Around 800 trees in the ground for today's Trees for Canterbury planting day! A big group of students from UC there helping reclaim another part of Ōtautahi for nature.

700 new native trees in the ground from today's Trees for Canterbury planting at Orton Bradley Park. Another small patch of Aotearoa returning to what it was.

A patch of young New Zealand native trees on a grassy hillside.

Fantastic presentation on Timescape by @ryanridden.bsky.social yesterday at the South Island Stardate. Exciting times in cosmology! He also gave an awesome presentation on Cosmic Cataclysms and how we can get involved in it through zooniverse. Wow! Some great research going on at UC!
