Cool. With all the seeds you have, I’d plant a bunch of them, lots and lots of seeds, in a good sized flat. Let them grow and weed them out for a massive forest. Letting nature help your tree selection process along the way. Let the strong trees fight for dominance. Probably ending up with a forest of 57+ trees or more. Roots all nicely together in a flatter planting. Would be a fun project over time seeing as how you have plenty excess seeds a a good growing environment.
