ABSTRACT
Since the beginning of 2020, COVID-19 is raging around the world. Some of areas in Japan have cancelled spring burning of semi-natural grasslands to prevent the spread of COVID-19. Because records of the impact of the infection on grassland management are considered important, I have documented the information found on the internet about cancelled spring burning related to COVID-19. From late February to mid-May 2020, I searched for any combination of keywords including "Hiire", "Noyaki", "Yamayaki", "Yoshiyaki" (These four words mean "burning" in Japanese.), "corona", and "cancelled" using Google and social networking sites (e.g. Twitter and Facebook) to gather information about cancelled burning due to COVID-19. As a result, I found that burning was cancelled in 18 grasslands in 14 prefectures, and carried out with restrictions in four grasslands in four prefectures in Japan. These cancellation of spring burnings of semi-natural grassland by COVID-19 could affect biodiversity of grasslands and the safe burning of the following year and beyond.
