My journey to becoming a Field Botanist

As a child I used to explore Cavendish Park (inside yellow circle) - a 12 hectare site located in the City of London, Ontario, Canada:



I would hide there to play hooky (truant) from school.  Convenient because it was down the street from my late grandmother's house on Cavendish Crescent.  Ironically, it became my place of employment from 1995 to 2003.  In 1995 I began teaching plant identification (ID) at Cavendish Park to volunteers and people receiving Employment Insurance (EI) benefits from the government.  At the time there weren't many resources available.  I scoured universities, libraries and book stores searching for field guides, technical manuals and papers on plant ID.  

In 2001 I led a research expedition to Nepal in search of medicinal plants, but forgot to bring the field guides I had purchased from my extensive search for plant ID resources.  I was forced to find another method to teach the 9 volunteers I had recruited.  A PhD trained Botanist from a university in Nepal accompanied us along with a team of Sherpa guides, our host and cooks as we traversed the foothills of the Himalayans between Kathmandu and the southern Terai region, Nepal.  

My thorough study and memorization of the content of my field guides paid off as I began teaching based on visual cues and characteristics.  While in Nepal I developed a course designed to identify to family level according to flower color, leaf arrangement, shape and number of petals.  This is how my Level 1 terrestrial and wetland plant course was born.

Meanwhile, from1999 and 2003 I led hikes with my students, employees and volunteers to survey all flora and fauna of the Bruce Trail between Tobermory and Owen Sound, Ontario, Canada.  I published the results in a field guide book in 2005 and called it "A Hiker's Guide to the Flora and Fauna of the Niagara Escarpment World Biosphere Reserve: Tobermory to Owen Sound":


By 2004 my plant courses gained popularity because I was helping people find jobs successfully in the environmental industry.  With encouragement from the government of Canada the EARTHQUEST Biological Field School came into fruition in June, 2005 when we opened our doors at Pinecroft, near Aylmer, Ontario, Canada:


For the next 5 years I taught out of a log cabin at Pinecroft.  We were free to explore the 22 ha property.  Thanks to the wonderful staff and owners at Pinecroft my field botany courses expanded into my Level 2 terrestrial and wetland plant course.


In the summer of 2008 - Rhonda Donley - a former student and co-author of the Ontario Management Plans for Special Concern Broad Beech Fern (Phegopteris hexagonoptera) and Green Dragon (Arisaema dracontium) obtained a job at Point Pelee National Park.  Subsequently, she invited my students and I to conduct Species at Risk (SAR) plant surveys on Middle Island, Lake Erie - one of the most southern points in Canada.  While conducting surveys on the island I got a call from a collegue and friend - Leigh Whyte to work on several wind farm projects in Orangeville, Ontario, Canada.  It was the launch of my career into environmental consulting and SAR plants.


My Level 3 SAR plants of Ontario plus Level 3 Asters and Goldenrods of Ontario emerged from my consulting work in Ontario to assist practioners with their work:




I have given a number of talks to local nature clubs and led hikes to demonstrate the concepts and principles of my plant field guide books.  Some of which have been mentioned in this blog:


As I look back at the path I took to learn how to ID vascular plants to the family, genus and species level and later teach to those interested in upgrading their skills I am grateful to have met and worked with so many individuals along the way.  Many of whom have gone on to their own successful careers.  Some also feel in love with plants.

Field Botanists of Ontario hike to Port Burwell Provincial Park

On Sunday August 12 Dave Jolly led a Field Botanists of Ontario (FBO) hike through Port Burwell Provincial Park.  The hike started with an orientation and introduction to the Park, ecological studies performed to data, history and information about the Discovery Park by Park staff.  This was followed by a stroll through the Carolinian forest on Ravine Trail in search of examples of vascular plants recorded during the 2016 Ecological Land Classification (ELC) and vegetation survey work.

A total of 26 new vascular plant species were added to the updated master plant list for the Park. This list of 464 taxa breaking down to 450 species (4 varieties, 5 hybrids and 5 sub-species).  Of these, the Park now boosts three Species at Risk (SAR), 5 provincially rare (i.e., species of conservation concern), 21 regionally rare (within the Carolinian forest region) and 30 locally rare (within Elgin county).  The official list was passed onto Park staff and the Discovery Program coordinator for Ontario Parks with the goal of publishing a pamphlet for Park patrons courtesy of EARTHQUEST (Canada) for the Environment.

April 2018 plant hunt summary

Entering our 12th season collecting data for the master EARTHQUEST plant database with 112,000 records the first plant of the season was a Skunk Cabbage (Symplocarpus foetidus) recorded flowering on February 1st.

April was a long, cold, and lingering month for the flora of Ontario.  We had the coldest April since the master database began in 2006.  The spring was delayed by two weeks in most areas with only 33 species recorded across 16 counties and municipalities of Ontario.

With the addition of 4 new plants for Renfew county the amount of coverage for this municipality is slowly rising.

The rarest plant was Harbinger-of-Spring (Erigenia bulbosa) observed on April 22, 2018 in Elgin county - approximately 2.5 weeks behind the onset of the normal flowering period.  No insect pollinators were observed visiting this plant.

Talk on Ontario's Orchids at Vienna Community Centre

Orchids are among the most beautiful and fragile flowers on the planet.  They range in size from the largest - the Queen of Orchids (Grammatophyllum speciosum) at a staggering 5.5 m in height to the smallest - measuring 0.5 mm, discovered in Brazil in 2015 - known as Campylocentrum insulare.  

