I still think the NYC tree planting events were good for the community. People got together and dug around in the soils of their local parks and medians. We noticed the little wild places tucked between the buildings and met other people who cared. I think a better event could feature:
* identifying insects and wildlife
* better guides for the local groups
* planting native PLANTS not just trees
* weeding species that don't fit
* housing for bees and ants
