tree mallow การใช้

• Tree mallow, orache, common scurveygrass, rock sea spurrey and sea beet have all been recorded.
• Flora on the Channel Islands include a unique subspecies of pine, oak, and the island tree mallow.
• Similar measures have been undertaken at the Anglesey tern colonies along with clearance of vegetation, in particular Tree Mallow.
• Tree mallow was considered a nutritive animal food in Britain in the 19th century, and is still sometimes used as animal fodder in Europe.
• Puffin and gulls also breed on the island and plants recorded are tree mallow, sea beet, rock sea-spurrey, common scurvygrass and orache.
• Plants recorded are tree mallow, thrift, sea beet, rock sea spurrey, common scurvy grass, orache and English stonecrop ( " Sedum anglicum " ).
• These walled areas have enabled a build-up of soil and the establishment of vegetation, notably tree mallow ( " Lavatera arborea " ), which provides nesting cover for the birds.
• Lousley recorded common scurvygrass ( " Cochlearia officinalis " ), tree mallow and a species of orache ( " Atriplex " spp ) although flowering plants are not a permanent feature.
• The tree mallow's recent increased range among Scottish islands has raised concerns that it is displacing native vegetation, and is reducing Atlantic puffin ( " Fratercula arctica " ) populations in affected areas.
• While sometimes detrimental to seabird habitat, management of tree mallow ( both planting and thinning ) has been successfully employed to shelter nesting sites of the threatened roseate tern, which requires more coverage than common terns to impede predation.
• Puffin numbers on the island of Craigleith, once one of the largest colonies in Scotland with 28, 000 pairs, have declined dramatically to just a few thousand due to the invasion of a large introduced plant, the tree mallow ( " Lavatera arborea " ).
• On the north-west side of the island there is an area of maritime grassland with abundant thrift ( " Armeria maritima " ), sea beet ( " Beta vulgaris subsp . maritima " ) and tree mallow ( " Lavatera arborea " ).
• Terns interchange regularly between all three sites, and form part of a larger Irish Sea tern population together with birds at sites in Ireland such as management measures they have undertaken here include control of introduced tree mallow ( " Lavatera arborea " ) and provision of nestboxes; these measures as aimed particularly at helping to increase the attractiveness of the site to breeding roseate terns, although it is accepted that the future number of pairs of this species here is primarily dependent on the overall health of the Irish Sea population.
