Tb196: Temperature, Soil Moisture, And Streamflow At The Bear Brook Watershed In Maine (Bbwm), Ivan J. Fernandez, Joseph E. Karem, Stephen A. Norton, Lindsey E. Rustad

Technical Bulletins

The Bear Brook Watershed in Maine is a whole-ecosystem chemical manipulation initiated in 1987 to study the effects of acid deposition on forests and surface waters. The focus of this research was to understand the biogeochemical response of watersheds with emphasis on chemistry and hydrology. In 2001 a program was initiated to provide more detailed measurements of temperature and moisture to examine critical linkages amongst chemical, biological, and physical processes that ultimately work together to define ecosystem function. The purpose of this publication is to provide data from the initial phase of soil temperature, air temperature, and soil moisture measurements …


Sharing A Landscape: The Construction Of Sense Of Place On The Maine Coast, Andrea Jane Ednie Dec 2007

Sharing A Landscape: The Construction Of Sense Of Place On The Maine Coast, Andrea Jane Ednie

Electronic Theses and Dissertations

Motivated by interest and concern over the changing coastline in Maine, this study uses the concept of sense of place to develop an understanding of how a range of users share the resource, and to explore how place meanings are associated with their social experiences and perceptions. The site for this study was the Stonington region archipelago, an area that has not yet experienced the same amount of development as seen on the southern Maine coast, yet one that has witnessed a boom in recreational use and an influx of people from other areas. Using a mixed methodology, two groups …


Biomass And Biofuels In Maine: Estimating Supplies For Expanding The Forest Products Industry, Jonathan Rubin, Kate Dickerson, Jacob Kavkewitz Nov 2007

Biomass And Biofuels In Maine: Estimating Supplies For Expanding The Forest Products Industry, Jonathan Rubin, Kate Dickerson, Jacob Kavkewitz

Energy & the Environment

This paper estimates the renewable energy potential of Maine’s forest resources, and how much energy these resources could potentially provide the state. Using the most recent state-specific data available, and a methodology similar to the Billion Tons Report, we find that ethanol production from Maine’s forest residues could potentially provide 18% of Maine’s transportation (gasoline) fuels with a fermentation wood to ethanol process. Making Fischer-Tropsch diesel (F-T diesel) using forest residues can replace 39% of Maine’s petro-diesel consumption. Actual levels of biofuels that can be produced will depend on conversion factors and forestry residue removals that are subject to uncertainty.

Myriophyllum Heterophyllum Michx. (Haloragaceae): Control And Vegetative Reproduction In Southwestern Maine, Jacolyn E. Bailey May 2007

Myriophyllum Heterophyllum Michx. (Haloragaceae): Control And Vegetative Reproduction In Southwestern Maine, Jacolyn E. Bailey

Electronic Theses and Dissertations

Native to the southeastern United States, variable-leaf watermilfoil (Myriophyllum heterophyllum) is an invasive species in the Northeast and has been documented in Maine lakes for twenty years. Variable-leaf watermilfoil is targeted by the Maine Department of Environmental Protection as a species of grave concern as it has aggressively colonized twenty-six water bodies in Maine. This aquatic invasive plant grows in dense mats and outcompetes native vegetation. It is causing both ecological and economic disruption to Maine's lakes and ponds. The plants clog boat motors and deter people from swimming and other water related activities. Allofragmentation and autofragmentation occur …


Research Note: The Hazardous Search For Ancestors, Gordon W. Stuart Jan 2007

Research Note: The Hazardous Search For Ancestors, Gordon W. Stuart

Maine History

The following is an account of the search for an old family cemetery and the events that impacted the farm on which it was located over a 250 year period. Gordon Stuart, who recorded these events as a way of illustrating the perils and triumphs of genealogical research, is a retired hydrologist with national experience in water quality issues on forest and agriculture land. He volunteers with a lake association, a river watch group, and participates in woodlot education programs in Southern Maine.


Early Life Stage Characteristics Of Six Acadian Conifer Species: Germination And Seedling Development In A Changing Climate, Jason D. Schatz Jan 2007

Early Life Stage Characteristics Of Six Acadian Conifer Species: Germination And Seedling Development In A Changing Climate, Jason D. Schatz

Electronic Theses and Dissertations

Global climate change will drastically alter regional climates. The influence of these changes on the distribution and relative abundance of forest trees is both critically important and subject to substantial uncertainty. It will be particularly important to understand the effects of different climate scenarios on the early life stages of major tree species, because: 1) Early life stage performance and survival strongly influence the abundance of mature trees of a given species, 2) Trees are most sensitive to environmental variation during their early life stages, and 3) Our knowledge of the response of Acadian Forest tree species to environmental variation …


The Maine Woods: A Legacy Of Controversy, Richard W. Judd Jan 2007

The Maine Woods: A Legacy Of Controversy, Richard W. Judd

Maine Policy Review

In the Margaret Chase Smith Essay, Richard Judd reflects on the history of Maine’s North Woods. He discusses the divergent interests with a stake on the North Woods over the centuries, but notes that there has been a long-standing interest in conservation and in the heritage represented by this vast region.


