Habitat & Geographic Range

Cluster Fescue

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Range

Found in United States.

Epaulard

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador, Venezuela).

Cluster Fescue

Cluster fescue, known scientifically as Festuca paradoxa, is a perennial bunchgrass in the family Poaceae that holds the tragic distinction of being Extinct. Endemic to the central and eastern United States, this grass once inhabited moist, shaded woodland edges, floodplain forests, and riverbank communities where it formed discrete clumps characteristic of caespitose fescues. Festuca paradoxa was a slender, cool-season grass reaching approximately 60–120 centimeters in height, with flat or loosely rolled leaf blades and an open panicle inflorescence. It was associated with rich bottomland soils where periodic flooding maintained the open canopy conditions it required. The species declined catastrophically due to the widespread destruction of floodplain woodlands across its range through agricultural conversion, wetland drainage, and urban development over the nineteenth and twentieth centuries. Invasive species competition and altered hydrological regimes further compressed suitable habitat. The genus Festuca contains hundreds of species distributed globally in temperate and montane regions, but F. paradoxa occupied a narrow ecological niche that proved impossible to sustain amid large-scale landscape transformation. Its extinction represents a permanent loss from North American grassland diversity, and no living populations are known to persist anywhere in its former range.

Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
