#VegetationScience #FieldEcology #GreeleySymposium

At the University of Northern Colorado for the IAVS @iavs5.bsky.social excellent annual conference… and the acronym for our hosts on their double doors reads UNC UNC, or to botanical surveyors from New Zealand UNCunc… Uncinia (I know it’s now Carex) uncinata: bastard grass. Glorious.

🌿 The #IAVS2025 Pre-Symposium Excursion was amazing!

The days before the conference started participants explored an incredible range of ecosystems — from prairie to montane forests, subalpine meadows, and alpine tundra.

Day 1!! I am so sorry to miss it, but I hope everyone is having a great time!

Sounds very interesting! Please don't miss out 🌱🌿
