The United States Botanic Garden, which calls the Florida yew one of the rarest trees in the world, says another reason the trees are endangered is because many are on private land, and endangered species laws do not protect endangered plants on private property.

Chestnut trees with blight cankers can be cured with mud packs applied to each canker, or protected with a biological control based on a virus that keeps the blight fungus from killing trees.
What kills horse chestnuts?
While many of the horse chestnut trees are being weakened by various pests/pathogens – leaf mining moth, Guignardia leaf blotch, wood rotting fungi and horse chestnut scale insect – only the rapidly-spreading bleeding canker, a bacterial disease caused by the Gram negative Pseudomonas syringae pv aesculi, can kill
What is wrong with the horse chestnut trees?
The current disease in horse-chestnuts is caused by a bacterium called Pseudomonas syringae pv aesculi. What damage does it do? To put it simply it clogs up the tree’s veins. The most obvious symptom is weeping wounds from the trunk of the tree and rust-coloured stains on the bark.
