The Garigliano alluvial-coastal plain, at the Latium-Campania border (Italy), witnessed a long-lasting history of human-environment interactions, as demonstrated by the rich archaeological knowledge. With the aim of reconstructing the evolution of the landscape and its interaction with human activity during the last millennia, new pollen results from the coastal sector of the Garigliano Plain were compared with the available pollen data from other nearby sites. The use of pollen data from both the coastal and marine environment allowed integrating the local vegetation dynamics within a wider regional context spanning the last 8000 years. The new pollen data presented in this study derive from the analysis of a core, drilled in the coastal sector, which intercepted the lagoon-marshy environments that occurred in the plain as a response to the Holocene transgression and subsequent coastal progradation. Three radiocarbon ages indicate that the chronology of the analyzed core interval ranges from c. 7200 to c. 2000 cal yr BP. The whole data indicate that a dense forest cover characterized the landscape all along the Prehistoric period, when a few signs of human activity are recorded in the spectra, such as cereal crops, pasture activity and fires. The main environmental changes, forced by natural processes (coastal progradation) but probably enhanced by reclamation works, started from the Graeco-Roman period and led to the reduction of swampy areas that favoured the colonisation of the outer plain.

Oxon Run Parkway (OXRN) is a 51-hectare (126-acre) natural area within Washington, D.C. administered by the National Park Service under National Capital Parks East (NACE). The original plan called for a road, slated to follow Oxon Run stream, but this never came to fruition; despite this, the moniker stuck. The majority of the original Oxon Run Parkway is managed by the District of Columbia. The section of Oxon Run Parkway under NPS jurisdiction contains wetlands and forests, as well as the only McAteean magnolia bogs still remaining in the District. The lower Cretaceous Potomac Group, known as one of the few dinosaur-bearing rock units on the east coast of North America, crops out within Oxon Run. One of the most prevalent fossil-bearing resources are the siderite, or “bog iron” sandstone slabs that sometimes preserve the footprints or trackways of various vertebrates, including dinosaurs. Such trackways have been reported from Potomac Group outcrops throughout the Atlantic Coastal Plain of Maryland and Virginia. In 2019, National Capital Parks-East took possession of such a track, referred to a dinosaur, collected by paleontologist Dr. Peter Kranz. This report was compiled after a paleontological survey of Oxon Run Parkway and is intended as a supplement to the National Capital Parks East Paleontological Resource Inventory (Nelson et al. 2019). This report contains information on the history of Oxon Run Parkway and its geology, as well as discussion of the fossil track.

Bermudagrass (Cynodon spp.) is the foundation of the turfgrass industry in most tropical and warm-temperate regions. Development of bermudagrass as a turfgrass began in the early 1900s. Many of the cultivars commercially available today have been cooperatively released by the U.S. Department of Agriculture Agricultural Research Service (USDA-ARS) and the University of Georgia at the Coastal Plain Experiment Station in Tifton, GA.

During the 1980s and 1990s there were two major changes to forest management objectives in Tanzania. Firstly, it was recognized that some of the forests, notably those on mountains in the east of the country and the coastal plain, are exceptionally rich in species of restricted distribution. Recent analysis has even placed these forests amongst the most important biodiversity hotspots world-wide. Secondly, there was a recognition that communities needed to be much more involved in forest management. The Forest Act, 2002, which replaces the 1957 Forest Ordinance, tackles both of these objectives and introduces some new concepts of forest ownership. Moreover it makes arrangements for establishing a fund that promotes protection of biodiversity and sustainable development of forest resources. This note first briefly reviews the history of forest law in Tanzania and then discusses innovations introduced by the 2002 Act.

The history of Oman is largely a story of competition, and often conflict, between two very different entities. This duality was even symbolized by the name of the country, “Sultanate of Muscat and Oman,” until 1970. The sultanate was formed from the fusion of the Batina coastal plain and its port cities, symbolically Muscat, and the interior of the country, Oman. During most periods in the recent history of the country, only the coast has been ruled by the sultan. Even before the institution of the sultanate emerged in the 18th century, however, the coast had usually been under separate, often foreign, rule. In the interior, the ideal head of government from very early times was that of an imam, even though the office often remained vacant. At many times during Omani history, of course, one part of the country or the other imposed its control and Oman was temporarily united, but the differences between the two sections of Omani society eventually split the country into two separate states again. Even within the last decade, one of the major problems in Oman's efforts to develop has been “the traditional antithesis between the sultan residing on the coast and the inwardly oriented tribes.”
