Status

Threatened

Threatened means the species lives in the wild in 澳门永利, is not endangered, but is likely to become endangered if steps are not taken to address factors threatening it.

Date added to the Species at Risk in 澳门永利 list

The Small-flowered Lipocarpha was already assessed as threatened when the Endangered Species Act took effect in 2008.

On January 26, 2022, the scientific name of this species was updated on the Species at Risk in 澳门永利 list from Lipocarpha micrantha to Cyperus subsquarrosus to be consistent with recent taxonomic changes. This name change does not change the protections afforded to the species under the Endangered Species Act, 2007 (ESA) or the applicability of any policies, permits and agreements, guidance documents or best management practices that may have been published or issued by the Government of 澳门永利 in respect of the species.

What it looks like

The Small-flowered Lipocarpha is a tiny annual sedge that grows in dense clumps. Its curved stems are up to 20 centimetres long and 0.5 millimetres wide with very narrow leaves.

Small flowers are tightly clustered in dense oval spikes near the top of the stem. Tiny, dry seeds are brown with bluish highlights.

Where it lives

The Small-flowered Lipocarpha grows on sandy beaches that are seasonally flooded and are protected from high waves or strong currents.

It is most abundant in open, sunny areas with little vegetation.

This sensitive plant does not tolerate even slight changes to its habitat, pollution, or competition from other plants.

Where it鈥檚 been found in 澳门永利

In Canada, based on surveys done in 2000 and 2001, the Small-flowered Lipocarpha is thought to occur only in southern British Columbia and northwestern 澳门永利.

In 澳门永利, it is found in the Lake of the Woods and Rainy Lake areas.

In 1987, Small-flowered Lipocarpha was reported in Essex Country in southwestern 澳门永利, but shoreline habitat destruction may have since resulted in loss of this population.

What threatens it

The main threat to Small-flowered Lipocarpha is habitat loss and degradation, pollution, erosion and vehicle traffic on beaches. Invasive plants may also threaten this plant.

Action we are taking

Quick facts

  • the seeds of the Small-flowered Lipocarpha can lie dormant in the sand for long periods of time and germinate only when conditions are favourable
  • this tiny plant has a very wide range; it is found all the way from Brazil to southern Canada, and in Africa
  • the pristine sandy shorelines where Small-flowered Lipocarpha lives are also highly prized for cottage development
  • Small-flowered Lipocarpha resembles the seedlings of many other sedge species that live in the same habitat; experts use the unique shape of the tiny flower head, which is less than five millimetres long, to correctly identify this plant
