[The Observer 10 March 2015 by Jennifer Summer] TX: USA — The city of Roman Forest is taking steps to reduce the invasive plant species, Salvinia, that has pervaded Pine Pond. After receiving a permit from the Texas Parks and Wildlife Department, Roman Forest purchased 12 13-inch Triploid Grass Carp fish to introduce into the pond to control the floating ferns. “A Roman Forest resident noticed the plants growing on top of the water which would eventually take over the whole pond, depriving it of oxygen and kill everything,” Elizabeth Mullane with Roman Forest said. “We had a resident scrape and remove most of the Salvinia from Pine Pond but we wanted to make sure it was taken care off during the cold months when it doesn’t grow as fast.
