Delphinium caseyi, also known as Casey's larkspur, is a flowering plant within the family Ranunculaceae. [1]

Contents

Their population is estimated to be at around 100 individuals, which lead to this species receiving a critically endangered status. [1]

Description

Delphinium caseyi is a perennial herb, with an erect growth habit. It can reach heights up to 85 cm tall. [2] It possess a thick, woody rootstock. [1] Basal leaves emerge from the base of the stem and leaf stalks can be up to 20 cm long. [2] Between May and June plants will produce a long and slender stem that hosts a dozen or more flowers. The flowers possess long spurs and hairy petals, which form a dense inflorescence. The flowering period will last from June to July. [2] Like all species within the genus Delphinium, Delphinium caseyi is toxic. [2]

Distribution and habitat

Delphinium caseyi is endemic to Cyprus, where it is confined to only the Kyrenia mountain range where it has been recorded at two sites, one near St. Hilarion Castle, and the other on the Peak of Mount Selvili. [2]

Delphinium caseyi grows in fissures of limestone rock, cliff faces and mountain peaks. It will also grow in mountainous shrubland habitats. [1]

This species is found at altitudes between 800 – 950 metres above sea level. [1]

Threats

Delphinium caseyi suffers from a severely fragmented habitat and there is a continuing decline in habitat quality. [2] Habitat fragmentation causes patches of habitat to become isolated, which makes it harder for individuals to colonize different areas. This can lead to inbreeding and loss of genetic diversity. Due to having such a small population D. caseyi likely possesses little genetic diversity. Genetic diversity is important as it helps a plant species adapt to changing environments. Lowered genetic diversity puts populations at risk as they are less likely to be able to adapt to threats such as climate change or disease. [3] Populations with lowered genetic diversity are more vulnerable to extinction. [4]

The grazing of livestock by farmers also puts the small population of D. caseyi at risk. [1]

Gathering of D. caseyi for scientific purposes such as to study puts the plant at further risk. [1] Collecting by plant poachers also puts the species at risk. D. caseyi's violet flowers make the species attractive and desirable [5]

Delphinium is a genus of about 300 species of annual and perennial flowering plants in the family Ranunculaceae, native throughout the Northern Hemisphere and also on the high mountains of tropical Africa. The genus was erected by Carl Linnaeus.

<span class="mw-page-title-main">Habitat fragmentation</span> Discontinuities in an organisms environment causing population fragmentation.

Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment, and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species. More specifically, habitat fragmentation is a process by which large and contiguous habitats get divided into smaller, isolated patches of habitats.

<i>Delphinium bakeri</i> Species of flowering plant

Delphinium bakeri, or Baker's larkspur, is a species of perennial herb in the buttercup family, Ranunculaceae. It is endemic to California in the United States, where it is a federally listed endangered species. It is known in the wild from one remaining occurrence near Salmon Creek in Sonoma County, where only seven plants remained as of March 2006.

<span class="mw-page-title-main">Wildlife conservation</span> Practice of protecting wild plant and animal species and their habitats

Wildlife conservation refers to the practice of protecting wild species and their habitats in order to maintain healthy wildlife species or populations and to restore, protect or enhance natural ecosystems. Major threats to wildlife include habitat destruction, degradation, fragmentation, overexploitation, poaching, pollution, climate change, and the illegal wildlife trade. The IUCN estimates that 42,100 species of the ones assessed are at risk for extinction. Expanding to all existing species, a 2019 UN report on biodiversity put this estimate even higher at a million species. It is also being acknowledged that an increasing number of ecosystems on Earth containing endangered species are disappearing. To address these issues, there have been both national and international governmental efforts to preserve Earth's wildlife. Prominent conservation agreements include the 1973 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the 1992 Convention on Biological Diversity (CBD). There are also numerous nongovernmental organizations (NGO's) dedicated to conservation such as the Nature Conservancy, World Wildlife Fund, the Wild Animal Health Fund and Conservation International.

<i>Banara vanderbiltii</i> Species of flowering plant

Banara vanderbiltii is a rare species of plant in the willow family known by the common name Palo de Ramón. It is originates from Puerto Rico in the hills of Rio Lajas, and the east peak of "Tetas de Cayey" mountains in Salinas, where there are fewer than 20 known individuals left in the wild.

<i>Delphinium cardinale</i> Species of plant

Delphinium cardinale is a species of larkspur known by the common names scarlet larkspur and cardinal larkspur. This wildflower is native to California and Baja California, where it grows on coastal, inland, and desert chaparral slopes, such as the Colorado Desert, and the Peninsular and Transverse Ranges. The presence of diterpenoid alkaloids, probably including the highly toxic methyllycaconitine, in above-ground parts of D. cardinale means that they are likely to be toxic if ingested.
