  • "National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
    Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment.

Shearman May 2016 Accepted by: Dr. G. Geoff Wang, Committee Chair Dr. Saara J. DeWalt Dr. Donald L. Hagan Dr. Julia L. Kerrigan Dr. William C. Bridges ABSTRACT Laurel Wilt Disease (LWD) has caused severe mortality in native Persea species of the southeastern United States since it was first detected in 2003. This study was designed to document the range-wide population impacts to LWD, as well as the patterns of mortality and regeneration in Persea ecosystems. I used Forest Inventory and Analysis (FIA) data from the U.S. Forest Service to estimate Persea borbonia (red bay) populations from 2003 to 2011 to see if any decline could be observed since the introduction of LWD causal agents.

  • Floristic Composition and Species Richness of Subtropical Seasonally Wet Muhlenbergia Sericea Prairies in Portions of Central and South Florida Steve L
    Floristic Composition and Species Richness of Subtropical Seasonally Wet Muhlenbergia sericea Prairies in Portions of Central and South Florida Steve L. Orzell Avon Park Air Force Range, 29 South Blvd., Avon Park Air Force Range, FL 33825-5700 [email protected] Edwin Bridges Botanical and Ecological Consultant, 7752 Holly Tree Place, NW, Bremerton, WA 98312-1063 [email protected] ABSTRACT Fire-maintained, species-rich, seasonally wet subtropical grasslands dominated by muhly grass (Mu- hlenbergia sericea ), here referred to as calcareous wet prairies, occur on mineral soils between pine- lands (or Florida dry prairies) and herbaceous wetlands. Southern Florida calcareous prairies/pinelands are described based upon species composition, species richness, niche or habitat breadth, taxonomic uniqueness, and geographic area. This study differentiated three calcareous prairie/pineland regions, central, south-central, and south Florida. A south-central Florida community type occurs sporadically from Polk County south to Okeechobee, Hendry, and Sarasota counties, in an otherwise acidic prairie/ pineland landscape. Quantitative sampling using nested and non-nested modules in Polk and Okeechobee counties was utilized to determine fine-scale species richness values. Results indicate that these prairies have among the highest fine-scale vascular plant species richness values recorded in North America, up to 27 species in 0.1 m2, 49 species in 1 m2, and 171 species in 1000 m2. Floristic lists compiled from 43 sites in 14 southern Florida counties demonstrate that many sites have biodiversity significance with over 100 species. Several have 140-180 species recorded from single-event visits. The community species pool consists of 412 taxa from south-central Florida calcareous prairies alone with 548 taxa when south Florida calcareous pineland/prairies are included.

K. M. GOLAM SARWAR AND HIDEKI TAKAHASHI Laboratory of Systematic Botany, Graduate School of Agriculture, Hokkaido University, Japan Keywords: Pollen morphology; Exine sculpture; Phyllodoceae; Taxonomic significance. Abstract Pollen morphology of 13 taxa belonging to 5 genera of the tribe Phyllodoceae (Ericaceae) was examined by means of light and scanning electron microscopy (LM and SEM, respectively), or SEM alone. In Phyllodoceae, 3-colpor(oid)ate, minute to medium, oblate pollen grains are united usually in tetrahedral tetrads. Pollen tetrads are generally characterized by the presence of viscin threads except Elliottia pyroliflora, Epigaea asiatica and Phyllodoce caerulea. The absence of viscin threads might indicate to a secondary loss, since these are present at least in some species within all the genera of Phyllodoceae. The pollen morphological data confirm the infra- and inter-generic relationships as identified by molecular phylogeny of Phyllodoceae and/or vice-versa. Although various palynological characters were found to be taxonomically important at different taxonomic levels, the apocolpial exine sculpture is emerged as one of the most important palynological features of systematic importance.
