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.

Cole's Wattle

<em>Acacia colei</em>, commonly known as Cole's Wattle, is a tree or shrub in the family Fabaceae, subfamily Mimosoideae. The species is assessed as Least Concern on the IUCN Red List, indicating that it is not currently at elevated risk of extinction. It is documented in Kenya and Tanzania, where it is associated with tropical and subtropical grasslands and savannas within the Afrotropic realm. Like many acacias, <em>Acacia colei</em> is likely adapted to seasonally dry conditions, which are characteristic of the East African savanna ecosystems it inhabits. Members of the genus <em>Acacia</em> often play important ecological roles, providing shade, food, and habitat for a range of animals, and some fix atmospheric nitrogen through symbiotic associations with soil bacteria. Diet, population estimates, and biological measurements including length, weight, and lifespan are not specified in available data for this species. Biological traits of this species remain poorly documented in the scientific literature. Its Least Concern status reflects a relatively stable population in East African savanna landscapes.
