How do those trees get establised?
How do they not die from water logging?

Certain plants certainly can survive. Notably, two problem weeds in the everglades are Melaleuca and Casuarina. Both imported to the area from Australia.

Well I don’t know but I can post the relevant wikipedia paragraphs about the germination of swamp cypress if that helps.

Seed production and disseminationEdit

Some seeds are produced every year, and good seed crops occur at three- to five-year intervals. At maturity, the cone scales with their resin-coated seeds adhering to them, or sometimes entire cones, drop to the water or ground. This drop of mature seeds is often hastened by squirrels, which eat bald cypress seeds, but usually drop several scales with undamaged seeds still attached to each cone they pick. Floodwaters spread the scales or cones along streams and are the most important means of seed dissemination.

Seedling developmentEdit

Germination is epigeal. Under swamp conditions, germination generally takes place on a sphagnum moss or a wet-muck seedbed. Seeds will not germinate under water, but some will remain viable for 30 months under water. By contrast, seeds usually fail to germinate on better drained soils because of the lack of surface water. Thus, a soil saturated but not flooded for a period of one to three months after seedfall is required for germination.

After germination, seedlings must grow fast enough to keep at least part of their crowns above floodwaters for most of the growing season. Bald cypress seedlings can endure partial shading, but require overhead light for good growth. Seedlings in swamps often reach heights of 20 to 75 cm (8 to 29.5 in) their first year. Growth is checked when a seedling is completely submerged by flooding, and prolonged submergence kills the seedling.

In nurseries, Taxodium seeds show an apparent internal dormancy that can be overcome by various treatments, usually including cold stratification or submerging in water for 60 days. Nursery beds are sown in spring with pretreated seeds or in fall with untreated seeds. Seedlings usually reach 75 to 100 cm (29.5 to 39.5 in) in height during their first (and usually only) year in the nursery. Average size of 1-0 nursery-grown seedlings in a seed source test including 72 families was 81.4 cm (32.0 in) tall and 1.1 cm (0.43 in) in diameter.

Control of competing vegetation may be necessary for a year or more for bald cypress planted outside of swamps. Five years after planting on a harrowed and bedded, poorly drained site in Florida, survival was high, but heights had increased only 30 cm (12 in), probably because of heavy herbaceous competition. Seedlings grown in a crawfish pond in Louisiana, where weed control and soil moisture were excellent through June, averaged 2.9 m (9.5 ft) and 3.5 cm (1.4 in) diameter at breast heigh after five years. However, a replicate of the same sources planted in an old soybean field, where weed control and soil moisture were poor, resulted in the same diameter, but a smaller average seedling height of 2.1 m (6.9 ft). When planted in a residential yard and weeded and watered, they averaged 3.7 m (12 ft) tall three years later.

So it can be a bit floating island stuff.

Shy People is a 1987 American drama about two branches of a family that reunite, with tragic results. It stars Barbara Hershey, Jill Clayburgh, and Martha Plimpton. It was directed by Andrei Konchalovsky, written by Konchalovsky, Marjorie David and Gérard Brach, and features music by the German electronic music group Tangerine Dream.

Hershey won the Best Actress award at the 1987 Cannes Film Festival for her performance. It was one of the last film roles for actor Merritt Butrick, who died from AIDS in 1989. It was filmed by the bayous of South Louisiana.

Plot summary
Diana Sullivan is a successful Manhattan writer and photojournalist, seemingly oblivious to the serious cocaine addiction that her wild child daughter, Grace, has developed. A commission by Cosmopolitan magazine to write an article about a lost branch of Diana’s family leads them deep into the bayous of Louisiana, where they encounter Diana’s distant cousin, Ruth. Married at 12 to an abusive man whose current whereabouts are an increasingly troubling cipher, Ruth rules over her three adult sons, all less than perfectly cogent, with equal parts protectiveness and ferocity, while a fourth, disowned son adds to the volatility of the situation. As the fascinated Diana and wary Ruth circle one another, Grace, bored and in grip of her addiction, toys with her naive cousins with devastating consequences.

Well. that was heavy.

Melaleuca is definitely happy to have it’s feet wet. Casuarina too, but not so much.

I suspect that the main problem with plants getting their roots too wet is root rot? Is that right?

If so, then any tree resistant to root root would be OK growing in water, because they can get their air through their stomata.
