Hello<br />We are living in the Czech Repiblic in the town Česká Třebová<br />We are a group of students interested in biology <img alt="emoticon" src="https://www.globe.gov/o/gov-globe-main-theme/images/emoticons/happy.gif" ><br /><br />This birch is growing before my house<br /><br />I observed birch in autumn (falling 4 leaves) and in spring (budding 4 buds and lenght 4 leaves). We used in autumn GLOBE Plant Color Guide and Green down protocol. In spring, we used Green up protocol. Also, we worked with Growapp.
