Seed Transfer Zones for Brosimum alicastrum in Central America

From a blog post by Alex Monro

As part of a recent grant from the UK Government’s Darwin Initiative (#18-010)  to provide tools to support sustainable reforestation with Brosimum alicastrum, a common tree in Central America, we have identified safe zones for seed and seedling transplantation. The aim is to protect the genetic diversity  of the species and the genetic distinctiveness of the regions whilst at the same time allowing it to be used in reforestation and restoration. To do so we undertook a genetic survey of the species across it’s range but with special emphasis on Central America where the species is most common and where demand for its use in reforestation is greatest.

Tonya Lander analysed the genetic data and using statistical techniques identified areas that were genetically distinct from each other. These are marked by thick black lines on the map above. We recommend that seeds and seedlings are not be moved from one area or zone to the next. If they are moved from one zone to the next, then once they reach maturity and begin to release pollen and produce fruits, this will erode the genetic distinctiveness of this area. Fortunately given the size of the zones this should not greatly impact ongoing reforestation in Central America.

The zones identified comprise:
1) Mexico, Guatemala, Belize, El Salvador, Honduras & Nicaragua,
2) Costa Rica, Panama & Colombia,
3) the Greater Antilles, and
4) South America excluding Colombia.

Two exciting seminars on Maya Nut tree at Kew

On the 24th and 25th of April Erika Vohman (CEO of the Maya Nut Institute) and Mike Rowley a grad student at the University of Bournemouth gave two great talks at the Royal Botanic Gardens Kew and its subsidiary, the Millennium Seed Bank at Wakehurst in Sussex. Erika spoke about our Darwin Initiative project with the tropical tree Brosimum alicastrum or Maya Nut which finished last month within the context of focusing sustainable development projects in Central America on women and markets.

Mike Rowley’s talk was on a completely different aspect of Brosimum alicastrum, the production of calcium oxalate crystals in its cells and the eventual conversion of these to mineral form by bacteria, as calcium carbonate, after the tree roots die. This is a very exciting phenomenon as it provides a mechanism whereby carbon dioxide from the atmosphere is converted to calcium oxalate in the plant and then calcium carbonate in the soil. Basically whereby carbon dioxide is sequestered in a very stable form as limestone that will remain stored in the soil for thousands of years.
