Cluster Bat

Myotis sodalis, the Indiana bat or cluster bat, is a medium-sized insectivorous bat in the family Vespertilionidae endemic to the eastern United States. It is one of the most endangered bats in North America, listed as Endangered under the U.S. Endangered Species Act and classified as Near Threatened by the IUCN. The species is named for its behavior of clustering in extremely dense hibernation groups—sometimes thousands of bats per square meter—in specific limestone caves and mines during winter. These few critical hibernacula make the species extremely vulnerable to disturbance and disease. Since 2007, Indiana bats have suffered severe mortality from white-nose syndrome, a fungal disease caused by Pseudogymnoascus destructans that disrupts hibernation and causes mass starvation. During summer, Indiana bats roost under loose bark of dead trees and forage for insects over forested landscapes and riparian areas. Foraging individuals consume moths, beetles, and flying insects. Conservation efforts include cave gate protection, white-nose syndrome research, and summer habitat management on public and private lands across the eastern US.

Coast Barnyard Grass

Coast barnyard grass (Echinochloa walteri) is a robust annual grass in the family Poaceae, native to wetlands and coastal marshes of eastern North America, from southern Canada south through the United States. It grows in tidal fresh marshes, brackish marshes, pond margins, wet roadsides, and floodplain habitats, where it can form dense stands exceeding 2 metres in height. The genus Echinochloa is widespread globally and includes several species of agricultural importance, both as crops and weeds. Coast barnyard grass is distinguished by its long, bristle-tipped spikelets and preference for wetland edges. It produces abundant seeds that are consumed by waterfowl including ducks, rails, and sparrows, making stands of this species ecologically valuable in coastal wetland systems. The species tolerates seasonal flooding, fluctuating salinity, and disturbed conditions. Its IUCN status is Least Concern, reflecting its broad distribution across eastern North America and its capacity to colonise disturbed wetland habitats rapidly. While not an invasive species outside its native range, it is sometimes managed in wetland restoration projects to prevent monoculture dominance.
