Building Thick Swamp Forest
I would like to create a thick swamp forest from an open wetland area in zone 5.
Current property environment:
-Standing water 4" deep year around with 24" of muck
-Ful sun for the most part - there are a few trees here and there, but they are mostly dead
-In the spring, it may have as much as 1.5' of water for a couple weeks
-Not easily walk-able or usable - you sink
-Currently has a 24" tall clumping grass - not think enough to stabilize the ground (not sure the type, but bumble bees love the tops in late summer)
I would like to plant something that does the following.
1) Firm up the ground for walking a bit
2) Provide animal cover and maybe even food (deer)
3) Spread fast and compete with the existing grass
4) Grow 4+ feet high (higher and thicker the better)
5) Grow in muck with little oxygen at the roots
I would really like it to become a thick swamp forest type of space.
Any advise? --bamboo, Arundinaria gigantea, river cane, ???
