Cayman Invasive Plants and Native Alternatives


Native species

A Cayman Islands native (indigenous) species is one that occurs naturally in the Cayman Islands without direct or indirect human actions. Some plants and animals are native to only one or two of the three Cayman Islands.

Cayman Common Names

Different countries have different common names, sometimes more than one for the same plant, or one name may refer to several different plants, for example – Ironwood. Scientific names avoid the confusion of which plant is being referred to. If a plant did not have a use in Cayman, it often didn’t have a common name. However, some have a common names, because of the way they were encountered, eg Shake-Hand trees, with spines on their trunks – Xylosma bahamense and Zanthoxylum coriaceum.

Xylosma bahamense spines Nov23-06_075

Zanthoxylum coriaceum Feb23-02 AS

Cayman Islands common names are often unique, if the same plant occurs in Florida, it will almost always have a different common name. For example, Cherry – Myrcianthes fragrans, with bright red fruits and pretty pinkish bark, is called Twinberry, Nakedwood or Simpson’s Stopper in Florida and Wash Wood – Jacquinia keyensis, is called Joewood. Strawberry – Eugenia axillaris, is called White Stopper in Florida, and Red Rodwood or Black Cherry in Jamaica!

Invasive Species

An invasive species is an introduced species that becomes destructive to the environment or human interests. An invasive species is a non-native plant or animal, which adversely affects the habitat it invades, ecologically or economically. Great movement of goods between countries, has facilitated the transport of plants and animals, across geographical barriers (oceans and mountains), allowing them to colonize new areas of the world. A breeding population becomes established in the new location without further intervention by humans and threatens local biodiversity.

Shifting baselines:

  1. A tendency to overlook slow, steady deterioration of ecosystems because they are less obvious than large scale alterations.
  2. A species which have been present for a number of generations to be perceived as native or to be mistaken for native species.

The shifting baseline undermines environmental awareness and erodes a concept of cultural heritage, promoting a misplaced attachment and valuing of the exotic, the immediate and the commonplace, above the natural, the traditional and the rare.

For example:

Invasive Alien Species in the Cayman Islands

Almond, Indian Almond – Terminalia catappa

Almond, Indian Almond is a fast-growing tree with conspicuously whorled horizontal branches, that is tolerant of strong winds, salt spray, and moderately high salinity in the root zone. It grows in freely drained, well aerated, sandy soils.

Bark: often has Yellow-bellied Sapsucker drillings – a winter visitor woodpecker to Cayman.

terminalia catappa, leuco feb.15-17

Leaves: Alternate, large, spirally clustered at the ends of branches. Fall, winter and spring seem to occur within a week or so. The leaves turn bright scarlet, dark-red, dark purplish-red, or yellow and, in a few days, are shed all at once, especially after a sudden rain. They are quickly replaced with purplish new foliage, soon becoming green.

Flowers: arranged in several slender spikes, greenish-white, very small, no petals, but 10-12 conspicuous stamens. The perfect (fruit-producing) flowers are towards the base, while those towards the apex are staminate (male only).

Fruit: a smooth, waxy, slightly flattened bony oval drupe with thin, edible flesh, ripens from green to yellow. It is 4-7cm long, 2.5-3.8cm wide, ellipsoid, more pointed at the apex than at the base, slightly flattened, with a prominent keel around both sides and the tip, contributing to its ability to float long distances in the sea.

Seeds: edible, rich in oil and have an almond-like flavor.

Seedlings grow from the copious fallen fruits.

Native to tropical Asia

Terminalia catappa Aug.23-18 AS

Asian Colubrina, Asian Latherleaf – Colubrina asiatica

Asian Colubrina is a sprawling, scrambling, trailing shrub that grows rapidly in full sun. It is an aggressive colonizer, smothering surrounding vegetation, shutting out the light. It grows on all three islands.

Leaves: Alternate, shiny green with finely toothed, wavy margins.

Flowers: small, greenish with five petals

Fruit: capsule

It proliferated after Hurricane Ivan in 2004, as many trees had fallen.

Native to Eastern Africa, Southeast Asia, tropical Australia and the Pacific Islands

California Fan Palm (Washingtonia filifera)

California Fan Palm is a tall palm tree, lacking a strong root system that would support it in a hurricane. There are hairy filaments, especially on the younger fronds of the young palm trees, extending from the edge of the frond. Sharp spines on the frond stem make pruning hazardous. The fruits are eaten and dispersed by birds.

