Scientists See More Vegetation In The Himalayas - But It Is Not Good News, Because That Extra “Green” Can Disrupt Water, Snow, And High-Mountain Biodiversity | Plants Growing Higher Across Himalaya As Climate Warms

“For years, the biggest climate warning from the Himalaya was easy to picture because glaciers were shrinking on the roof of Asia. Now, researchers are pointing to a quieter signal, one that can look almost harmless from a distance. The mountains are getting greener.
New research [link above] shows alpine vegetation moving higher across six Himalayan regions from 1999 to 2022, pushed in part by warming and reduced snow depth. That might sound like nature recovering, but in this fragile landscape, more plant cover at extreme heights may change how snow is stored, how water runs downhill, and how rivers behave for communities far below…”

First locally grown berry, so I'll start an early summer Toronto #phenology thread:

The all-day-sun bed had a couple of ripe strawberries on Saturday. They were pretty tasty!

Yesterday I saw my first daffodil in flower in ĹŚtautahi-Christchurch city, NZ. Others have been noticing them about the city too.

This particular patch is on one of my regular biodiversity run routes so I've got reasonable records of when it has started to flower. It does seem early, although doesn't beat last year's record.

First flowering of daffodils at the Church on the corner of Macmillan Ave and Dyers Pass Road:
2020: 19 June
2021: 24 July (noted as still in bud on 25 June)
2022: 1 July
2023: 10 June
2024: 4 July
2025: 25 May
2026: 5 June

It would be a clear trend if it wasn't for whatever happened in 2024. I saw no daffodils anywhere in flower in the city before July in 2024.

Green-up in the Fairbanks area was abrupt this week, as birch & aspen leaves popped out of their buds. Chena Ridge green-up on May 14 was later than normal but a few days earlier than 2022 or 2023. Since the 1970s there's no significant trend in the timing of green-up. #akwx #Spring2026 #Phenology

Congratulations to the Swiss Phenology Observation Network on its 75th anniversary – a tribute to over seven decades of dedication by 700+ citizen scientists across 160 sites! Starting in 1951, the network has tracked the seasonal cycles of 26 plant species. SwissPhenoCam and AI technologies are shaping the future of phenology, complementing traditional observations with satellite validation and pollen data insights. Here's to continued growth and innovation!

Did you know that there is a brand new R-Project Package for the Pan-European-Phenology Dataset?
Created by Matthias & Barbara Temple and very well documented for an easy start.
eg.: https://cran.r-project.org/web/packages/pep725/vignettes/getting-started.html
