Projects

Ecological Surveying Projects

Envirico was contracted by National Parks and Wildlife to carry out burrow nesting breeding seabird surveys and produce a publication standard report.

Our team of ecologists conducted Manx Shearwater, Storm Petrel and Puffin surveys on remote islands off the South-west coast of Ireland during the summer of 2019.

Envirico was contracted by National Parks and Wildlife to assess the impacts of fires on the Killarney National Park and produce a publication standard report.

Our team of ecologists conducted bird surveys, invertebrate sampling, woodland surveys, upland surveys, grassland surveys and wetland surveys in burnt and unburnt areas of the Killarney National Park.

Japanese Knotweed Remediation Projects

In 2017, Envirico was contracted by Mott MacDonald on behalf of Wexford County Council to carry out an Invasive Alien Species Management Plan for the footprint of the proposed Enniscorthy Flood Defence Scheme and the treatment of Himalayan Balsam, Japanese Knotweed and Giant Hogweed present on the banks of the River Slaney.

In total Himalayan Balsam covered an area of 75,534 square metres.

Envirico was contracted by a private construction company to carry out a Japanese Knotweed Management Plan and treatment of Japanese Knotweed for a Social Housing Development Project at Carrick on Suir, County Tipperary.

Envirico excavated all Japanese Knotweed contaminated material during the course of the works and placed the excavated Japanese Knotweed material into securely sealed root barrier membrane cells to a depth of 2m below the finished ground surface in accordance with best-practice. Cell depths varied in range from 4m to 6.5m. A total of 1850 cubic metres of Japanese Knotweed contaminated material was excavated and buried.

The outcome of this project was the successful and complete removal of Japanese Knotweed therefore allowing the Construction Company to complete their project.

Envirico was contracted by a private construction company to carry out a Management Plan and the treatment of Japanese Knotweed on a Housing Development Project Site in Stepaside, County Dublin.

Envirico ecologists excavated all Japanese knotweed contaminated soil on-site and transferred all the contaminated soil, by covered truck, into a root barrier membrane lined cell on another section of the site. This process has high bio-security in order to prevent the spread of Japanese knotweed.

The Japanese knotweed contaminated material is unable to grow through the root barrier membrane lined cell. Envirico’s protocol includes continuous monitoring for Japanese knotweed regrowth for a five-year period from the date of the remediation works.

Envirico was contracted by Comharchumann Dún Chaoin to eradicate two invasive alien species; Japanese Knotweed and Giant Rhubarb from the local area.

Dún Chaoin comprises an area of approximately 2,790 acres at western end of the Dingle Penisula. There are three main watercourses in the area, which are the main carriers of the Japanese knotweed. There is approximately 27,059 square metres of Japanese knotweed being treated. The methods of treatment being undertaken consist of stem injection and herbicide spraying for the Japanese knotweed and leaf wiping for the Giant Rhubarb.

Our experienced, qualified ecologists conduct this ongoing herbicide treatment programme with best practice guaranteed.

Envirico was contracted by Glenmann Bro.’s to carry out a Japanese Knotweed Management Plan and the treatment of Japanese Knotweed for a Housing Development Project in Tuam, Co. Galway.

The method best suited for this site was to excavate all Japanese knotweed on-site and encapsulate in a fully sealed root barrier membrane cell
