The EAG continues its project: The Conservation of Ferns of Antigua and Barbuda. The project aims to research and conserve the native ferns of Antigua, Barbuda and Redonda, and over the last year, the project’s Principal Investigator, Kevel Lindsay, has conducted several weeks of fieldwork to study to and determine the status of the ferns of the country, highlight those of critical conservation concern and develop a conservation outlook for the species and their habitats, including their overall value to the country’s biodiversity heritage, while working to increase local awareness and appreciation for them.


Ferns in Antigua and Barbuda come in amazingly diverse forms - mangrove ferns which can grow to 4 metres high, tiny epiphytic ferns, a centimetre or so high, aquatic ferns, vine-like climbers and grass-like species. The leaf shapes come in an enormous variety of feathery arching fronds, tongue-shaped fronds, grass like fronds and even clover-shaped fronds.


We are very grateful to the Rufford Small Grants Foundation and the Mohammed Bin Zayed Species Conservation Fund who have generously provided funding for this project.

Why are ferns so important?


The ferns of Antigua, Barbuda and Redonda are one of the least studied and least understood groups of plants. Many are quite rare, and most are found in the volcanic southwest of the island, some restricted to the moist sheltered valleys of the this region. Some species are rarely seen, including Thelypteris patens—common on other more mountainous Lesser Antillean islands, but quite rare in Antigua and last seen perhaps over 40 years ago; or Thelypteris hispidula, a species that has been nicknamed the “pepper fern” because of the stinging sensation that results when the leaves are pressed on to the tongue. Antigua has two varieties: var. hispidula causes a mild to moderate burning sensation to the mouth, and var. inconstans cause extremely mild numbness. These species can only be observed in steep remote valleys with stable montane forests where there is lots of moisture such as in upper Christian Valley.

 

Tropical ferns are extraordinarily beautiful plants with their delicate arching leaves, or fronds as they are usually called - undoubtedly the most beautifully shaped leaves in the plant kingdom!

 

Also, ferns beautify the environment in a way that other plants cannot. This is because many ferns live in environments that other plants cannot tolerate - on shady tree branches ("epiphytes"), on rock faces (lithophytes), in wetlands and in mangrove environments. Tourists from Europe and America are especially awestruck as they normally only encounter these beautiful plants as indoor pot plants! Although most ferns prefer damp, shady conditions, some of our ferns, like the spectacular Goldback Fern on Redonda, grow in dry, sunny locations ("xerophytes") - this is particularly amazing to many tourists who have never encountered such ferns.

 

As well as their beauty, ferns are especially valuable plants for the following reason: Because most fern species can only survive in healthy moist, shady forests, many of which are under threat throughout the Caribbean and also in threatened mangrove and wetland areas, they are an important barometer of the ecological health of the environment.


Background to the Project


The project is a natural outcome of the Antigua and Barbuda Plant Conservation Project (ABPCP), which in 2009 produced one of the most significant works on the country’s native and naturalised plants: The Wild Plants of Antigua and Barbuda: An Illustrated Field Guide to the Native and Naturalised Vascular Plantsclick here for more information.


Progress to Date


The EAG has published two new reports on the country’s ferns and their habitats:


 - The Regional Red List of Pteridophytes of Antigua and Barbuda

 - Protecting the Native Pteridophytes of Antigua, Barbuda and Redonda: A Conservation Perspective


These are available as free downloads - click on the boxes in the left column on this page.


Several new species of ferns have been added to the country’s record, which up until 2007 stood at around 50 species. The list of ferns for the islands currently stands at over 80 species, and that number is growing. Fieldwork over the last four years, and especially over the last 12 months, have added some new interesting records, including the Netted Adder’s Tongue (Ophioglossum reticulatum), a species of primitive ferns with simple leaves reminiscent of a tongue, and spores on long stalks, and the Glossy Maidenhair (Adiantum pulverulentum), a beautiful and delicate species found only at Mount Obama. There are also several species found only in the West Indies that have now been added to our islands’ list.

 

Through this project, the team has also added new plant species to the country’s record, including new orchids and other plants, and has also photographed many rare plants, some now being seen for the first time by local experts.


Ongoing Work


So what’s coming up next for this project? The EAG is working on an atlas and guide to the country’s ferns. Hopefully, a first draft will be available by the end of 2012. Stay tuned for updates on this.


The organisation is also working tirelessly to secure additional funding to expand the effort to address the conservation of the islands’ rare plants and their habitats. This is a major challenge, and one with a long-term view, but the EAG is up to the task. We will keep our readers updated on our progress.

Conserving the Native Ferns of Antigua and Barbuda

Rufford MbZ Species Conservation Fund

The EAG would like to thank the Rufford Small Grants Foundation and the Mohammed Bin Zayed Conservation Fund for their generous financial support for this project.

With this document, it is our hope that we may encourage national support for the protection of native species and habitats, to stimulate science and research of the local flora and fauna, and to help increase the awareness about the importance and value of the islands’ native fern flora.

With this effort, the EAG hopes to focus attention

on the country’s pteridophyte flora, to encourage national support for the

protection of native species and habitats, to stimulate science and research into

the local biodiversity, and to help increase the awareness about the importance

and value of the islands’ native fern flora.
