The roughly 125 million residents who live in the Northeast and Midwest benefit from forests every day (U.S. Census Bureau 2011). This region (figure 1) is fortunate to have 172 million acres of forests that provide clean air and water, wildlife habitat, and places for recreation (Smith and others 2009). These trees and forests help protect drinking water supplies for 52 million consumers (Barnes and others 2009). Forests-based businesses across the Northeast and Midwest employ 431,000 workers and yield nearly $125 billion in annual shipments of forest products (U.S.
Urban forests have many components: park trees, small woodlands, riparian buffers, street trees, and others. While some communities conduct citywide inventories of street tree populations, there has been no comprehensive, statewide sampling to characterize the structure, health, and function of street tree populations. A statewide Street Tree Monitoring pilot study was initiated by the USDA Forest Service, National Forest Health Monitoring Program to help fill data gaps in what is presently known (or unknown) about this segment of urban forests.
El propósito de la poda es tener plantas fuertes, sanas y atractivas. Esta meta se puede alcanzar sabiendo cómo, cuándo y por qué podar, y siguiendo unos cuantos principios muy sencillos. Las principales razones para podar árboles ornamentales y de sombra son: la seguridad, la salud y la estética. Además, la poda puede estimular la producción de fruta y elevar el valor de la madera.
Urban areas across the nation have tripled in extent since the 1950s.5 Chances are that you are among the 80 percent of Americans who live in the urban and community forest. There are many ways to invest in community forests and support sustainable local programs that protect, manage, maintain, and plant trees. Your State forestry agency and the U.S. Forest Service work together with cities and towns, nonprofit organizations, tree care professionals, neighborhood groups, and volunteers, to create greener, more livable communities.
The Inventory Pest Evaluation and Detection (IPED) protocol provides a portable, accessible, and standardized method of observing a tree for possible insect or disease problems. It is intended to be a standardized protocol for long-term urban pest detection and monitoring throughout the United States. This field guide will help you identify the signs and symptoms of tree stress, insect pests, and diseases, which will enable you to make informed, systematic decisions when collecting data using the IPED protocol.
