne, and satellite perspectives. Importantly, the differing survey approaches characterize the infestation over dissimilar spatial scales (i.e., trees, stands, landscapes), and with varying levels of detection accuracy. In this report, the authors provide background for understanding differing survey approaches, the nature of the information generated, the resultant detection accuracies that may be expected, and the link between survey accuracy and the ability to mitigate a given mountain pine beetle infestation.--Document.

Download or read book Working Paper Monitoring Tree level Insect Population Dynamics with Multi scale and Multi source Remote Sensing written by Michael A. Wulder and published by . This book was released on 2008 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long-term monitoring of the rate of change of mountain pine beetle (Dendroctonus ponderosae Hopkins) populations requires detailed tree-level information over large areas. This information is used to assess the status of an infestation (e.g., increasing, stable, or decreasing), and to select and evaluate mitigation approaches. In this research project, the authors develop and demonstrate a prototype monitoring system, which enables the extrapolation of tree-level estimates of beetle damage from field data to a larger study area using a double sampling approach, and multi-scale, multi-source, high spatial resolution remotely sensed data. The project study area encompasses over 6 million ha and is located at the leading edge of an ongoing mountain pine beetle epidemic along the provincial border between British Columbia and Alberta, within the Dawson Creek Timber Supply Area (TSA) of British Columbia and the Northwest Boreal Forest Management Unit in Alberta.--Document.

This book was released on 2017 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The San Bernardino National Forest (SBNF) has experienced periods of high, concentrated bark beetle epidemics in the late 1990’s and into the 2000’s. This increased activity has caused huge amounts of forest loss, resulting from disease introduced by bark beetles. Using remote sensing techniques and Landsat Thematic Mapper 5 (TM5) imagery, the spread of bark beetle diseased trees is mapped over a period from 1998 to 2008. Acreage of two attack stages (red and gray) were calculated from a level sliced classification method developed on data training sites. In each image using Normalized Difference Vegetation Index (NDVI) is the driver of forest health classifications. The results of the analysis are classification maps for each year, red acreage estimated for each study year, and gray attack acreage estimated for each study year. Additionally, for the period of 2001–2004, acreage was compared to those reported by the USDA with a thirteen percent lower mortality total in comparison to USDA federal land and a thirty-two percent lower total mortality (federal and non-federal) land in the SBNF.
