🌿 Lunch break with a view — and a mission

What's the status of urban biodiversity on our very own roof ? This Tuesday the Citizen Science Lab is hosting a lunchtime Expeditie Stadsnatuur on The Roof of PLNT. Together we'll explore what insects, spiders, and other creepy crawlies are living amongst our nature-friendly planting — in the greenhouse, on the green roof, and in the garden — and log every find with the free Obsidentify app.
No expertise needed. Just bring your lunch, your curiosity, and your phone. 🐌 🐜 🌱 🌼 🐝

This lunch-time expedition is part of Expeditie Stadsnatuur 2026, the region-wide citizen science mission to find 2,600 different species across Leiden, Leiderdorp, Oegstgeest and Katwijk. Every observation counts, including the ones right above our very own heads.

📍 The Roof, PLNT, Langegracht 70, Leiden🕧 Tuesday 2 June, 12:30–13:30🆓 Free for all PLNT building residents and visitors
See you upstairs! 👆
