Start your Zoom meeting early. Opening your meeting 15 minutes early helps you settle in and go over anything last-minute with your co-facilitators.
Welcome people as they arrive. Make sure at least one facilitator doesn't have their head buried in the tech, so that everyone is properly welcomed as they join.
Have fun! Your attendees have joined you because they are like-minded nature-lovers, seeking connection and opportunities to take action. Building a positive vibe and good relationships is your top priority.
