  • "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.

  • Conocarpus Erectus
    Conocarpus erectus (Button Mangrove, Green Buttonwood) Button mangrove is a broadleaf evergreen trees which can withstand drought, salt, heat and high winds.The fruit looks like a dried raspberry or a pine cone. Its flaky brown bark is very attractive. Throughout the year, greenish-white and purple flowers are produced, but they are not noticeable. Due to the high tolerance of heat and drought it is used a lot in hot and arid climate as hedge, street tree or windbreak.

Samples were collected from four sampling sites representing area of high traffic density, area future away from traffic and Industrial area. Samples were collected in two stages (May and October) in 2011 for chemical analysis. Samples from village near the city also analyzed for comparison. Based on the results, the stages of leaf sampling did not showed any significant effect on the concentration of the measured heavy metals in leaf samples. Chemical analysis of soil samples at depth of 0-10cm showed that concentration of most of these elements was lower than the maximum recommended levels. Concentrations of measured heavy metals in washed leaves were lower than those of unwashed leaves of Conocarpus and different was significant. In spite of that, there was no significant correlation between the concentrations of heavy metals in washed leaves and soil samples.

  • Environmental Effects of Stump and Root Harvesting
    Research Note Environmental effects of stump and root harvesting Andy Moffat, Tom Nisbet and Bruce Nicoll September 2011 The removal of tree stumps and coarse roots from felling sites as a source of woody biomass for bioenergy generation is well established in parts of Europe, and interest has been expressed in replicating this practice in some regions of the UK. Overseas research shows that stump harvesting can pose a risk to sustainable forest management, unless care is taken in site selection and operational practice. Poor practice can lead to detrimental effects on soil structure, increasing the risk of soil erosion, and depletes soil nutrient and carbon capital. Stump and root harvesting can also have impacts on woodland biodiversity, archaeological heritage and tree health. This Research Note offers a synthesis of available evidence on the effects of stump harvesting, drawn from largely overseas sources but critically considered for their applicability to British conditions. The overall environmental effects of stump harvesting on forest sites in the UK, and the relative magnitude of these effects compared with conventional restock site preparation, are under ongoing investigation. The results will be used to develop more definitive guidance. Preliminary guidance published by Forest Research sets out how the risks of potential damaging effects can be minimised, notably by careful assessment of site suitability and location of activities on low risk sites. It is recommended that this is used to guide the planning and location of stump and root harvesting operations in Britain.

To date, the development of new antimicrobial drugs is still lagging far behind the rising demand, partly owing to the absence of an effective screening platform.
