Abstract Plants have always excited interest because of their active principles that could be a source of healing in various affections. The aim of this study was to demonstrate that the hepatoprotective and antimicrobial effects of Lycopodium clavatum and Equisetum arvense from the Western parts of Romania (Arad County) are not as pronounced as described in literature, against xenobiotic intoxication or microbial infection.

  • Species Almanac • Nature Activities At
    The deeriNature Almanac What is the i in deeriNature? Is it information, internet? How about identification. When you go out on the Deer Isle preserves, what species are you almost certain to encounter? Which ones might you wish to identify? Then how do you organize your experience so that learning about the nearly overwhelming richness of nature becomes wonderfully satisfying? A century ago every farmer, medicine woman, and indeed any educated man or woman felt that they should have a solid knowledge of the plants around them. The Fairbanks Museum in St. Johnsbury, Vermont has maintained a Flower Table with labeled specimens since 1905. The Deer Isle-Stonington Historical Society has an antique herbarium collection made by Ada Southworth, a Dunham’s point rusticator. Today there are lovely field guides galore but the equivalent of a local list can come to you now by digital download. Here is an almanac, a list of likely plant and animal species (and something about rocks too) for our Deer Isle preserves, arranged according to season and habitat. Enjoy this free e-Book on your desktop, tablet or smartphone. Take this e-book with you on the trails and consult the Point of Interest signs. If you have a smartphone and adequate coverage, at some preserves a QR code will tell you more at the Points of Interest. After each category on the lists you will find suggestions for books to consult or acquire. You will have to read the on line reviews for apps as that field is developing too rapidly for any other approach.

Vol. 21, No. 2., 357–372, 2012, Zagreb. The process of urbanization is one of the most extreme forms of anthropogenic habitat modifica- tion. Negative trends and their effects on the one hand, and concern for the preservation of bio- diversity and quality of city life on the other, are the initiators of urban flora research. The flora of urban areas in Croatia has not been the subject of sustained research and therefore floristic records for most of the larger cities are unknown. The research area is located in northwest Croatia in the city of Zagreb, on the right bank of the Sava River. In the area of Konopljenka and Pi{korovo a total of 351 taxa of vascular plants belonging to 81 families were recorded. Seven of them (2%) were pteridophytes (Equisetidae), two of them (0.6%) gymnosperms (Pinidae), and others were angio- sperms (Magnoliidae). Among angiosperms, 71 taxa (20.2%) belong to monocotyledons (superorder Lilianae) and the other 271 taxa (77.2%) from 65 families belong to other superorders of angio- sperms.

Although only in the Horsetails early stages of establishment, these weeds have the potential to seriously degrade Australia’s ecosystems. – Equisetum The popularity of interesting foliage plants for landscaping in Australian gardens is contributing to a local increase in horsetails, which are among the world’s worst weeds. Several species are species being sold for use in Australian gardens. Horsetails produce inhibitory substances that can depress the growth of neighbouring plants at high densities.

  • Ferns of the National Forests in Alaska
    Ferns of the National Forests in Alaska United States Forest Service R10-RG-182 Department of Alaska Region June 2010 Agriculture Ferns abound in Alaska’s two national forests, the Chugach and the Tongass, which are situated on the southcentral and southeastern coast respectively. These forests contain myriad habitats where ferns thrive. Most showy are the ferns occupying the forest floor of temperate rainforest habitats. However, ferns grow in nearly all non-forested habitats such as beach meadows, wet meadows, alpine meadows, high alpine, and talus slopes. The cool, wet climate highly influenced by the Pacific Ocean creates ideal growing conditions for ferns. In the past, ferns had been loosely grouped with other spore-bearing vascular plants, often called “fern allies.” Recent genetic studies reveal surprises about the relationships among ferns and fern allies. First, ferns appear to be closely related to horsetails; in fact these plants are now grouped as ferns. Second, plants commonly called fern allies (club-mosses, spike-mosses and quillworts) are not at all related to the ferns. General relationships among members of the plant kingdom are shown in the diagram below. Ferns & Horsetails Flowering Plants Conifers Club-mosses, Spike-mosses & Quillworts Mosses & Liverworts Thirty of the fifty-four ferns and horsetails known to grow in Alaska’s national forests are described and pictured in this brochure. They are arranged in the same order as listed in the fern checklist presented on pages 26 and 27. 2 Midrib Blade Pinnule(s) Frond (leaf) Pinna Petiole (leaf stalk) Parts of a fern frond, northern wood fern (p.

  • Native Plant List, Pdf Format
    Appendix A: City of Bellingham Native Plant List December 2020 The City of Bellingham Native Plant List (Figure 1) includes plant species that are native to Bellingham watersheds (Figure 2). The native plant list applies to all habitat types, including riparian, upland, and wetland areas. The list was developed using specimen records from the Consortium of Pacific Northwest Herbaria and Bellingham plant checklists curated by Don Knoke, a volunteer at the University of Washington Herbarium. To improve plant establishment and protect the genetic resources of our local plant populations, the City recommends using native plants that were grown from seeds or cuttings collected from the Puget Trough Ecoregion (Figure 3). Obtaining native plants grown from material collected from the Puget Trough Ecoregion will help ensure the plants are adapted to the unique environmental conditions of Bellingham watersheds and are genetically similar to our local plant populations. A more thorough discussion of the rational and selection process is provided in the City of Bellingham Public Works Department Native Plant Materials Selection Guidelines, December 2020. Figure 1.
