Wetlands of New Jersey National Wetlands Inventory JULY 1985 WETLANDS OF NEW JERSEY u.s. Department of the Interior Fish and Wildlife Service WETLANDS OF NEW JERSEY by Ralph W. Tiner, Jr. U.S. Fish and Wildlife Service Region 5 Habitat Resources One Gateway Center Newton Comer, MA 02158 JULY 1985 This report should be cited as follows: Tiner, R.W., Jr. 1985. Wetlands of New Jersey. U.S. Fish and Wildlife Service, National Wetlands Inventory, Newton Comer, MA. 117 pp. Acknowledgements Many individuals and organizations have contributed to the successful completion ofthe wetlands inventory in New Jersey and to the preparation of this report. The Service's National Wetlands Inventory Group in St. Petersburg, Florida provided technical support for producing the wetland maps and for constructing the New Jersey wetland database. The U.S. Army, Corps of Engineers, New York District (Passaic River Basin Study Group) and the N.J. Department of Environmental Protection, Division of Coastal Resources (Coastal Planning and Development) contributed funds to complete mapping in northern New Jersey and to digitize wetland maps along the coast, respectively. The N.J.D.E.P. Office of Environmental Analysis provided space and equipment for conducting the photo interpretation phase of the inventory. Special attention and appreciation is given to Larry Vinzant who performed nearly all of the photo interpretation. His work serves as the foundation of this report. I also thank John Organ, my former assistant, for his help in providing quality control of interpreted photos and draft maps and in reviewing the draft of this report. The efforts of Bill Zinni in completing photo interpretation (Frankfort and Lumberville maps), preparing Figures 14 and 22, and reviewing parts of the draft manuscript are also appreciated.

  • Alternative Stable States of Tidal Marsh Vegetation Patterns and Channel Complexity
    ECOHYDROLOGY Ecohydrol. (2016) Published online in Wiley Online Library (wileyonlinelibrary.com) DOI: 10.1002/eco.1755 Alternative stable states of tidal marsh vegetation patterns and channel complexity K. B. Moffett1* and S. M. Gorelick2 1 School of the Environment, Washington State University Vancouver, Vancouver, WA, USA 2 Department of Earth System Science, Stanford University, Stanford, CA, USA ABSTRACT Intertidal marshes develop between uplands and mudflats, and develop vegetation zonation, via biogeomorphic feedbacks. Is the spatial configuration of vegetation and channels also biogeomorphically organized at the intermediate, marsh-scale? We used high-resolution aerial photographs and a decision-tree procedure to categorize marsh vegetation patterns and channel geometries for 113 tidal marshes in San Francisco Bay estuary and assessed these patterns’ relations to site characteristics. Interpretation was further informed by generalized linear mixed models using pattern-quantifying metrics from object-based image analysis to predict vegetation and channel pattern complexity. Vegetation pattern complexity was significantly related to marsh salinity but independent of marsh age and elevation. Channel complexity was significantly related to marsh age but independent of salinity and elevation. Vegetation pattern complexity and channel complexity were significantly related, forming two prevalent biogeomorphic states: complex versus simple vegetation-and-channel configurations. That this correspondence held across marsh ages (decades to millennia)

  • Recommended Urban Trees Wilmington, De Area (Usda Hardiness Zone 7)
    RECOMMENDED URBAN TREES WILMINGTON, DE AREA (USDA HARDINESS ZONE 7) BEFORE PLANTING: THINGS TO REMEMBER! • Street trees provide many benefits beyond beautification of our neighborhoods and city. They can reduce cooling costs in summer, improve property values, attract residents and businesses, and revitalize communities. Contact the Delaware Center for Horticulture to learn more about the many benefits of urban trees and to get involved with your own neighborhood street tree project, for further recommendations, or to request a new Wilmington street tree through the DCH Tree Program. • The approval of a Wilmington Street Tree Permit is required before planting any tree in the public right-of-way (generally determined as between the sidewalk and the curb, in a tree lawn, grass strip or tree pit in sidewalk). According to the Wilmington City Code, Chapter 46 (Vegetation), street tree maintenance is the responsibility of the respective property owner. Contact the Delaware Center for Horticulture or the Wilmington Department of Public Works for a permit form or for more information. • The selection of an appropriate street tree is essential to its success. Criteria such as soil space, underground or overhead utilities, sidewalk and curbing considerations, ultimate size, tolerance of urban conditions, and general species information must be considered before selecting a street tree for planting. Proper care during establishment of a young tree is also crucial and can reduce the need for costly maintenance in the future. • Many popular trees do not appear on this list for a variety of reasons. The Delaware Center for Horticulture does NOT recommend nor approve the planting of Callery pear cultivars (Pyrus calleryana, e.g.

  • Present-Day Genetic Structure of the Holoparasite Conopholis Americana

All rights reserved. 1058-5893/2016/17702-0003$15.00 DOI: 10.1086/684180 PRESENT-DAY GENETIC STRUCTURE OF THE HOLOPARASITE CONOPHOLIS AMERICANA (OROBANCHACEAE) IN EASTERN NORTH AMERICA AND THE LOCATION OF ITS REFUGIA DURING THE LAST GLACIAL CYCLE Anuar Rodrigues1,* and Saša Stefanović* *Department of Biology, University of Toronto, Mississauga, Ontario L5L 1C6, Canada Editor: Félix Forest Premise of research. Understanding how various organisms respond to previous changes in climate could provide insight into how they may respond or adapt to the current changes. Conopholis americana has a broad distribution across eastern North America, covering both previously glaciated and unglaciated regions. In this study, we investigated the postglacial history and phylogeographic structure of this parasitic plant spe- cies to characterize its genetic variation and structure and to identify the number and locations of refugia. Methodology. Molecular data from 10 microsatellite markers and DNA sequences from the plastid gene/ introns (clpP) were obtained for 281 individuals sampled from 75 populations spanning the current range of the species in eastern North America and analyzed using a variety of phylogeographic methods. Distribution modeling was carried out to determine regions with relatively suitable climate niches for populations at the Last Glacial Maximum (LGM) and present. Pivotal results. We inferred the persistence of a minimum of two glacial refugia for C. americana at the LGM, one in north-central Florida and southern Alabama and another in the Appalachian Mountains near the southern tip of the Blue Ridge Mountains.

  • Aquatic Vascular Plant Species Distribution Maps
    Appendix 11.5.1: Aquatic Vascular Plant Species Distribution Maps These distribution maps are for 116 aquatic vascular macrophyte species (Table 1). Aquatic designation follows habitat descriptions in Haines and Vining (1998), and includes submergent, floating and some emergent species. See Appendix 11.4 for list of species. Also included in Appendix 11.4 is the number of HUC-10 watersheds from which each taxon has been recorded, and the county-level distributions. Data are from nine sources, as compiled in the MABP database (plus a few additional records derived from ancilliary information contained in reports from two fisheries surveys in the Upper St. John basin organized by The Nature Conservancy). With the exception of the University of Maine herbarium records, most locations represent point samples (coordinates were provided in data sources or derived by MABP from site descriptions in data sources). The herbarium data are identified only to township. In the species distribution maps, town-level records are indicated by center-points (centroids). Figure 1 on this page shows as polygons the towns where taxon records are identified only at the town level.
