North Carolina's Dis cove r North Carolin a’s River Basins ENVIRONMENTAL North Carolina is a diverse land with natural beauty that appeals to residents EDUCATION and visitors alike. It is also a land experiencing competition for its natural resources that are already under stress and that could be lost to us in the absence of a wide spread awareness of their existence, their significance and their value. Natural resources are not isolated from each other or the people who use them. Each resource is an integral part of the ecosystem. When one part of the system is affected, other parts feel the impact. It is environmental education that provides the knowledge, understanding and awareness of this intercon nected ness of all things and gives us the ability to make informed environmental decisions. The more we understand and respect our own community, the more capable we are of being good stewards of the environment. If you have ever visited one of North Carolina’s many Environmental Education Centers —nature centers, parks, aquariums, museums, the zoo, public gardens, etc. —then you have already started appreciating natural systems and had fun while learning about them. Environmental education is not issue advocacy or a biased point of view. Environmental education enables communities to care for their own environ - ment. Living within the limits set by the environment depends on the beliefs and commitment of individuals. Individuals working together as a community have more power to promote practices that can nourish rather than cripple their natural life-support systems. I N TH E 1990 S , several crises elevated rivers in the public consciousness. First came Pfiesteria , a lethal organism that killed millions of fish in coastal waters. Then a series of hurricanes brought river and development issues to the fore - front . How we treat rivers and the land around them has a direct relation ship to our quality of life. The purpose of this booklet is to describe how river basins func tion and how humans and rivers are interconnected. It demon strates how decisions we make as home owners and citizens affect the quality of the water we drink, swim in and fish from. With this knowl edge, individ uals can make more informed deci - North Carolina’s sions regarding their environment.

The land - water found in scape is made up of many inter connected cracks and pores in sand, gravel watersheds. Within each watershed, all water and rocks below runs to the lowest point—a stream, river, lake the earth’s surface or ocean. On its way, water travels over the land surface —across farm fields, forestland, suburban lawns and city streets, or it seeps into the soil and travels as groundwater .

As water moves downstream, it carries and redeposits gravel, sand and silt. Water also transfers bacteria, chemicals, excess nutrients and organic matter. Whatever happens to the surface water or groundwater upstream will even tu ally affect downstream systems. Therefore, the health of the aquatic ecosystem is directly related to activities on land. 1 North Carolina’s Phoenix Mtn.

  • Lesson 4: Sediment Deposition and River Structures
    LESSON 4: SEDIMENT DEPOSITION AND RIVER STRUCTURES ESSENTIAL QUESTION: What combination of factors both natural and manmade is necessary for healthy river restoration and how does this enhance the sustainability of natural and human communities? GUIDING QUESTION: As rivers age and slow they deposit sediment and form sediment structures, how are sediments and sediment structures important to the river ecosystem? OVERVIEW: The focus of this lesson is the deposition and erosional effects of slow-moving water in low gradient areas. These “mature rivers” with decreasing gradient result in the settling and deposition of sediments and the formation sediment structures. The river’s fast-flowing zone, the thalweg, causes erosion of the river banks forming cliffs called cut-banks. On slower inside turns, sediment is deposited as point-bars. Where the gradient is particularly level, the river will branch into many separate channels that weave in and out, leaving gravel bar islands. Where two meanders meet, the river will straighten, leaving oxbow lakes in the former meander bends. TIME: One class period MATERIALS: . Lesson 4- Sediment Deposition and River Structures.pptx .

  • Community Analysis of Pitcher Plant Bogs of the Little River Canyon National Preserve, Alabama
    COMMUNITY ANALYSIS OF PITCHER PLANT BOGS OF THE LITTLE RIVER CANYON NATIONAL PRESERVE, ALABAMA Robert Carter, Terry Boyer, Heather McCoy, and Andrew J. Londo1 Abstract—Pitcher plant bogs of the Little River Canyon National Preserve in northern Alabama contain the federally endan- gered green pitcher plant [Sarracenia oreophila (Kearney) Wherry]. Multivariate analysis of the bog vegetation and envi- ronmental variables revealed three communities with unique species compositions and soil characteristics. The significant soil characteristics were percent A-horizon sand and A-horizon depth. A blackgum (Nyssa sylvatica Marsh.)-yellow poplar (Liriodendron tulipifera L.)-azalea [Rhododendron canescens (Michx.) Sweet] type was found on sites bisected by ephemeral streams with a closed canopy. A scarlet oak (Quercus coccinea Muenchh.) -flowering dogwood (Cornus florida L.) -sweet goldenrod [Solidago speciosa Nutt. var. erecta (Pursh) MacM.] type was found on upland sites close to the canyon rim and along perennial streams sites. A smooth yellow false foxglove [Aureolaria flava (L.) Farw.]-pale-spike lobelia (Lobelia spicata Lam.)- violet lespedeza [Lespedeza violacea (L.) Pers.] type was found on relatively flat sites away from the canyon rim.

  • Braided River Management: from Assessment of River Behaviour to Improved Sustainable Development
    BR_C12.qxd 08/06/2006 16:29 Page 257 Braided river management: from assessment of river behaviour to improved sustainable development HERVÉ PIÉGAY*, GORDON GRANT†, FUTOSHI NAKAMURA‡ and NOEL TRUSTRUM§ *UMR 5600—CNRS, 18 rue Chevreul, 69362 Lyon, cedex 07, France (Email: [email protected]) †USDA Forest Service, Corvallis, USA ‡University of Hokkaido, Japan §Institute of Geological and Natural Sciences, Lower Hatt, New Zealand ABSTRACT Braided rivers change their geometry so rapidly, thereby modifying their boundaries and flood- plains, that key management questions are difficult to resolve. This paper discusses aspects of braided channel evolution, considers management issues and problems posed by this evolution, and develops these ideas using several contrasting case studies drawn from around the world. In some cases, management is designed to reduce braiding activity because of economic considerations, a desire to reduce hazards, and an absence of ecological constraints. In other parts of the world, the eco- logical benefits of braided rivers are prompting scientists and managers to develop strategies to preserve and, in some cases, to restore them. Management strategies that have been proposed for controlling braided rivers include protecting the developed floodplain by engineered structures, mining gravel from braided channels, regulat- ing sediment from contributing tributaries, and afforesting the catchment. Conversely, braiding and its attendant benefits can be promoted by removing channel vegetation, increasing coarse sediment supply, promoting bank erosion, mitigating ecological disruption, and improving planning and devel- opment. These different examples show that there is no unique solution to managing braided rivers, but that management depends on the stage of geomorphological evolution of the river, ecological dynamics and concerns, and human needs and safety.

The civilizations create laws, centralized governments, writing systems, and advanced technologies. The process of trade spreads new ideas to and from these civilizations. Agriculture Changes Society • Agriculture dramatically changed Stone Age societies by providing a larger and more reliable food supply. • Some people began to live as nomadic pastoralists. • Others gave up the nomadic lifestyle and formed settlements, pooling their resources. Early Farming Societies New Technologies • Small settlements • New tools and methods • Villages and towns • Animals working in fields • Increase in trade • Grindstones, pestles, pottery • Societies became more complex • Wool from sheep for yarn • Social status, male authority • Spinning and weaving • Religion, megaliths • Copper, bronze, tin • Warfare, disease increased • As people began to make items from bronze, the Stone Age gave way to the Bronze Age, which began as early as 3000 BCE in some areas.
