Despite the Covid-19 situation, our institute relaxed the rules a bit, so we were free to start the field wok in Czech with some delays. Specifically, Marketa did her first spring treatments and Honza K set his temperate exclosure experiment. Amelia, Kore, Karthik, David and Legi helped them in the field. In the mean time, Katka spends all her time by writing grants and attempts to teach online. So she only supported the workers with coffee and cake in the field.
