When nurseries are focused on cash crops this is the result. I’m sure that if we wanted these to be monoculture Doug fir forests we wouldn’t have a problem here.
This is where government subsidies should step in to make viable small nurseries focused on diverse endemic species no more than an arbitrary distance from the site of it.
But, climate change is moving faster than the distance range of each nursery so seed collectors should be pushing the range and ecotypes and sending back to further nurseries to introduce some insurance into the genetics.
We have a group using similar techniques for genetic diversity:

Partnering with Australia’s leading rainforest genetic scientist and Australia’s leading research ecologist, this project will use the latest DNA analysis techniques to guide the development of a plantation to produce seed to grow planting stock with optimal genetic diversity for use in plantings in the ecological restoration of critically endangered lowland subtropical rainforest.
