- EcoregionsTreeFinder—A Global Dataset Documenting the Abundance of Observations of > 45,000 Tree Species in 828 Terrestrial Ecoregions. The right native tree for your ecoregion of choice. Which, given lots of the stuff below, is good to know. Oh, and BTW, there’s also the Agroforestry Species Switchboard.
- Modelling the distribution of plant-associated microbes with species distribution models. Would be cool to mash up with the above one day.
- The promise of digital herbarium specimens in large-scale phenology research. Something else you can use herbarium specimens for, if you’re careful.
- A global indicator of species recovery. The Green Status Index of Species Recovery, no less. Herbaria surely involved again.
- Valorization of feral pigs in the tropics, from the genetic characterization to the re- domestication. Wish there was a Green Status Index of Breed Recovery.
- Global staple food trade exacerbates biodiversity loss: a network perspective. Soybeans are messing with the Green Status Index of Species Recovery of lots of species, I suspect.
- Prospects for cereal self-sufficiency in sub-Saharan Africa. Prospects for self-sufficiency are not bad, but will require yield increases if the Green Status Index of Species Recovery is not going to take a hit.
- Protecting crops with plant diversity: Agroecological promises, socioeconomic lock-in, and political levers. Agroforestry and diverse landscapes are best for pest control, but cultivar mixtures are worth a try too. Wonder what they will do for cereal self-sufficiency in Africa. I lot, I bet, if given a chance.
- The dynamics of crop diversity and seed use in the context of recurrent climate shocks and poverty: Seasonal panel data evidence from rural Uganda. Farmers use crop diversity to cope with climate change, and wealthy farmers do it better. Pest control too, maybe?
- Understanding Farmer Preferences to Guide Crop Improvement: The Case of Grasspea in Ethiopia. Breeders should provide jam today and jam tomorrow.

Modified ecosystems and the conservation of crop diversity
A new global assessment of the state of terrestrial ecosystems has just been published, focusing on the extent of human modification due to “industrial pressures based on agriculture, forestry, transportation, mining, energy production, electrical infrastructure, dams, pollution and human accessibility.” 1
As is my wont, I tried to find a form of the data that I could shoehorn into Google Earth, but I failed. Fortunately GIS guru Kai Sonder of CIMMYT was able to snip out a kml file of overall human transformation as of 2020 covering Kenya — don’t ask me how. But thanks, Kai. I put on top of it genebank accessions from Kenya classified as wild or weedy in Genesys.
I don’t know quite what to make of this. The wild populations seem to have been mainly collected in areas that in 2020 were very highly affected by human activity. But is that good or bad?
It could be good — in a sense — if the high degree of human transformation means that the original populations are not there any more. 2 Phew, good thing they were collected! On the other hand, it could be bad if the concentration on easily accessible and modified areas means that the genetic diversity currently being conserved is not representative of what’s out there.
What do you think?
But of course what I really want is a version of this which focuses on agricultural areas and is updated in real time. Yes, a perennial favourite here: a real early warning system for erosion of crop diversity.

We knead oil
Jeremy’s latest newsletter has agrobiodiversity-adjacent snippets on the re-making of an ancient bread in Turkey and on the “oenification of olive oil.” Plus a thing on oysters which is maybe not so adjacent but is also fun and sports a title that is worth the price of admission on its own. Read it.
Brush up your seedcraft
I recently came across a few interesting resources that I’d like to share.
Bangor University has a publication out that might be useful to people doing research — or perhaps even implementing projects — having to do with in situ conservation: Conservation social science: A handbook for conducting research on rule breaking in conservation. 3
Understanding who follows rules and why, is pivotal for shaping and informing the design of conservation policy and strategies on the ground. If based on erroneous assumptions, sustainable solutions are unlikely to be realised. Conservation scientists need skills and methods that help them understand the prevalence and drivers of illegal activities.
I never really thought about it, but yeah, I guess they do. In any case, always a good idea for biology-focused conservationists to brush up on social science methods.
I’m not sure if the Center for Plant Conservation’s Applied Plant Conservation Course deals with rule-breaking explicitly, but Module V: Common Reasons for Reintroduction/Mitigation Failure might well cover it to some extent.
And finally, Kew has a cryopreservation course in the works for November 2025. And a more general seed conservation techniques course for October. No illegal activities are envisaged.
