Dear colleagues, This note is just to share with you an update on the IUFRO conference, ““Biological invasions in forests: Trade, ecology and management”, 14-18 September, 2020, Prague, Czech Republic. We are closely monitoring the COVID-19 pandemic and, in particular monitoring anticipated impacts on international travel. At this point, we still expect that travel to Prague will be permitted and safe by mid-September. However, we acknowledge considerable uncertainty and are prepared to postpone the conference if necessary. We plan to re-evaluate the situation in mid-May. Information about the conference is available at https://iufro.v2.czu.cz/en/ We are extending the deadline for early registration to 1 July and the date for final registration to 15 August. We will continue to review the situation and provide updated information at this web site. Please let me know if you have any questions. -Sandy Andrew Liebhold http://sandyliebhold.com Northern Research Station 304-285-1512 USDA Forest Service 304-285-1505 FAX 180 Canfield St. 724-317-8668 mobile Morgantown, WV 26505 USA
