Schoenus nigricans | |
Schoenus nigricans is a species of sedge known by the common names black bog-rush [2] [3] and black sedge. [4] It is native to Eurasia, parts of Africa, Australia, and southern North America, including Mexico and the southernmost United States. It grows in many types of wetlands and other moist and alkaline habitat, including marshes, springs, seeps, peat bogs, heath, and alkali flats. This perennial plant grows in low, tight clumps 20 to 70 centimeters tall, with threadlike leaves bearing wide, dark brown ligules. The inflorescence is a small, flattened cluster of dark spikelets. The fruit is an achene coated in a hard, white shell.

NVC community H5 is one of the heath communities in the British National Vegetation Classification system. It is one of three communities which are considered transitional between the lowland dry heaths and the wetter communities classified in the NVC as mires.
Vertigo geyeri is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusc or micromollusc in the family Vertiginidae, the whorl snails. The specific name geyeri is in honor of German zoologist David Geyer (1855–1932).
Rhynchospora alba, the white beak-sedge, is a plant in the sedge family, Cyperaceae. It is a tufted herbaceous perennial around 50 cm tall, with white inflorescences that flower in August. The fruit of the sedge is a small achene with a characteristic beak-like cap. It is dispersed by wind or falls by gravity, leading to individuals existing in tight clumps. The species favours wet, acidic and nutrient poor soils, thriving in Sphagnum-dominated bogs, but also peaty grasslands. As such it is often used as a positive indicator for bog and mire ecosystem health.

Schoenus is a predominately austral genus of sedges, commonly known as bogrushes, or veldrushes in South Africa. Species of this genus occur mainly in South Africa, Australia and Southeast Asia. Others are found in scattered locations worldwide, from Europe to Asia, North Africa and the Americas. Three species occur in the peatlands of southern South America, including S. antarcticus which is found in Tierra del Fuego, where it forms a component of hyperhumid Magellanic moorland.
