Lichen Emblem for PEI

Vote for Lichen Emblem for PEI

The four nominees first, then scroll down to vote in the online ballot below.

Lichens are neither plant nor fungus. In lichens we have a case of two life-forms, fungus and algae, living together with mutual benefits. The algal partner can convert sunlight to provide energy. Fungi are able give algae protection and provide water and minerals. Some lichens have a bacterial partner – its complicated. In Prince Edward Island, 328 lichen species have been recorded to date. Four nominees have been proposed. Your vote matters, as Nature PEI will be recommending the winner to the Government of PEI for consideration as an official provincial emblem.

The nominees are . . .

Bushy Beard Lichen (Usnea strigosa)

Bushy Beard Lichen (Usnea strigosa) is found in open sites on branches and trunks of white spruce and other conifers, and on deciduous shrubs and trees, including oak trees. Its pale yellow-green branches may have a reddish brown central cord, but this bushy lichen is most easily identified in the field because its branch tips support round bristly discs of pale yellow or even pinkish. These are the fruiting bodies known as apothecia. This species is distributed worldwide including in eastern North America where it is at the northern edge of its range in Prince Edward Island. It is common throughout the Island but is still poorly documented by those who study lichens. As with other lichens, it may have medicinal properties, perhaps providing relief from a headache.

Pink Earth (Dibaeis baeomyces)

Pink Earth Lichen (Dibaeis baeomyces) is usually found on disturbed soil where competition from moss, herbs, shrubs and other lichens is limited. For example, it thrives on well-drained road banks in full sun where it helps to hold soil in place and build more soil. The whitish grey lichen body that covers the soil is called a thallus, and in this case it has a warty appearance. The fruiting bodies (apothecia) of the Pink Earth Lichen consist of a short stalk, about a half a centimetre, topped by a tiny turban of unmistakable pink. Its distribution is circumpolar in the northern hemisphere but in North America it is found mostly in the east. Though poorly documented on PEI by those who study lichens, it is common and can definitely be found throughout Prince Edward Island.

Frayed Ramalina (Ramalina roesleri)

Frayed Ramalina (Ramalina roesleri) is a lichen that structurally resembles a branch or twig. It is found especially on hardwoods and conifers near the coast and less often on rock or wood.  It is finely crafted in pale white to yellow-green with main branches about 2 mm in diameter and powdery growths at the tips, called soredia, that enable vegetative reproduction. In North America, the Frayed Ramalina is distributed mainly in Canada and it can be found in northern forests around the globe. It is common in Prince Edward Island where it has been found in coastal bogs and woodlands throughout, and in some interior woodlands. This lichen may have some medicinal benefits.

Lungwort (Lobaria pulmonaria)

Lungwort (Lobaria pulmonaria) is named for its lobed growth habit showing ridges and depressions like lobes of a lung. The lobes are as much as 12 cm wide and 7 cm broad. This lichen is found in shady locations on the trunks and branches of larger deciduous trees like maple and American Beech, and less commonly on conifers and mossy rocks. Lungwort has a tan to gray look when dry but is bright green when wet.  If in doubt as to its identity, simply pour water on it and watch it turn bright green. The underside is fuzzy orange brown with paler patches. Though one of the fastest growing lichens, it does not reproduce until about 25 years old. It contains several acids that discourage snails and slugs from eating it and is widely believed to have medicinal properties. It has also been used a source of dye. Over-collecting in some countries has contributed to its scarcity, and it is also affected by air pollution and acid rain. Car exhaust prevents its growth in urban forests. Lungwort is distributed in suitably moist habitats on four continents and throughout Prince Edward Island. It is regarded as a species typical of old deciduous and mixed forests.

This is your chance to select a lichen that well represents the environment of

Prince Edward Island.

