Considering their specific relationship with bacteria, they need a warmer than usual environment to promote bacteria-growth. Since they rely on the bacteria to digest long-chain enzymes and complicated proteins drawn out of the soil by their roots, they probably need an environment rich in fauna and flora, with a source of raw undigested resources nearby. That coupled with the location of the last 2 examples and the presence of the carar bacterium gives you the answers!

They need a biodiversity-rich environment with a source of enriched nutrients, explaining their presence near the volcano in the Koosh-zone. The Carar bacterium is obviously a highly-competitice species, so it could easily and fatally disrupt the bacterial biome with the Sea-crown. Couple that with bad luck and the scarcity of shallow volcanoes and you have the answer to the Seacrown's endangered status :)