Native to the southwestern United States and northwestern Mexico.

Tall California Fan Palms and Casuarinas / Australian Pines are both shallow rooted and likely to topple in storms

Casuarina, Weeping Willow Australian Pine – Casuarina equisetifolia

 Casuarina, Weeping Willow, large, fast-growing, shaggy evergreen trees, have proliferated in Cayman in the last century. Highly salt-tolerant, they have become a well-loved tree, especially on beaches, but they are an invasive menace.  They grow tall, are shallow-rooted and topple easily in storms, exacerbating beach erosion. Their ‘needles’ form a dense carpet and exude a resin which prevents the growth of native plants, much more suited to the ecosystem, such as Sea Grape (Coccoloba uvifera), Coco-Plum  (Chrsyobalanus icaco) and Jennifer/Juniper (Suriana maritima).

Leaves: reduced to minute scales, encircling needlelike branchlets at regularly spaced nodes. The branchlets look like pine needles. If they fall on your car, they may damage the car’s air-conditioning system.

Flowers: unisexual, the plants are monoecious (separate male and female flowers are borne on the same plant).

Fruit: after fertilization the pistillate (female) flower-head becomes hard and cone-like.

Native to Australia.

Logwood – Haematoxylum campechianum

Logwood is a small, thorny tree with a deeply fluted trunk and wide spreading branches. It grows fast and aggressively colonizes in low-lying damp ground, that is not too salty. The wood is hard, heavy and slow to rot and is still used for fence posts.

Leaves: Alternate, compound, with no terminal leaflet.

Flowers: small, bright yellow and very fragrant in January, February and March. They attract bees.

Fruit: flat and wing-like pod.

Native to Central America, it is naturalized in the West Indies, where it was introduced early in the 18th. century as an export for its bluish-black dye from the red heartwood. It was a source of dye formerly used for textiles and which is still highly valued as a bacteriological and cytological stain.

Purple Allamanda (Cayman), Palay Rubbervine – Cryptostegia grandiflora

Purple Allamanda / Rubber Vine is a woody, trailing or climbing vine, a garden escape. The flowers resemble those of Purple Allamanda (Allamanda violacea), hence it’s Cayman common name.

Leaves: Opposite dark green, glossy with milky sap.

Flowers: showy, funnel-shaped, lilac-purple.

Fruit: thick, pointed woody follicle splits to discharge ‘milkweed’ parachutes, dispersed by wind or flooding.

Native to Africa (Madagascar). It was later grown in India to produce a poor quality rubber latex.

It is poisonous.

Scaevola, Beach Naupaka – Scaevola taccada = S. sericea

Scaevola taccada Feb28-14_i

Scaevola, Beach Naupaka is a large, bushy shrub, often forming dense hemispherical mounds. It is very salt-tolerant and is widely used in landscaping coastal properties. It crowds out native vegetation and has an extensive rooting system. It is difficult to control. The fleshy branches are easy to pull up by hand, but broken underground stem segments readily resprout if not completely removed.

Branchlets have white pith.

Leaves: closely Alternate, fleshy, often densely crowded.

Flowers: white half-flower with 5  petals, partially fused.

Fruit: a fleshy sub-spherical white drupe in clusters, produced in the first year or second year. The seeds are dispersed by birds and by water. Fruits may remain viable in salt water for up to a year, and can be spread along  the coast, canal banks and mangroves.

Native from East Africa to India, Southeast Asia, Australia, Pacific Islands

Wild Tamarind – Leucaena leucocephala

Wild Tamarind, a shrub or small tree, should not be confused with Tamarind (Tamarindus indica) a large tree, native to tropical Asia, with edible acidulous fruits that has become naturalized in Cayman. Wild Tamarind colonizes cleared land rapidly and is difficult to eradicate. It is characteristic of secondary growth thickets, old fields and roadsides.

Leaves: Alternate, bipinnately compound, 10-20 pairs of leaflets

Flowers: small globose pin-cushions of radiating stamens, yellowish or white.

Fruit: clusters of flat green, then brown, pods, with numerous shiny dark brown seeds.

Native to Mexico and Central America.

