“An Urban Forestry Program Really Has No End… It Will Require The A REGIONAL URBAN FOREST INITIATIVE An urban forestry program really has no end… It will require “ the continued commitment of citizens, local tree groups and the elected officials of this generation and those of the future.” USDA FOREST SERVICE SACRAMENTO TREE FOUNDATION June 2005 BACKGROUND The State of the Trees Report, published by the Sacramento Tree Foundation in 2000, laid out a bold vision: to capitalize on the remarkable benefits of trees to create the best urban forest for the Sacramento region. As a result, in 2001 elected officials Beginning in 2005, residents and representing twenty municipalities in stakeholders were invited to participate in our six-county region took an exciting leap a public involvement campaign to contribute towards regional collaboration by signing their thoughts and ideas in reviewing the an Urban Forest Compact. The Compact first draft of the Greenprint. Over 35 proposed a shared vision and identified presentations were made to elected bodies, goals to optimize the benefits of our region’s civic groups, professional organizations, urban forest. service clubs and general community meetings. Hundreds of citizen participants Over the next three years, an educational from Colfax to Winters, Live Oak to Galt, campaign produced a video and brochure, and all compass points between helped both titled What’s the Value of a Tree. In craft the best approaches to greening our specific detail they describe the benefits of communities. trees and their financial value to our region. Other educational materials described the The Greenprint represents the thinking and significant economic and health benefits that vision of the Tree Foundation board and trees provide, and detailed the supporting staff, members of the scientific community, studies conducted by leading scientists. urban foresters and arborists, civic and elected leaders and concerned citizens from throughout the region. 2 2 Sacramento Regional GREENPRINT GUIDING PRINCIPLES FOR CITIES AND COUNTIES Our region is remarkably well suited to capture the benefi ts of trees.

URBAN HEAT ISLAND IMAGE CANOPY MAKES A HEALTHY COMMUNITY The Greenprint invites our region’s cities and counties to develop livable and sustainable communities by building the best urban forests. Scientifi c investigations by a variety of nationally recognized research institutions have quantifi ed a long list of tree-related benefi ts including improved air quality, energy conservation, attraction and retention of business, extended roadway life, water quality and stormwater mitigation, erosion prevention, dust removal, skin cancer prevention, summer air temperature relief and more. In 1998, the National Aeronautics and Space Administration (NASA) AIR took fl yover thermal image shots of Sacramento to analyze the urban heat 10 million pounds of air pollutants island effect. The urban heat island effect is caused by condensed areas of hard surfaces that radiate heat $25 million in annual air pollution clean-up from the sun, which results in higher temperatures. For example, the red areas in the image above are 118˚ Fahrenheit, WATER while green areas are 82˚ Fahrenheit. One of the most effective ways to 1.75 billion gallons of rainwater mitigate urban heat islands is to increase shade with tree canopy. $17.5 million in annual stormwater runoff costs 4 energ Y SH ade C over A dds Value to O ur R egion Building an urban forest agenda begins by recognizing the pivotal role 30% annual savings on summer cooling costs of canopy cover in the development of our communities.

  • Urban Reforestation Site Assessment
    Urban Watershed Forestry Manual Chapter 2. Urban Reforestation Site Assessment The Urban Reforestation Site Assessment (URSA) is used to collect detailed information about planting site conditions. The URSA provides a tool to help organize important data to help determine where and what to plant, and what special methods are needed to prepare the site and reduce conflicts due to existing site constraints. The purpose of an URSA is to collect data at the most promising reforestation sites in an urban watershed, in order to develop detailed planting plans. The goal is to have all the available information about an individual planting area contained in a single form. This chapter describes the URSA in detail. For more information on methods to select, screen, and prioritize candidate planting sites across a watershed or development site, consult Part 1 (Chapter 2) and Part 2 (Chapter 2) of this manual series. Nine major elements are evaluated at each potential reforestation site to develop an effective planting strategy: 1. General Site Information – information about the location, property owner, and current land use at the site. 2. Climate – climate data, to help select tree and shrub species 3. Topography – local topographic features that may present planting difficulty 4. Vegetation – data on current vegetative cover, to determine if removal of vegetation is necessary and to select tree and shrub species 5. Soils – soil characteristics, to determine if soil amendments are needed, and to select appropriate tree and shrub species 6. Hydrology – site drainage, to determine if the site has capacity to provide water quality treatment of storm water runoff, and to select tree and shrub species most tolerant of the prevailing soil moisture regime 7.

    Testimony of Dr. Joseph Fargione Science Director, North America Region, The Nature Conservancy Before the US House of Representatives Select Committee on the Climate Crisis October 22, 2019 Chair Castor, Ranking Member Graves, and members of the Committee, thank you for inviting me to testify on natural solutions to cutting pollution and building resilience. I am Joseph Fargione, Science Director for the North America Region of The Nature Conservancy (TNC). Founded in 1951, TNC is a global environmental nonprofit working to create a world where people and nature can thrive. Thanks to more than a million members and the dedicated efforts of our diverse staff and more than 400 scientists, we work in all 50 U.S. states and impact conservation in 72 countries across six continents. Climate change is no longer a distant threat. We are currently living with its impacts, as Americans are seeing chronic drought, rising seas, record high temperatures, more frequent extreme storms and fires, and significant economic losses (USGCRP 2017). The climate crisis is endangering people, livelihoods, and decades of work on the conservation of America’s wildlife and environment. Addressing climate change is necessary to create a world where both people and nature thrive, where we provide food and goods for our growing population, design healthy and livable cities, and conserve and protect lands, freshwaters, and oceans. To create this world, American innovation and leadership is both capable and necessary. The Nature Conservancy is committed to tackling climate change and to helping vulnerable people and places deal with the impacts of a changing climate, including increasingly extreme weather conditions.

  • Urban Forestry and the Eco-City: Today and Tomorrow
    fI 32 oct .y Urbo q "f0r t'."l r ! >I. !>c c ::; y6+ C'Y" ).-~~d '-' 27 Urban Forestry and the Eco-City: Today and Tomorrow Margaret M. Carreiro and Wayne C. Zipperer In 1990, the Chicago Academy of Sciences held a conference, Sustainable Cities: Preserving and Restoring Urban Biodiversity, which led to the publication of a book entitled The Ecological City (Platt et aI., 1994). This symposium differed from others on cities at that time by focusing principally on cities as habitats for biodiversity. The thrust of the symposium was that interactions between people and nonhuman biological entities in urban landscapes had not received much scientific attention and warranted increased ecological investigation. More than a decade later in Shanghai, the International Meeting on Urban Forestry and Eco-Cities conference explored the role of urban forestry in creating more environmentally sound cities that enhance people's quality of life. During the interval between these two symposia, urban ecology has rapidly developed as an ecological discipline exploring the myriad elements that comprise an urban landscape. No longer are urban ecologists trying to convince the ecological community that urban land­ scapes are important and productive subjects for research, trying to convince planners that ecological concepts need to be incorporated into urban design, or try­ ing to convince environmental managers that a multiple scale approach is needed to manage ecological goods and services and to restore habitats. However, this symposium also revealed that implementation of these principles can be 'difficult for a variety of reasons, not the least of. which is that we still do not understand the nuances of the political and socioecological interactions that affect the structure and function of urban landscapes and how they can be influenced to improve environ­ mental conditions citywide (e.g., Perkins et aI., 2004).
