April 22/24 – Fiona Parker of the Atlantic Conservation Data Centre: Flora & Lichens of Blue Mountain – Birch Cove

Fiona Brooks of the Atlantic Canada Conservation Data Centre takes us through the research they did in 2023 on the flora and lichens of the Blue Mountain – Birch Cove Lakes Wilderness area.

March 25/24 – Rebecca Parker Gets Us Up to Date with The Young Naturalists Club

Rebecca (Becky) Parker is Executive Director at Nature Nova Scotia and helps run the Nova Scotia Young Naturalist’s Club. She will talk to us about their activities including the multi day expedition to SW NS in 2021 with the YNC’s older youth chapter, where they worked on various plant surveys. They found and recorded field notes on species like redroot, goldencrest, and thread-leaved sundew. After returning home they then compiled their observations and drawings into the Kids Guide to Weird Plants book, which the YNC now distributes.

They repeated the trip in 2023 and chose educational signage as their science communication topic, drafting signs that could be placed in and around national or provincial parks in the area. They’re hoping to make that a reality this or next year, but really the best part of both trips has been just letting the kids explore and draw and ask questions.

Feb 26/24 Presentation – Mike Lancaster shows us the new Island Lake Wilderness Area

Mike Lancaster, Executive Director of the St. Margaret’s Bay Stewardship Association, takes us on a virtual tour of the newly designated Island Lake Wilderness Area, a 3,927-hectare Protected Area in the St. Margaret’s Bay Area and part of the broader Ingram River Wilderness Area proposal. Mike also discusses the 8-year campaign that this designation required and the need for continued support for the 11,000 hectares of the proposed Ingram River Wilderness Area that remains unprotected. The recording was delayed, so the first few seconds of the talk are missing.

Nov 27/23 Presentation – Nina Newington and the Save Our Old Forests campaign

Nina Newington and other citizen scientists are playing a key role in the effort to protect the proposed Goldsmith Lake Wilderness Area in Annapolis County. To date they have identified 27 Species At Risk occurrences (principally lichens), halting logging operations for now. They recently discovered an area of old-growth forest where DNRR maps showed only forest under 80 years old. Nina will present an overview of their explorations and the Save Our Old Forests campaign which recently expanded to include Halifax County.

Oct. 23/23 Presentation –  Fires, Conservation and Fire Management in the Halifax Backlands

Online presentation by David Patriquin to the NS Wild Flora Society.

The “Backlands”, located only a few kilometers from from peninsular Halifax, NS, are a Thompsonesque urban wilderness of approximately 1350 hectares which include nine lakes, hills with spectacular views and dozens of kilometers of informal hiking and biking trails. Erratic blocks, whalebacks and boulder fields are prominent features of the glacially scoured rocky landscape. It is also one of the most fire-susceptible landscapes in Nova Scotia, with recurrent fires pre-dating European settlement. One result is the presence of highly fire-adapted plant communities including the globally rare ‘Jack Pine/Broom Crowberry Barrens’.

David will describe the plant communities, their fire ecology, and discuss what’s involved in managing fire to conserve these ecosystems while at the same time protecting structures and people at the Urban-Wildland Interface.

For more about the area, visit

David Patriquin, Professor of Biology at Dalhousie University (retired 2008) is involved in conservation-oriented activities with several local natural history, trail and environmental organizations.

Sep 25, 2023 Laugavegur Trail, Iceland

Apr 24/23  Presentation – ACCDC Field Work in 2022

Burke Korol and Iain Crowell of the Atlantic Canada Conservation Data Centre give a presentation of their most recent activities documenting the flora of the Maritimes.

Mar 27/23  Presentation – The Logic of Black Ash

Many people have never seen a black ash tree. As Ecologist Nick Hill says “truth told, I was in my fourth decade of Nova Scotian botanical fieldwork before I noticed one. Why?”

The black ash, “wisqoq” of the Mi’kmaq, can be large bottomland trees in the Great Lake states and along the St John River but there is only a scattering in Nova Scotia and they are rarest in the acidic southern uplands. Nick will summarize and interpret the findings of the latest field research and try to answer:
Why is the black ash rare?
How can it survive?

Nick Hill PhD has worked Post-Doctorate and as an Associate Professor in Botany/Ecology. He is currently a self employed Consultant Ecologist and has Adjunct Status at Dalhousie and St. FX Universities

He has been Project Coordinator for: 1. Bog Restoration, Globally Imperilled Avens, 2. Wetland delineation and assessment, 2. Botanical inventories (rare plants), 3. Ecological assessments , Monitoring, Restoration analyses, 4. Wetland training courses

Feb 27/23  Presentation – Botanical Tales and Climate Change in Nova Scotia

David Garbary is a Professor of Biology at St. Francis Xavier University in Antigonish. He gives a talk to our members about climate change in Nova Scotia. This is from published work where Nick Hill and he looked at the temperature record for the province starting around 1960. He then explored how wind and storms have changed over the same period. This is new work that he is currently preparing for publication. To conclude, David relates climate change to a couple of plant stories including late flowering plants, some changes in the seaweed flora, and the implications for Eastern Mountain Avens (Geum peckii).

March 28/22 Presentation: Eastern Dwarf Mistletoe in Nova Scotia.

Bob Guscott gives a talk on the identification, biology, distribution and ecology of Eastern Dwarf Mistletoe at our member’s Zoom meeting on March 28. Bob is retired after 30 years with the Nova Scotia Dept. of Natural Resources as a Chief Technician and GIS Analyst. He lives in Wellington and remains an active volunteer and a keen naturalist

Eastern Dwarf Mistletoe Arceuthobium pusillum, is a little known and often overlooked, native, parasitic plant. It is found primarily on spruce trees throughout Nova Scotia, often along the coasts and in treed bogs. It is tiny but it can have a huge impact on the health of spruce forests in Nova Scotia.

Feb 28/22 Presentation: An Introduction to iNaturalist and the City Nature Challenge.

iNaturalist is a recognized citizen science program. It is led by the Canadian Wildlife Federation (CWF) along with Parks Canada, NatureServe Canada and the Royal Ontario Museum (ROM), which collectively make up the iNaturalist Canada Steering Committee. The platform is managed by the steering committee in collaboration with which is a joint initiative of the California Academy of Sciences and the National Geographic Society.

The primary objective of iNaturalist is to help people connect with Nature.

In 2019 to help introduce iNat to Nova Scotians HRM was registered to participate in the global City Nature Challenge. The following year three areas in NS were registered. In 2022 HRM, CBRM, and the Valley (Kings and Annapolis Counties) are once again registered to participate. This 4-day event is an excellent opportunity to encourage people to get outdoors, to explore, to observe nature, to share observations, and to have fun.

Prior to the 2022 CNC event local groups such as the WFS are encouraged to browse and review existing observations and provide feedback on ways to improve content. A quick review filtered for plants with locations in Nova Scotia shows 207,712 observations of 2,633 species from 7509 observers. Over 3000 members helped suggest names for these observations.

Use this presentation to learn how to explore content, how to create your own account, how to share observations (old and new), and how to comment on observations shared by others. Learn how to contribute to projects and how to provide feedback on how to improve content associated with wild flora.

Here is the text of the Chat that was ongoing during the presentation
