Greener cities, V.5. (News from the World of Trees).Intrigued by the idea of a program that translates tree cover into municipal cost savings?Check out AMERICAN American, river, 30 mi (48 km) long, rising in N central Calif. in the Sierra Nevada and flowing SW into the Sacramento River at Sacramento. The discovery of gold at Sutter's Mill (see Sutter, John Augustus) along the river in 1848 led to the California gold rush of FOREST'S latest version of its CITYgreen software. For the first time, CITYgreen 5.0 and the sample data needed to give it a try, are downloadable online at www.americanforests.org See .org. (networking) org - The top-level domain for organisations or individuals that don't fit any other top-level domain (national, com, edu, or gov). Though many have .org domains, it was never intended to be limited to non-profit organisations. RFC 1591. . Over the last 30 years, countless metropolitan areas have reported significant declines in canopy cover, a loss tied to rising urban populations. Nationwide, those losses add up to roughly 30 percent of the natural tree cover in our major urban areas. As cities continue to develop, the software offers a tool to help urban planners List of urban planners chronological by initial year of plan.
CITYgreen's latest version allows communities to investigate larger areas--watersheds, political boundaries within cities, or entire metropolitan areas. This version runs faster and more efficiently and allows users to access a wider variety of images, including high-resolution high-res·o·lu·tion adj. 1. Relating to an image that has fine detail. 2. a. Of or relating to an output device that produces images that contain a large number of dots per unit of area and are therefore sharp and classified satellite data. Once this data is classified into different land covers (trees, meadows, impervious surfaces Impervious surfaces are artificial structures, such as pavements and building roofs, which replace naturally pervious soil with impervious construction materials. They are an environmental concern because, with their construction, a chain of events is initiated that modifies urban , water, etc.), local communities can use it as a "green data layer" to better plan their urban areas. They can calculate the economic benefits of frees using CITYgreen software. Communities use these studies to show how metropolitan-area trees improve air quality and slow stormwater runoff Runoff The procedure of printing the end-of-day prices for every stock on an exchange onto ticker tape. Notes: If the "tape is late" then it can take a long time to print off all the closing prices. . Most cities can save millions of dollars annually with better free cover planning. A study of forest canopy in Salem, Oregon's 12 watersheds showed that by increasing tree cover from 17 to 25 percent, the city could save $17.5 million in stormwater storage costs.
