Swamp Land Farming / Permaculture

Hey! I've done some digging but still coming up short on resources on this topic, so...

Can you recommend some resources for farming or homesteading on swampland? I'm considering buying some coastal property which fits this criteria. Also, how can I prepare for long term sea level rise (salinity-tolerant food plants)?

Thanks!

One plant does very well next to the seashore: Sea Buckthorn (Sea Berry/Sea Grape) Hippophae rhamnoides

(also do a Wiki search on it)