Forging A Common Vision For Maine’S North Woods, Robert J. Lilieholm Jan 2007

Forging A Common Vision For Maine’S North Woods, Robert J. Lilieholm

Maine Policy Review

Robert Lilieholm takes stock of the challenges and opportunities facing Maine’s North Woods, the largest undeveloped forested block in the eastern United States. In the face of changing ownership patterns and development pressures, there is lively debate over current land use policies and trends. Lilieholm suggests that a broader, regional vision for the North Woods might better serve the long-term interests of both the area’s forests and its struggling communities.


The Importance Of Maine For Ecoregional Conservation Planning, Robert F. Baldwin, Stephen C. Trombulak, Karen Beazley, Conrad Reining, Gillian Woolmer, John R. Nordgren, Mark Anderson Jan 2007

The Importance Of Maine For Ecoregional Conservation Planning, Robert F. Baldwin, Stephen C. Trombulak, Karen Beazley, Conrad Reining, Gillian Woolmer, John R. Nordgren, Mark Anderson

Maine Policy Review

Ecoregional conservation planning aims at protecting biodiversity within a realistic social and economic framework. The authors of this article suggest that Maine’s forests are the ecological core of the entire Northern Appalachian/Acadian ecoregion, which spans four states and five Canadian provinces. Using mapping and mathematical models of the “human footprint,” they note that Maine has a large, contiguous, undeveloped and unfragmented forest compared with neighboring states and provinces. However, compared with its neighbors Maine also has the largest proportion of unprotected forest. The authors conclude with the hope that land use policy and planning can be better informed through the …


Methods For The Translocation Of The Yellow Lampmussel (Lampsilis Cariosa) And The Tidewater Mucket (Leptodea Ochracea) In The Fort Halifax Dam Impoundment Of The Sebasticok River, Maine, Jennifer Elaine Kurth Jan 2007

Methods For The Translocation Of The Yellow Lampmussel (Lampsilis Cariosa) And The Tidewater Mucket (Leptodea Ochracea) In The Fort Halifax Dam Impoundment Of The Sebasticok River, Maine, Jennifer Elaine Kurth

Electronic Theses and Dissertations

Translocation from areas where habitat alterations are proposed can be an important mussel conservation tool. Pending removal of the Fort Halifax dam on the Sebasticook River in Maine potentially would result in extensive mortality of two statelisted threatened species of mussels, yellow lampmussels (Lampsilis cariosa) and tidewater muckets (Leptodea ochracea), which occur in the impoundment above the dam. My study assessed populations of these two species in the impoundment, and determined the effects of within- and between-waterbody translocations on survival. I conducted a qualitative survey of the Fort Halifax dam impoundment in 2004 to determine locations …

Seeing The Forest For The Trees: The Future Of Timber Investing In The North Woods -- A Conversation With Clark S. Binkley, Peter Howell

Maine Policy Review

In this conversation with Peter Howell, Clark Binkley draws on his long-term experience as a timberland investment manager to give his analysis of and forecast for timber markets and timber investing in the Northern Forest. While he is not optimistic about the current prospects for such investments, he does believe that there are some opportunities in conservation easements, residential development, and possibly biofuels and carbon credits.


From Diamond International To Plum Creek: The Era Of Large Landscape Conservation In The Northern Forest, Sara A. Clark, Peter Howell Jan 2007

From Diamond International To Plum Creek: The Era Of Large Landscape Conservation In The Northern Forest, Sara A. Clark, Peter Howell

Maine Policy Review

The last two decades have seen dramatic, unprecedented growth in conservation lands in the Northern Forest, stretching from upstate New York through Maine. The conservation community, in coordination with public agencies, has been able to take advantage of changing forest ownership structure and a significant expansion of public and private funding to support this increase in protected lands. As Sara Clark and Peter Howell discuss, Maine has been a laboratory for some of the largest and most innovative land transactions. Maine is unique in having land conservation strategies focused almost entirely on permanent protection of privately owned land rather than …

Are The Economics Of A Sustainable Maine Forest Sustainable?, Mike Levert, Charles S. Colgan, Charles Lawton Jan 2007

Are The Economics Of A Sustainable Maine Forest Sustainable?, Mike Levert, Charles S. Colgan, Charles Lawton

Maine Policy Review

Mike LeVert, Charles Colgan and Charles Lawton discuss the transformation of the economic environment of Maine’s forests over the past two decades. Paper companies have sold most of their holdings; residential and conservation demand for land has increased; forestland prices have skyrocketed; and new classes of landowners have different strategies, objectives, and time horizons than the old industrial landowners. The authors believe that management of Maine’s forests must now address changes in the economic environment with the same intensity as threats such as the spruce budworm were addressed if we are to keep Maine’s forests as forests.
