Canadian Botanical Association Association Botanique du Canada 1 2 WELCOME WORD The CBA is very pleased to be able to host a virtual version of its annual meeting this year. The organizing committee was of course very disappointed to have to cancel the in person event, having worked hard to offer an interesting scientific program, field visits and socio-cultural activities. We have rolled up our sleeves and used our creativity to prepare a virtual version of the conferences for you. We are particularly pleased with the enthusiasm of CBA members and the broader botanical community for this online version of the meeting. We were thus able to integrate presentations that we could not have had in person and we will have numerous participants from around the world with us. The 2020 CBA annual meeting is a landmark event in its mission to disseminate and promote knowledge and understanding related to botany, and along with the launch of its new website represents the movement of the association into a new digital era. We are hoping to welcome all of you in person at the 2022 meeting in our beautiful region of Abitibi- Témiscamingue! Nicole Fenton CBA President-Elect MOT DE BIENVENUE L’ABC est très heureuse de pouvoir tenir une version virtuelle de sa rencontre annuelle cette année. Le comité organisateur a bien entendu été très déçu de devoir annuler les événements en présentiels, ayant travaillé fort pour une programmation intéressante d’ateliers, de visite sur le terrain et d’activités socio-culturelles. Cependant, nous avons retroussé nos manches et avons usé d’ingéniosité pour vous préparer une version virtuelles des conférences et des sessions d’affiches. Nous sommes particulièrement contents de l’enthousiasme des membres de l’ABC et de la communauté de la recherche et de la pratique en lien avec la botanique face à cette version en ligne de la réunion. Nous avons ainsi pu intégrer des présentations que nous n’aurions pas pu avoir en personne et nous aurons des participants nombreux d’un peu partout dans le monde avec nous. La rencontre annuelle de l’ABC est un événement phare de sa mission qui est de diffuser et promouvoir le savoir et la connaissance en lien avec la botanique, et, avec la mise en ligne de son nouveau site Web, représente le désir de l’association d’entrer dans une nouvelle ère numérique. Nous espérons vous accueillir en personne à la rencontre de l’ABC en 2022 dans notre belle région de l'Abitibi- Témiscamingue!