March 3, 2020 meeting – Decline of  Eelgrass in Estuaries

At Nature PEI’s upcoming meeting, Dr. Michael van den Heuvel will discuss the decline of  eelgrass in Southern Gulf of St. Lawrence estuaries. Seagrasses are salt water adapted flowering plants that are threatened by human activities around the globe. In the Southern Gulf of St. Lawrence, eelgrass, the native seagrass is also impacted by human activities, particularly due to increases in nutrients from land-based activities. Dr. van den Heuvel will share the findings of a study conducted in local estuaries to determine the means to monitor changes to eelgrass health. Potential factors affecting eelgrass were examined, and it was determined that nitrogen loading was the dominant factor relating to eelgrass decline.

 Dr. van den Heuvel grew up in Northern Ontario and completed his undergraduate degree in Biochemistry at the University of Waterloo, and a PhD at the University of Waterloo where he started his research career studying chlorinated dioxins and furans and their effect on fishes exposed to pulp and paper mill effluent. After a post-doc studying aquatic reclamation in the oil sands, Dr. van den Heuvel immigrated to New Zealand and was employed by the New Zealand Forestry Research Institute where he worked on a variety of issues including pulp and paper effluent, nutrient enrichment and eutrophication and endocrine disruption.  Dr. van den Heuvel returned to Canada in 2005 for a Canada Research Chair in Watershed Ecological Integrity and for the past 14 years, Dr. van den Heuvel has worked on oil sands, pulp and paper, eutrophication, sediment effects, pesticides, fisheries, and environmental flows in Canada and PEI.

All are welcome to the Carriage House, Beaconsfield, Tuesday March 3 at 7:30 p.m. to meet Dr. van den Heuvel and learn more about eelgrass and the decline of this ecologically significant species in our local estuaries.

Birding Down Under – topic for Jan. 7, 2019

Nature PEI will be ushering in the New Year with their Annual General Meeting (AGM) and a  special  presentation on  “Birding Down Under”  with local naturalists Diane Griffin and Rosemary Curley.  Diane and Rosemary  will highlight their experience with an amazing variety of habitats and birds in Australia, profiling a small slice of the 850 Australian bird species from north Queensland to Tasmania and noting in passing some memorable moments with non-birds. Most bird species seen were endemic to Australia , but some familiar species were also encountered. A guided tour to 4 endangered species rounded out the expedition.

Diane and Rosemary are both graduates of Acadia University,and are long-time members of Nature PEI who have participated in the Maritime Breeding Bird Atlas projects, Christmas Bird Counts and backyard birding.  Diane is currently serving in the Senate of Canada and Rosemary is co-author of a recent book on PEI mammals.

All are welcome to join us at the Carriage House, Beaconsfield, Tuesday, January 7th at 7:30 p.m. to meet Diane and Rosemary and learn more about Australia’s unique birdlife.

Beaconsfield is located at the corner of West and Kent St. in Charlottetown.

Christmas List

If anyone hasn’t acquired the latest addition to their collection of Prince Edward Island books – The Mammals of PEI and Adjacent Marine Waters, published by Island Studies Press is available in better bookstores and is an excellent documentation of the mammals who have called PEI and surrounding waters home in the past and currently. Richly illustrated with maps photographs and artwork, no home library is complete without a copy.

Mammals of PEI

This community-supported book would not have been possible without the sponsorship of: Nature PEI, the PEI Museum and Heritage Foundation, the PEI Wildlife Conservation Fund, PEI Forests, Fish, and Wildlife, and Purity Dairy.  We wish to acknowledge with great gratitude all the organizations and individuals that made this book a reality including:

The impact of outdoor cats on native wildlife species.

Recent research on the impact of outdoor cats on native wildlife species has been revealing and Nature PEI was pleased to share this research with the public in October 2019 when Dr. Dave McRuer, a wildlife health specialist employed by Parks Canada and based at the Atlantic Veterinary College (AVC) in Charlottetown, PEI, was our guest speaker.

With both media and public interest in this topic remaining high we have decided to make available the slides from the presentation through our website.

Here is the presentation in .pdf format.
