Seeing the new Tree Seed and Seedling Field Guide Series from the Landscape Alliance reminded me that I’d also meant to write about the International Principles and Standards for Native Seeds in Ecological Restoration. That’s been sitting on my to-do list for a while now. It is not one of those standards documents that tells you what everyone ought to do and leaves the messy details to somebody else. It really gets into the…well, I was going to say weeds but that would be all wrong. Let’s just say it’s pretty comprehensive: where the seeds should come from, how much to collect, how to maintain genetic diversity, how to process and store them, how to test viability and germination, and what information should accompany the seed lot to the person who eventually plants it. There is even a pro-forma label. In other words, lots of advice about how not to screw up the supply chain for seeds of native plants to be used in habitat restoration and the like.
The new field guides sit very nicely alongside that. They take the same concern with quality and turn it into practical guidance for people producing and using tree seeds and seedlings in Kenya and Rwanda. The scales and specifics are different, but the underlying problem is much the same: restoration depends on getting seeds from a wild population to a restoration site without losing the information, quality or diversity on which success depend. The standards provide a framework for doing that; the field guides help people put it into practice specifically for trees in East Africa.
It’s all a welcome corrective to the tendency to think that restoration begins when you put a seed or seedling in the ground. Quite a lot has to go right before you get to that bit. One question, though. Are all these various principles, standards, guides and recommendations integrated into the digital workflow for forest restoration that I blogged about a couple of weeks back?
