  • A note from the editor
    Have a nice summer and welcome to Botany News!  I hope you will enjoy the material and I welcome feedback from you.  If you like this new e-zine you could let your botanical friends know about it.  Some of you are already signed up for receiving Botany News.  I am pleased to see that readers of Botany News and the website come from all over the world!  During the past year our readers have come from over twenty European countries, more than ten countries of North, South and Central America, quite a few Asian countries, two African countries and both Australia and New Zealand.  I welcome you all!  I have already received some suggestions from readers on material for this e-zine.  Why not send me your letters and articles to be published in Botany News and share your joy of plants with readers worldwide?  Perhaps, you have your own website on plants, if so contact us for possible link exchange.


  • The aquatic plants of Iceland
    Ponds and streams are often well suited for plant and animal life.  On Reykjavik Pond, Tjörnin, there are Mallards (Anas platyrhynchos), other ducks, and Whooper Swans (Cygnus cygnus).  In the vicinity of the city, there is Ástjörn a pond with several characteristic aquatic species and further outsite Reykjavik there are many lakes and ponds. 

    Everywhere in ponds and on lake banks there are emergent, submerged and floating aquatic plants.  Ponds are often situated in wetlands, where you find plant species such as Narrow Smallreed (Calamagrostis stricta), the tiny Northern bedstraw (Galium boreale), Tea-leaved Willow (Salix phylicifolia) and the colourful Marsh Violet (Viola palustris).

    Commonly by pond banks and shallow ponds, you find the yellow-flowered Marsh Marigold (Caltha palustris), Marsh Cinquifoil (Potentilla palustris), Garden Angelica (Angelica archangelica), and grasses such as Orange Foxtail (Alopecuris aequalis) and Fiorin (Agrostis stolonifera). Robust sedges such as Lyngebye's Sedge (Carex lyngbyei) and Beaked Sedge (Carex rostrata) grow on lake banks, while the thread-formed Arctic Rush (Juncus arcticus) and Common Cottongrass (Eriophorum angustifolium) form large mats or smaller tufts.  Tall pond bank vegetation is an excellent place for various ducks and waders to hide.

    In lowland marshes and shallow ponds you may find the delicate Whorl-grass (Catabrosa aquatica) and more rarely the large Floating Sweet-grass (Glyceria fluitans).  Nesting near the ponds, there are ducks, phalaropes, and grebes.  On a quiet early morning you may hear the song of the Common Loon (Gavia immer). 

    On muddy soils, in wet meadows and shallow ponds in South Iceland you will see the occasional Water Speedwell (Veronica anagallis-aquatica), while the puny, white-flowered Starwort Mouse-ear (Cerastium cerastoides) and Common Spike-rush (Eleocharis palustris) grow on pond banks. 

    The true aquatic plants, the pondweeds (Potamogeton) and bur-reeds (Sparganium), are found deeper in the pond.  Pondweeds often have leaves floating in the surface, while the plants remain attached on their long stem.  Submerged water-milfoils (Myriophyllum) are found even further out in the pond water.  In the water surface, there are free-floating species such as the Lesser Bladderwort (Utricularia minor), a mysterious insect–eating plant, and swarms of tiny algae and bluegreen bacteria. 

  • Green Tabloid – Speaking of acid rain
    Industry and cars are a part of our modern existence.  However,
    there is a constant need to try to control and minimize our impact on the living environment and the world's precious water resources.  
    Although, industries and cars are now equipped with improved technology to reduce the adverse effects of pollution, the impact of car pollution and industrial activities is increasing.  One of the consequences of industrial and car emissions is the rising concentration of sulphur dioxide in the air we breathe. Sulphur dioxide contributes to the formation of acid rain.  In turn, acid rain may cause local pollution or be carried with prevailing wind systems to remote areas.  In the cities of Europe and North America acid rain changes the appearance of trees by destroying the delicate epiphytic lichens.  Acid rain also leaves scars by eroding the stones of buildings and art work.  While the effects of acid rain and other pollution is often pronounced in cities, the destructive effect of acid rain often reach

  • The Flower Box
    Iceland is a good place to explore nature and wildlife.  Consider e. g. Whale and Puffin watching, a day to remember at the Blue Lagoon or plan to explore the Icelandic flora by joining our Botanical Tours in Iceland.  We are now accepting bookings for the summer so fill in the order form!  You can also contact us in advance if you have any enquiries.  Updated information on the tours is published in this section.  If you wish to participate and are planning a trip to Iceland contact us well in advance.
