Captive breeding of endangered aquatic plants

Texas wild rice (Zizania texana) is an endangerd aquatic perennial
found only in a short stretch of the San Marcos River in central
Texas. It is related to the wild rice grown for human food.
The plant is endangered because of the increasing water demands on the
Edwards Aquifer, which during severe droughts threatens to dry up the
springs feeding the river. It almost happened last year.
Southwest Texas State University, in San Marcos, is working on a
captive breeding program where they are trying to 1) increase the
range of the plant, and 2) provide a reserve stock, which can be
reintroduced into the wild if the springs dry up.
