<img src="https://www.globe.gov/documents/d/european-phenology-campaign/kampanja_2025-_green-down-png?imagePreview=1" height="344" /><br />In this campaign we monitored fig, oak and birch trees. We have completed the phenological monitoring of fig and oak. However, we are still monitoring the birch, which still has most of its leaves on its branches. We have published the graphs and photos in the form of a video on the shared Padlet. We are glad to have participated in this phenological campaign. Petrinja High School GLOBE team.

<span style="font-size: 12px;"><span style="font-family: &quot;Aptos&quot;, sans-serif">For the third consecutive year, we observed and measured the hazel tree at the Skoke (latitude 46.485905, longitude 15.696812, elevation 263m). The last hazel leaf fell on November 1. This year, the leaves fell 14 days earlier than in 2024 and 2023. The leaves did not turn brown at all this year; instead, they fell earlier due to strong winds. In 2025, the average temperature during the observation period was 16.1 °C, and 247 mm of precipitation was recorded. The temperature was 1.5 °C higher than in 2024. Precipitation was the same as the previous year. The higher temperature, along with stronger winds, was the reason for the faster leaf fall.</span></span><br /><span style="font-size: 12px;"><span style="font-family: &quot;Aptos&quot;, sans-serif"> </span></span><br /><span style="font-size: 12px;"><span style="font-family: &quot;Aptos&quot;, sans-serif">Best wishes,</span></span><br /><span style="font-size: 12px;"><span style="font-family: &quot;Aptos&quot;, sans-serif">Simon Gračner with students</span></span>
