As the Guardian headline says this is both “Fascinating and saddening“, because these new species are migrants due to climate change/global heating.
This data was generated in a city farm in Bath, and shows the value of long term monitoring of small spaces by citizen scientists where the sites are harbouring biodiversity at local scales. Added to a bigger picture of species observations collected on e.g. iNaturalist, shows how citizen science can engage with climate change challenges, and have an impact on research.
One of the most heavily mapped areas in Beverley by density of observations is St Mary’s Graveyard, mostly thanks to the effort of Hull Natural History Society and MWN. If you’re ever in St Mary’s Graveyard, or at the other sites we are monitoring, don’t forget to add your observations to iNaturalist, as they will help us continue to monitor change (both improved biodiversity, and sadly the effects of climate change too) over time.
