Purple Loosestrife
Detailed Description
Many species of birds rely on wetlands such as this baldcypress swamp, one of the ecosystems currently being studied by scientists at the USGS NWRC.
Purple loosestrife invades riparian areas throughout the north-central US. Researchers at the NWRC and in the Czech Republic work together to better understand the plants' growth and reproduction strategies in their native and introduced regions.
