The Blind Small-eared Shrew (Cryptotis niausa) is a species in the genus Cryptotis. It is currently classified as Data Deficient on the IUCN Red List. Typically found in diverse terrestrial and aquatic ecosystems.

Common Oak Sedge

<em>Carex pensylvanica</em> is a low-growing perennial sedge in the family Cyperaceae, native to eastern North America, including Canada and the United States, with isolated records from Norway. It typically inhabits dry to mesic woodlands, grasslands, and forest edges, forming dense clonal colonies through rhizomatous spread. The species is well adapted to shaded environments and is often found beneath oak canopies, which gives it its common name. Its habitat associations span grasslands, wetlands, open forests, and disturbed or cultivated areas. The plant produces slender, grass-like leaves and small inconspicuous flower spikes characteristic of the genus Carex. It tolerates a range of soil conditions, from sandy to moderately fertile substrates. Conservation status has not been formally evaluated by the IUCN, and the species is considered broadly secure across its native range. Biological traits such as average lifespan, body measurements, and dietary preferences remain poorly documented in standardized databases for this plant species. It plays an ecological role as ground cover and erosion stabilizer in woodland understories, and is increasingly used in native plant landscaping and ecological restoration projects.
