Our friends the seed dispersers
Botany One has been running an entertaining little series from Nigel Chaffey on how plants get about, as seeds and as the gametes that produce seeds. In the third and final part, we get to plants that could reasonably be considered of interest here, to whit cacao and useful forest trees. It turns out that chimpanzees in West Africa are not above nicking a few pods from cacao trees and spreading the seeds an average of 407 m from the plantations. I like the ideas that this illuminates the thorny question of who “owns” a crop.
Sticking with West African trees, it seems that gorilla and chimpanzee dung offers “a cost effective and non-invasive way to restore native forested habitats”. Of course, if the gorillas and chimpanzees are themselves threatened and don’t travel widely, that’s not going to help forests further afield. Chaffey suggests collecting their dung and distributing these auto-fertilising, self-selecting seed packages directly over the area to be reforested.
I wonder what the forest genetic resources people would make of that?

Another Committee on World Food Security report
I knew I’d forget one:
- HLPE. 2017. Sustainable forestry for food security and nutrition. A report by the High Level Panel of Experts on Food Security and Nutrition of the Committee on World Food Security, Rome.
The webcast is live now.
Also, since I’m at it, here’s a useful blog post on the other CFS report, the one on “Nutrition and Food Systems,” from one of the authors, summarizing eight ways why the report is different. This is what resonated with me most:
Third, it is, subversively, a bit radical. Statements such as “The risks of making well intentioned but inappropriate policy choices are much smaller than the risks of using a lack of evidence as an argument for inaction” are fairly heretical for many nutrition investors guided by Lancet 2008 and 2013. For the more market based interventions within the food system the hard evidence is usually not present and one has to trust educated best guesses and calculated risks as a guide to action.
Sometimes, you just have to do it.
