FrogWatch is a citizen science program that tracks frog populations throughout the United States. Participants will choose a monitoring site that is easily accessible and close to where they live or work to listen to frogs that are calling throughout the warmer months. There are four indoor trainings to help orient people with the frogs that are in Southern Maryland/DMV area and their calls. Content is the same, so chose one training that fits your schedule. You can either attend in person or through TEAMS; a video link will be provided in a reminder email a week before the training.
