Plantperson and Nick,
Would you be open to sell or barter seeds when available?
I am sure it would naturalize inside our fruit forest

SHV.
I get it and agree that fundraising could help if directed correctly.
It's a similar situation with orchids in Ecuador, poachers raid the wilderness for plant exhibitions and botanical gardens. One local where quite angry with what was goin on in Mindo when I where there. So having these exhibitions and raising the Wow factor of a plant also increases demand significantly which will definitely reduce the local population as poachers go through. IMO the only way to avoid this is to never boast about the plant or spread it around a lot to reduce financial incentive and rarity factor.
Conservation land will not stay conserved forever If populations keep growing.
And governments use national parks (lines on a map) as national debt collateral. It's finances and big donors have similar motives or special trust documents for long-term property holding. IMO we can't depend on others to save our natural heritage, we all have to interact with nature in order to feel why it's worth to not destroy it in our strive for resource maximization.
I agree that botanical gardens usually have great capacities to multiply plants but I just don't see them sharing it here in Australia, I know they prune and garden a lot so they could definitely have days where people could come and take cuttings or seeds without damage to the garden from their actual garden scraps. It's not setup for sharing or conservation more for collectomania, tourism and enjoyment IMO.
I have given rare plants to Cairns botanic garden in an attempt to increase the number of those tree's in Australia. And hopefully someone will get to eat the fruit and pocket the seed in the future

Galatians,
I agree with you that real people (ranchers) usually do a better and efficient job then gov when compared.
IMO the issue is not who own's the land, it's the hoarding of the property that is the issue. I am sure that many people in the city would like to have a weekend "datcha" or small plot where they cultivate edibles and also leave some natural tree's shurbs etc. This is crowdfunding with human energy which benefits humans and wild plants and can go on infinitum. My reason tells me that the government is opposed to this since it gives people a way to be less dependent on them. Gov and aristocratic land holdings creates false land scarcity.
And a lot of the time up here, invasive species comes in after a cattle rancher have "improved" the lot by select cutting of tree's because cows don't eat tree's. The most invasive species we humans spread are grasses (guine, gamba, brachia) and that is from the cattle industry to begin with.
Those are invasive species and every cattle farmer "should" have to get rid of them, well why should a friend of mine have to remove a weed declared by the cattle industry (Parthenium) when they cultivate weeds declared by horticulturalists (gamba, guine, branchia). My friend don't have an issue with Parthenium so no financial loss for him. But he have to work a lot to keep the invasive grass down!
Why aren't government agencies knocking on the ranchers door to ask him to eradicate the invasive grass like they do with my friend??
And the biodiversity is very low in pastures, natural savannas of Africa have the highest mammal biomass of any ecosystem, but necessarily not high plant diversity, and no way near that of a forest. What happened to the cedars or Iran??
I prioritize plant diversity over mammal biomass.
And if you grew high energy crops for humans on the ranch you could increase the "conservation" area 10 fold since your not loosing energy converting grass or grain to flesh.
In the end I am happy to see a Tian in some ones basement

Humans are amazing!
