Download or read book Los Angeles 1 Million Tree Canopy Cover Assessment written by E. Gregory McPherson and published by DIANE Publishing. This book was released on 2010-11 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Million Trees LA initiative intends to chart a course for sustainable growth through planting and stewardship of trees. This study measures LA's existing tree canopy cover (TCC), determines if space exists for 1 million additional trees, and estimates future benefits from the planting. Benefits were forecast for planting of 1 million trees between 2006 and 2010, and their growth and mortality were projected until 2040. LA's existing TCC was 21%. There is potential to add 2.5 million additional trees to the existing population of 10.8 million, but only 1.3 million of the potential tree sites are deemed realistic to plant. Thus, there is space for planting 1 million new trees. Benefits for the 1-million-tree planting were between $1.33 band $1.95 billion.

Book excerpt: The Million Trees LA initiative intends to chart a course for sustainable growth through planting and stewardship of trees. The purpose of this study was to measure Los Angeles's existing tree canopy cover (TCC), determine if space exists for 1 million additional trees, and estimate future benefits from the planting. Highresolution QuickBird remote sensing data, aerial photographs, and geographic information systems were used to classify land cover types, measure TCC, and identify potential tree planting sites. Benefits were forecast for planting of 1 million trees between 2006 and 2010, and their growth and mortality were projected until 2040. Two scenarios reflected low (17 percent) and high (56 percent) mortality rates. Numerical models were used with geographic data and tree size information for coastal and inland climate zones to calculate annual benefits and their monetary value. Los Angeles's existing TCC was 21 percent, and ranged from 7 to 37 percent by council district. There is potential to add 2.5 million additional trees to the existing population of approximately 10.8 million, but only 1.3 million of the potential tree sites are deemed realistic to plant. Thus, there is space for planting 1 million new trees. Benefits for the 1-million-tree planting for the 35-year period were $1.33 billion and $1.95 billion for the high- and low-mortality scenarios, respectively. Average annual benefits were $38 and $56 per tree planted. Eighty-one percent of total benefits were aesthetic/other, 8 percent were stormwater runoff reduction, 6 percent energy savings, 4 percent air quality improvement, and less than 1 percent atmospheric carbon reduction. Recommendations included developing a decisionsupport tool for tree selection and tracking, as well as establishing a model parking lot greening program.

Download or read book Urban Tree Canopy Assessment written by and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An urban Tree Canopy (UTC) assessment, which provides a measure of a community's tree canopy cover, is important for understanding the extent of a community's forest or tree resource. UTC assessments are often used for establishing and implementing municipal tree canopy goals as part of broader urban greening and sustainability initiatives. Most useful when it is combined with other information-such as the extent of impervious surfaces, socioeconomic and health data, traffic density, and heat island maps-UTC assessment contributes to broader urban greening goals, enabling communities to craft management plans and make policy decisions to optimize benefits from urban forests. This report provides an overview of the approaches, methods, and data sources used in UTC assessments, focusing on the initial steps of project planning, assessment, and analysis. The report also provides general guidelines for conducting UTC assessments and analysis to ensure useful, quality results that can be applied in management and decision-making efforts, and resources for planning and implementing the UTC assessment process. The report is designed to help personnel involved in urban natural resource planning move forward with UTC project planning and assessment.

Download or read book Assessment of Tree Condition written by John L. Innes and published by . This book was released on 1990 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest condition is now assessed annually in most European countries. This field book provides details of assessment procedures used by the Forestry Commission in their main monitoring programme. Although this programme is restricted to Sitka spruce, Norway spruce, Scots pine, oak and beech, the techniques that are described are applicable with little or no modification to most other tree species. While emphasis has been placed on the assessment of crown density, a variety of other indexes are also used. These are described and an assessment system is provided for each parameter. The additional indices enable a full description to be made of the condition of a tree.
Download or read book Assessing Urban Forest Effects and Values written by and published by . This book was released on 2006 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of trees in Washington, D.C. reveals that this city has about 1,928,000 trees with canopies that cover 28.6 percent of the area. The most common tree species are American beech, red maple, and boxelder. The urban forest currently store about 526,000 tons of carbon valued at $9.7 million. In addition, these trees remove about 16,200 tons of carbon per year ($299,000 per year) and about 540 tons of air pollution per year ($2.5 million per year). The structural, or compensatory, value is estimated at $3.6 billion. Information on the structure and functions of the urban forest can be used to improve and augment support for urban forest management programs and to integrate urban forests within plans to improve environmental quality in the Washington, D.C. area.
Download or read book Accuracy Assessment of Percent Canopy Cover Cover Type and Size Class written by Hans T. Schreuder and published by . This book was released on 2003 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Truth for vegetation cover percent and type is obtained from very large-scale photography (VLSP), stand structure as measured by size classes, and vegetation types from a combination of VLSP and ground sampling. We recommend using the Kappa statistic with bootstrap confidence intervals for overall accuracy, and similarly bootstrap confidence intervals for percent correct for each category and user and producer accuracy. A procedure is given for mapped plots to be assessed as being partially or totally correct. We recommend the use of primary accuracy for management decisions and secondary accuracy for research decisions to distinguish between accuracy desired.

Download or read book Sustaining America s Urban Trees and Forests written by David John Nowak and published by . This book was released on 2010 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Close to 80 percent of the U.S. population lives in urban areas and depends on the essential ecological, economic, and social benefits provided by urban trees and forests. However, the distribution of urban tree cover and the benefits of urban forests vary across the United States, as do the challenges of sustaining this important resource. As urban areas expand across the country, the importance of the benefits that urban forests provide, as well as the challenges to their conservation and maintenance, will increase. The purpose of this report is to provide an overview of the current status and benefits of America's urban forests, compare differences in urban forest canopy cover among regions, and discuss challenges facing urban forests and their implications for urban forest management.

Download or read book Trees Outside Forests written by R. Bellefontaine and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2002 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trees outside forests (including fruit trees, trees in parks, fields, those growing in the wild and as amenities), together with forests and other woodlands, contribute to the structure of the landscape, generate numerous environmental and social services, and yield important food, drink and fuel products as well as meeting other domestic needs of urban and rural populations. However, trees outside forests are not well documented and receive little attention in the formulation of national forestry policy and planning. This publication seeks to fill this gap, by providing information on the role of these resources and options for their integration in territorial management policies.
