    Comparison of Swamp Forest and Phragmites Australis

    COMPARISON OF SWAMP FOREST AND PHRAGMITES AUSTRALIS COMMUNITIES AT MENTOR MARSH, MENTOR, OHIO A Thesis Presented in Partial Fulfillment of the Requirements for The Degree Master of Science in the Graduate School of the Ohio State University By Jenica Poznik, B. S. ***** The Ohio State University 2003 Master's Examination Committee: Approved by Dr. Craig Davis, Advisor Dr. Peter Curtis Dr. Jeffery Reutter School of Natural Resources ABSTRACT Two intermixed plant communities within a single wetland were studied. The plant community of Mentor Marsh changed over a period of years beginning in the late 1950’s from an ash-elm-maple swamp forest to a wetland dominated by Phragmites australis (Cav.) Trin. ex Steudel. Causes cited for the dieback of the forest include salt intrusion from a salt fill near the marsh, influence of nutrient runoff from the upland community, and initially higher water levels in the marsh. The area studied contains a mixture of swamp forest and P. australis-dominated communities. Canopy cover was examined as a factor limiting the dominance of P. australis within the marsh. It was found that canopy openness below 7% posed a limitation to the dominance of P. australis where a continuous tree canopy was present. P. australis was also shown to reduce diversity at sites were it dominated, and canopy openness did not fully explain this reduction in diversity. Canopy cover, disturbance history, and other environmental factors play a role in the community composition and diversity. Possible factors to consider in restoring the marsh are discussed. KEYWORDS: Phragmites australis, invasive species, canopy cover, Mentor Marsh ACKNOWLEDGEMENTS A project like this is only possible in a community, and more people have contributed to me than I can remember.
  • Transitions for the Delta Economy

    Transitions for the Delta Economy

    Transitions for the Delta Economy January 2012 Josué Medellín-Azuara, Ellen Hanak, Richard Howitt, and Jay Lund with research support from Molly Ferrell, Katherine Kramer, Michelle Lent, Davin Reed, and Elizabeth Stryjewski Supported with funding from the Watershed Sciences Center, University of California, Davis Summary The Sacramento-San Joaquin Delta consists of some 737,000 acres of low-lying lands and channels at the confluence of the Sacramento and San Joaquin Rivers (Figure S1). This region lies at the very heart of California’s water policy debates, transporting vast flows of water from northern and eastern California to farming and population centers in the western and southern parts of the state. This critical water supply system is threatened by the likelihood that a large earthquake or other natural disaster could inflict catastrophic damage on its fragile levees, sending salt water toward the pumps at its southern edge. In another area of concern, water exports are currently under restriction while regulators and the courts seek to improve conditions for imperiled native fish. Leading policy proposals to address these issues include improvements in land and water management to benefit native species, and the development of a “dual conveyance” system for water exports, in which a new seismically resistant canal or tunnel would convey a portion of water supplies under or around the Delta instead of through the Delta’s channels. This focus on the Delta has caused considerable concern within the Delta itself, where residents and local governments have worried that changes in water supply and environmental management could harm the region’s economy and residents.

Using a combination of moderate-high spatial resolution ( 30 meters) optical and synthetic aperture radar (SAR) satellite imagery, we evaluated several ≤ approaches for mapping and characterization of wetlands of the Chesapeake and Delaware Bays. Sentinel-1A, Phased Array type L-band Synthetic Aperture Radar (PALSAR), PALSAR-2, Sentinel-2A, and Landsat 8 imagery were used to map wetlands, with an emphasis on mapping tidal marshes, inundation extents, and functional vegetation classes (persistent vs. non-persistent). We performed initial characterizations at three target wetlands study sites with distinct geomorphologies, hydrologic characteristics, and vegetation communities.

    NATIONAL WETLANDS INVENTORY and the NATIONAL WETLANDS RESEARCH CENTER PROJECT REPORT FOR: GALVESTON BAY INTRODUCTION the U.S. Fi

    NATIONAL WETLANDS INVENTORY AND THE NATIONAL WETLANDS RESEARCH CENTER PROJECT REPORT FOR: GALVESTON BAY INTRODUCTION The U.S. Fish & Wildlife Service's National Wetlands Inventory is producing maps showing the location and classification of wetlands and deepwater habitats of the United States. The Classification of Wetlands and Deepwater Habitats of the United States by Cowardin et al. is the classification system used to define and classify wetlands. Upland classification will utilize the system put forth in., A Land Use and Land Cover Classification System For Use With Remote Sensor Data. by James R. Anderson, Ernest E. Hardy, John T. Roach, and Richard E. Witmer. Photo interpretation conventions, hydric soils-lists and wetland plants lists are also available to enhance the use and application of the classification system. The purpose of the report to users is threefold: (1) to provide localized information regarding the production of NWI maps, including field reconnaissance with a discussion of imagery and interpretation; (2) to provide a descriptive crosswalk from wetland codes on the map to common names and representative plant species; and (3) to explain local geography, climate, and wetland communities. II. FIELD RECONNAISSANCE Field reconnaissance of the work area is an integral part for the accurate interpretation of aerial photography. Photographic signatures are compared to the wetland's appearance in the field by observing vegetation, soil and topography. Thus information is weighted for seasonality and conditions existing at the time of photography and at ground truthing. Project Area The project area is located in the southeastern portion of Texas along the coast. Ground truthing covered specific quadrangles of each 1:100,000 including Houston NE, Houston SE, Houston NW, and Houston SW (See Appendix A, Locator Map).

