2025_Autumn

Europe and Eurasia Tree (Phenology) Campaign

Trees are amazing. As autumn arrives, they prepare for their winter rest, turning their leaves into a stunning display of colors.

Observe your tree as its leaves change and fall, and share your findings with the GLOBE community. Discover the important role trees play in sustaining life on Earth and contribute to a global understanding of our environment.

What else can you do?

 

 

"The benefits are multiple for the students, such as observing nature and learning to be patient. They analyse the results, make a hypothesis and give the conclusion in the end, which is the basis for the scientific way of thinking."

Ankica Veseljić, OS Banija, Croatia
