Prudence Island Narragansett Bay Research Reserve
Last Updated 1/20/07 Prudence Island Narragansett Bay Research Reserve Background Prudence Island is located in the geographic center of Narragansett Bay. The island is approximately 7 miles long and 1 mile across at its widest point. Located at the south end of the island is the Narragansett Bay Research Reserve’s Lab & Learning Center. The Center contains educational exhibits, a public meeting area, library, and research labs for staff and visiting scientists. The Reserve manages approximately 60% of Prudence; the largest components are at the north and south ends of Prudence Island. The vegetation on Prudence reflects the extensive farming that took place in the area until the early 1900s. After the fields were abandoned, woody plants gradually replaced the herbaceous species. The uplands are now covered with a dense shrub growth of bayberry, blueberry, arrowwood, and shadbush interspersed with red cedar, red maple, black cherry, pitch pine and oak. Green briar and Asiatic bittersweet cover much of the island as well. Prudence Island also supports one of the most dense white-tailed deer herds in New England . Raccoons, squirrels, Eastern red fox, Eastern cottontail rabbits, mink, and white-footed mice are plentiful. The large, salt marshes at the north end of Prudence are used as feeding areas by a number of large wading birds such as great and little blue herons, snowy and great egrets, black-crowned night herons, green-backed herons and glossy ibis. Between September and May, Prudence Island is also used as a haul-out site for harbor seals. History of Prudence Island Before colonial times, Prudence and the surrounding islands were under the control of the Narragansett Native Americans. -
Patience Island Narragansett Bay Research Reserve
Last Updated 1/20/07 Patience Island Narragansett Bay Research Reserve Background This 207-acre island lies to the west of northern Prudence Island. At their closest, the two islands are only 900 feet apart. The Patience Island is dominated by tall shrubs interspersed with red cedar and black cherry. Common shrubs include bayberry, highbush blueberry, and shadbush. Much of the island is also covered by brier, Asiatic bittersweet and poison ivy. A deciduous forest is gradually replacing the shrub habitat in some parts of the island. The small salt marsh on the southeastern shore provides habitat for seablite, a plant species common in other areas of the country, but rare in Rhode Island. The upland area of Patience Island supports a variety of wildlife including white-tailed deer, red fox, and Eastern cottontail rabbits. Coastal areas are used extensively by migrant and wintering waterfowl species such as horned grebes, greater scaup, black ducks and scoters. Quahogs are abundant in the sandy sediment. There is no ferry service available to this island. Visitors are welcome but you must provide your own transportation. Be aware that there is a high population of ticks, the trails may be overgrown, and camping is not permitted. History of Patience Island Historically, the Patience Island Farm covered an area of approximately 200 acres, nearly the entire island, and was a working farm as early as the mid-seventeenth century. The farm buildings were burned by the British during the Revolutionary War. After the war, the buildings were rebuilt and the farm remained in operation until the early twentieth century. -

Broad Beach Restoration Project Coastal Development Permit
Broad Beach Restoration Project Coastal Development Permit Project Description FINAL PREPARED FOR: TRANCAS PROPERTY OWNER’S ASSOCIATION PREPARED BY: 3780 KILROY AIRPORT WAY, SUITE 600, LONG BEACH, CA 90806 JANUARY 2011 JOB NO. 6935 1. INTRODUCTION 2 Broad Beach is located in the northwest portion of the County of Los Angeles and within the City of Malibu. The project area is comprised of the shoreline area fronting approximately 80 homes spanning approximately from Lechuza Point to Trancas Creek. Broad beach has been suffering shoreline erosion over the past 30 plus years, resulting in an almost complete loss of recreation and public access. Public access through dedicated public access ways from Broad Beach Rd. to the beach was rendered impossible during the most severe storms and tidal action over the past few years. The severe erosion problem now threatens private property and dune fields along this stretch of beach. The Trancas Property Owner’s Association (TPOA), representing almost all of the property owners along the Broad Beach shoreline, has elected to address the extensive erosion by privately funding a beach and sand dune restoration project which will not only protect their homes but also restore the beach to its historic grandeur not only for their benefit but for the benefit of the public at large. The Broad Beach restoration project seeks to design, permit, and implement a shoreline restoration program that provides erosion control, property protection, improved recreation and public access opportunities, aesthetics, and dune habitat. Broad Beach Restoration – Project Description FINAL The vicinity and location of the project site are shown below in figure 1. -

The Yunlin coast, a first-level protection area in mid-west Taiwan, was then used as an example to illustrate the proposed design criteria. The safety of the present coastal defenses and land use of the Yunlin coastal area was assessed, and coastal protection measures for hazard prevention were proposed based on the generated risk map. The results can be informative for future coastal management and the promotion of sustainable development of coastal zones. Keywords: coastal defense; risk maps; non-engineering measure; coastal vulnerability 1. Introduction Like most developing countries, Taiwan’s coast has been alternatively used for settlement, agriculture, trade, industry, and recreation without careful and thorough planning in the development stage since 70s.