    To: Donita Cotter, Monarch Conservation Strategy Coordinator From: Dr. Benjamin N. Tuggle, Regional Director, Southwest Region (R2) Subject: Region 2 Monarch Butterfly Conservation Strategy and Action Plan Template Date: November 12, 2014 On 4 September 2014, the U.S. Fish and Wildlife Service (USFWS) Director issued a memorandum to the Service Directorate to develop a Service strategy for monarch conservation addressing plans for habitat restoration and enhancement, education and outreach, and monitoring and research needs. On October 7, the Director sent an email to all Regional Directors challenging them to commit to a goal of 100 Million Monarchs by 2020, and for Region 2 to provide a goal of 20,000 acres of new habitat for monarchs. The Director’s requests followed an agreement among President Obama, President Peña Nieto of Mexico, and Prime Minister Harper of Canada to “establish a working group to ensure the conservation of the Monarch butterfly, a species that symbolizes our association.” Also, on June 20, 2014, President Obama signed a Presidential Memorandum, “Creating a Federal Strategy to Promote the Health of Honey Bees and Other Pollinators,” outlining an expedited agenda to address the devastating declines in honey bees and native pollinators, including the monarch butterfly. Secretary Jewell tasked the Director with convening an interagency High Level Working Group to develop and implement a U.S. strategy for monarch conservation, coordinate our efforts with Mexico and Canada through the Trilateral Committee, and ensure that the monarch strategy is coordinated with development of the Federal Pollinator Strategy and DOI assignments in the Presidential Memo. To accomplish these initiatives and provide information to update the 2008 North American Monarch Conservation Plan by March 2015 and completion of the Federal Pollinator Strategy due to the White House mid-December 2014, the following tasks were specifically requested in the Director’s memorandum: I.
  • Funding the East Contra Costa Fire Protection District

    Funding the East Contra Costa Fire Protection District

    Contact: Jim Mellander Foreperson 925-608-2621 Contra Costa County Grand Jury Report 17XX Funding the East Contra Costa Fire Protection District TO: Contra Costa County Board of Supervisors, East Contra Costa Fire Protection District, Brentwood City Council, Oakley City Council SUMMARY The East Contra Costa Fire Protection District (ECCFPD) was formed in 2002 and serves the communities of Brentwood, Oakley, Knightsen, Byron, Discovery Bay, Bethel Island, and the Marsh Creek area. In 2009, ECCFPD closed five of its eight fire stations because it lacked the funds to operate them. ECCFPD receives the lowest allocation of ad valorem property taxes of any fire district in Contra Costa County, 7% of the 1% ad valorem property tax levied on properties. ECCFPD and the cities of Brentwood and Oakley have placed initiatives on the ballot to fund the reopening of closed stations. However, property owners have rejected parcel tax assessments, and the residents of Brentwood and Oakley similarly have rejected utility taxes. Three fire stations are insufficient to provide adequate urban and suburban fire protection coverage in a fire district with a population of 110,000 and an area of 249 square miles. Response times have increased since the closure of stations. ECCFPD should continue its efforts to reopen fire stations by seeking the necessary funding to do so through tax ballot measures and reallocation opportunities. Additionally, the City of Brentwood, the City of Oakley, and the County should collect impact fees for ECCFPD capital improvements,

Center for Ecosystem Management and Restoration CONTRA COSTA COUNTY Marsh Creek Watershed Marsh Creek flows approximately 30 miles from the eastern slopes of Mt. Diablo to Suisun Bay in the northern San Francisco Estuary. Its watershed consists of about 100 square miles. The headwaters of Marsh Creek consist of numerous small, intermittent and perennial tributaries within the Black Hills. The creek drains to the northwest before abruptly turning east near Marsh Creek Springs. From Marsh Creek Springs, Marsh Creek flows in an easterly direction entering Marsh Creek Reservoir, constructed in the 1960s. The creek is largely channelized in the lower watershed, and includes a drop structure near the city of Brentwood that appears to be a complete passage barrier. Marsh Creek enters the Big Break area of the Sacramento-San Joaquin River Delta northeast of the city of Oakley. Marsh Creek No salmonids were observed by DFG during an April 1942 visual survey of Marsh Creek at two locations: 0.25 miles upstream from the mouth in a tidal reach, and in close proximity to a bridge four miles east of Byron (Curtis 1942).