Wild Tamarind is a nitrogen-fixer and therefore a good soil builder. Livestock like it, but it contains the alkaloid mimosine, which causes toxicity in horses, cattle, pigs, and sheep. Horses are especially susceptible. It may result in the loss of long hair – manes and tails, and loss of condition. This happened in Cayman to horses and ponies in a pasture on South Church St. Goats are not affected.

Cayman Islands Native (Indigenous) Species Definition

A Cayman Islands native species is one that occurs naturally in the Cayman Islands without direct or indirect human actions.Some plants and animals are native to only one or two of the three Cayman Islands.

Some plants & animals have been introduced & become naturalized, they survive in the wild. If they are not native (indigenous), they will be noted as naturalized.

Cayman common names are almost always different from those used for the same plant when it occurs in other countries.

Fruit – could be a berry (many seeds), drupe (one central stony seed), capsule, pod etc. It does not necessarily mean an edible fruit for humans, but may be for birds

Grand Cayman’s birds suffered very badly as a result of Hurricane Ivan (Sept.11-12, 2004) & its aftermath, when there was little food or shelter. The preservation & re-planting of Cayman’s indigenous (& a few that have become naturalized & grow in the wild) trees & shrubs, in clusters, rather than singly, will create a network of mini-woodlands to aid the re-establishment of bird populations. Listed are different species that provide suitable roosts & nesting sites & a year-round supply of fruits for BIRDS.

Casearia staffordiae MT Jun22-01 ASCayman Casearia – Casearia staffordiae, Critically Endangered Grand Cayman endemic, first noticed on the Mastic Trail by Ann Stafford on June 22, 2001.

Casearia staffordiae fl, North Side Nov10-02 ASFlowers were found near Forest Glen, North Side on Nov. 10, 2002.

Cayman Casearia and Cayman Scolsanthus could not be botanically described until flowers and fruits were found. This took several years.

Casearia staffordiae fr Jan.9-05_909 ASFruits were found on this previously undescribed species on the Mastic Trail on Jan.9, 2005, over 2 years after flowers had been found, in a different location.

They were then determined by botanist Dr. George R. Proctor to be species new to science, Casearia staffordiae and Scolosanthus roulstonii. He named them after their discoverers P. Ann van B. Stafford and Frank E. Roulstone III, naturalists, in recognition of their efforts in conserving indigenous species.

Ann was looking for Rat Wood – Erythroxylum rotundifolium, on the Mastic Trail in June 2001. She thought she’d found it and photographed it, but it wasn’t Ratwood. She found tiny flowers on this rare plant that grows only in the Mastic region of Grand Cayman. In January 2005, Ann and friends eventually found little fruits. Dr. Proctor took a specimen to the United States National Herbarium at the Smithsonian Institution in Washington, D.C. Comparing it with close relatives of the genus Casearia, he determined that it was a previously undescribed species, a species new to science. He named it Casearia staffordiae. It is a very slow-growing Critically Endangered Grand Cayman endemic shrub.

KEW and OTEP – Cayman Islands

Kew, Royal Botanic Gardens and OTEP (UK Overseas Territories Environment Programme)CAYMAN ISLANDS

There are 415 species and varieties native to the Cayman Islands. Of these, 21 species of higher plants are known to be endemic with a further eight species representing endemic Caymanian varieties. Perhaps, the most important species are those that are endemic to a single island. Grand Cayman lays claim to the greatest number of endemic species: Hohenbergia caymanensis, Salvia caymanensis, Pisonia margaretae, Dendrophylax faucettii, Scolosanthus roulstonii, Casearia staffordiae, Agalinus kingsii and Aegiphyla caymanensis. Grand Cayman also has three endemic varieties: Pectis caymanensis var. robusta, Terminalia eriostachya var. margaretiae, and Myrmecophila thompsoniana var. thompsoniana. Cayman Brac has one endemic species, Verbesina caymanensis and two endemic varieties: Consolea millspaughii var. caymanensis and Epiphyllum phyllanthus var. plattsii. One endemic species is restricted to Little Cayman, Chamaesyce caymanensis. There are also three sister island endemic species (i.e. restricted to two of the Cayman Islands) and one endemic variety. In addition, twenty four species are considered near-endemic (i.e. native to the Caymans and one other island) and forty four are local regional (i.e. native the NW Caribbean region).
