H. St. John, 1920) in Lough Arrow, a premier trout angling lake in the north-west of Ireland, designated as a Natura 2000 site (Special Area of Conservation (Annex I habitat, “Hard oligo-mesotrophic waters with benthic vegetation of Chara spp.”) and Special Protection Area for birdlife). The aim of this study was to manage E. nuttallii, a relatively recent arrival to this lake, while simultaneously promoting rehabilitation of native charophytes. The trial was carried out in Loughbrickbay, one of the lough’s primary boating launch sites, an area determined as highly infested with E. nuttallii. Two experimental areas covering a total of 800 m² were treated by covering the invasive weed and substrate with jute textile, a single and double layer respectively. The trial was successful in controlling E. nuttallii for both single (P = 0) and double layer treatments (P = 0.002). The treatments applied resulted in a reduction of the mean percentage cover of the invasive species by > 60% for both treatments. Post-treatment mean percentage cover of E. nuttallii did not exceed 6% for either treatment. Furthermore, the mean percentage cover of indigenous charophyte flora present pre-treatment was not significantly impacted by the application of jute in either the single (P = 0.165) or double treatment (P = 0.353). For biosecurity purposes, the treatment areas were strategically positioned in close proximity to the bays pier and slipway. The treated transects were marked with navigational buoys to provide a corridor for boats entering and exiting the lake, which help to contain the invasive within the Natura 2000 site while reducing the spread risk via this pathway to other sites vulnerable to infestation.

A novel approach to aquatic weed control and habitat restoration using biodegradable jute matting / Joseph M. Caffrey in Aquatic invasions, 5 (2) (2010) 

Public Citation [article]  inAquatic invasions > 5 (2) (2010) . - 123-129 Titre : A novel approach to aquatic weed control and habitat restoration using biodegradable jute matting Type de document : Imprimé Auteurs : Joseph M. Caffrey ; Michael Millane ; Stéphanie Evers ; Helen Moran ; Martin Butler Année de publication : 2010 Article en page(s) : 123-129 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Lagarosiphon major (Ridl.) Moss, 1928 Résumé : This technical paper presents results from pilot field trials conducted on the novel use of a biodegradable jute material to eradicate the highly invasive aquatic macrophyte Lagarosiphon major Ridley from Lough Corrib, Ireland. The results demonstrate the ability of the jute material to comprehensively kill L. major and to restore native macrophyte communities to areas of the lake that were previously overgrown with this priority invasive species. To date, eight indigenous plant species (four charophytes and four angiosperms) have been recorded growing through the loose-weave jute fabric. However, no Lagarosiphon has been recorded as doing so. This material has the potential for broader application in the management of nuisance aquatic weeds and in the restoration of native flora extirpated by these alien species.
