Aquatic Plant Project

The Aquatic Plant Project was launched in 2019 across Ireland with the aim of improving aquatic plant identification skills and increase recording. This included a huge campaign of training and recording days, resulting in thousands of new records. We continued the project in 2020 and  2021, and funding has now been received for 2022 with new opportunities for people to learn about aquatic plants and get involved with recording. Webinars are recorded and the videos are free to view on the Aquatic Plant Project playlist.

The 2022 programme

The 2022 programme includes three webinars presented Nick Stewart. Each presentation will be followed by a question and answer session, using the Zoom Q&A feature, and then by a short additional talk. The first seminar in June was an Introduction to Broad-leaved Pondweed ID, which is now available to watch online, along with a shorter talk on Preservation of aquatic plant specimens.  On 2nd July the webinar included an Introduction to Narrow-leaved Pondweed ID and How to make a grapnel. These will be available online shortly. The next seminar is now available to book online (free of charge):

The next field days in the Aquatic Plant Project programme will be as follows (click link to book your place online):

The aim of the days is to improve identification skills and gather records in a range of aquatic habitats. Everyone is very welcome but booking is essential. Thanks to the generous funding from the Irish National Parks & Wildlife Service the events are free.

The first two field days of the 2022 programme were held over the last weekend in May. On the Saturday, aquatic plant expert Nick Stewart and County Recorder, Cliona Byrne led a group of 9 botanists along the Rivers Dee and Glyde in Louth. And on the Sunday, Nick and County Recorder, Margaret Norton led 18 botanists on the banks of the River Boyne and the Boyne Canal in Co. Meath.

The 2021 programme

  • Our first event was a sedge & wetland plant training day on the 2nd July, led by John Faulkner, visiting sites on the Cavan - Monaghan border.
  • We held a webinar on Water-starwort Identification on the 5th July. It covered all Water-starworts (Callitriche spp.) you are likely to encounter in Ireland - and Britain! Watch the video.
  • On 10th July we learned how to identify Water-crowfoots. Watch the video.
  • On 28th July we held a field aquatic plant training day with Cilian Roden & John Conaghan. We visited a site southwest of Carraroe, Connemara, Co. Galway to look for and survey Najas flexilis (Slender Naiad), and learnt how to identify pondweeds (Potamogeton spp.) and other aquatic species - including Potamogeton alpinus (Red Pondweed).
  • Our aquatics expert Nick Stewart led field training sessions in Cork, 21st-23rd August; in Waterford, 28th-29th August; and in Co. Kilkenny (in the Inistoge-Thomastown area) on 30th August.
  • The final event of 2021 was an Introduction to Broad-leaved Pondweeds webinar by Nick Stewart on the 23rd October.

The 2020 programme

We held two webinars led by aquatic plant expert Nick Stewart on Aquatic Plant Identification in 2020:

  • Introduction to Aquatic Plant Identification. This webinar covered the main growth forms of aquatic plants, the key features you need to consider, resources to help with identification, and equipment used for sampling. Watch the recording. View the slides.
  • Stonewort Identification. Charophytes, or Stoneworts, are complex aquatic green algae which can be tricky to identify, but Nick will guide us through the process. Watch the recording. View the slides.

We also ran our first ever online workshop Aquatic Plant Identification. Nick led a virtual workshop where he went through the process of identifying specimens live using a camera and digital microscope to show key features, and participants were able to ask questions throughout. Some participants even sent specimens to Nick in advance which were used during the session. The workshop was a big success and a great learning opportunity for organisers and attendees alike! We aren't able to share this one online, but are looking to offer more similar opportunities in the future.

Training in Northern Ireland - 2020

Thanks to funding from CEDaR, Nick Stewart to Northern Ireland for a week of work in the Ulster Museum Herbarium in February, where he worked through their collection of aquatic plant specimens and provided small group mentoring to five experienced botanists and recorders. This was followed by an aquatic plant identification workshop at Lough Neagh Discovery Centre, Oxford Island Co. Armagh. While February might not seem like the ideal time to study aquatic plants, 16 people came along for an interesting and informative day, which provided excellent preparation for a summer of recording!

The 2019 programme

The Aquatic Plant Project in 2019 was a huge success, training over 100 people in aquatic plant identification and collecting 6397 aquatic plant records, including 370 new hectad records. In total the project visited 239 sites in 97 hectads across 27 vice-counties.

A huge thanks for this success is due to Paul Green for managing the project, Nick Stewart, Chris Preston, Cillian Roden, and Lynda Weekes for running training and recording days, and of course to the National Parks and Wildlife Service (RoI) and the Centre for Environmental Data and Recording (NI) for their generous funding.
