“…These benefits for early seedling growth are similar to those previously reported for lyme grass in a short term field study (Enkhtuya et al 2003). However, commensal and parasitic responses of AMF inoculated plants, initiating in the second summer, show that the AMF treatments failed to provide continued plant benefits.…”

“…These experiments have shown that young lyme grass seedlings can respond responsively to AMF inoculation. Enkhtuya et al (2003) showed that survival and growth of first year lyme grass seedlings in Icelandic deserts was enhanced by AMF inoculation and Greipsson and El-Mayas (2000) found a similar mycorrhizal benefit in a pot study. These encouraging results led to the establishment of a large field experiment to help realize the potential benefits of AMF inoculation in lyme grass field establishment and to investigate if other inputs and costs could be reduced.…”

“…The present study employed the same isolate mixture as used by Enkhtuya et al (2003) in which two of the isolates, G. hoi and G. claroideum, originated from lyme grass dunes in Iceland. Greipsson and El-Mayas (2000) also used native AMF from lyme grass dunes in Iceland in a pot study and found that these were better at enhancing lyme grass early growth than commercial AMF inoculum.…”

The potential benefits of artificial inoculation with arbuscular mycorrhizal fungi (AMF) for lyme grass seedling establishment were tested in combination with varying fertilizer and seed rates in a long term revegetation study in two sandy deserts in Iceland. Fertilizer inputs proved more effective than other treatment variables in increasing vegetative growth, flowering and sand accretion of lyme grass seedlings. For this, re-fertilization was more important than the initial dose. AMF inoculation initially improved seedling growth but after the first year the effects became neutral or negative. While fertilization generally reduced AMF colonization, the negative effects of inoculation on lyme grass were enhanced by fertilization. Larger seed doses raised inter-and intraspecific competition, decreasing lyme grass vegetative regeneration and associate vegetation. Based on the current results, the application of AMF inoculation cannot be recommended for lyme grass establishment at the present. However, low seed rates (≤50 seeds m -2 ) and low initial fertilizer doses (≤10 g m -2 ) in combination with moderate re-fertilization application rates for a few years are apparently economical for the establishment of lyme grass for revegetation projects.

“…Greipsson and El-Mayas (1999) used aerial seeding to establish F. rubra in barren Icelandic lands which failed to produce a long-lasting cover, failure that was attributed by the authors to the lack of mycorrhizal propagules in the reclamed soil. The use of AMF inocula has been shown to increase the plant growth and cover in the same Icelandic conditions (Enkhtuya et al, 2003), however, the difficulty of adequately inoculating large areas remains a problem. The integration of the AMF inoculation with the hydroseeding technique might permit the use of mixtures of native grasses and legumes, enhancing their growth and successful competition with non-mycorrhizal ruderals thus speeding the restoration process.…”

Hydroseeding is a technique increasingly used to establish vegetation on large degraded areas, such as large-scale road construction sites and quarries. Native grasses and legume species are used on rehabilitation and restoration projects as a first step in the recovery of such places, prior to the establishment of native forbs and shrubs that occurs at a slower pace. The effect of mycorrhizal inoculation on the development of nine species of grasses and legumes that can be potentially used in restoration processes in the Mediterranean area was studied, in microcosm experiments under greenhouse conditions. The effect of adding arbuscular mycorrhizal (AM) inoculum to a hydroseeding mixture was also investigated in greenhouse and in field conditions. In the hydroseeding experiments the mycorrhizal inoculum was added to the seed slurry in a jet agitated hydroseeding machine and sprayed to the soil surface with a pressurised spray in a one-step application. The study shows that Glomus intraradices Schenk & Smith BEG72 is able to establish the symbiosis when applied at sowing while Glomus mosseae (Nicol. & Gerd.) Gerdemann & Trappe BEG116 is not. It also confirms that legumes are more highly mycotrophic than grasses. The results of the hydroseeding experiments demonstrate the establishment of the symbiosis using this technology, both in the greenhouse and in the field. Mycorrhizal inoculation improved above ground plant growth and increased the legumes/grasses ratio.

“…This in turn attracts a variety of birds. Birch also has a number of fungi associated with it, especially beneficial soil mycorrhizal fungi that help to make the birch plants healthier and more resistant to insect herbivory, both above and below ground (Enkhtuya et al 2003;Oddsdóttir et al 2010). Birch is clearly vital to the viability and productivity of the tundra and forest ecosystems.…”
