Alpine Pika

The Alpine Pika (Ochotona alpina) is a species in the genus Ochotona. It is currently classified as Least Concern on the IUCN Red List. Typically found in diverse terrestrial and aquatic ecosystems.

Coast sandbur (Cenchrus spinifex) is an annual or short-lived perennial grass in the family Poaceae, native to warm coastal regions of the Americas but now widespread as a weed throughout tropical and subtropical regions worldwide, including Africa, Australia, and parts of Asia. It grows on coastal dunes, sandy beaches, roadsides, disturbed ground, and the margins of agricultural land. The genus Cenchrus is notable for producing sharp, bur-like seed clusters enclosed in rigid, spine-tipped involucres that readily attach to animal fur, clothing, and footwear for dispersal—a highly effective mechanism for long-distance spread. Coast sandbur is considered a nuisance weed in recreational and agricultural settings due to its painful burs. It is tolerant of salt, drought, and nutrient-poor substrates, making it a successful coloniser of disturbed coastal environments. The IUCN conservation status is Not Evaluated. While not threatened in any way, coast sandbur presents challenges in areas where it has naturalised, competing with native beach and dune vegetation.
