Cupriferous swamps are characterized by high concentrations of copper in the soil and water. The Aboushagan swamp, situated 8km northwest of Sackville, New Brunswick is a unique metalliferous wetland where copper is naturally sequestered in the peat without having a significant negative effect on the vegetation. This paleoecological history of this region is not well known and few studies have attempted to characterize the local vegetation trends. This study investigates the post-glacial vegetation history of the swamp as well as any relationship it may have with the copper present in the peat. Surface peats (dry weight) have previously been found to contain up to 10% copper. This study found Cu content in two peat cores ranged from trace values to a high of 4800 µg/g and 25 000 µg/g (0.48 and 2.5 % dry weight copper). Despite the increased values, there was no detectable change in pollen due to copper concentration and any increase of copper in the peat material is likely a result of post depositional hydrological processes transporting copper into the layers of peat where it is being sequestered in the organic material and never becoming bioavailable to the surface vegetation. Pollen revealed that following deglaciation, the Aboushagan swamp began to develop as a rich fen around 10.7 ka BP that transitioned into a poor fen with Sphagnum around 9.9 ka BP as the wetland basin filled in. Around 8290 ka BP, temperatures warmed and the soil dried up leading to more canopy cover and fern abundance which yielded a mixed coniferous-deciduous swamp with Sphagnum in the understory that persisted until approximately 1.4 ka BP. Maritime vegetation trends in other studies describe a pine maxima (7.5 ka BP) and hemlock maxima (6.5-4.5 ka BP), neither of which were not found in the pollen record here due to a lack of peat accumulation between 8290 and 4350 ka BP. This is likely due to a regional climatic change that increased temperatures and decreased summer precipitation between 8 and 4 ka BP. In the last 1.5ka BP, the swamp has been dominated by spruce but other trees such as pine, fir, and birch have grown in abundance in the last few hundred years. A decrease in overall pollen abundance and concentration near the top of the core may be evidence for the little ice age event (1450 cal years BP). Today the swamp is a typical mixed coniferous-deciduous swamp with Picea mariana, Larix laricina, Acer rubrum, and Abies balsamea. An understanding of the swamp’s ability to sequester copper from becoming bioavailable has implications for the rehabilitation of contaminated industrial landscapes with wetland technologies. This study also highlights the high sensitivity with which wetlands can be used to detect and differentiate between autogenic (local) and allogenic (regional) climatic and vegetation changes while describing the vegetation community succession in the Aboushagan basin since the last deglaciation.

The Preservation movement was born out of the realization that a significant portion of our natural and cultural resources are rapidly being consumed, lost, or destroyed in the process of contemporary development. When the preservation movement began, preservationists split into two distinctly separate philosophical groups, Natural Resource Preservationists and Cultural Resource Preservationists. Natural Resource Preservationists focused upon an ecological understanding of the universe, and fought to maintain an ecological balance, while Cultural Resource Preservationists concentrated on saving each archeological or architectural artifact. The result of this divided approach produced monuments to the grand and fantastic, and museums to the famous and nationalistic, but failed to recognize the significance of the `ordinary landscape'. Ordinary landscapes are identified by the material components created by various cultures, and these components are physical representations of the human response to the natural environment that speaks will, beliefs, and the manipulation of the natural world that surrounds them.Recognizing the dynamic and continuously evolving layers of the Cultural Landscape is a critical aspect in Cultural Landscape identification and requires that the symbiotic relationship between the human occupants and the natural environment be understood within the social, political, and natural context. The basis of this project is to establish the social, political and natural context of the Black Swamp region in northwest Ohio in order to reveal the process of landscape transformation in the 'Black Swamp', and to identify areas of the landscape that may contain significant Cultural Landscapes.The 'Black Swamp' lies parallel to the east bank of the Maumee River from Lake Erie southwest to New Haven, Indiana and measures approximately 1500 square miles. Formation of the Black Swamp and the Maumee River Valley began approximately 25,000 years ago, when the Wisconsin glacier advanced southeast out of Canada and into Ohio. Glacial movement compressed the topography into its flattened form while meltwater eroded a channel known as the Maumee River.The basin-like shape of the Maumee River Valley transported water slowly to the Maumee River. Organic matter accumulated in the drainage basin and composted into a rich black loamy soil 12"-15" thick that rested on an impervious clay subsoil. Rich in humus, the transported water of the Maumee River ran black, providing nourishment for a wide variety of vegetation, which in turn supported diverse forms of wildlife.Three distinct cultures occupied the region between the years 1700 and 1850. Native Americans, Euro-American pioneers, and American settler farmer, utilized, manipulated, and transformed the `Black Swamp' environment in varying degrees, however it was the Euro-American pioneer and the American settler farmer that exerted drastic changes upon the swamp forest environment that ultimately transformed native forest into a cultivated and highly mechanized corn belt landscape.Little, if any, components remain of the Native American culture that occupied the region for over 10,000 years. However, this study has found that the settlement and transportation patterns of the Native Americans were in each case overlapped by the subsequent culture. These initial patterns of settlement and transportation layed out by the Native American were in response to the character of the natural environment and this response created the organization of the Black Swamp landscape upon future cultures layered various components. / Department of Architecture
