There are currently no COVID restrictions in Northern Ireland however we must be aware that contracting COVID would be significant problem for visitors needing to return to their country of origin. There is now no distinction between vaccinated and non- vaccinated individuals when travelling to Northern Ireland. However we very much recommend that people are vaccinated before travelling Mask-wearing is optional in the UK but we will advise wearing masks in crowded areas and on public transport. We will advise mask-wearing during sessions when people are sitting close together for long periods. Given the number of attendess and capacity of the meeting venue social distancing should be possible. 4 5 ICAR 2 O 22 ICAR 2 O 22 Details of the ICC Belfast Conference Venue ICAR2022 events take place on four levels at the ICC.

The Multinational Arabidopsis Steering Committee (MASC) and the organisers of ICAR2022 are committed to ensuring that ICAR conferences are a welcoming and inclusive space for sharing of ideas, knowledge exchange and for developing collaborative opportunities for everyone who attends. To this end, ICAR2022 will provide a safe environment that promotes equal opportunity and treatment for all participants and that is free of harassment and discrimination. This code of conduct applies to all registered attendees, speakers, exhibitors, staff, contractors, volunteers, and guests; and it applies both within the ICAR2022 conference venue, within the online-platform and in associated events and locations where ICAR2022 conference delegates are present. Download full Code of Conduct from MASC website ICAR2022 Weed Stampede ICAR meetings organised by the North American Arabidopsis Steering Committee (NAASC) have a long tradition of hosting a ‘Weed Stampede 5K’ as part of the event social calendar. We will continue this tradition at ICAR2022 with the ‘ Run for the Throne: 5K Weed Stampede ’ run/walk that takes place at 7.30am on Wednesday June 22nd leaving from outside the Riverside Foyer of the ICC Belfast. This (mostly) non-competitive 5K will be led by Aoife McVeigh from VisitBelfast and takes in a lovely route along the river Lagan. A member of conference staff will be walking the route over an hour ‘sweeping’ so- as to ensure all participants safely finish the event. Participants take part at their own risk. In case of emergency call ‘999’ to access the UK Ambulance Service. A digital route map will be supplied to all participants. 8 9 ICAR 2 O 22 ICAR 2 O 22 ICAR2022 Meeting Schedule NOTE: All times are in BST (GMT+1).