Over 30,000 species exist in the world.

In Ontario there are over 50 species, most of these reside within the Bruce peninsula.  My personal favourite is Ram's-head Lady's-slipper (Cypripedium arientinum), which favours sandy sites among pines.

Ontario's threatened plant - Goldenseal - now has a recovery strategy

Over the past couple of years EARTHQUEST staff worked diligently with other plant species experts to write a recovery strategy for Ontario's population of threatened Goldenseal (Hydrastis canadensis).

                                                      Three year old plant                                                       Photo: Dave Jolly


Goldenseal is one of 72 vascular plant species listed on the Ontario Ministry of Natural Resources and Forestry (MNRF) Species at Risk in Ontario (SARO) site; https://www.ontario.ca/environment-and-energy/species-risk-ontario-list.  A recovery strategy is a provincial document that identifies the challenges facing species of plants and animals listed on the Ontario SARO list and provides recommendations for their recovery.

The MNRF recovery strategy for Goldenseal was published in May, 2016.  The document identified 24 naturally occurring populations with 79 colonies within the province of Ontario amounting to a total of 76,053 stems.  Two populations with 2 colonies were considered to be non-native in origin and, therefore, not protected under the Ontario Endangered Species Act and Ontario Regulation 242/08.  Two populations with 2 colonies were not assigned an Element Occurrence (EO) by the Natural Heritage Information Centre (NHIC) in Peterborough, Ontario, Canada.  The "element" is defined as an element of biodiversity.  This is the basic taxonomic unit on which NHIC compiles information: species (including subspecies, varieties and some hybrids), ecological communities, and wildlife concentration areas.

At least 2 out of 20 natural populations are threatened by illegal harvesting for their medicinal properties.

Details about the recovery strategy were also posted on the EARTHQUEST (Canada) for the Environment website.

Dave Jolly, the author of the provincial recovery strategy, was contacted by the author of the federal recovery strategy with Environment Canada in August, 2016.  Mr. Jolly was notified that 12 NHIC EO populations with at least 12 colonies were unaccounted for in the provincial recovery strategy.  All unaccounted EOs were historical records with 1 extant - last visited on June 10, 2010.  One population was in Essex region, 6 in Halton region, 3 in Huron county, 1 in Middlesex county, and 1 in Niagara region.

Beginning in August, 2016 Mr. Jolly endeavoured to conduct site visits to all EOs missed in the MNRF provincial recovery strategy.  On August 22, 2016 he visited the Niagara region site which yielded no results.  Subsequently, on May 13, June 28, and August 19, 2017 he visited 3 out of 6 sites in Halton region.  Talia Plaskett and Mr. Jolly visited another site in Halton region on September 23, 2017.  None of these historical sites confirmed Goldenseal.  Lastly, on October 14, 2017 Talia and Mr. Jolly visited the Middlesex county population and located 65 stems (17 plants).  One of these had a 3-leaved plant (i.e., at least 6 years old).  This confirmed this site as extant.  This data was shared with Environment Canada and will later go to the MNRF.

The remaining 7 historical populations of Goldenseal are planned to be visited in 2018.  It is hoped that future recovery strategy writers will contact Mr. Jolly to receive the most up-to-date information on these populations.

Talk at Norfolk Public Library & Chapters in London: Aster & Goldenrods of Ontario

Scheduled for Saturday October 28, 2017 from 1:30 pm to 3:00 pm at the Norfolk Public Library, 46 Colborne Street, Simcoe, Ontario, will be a talk and signing for our Asters and Goldenrods of Ontario book.  This will be a free event and open to the public.  Families with children welcome.

Another talk is scheduled for Sunday October 22, 2017 at the Chapters on Wellington Road South in London, Ontario.  The time will be from 12 N to 4 pm with book signing and a presentation on how to attract butterflies to your garden by planting asters and goldenrods.

Dave Jolly at Chapters Store in London, Ontario, Canada


The speaker will be Dave Jolly of EARTHQUEST (Canada) for the Environment and the EARTHQUEST Biological Field School.  Armed with 22 years of field experience and his B.Sc. degree from the University of Western Ontario Dave spent the last 13 years studying and photographing asters and goldenrods in their natural environment.  As a professional Ecologist he is considered a botanical expert on vascular plants and habitat restoration projects for insect pollinators and butterflies.  He has written several field guides on flora and fauna and was commissioned by the Ontario Ministry of Natural Resources and Forestry to write the recovery strategy for threatened Goldenseal.  To add to his botany porfolio on Ontario asters and goldenrods he has personally observed 53 taxa (5 hybrids, 1 variety) of these unique plants, including 5 Species at Risk, and 8 provincially rare.

In addition to Dave's contributions, a total of 252 plant records were recorded since April, 2006, collected by 26 students, volunteers, and staff from EARTHQUEST (Canada) for the Environment and the EARTHQUEST Biological Field School.

The Asters and Goldenrods of Ontario book showcases 34 species, 2 varieties, including 6 Ontario Species at Risk (SAR) based on visual cues.  It includes a binomial key for differentiating this confusing group according to flower colour, flowerhead arrangement, leaf width, venation and habitat characteristics.


The talks will cover topics in propagation for bee pollinator and restoration projects, how to select plants for butterfly gardens, as well as how to field identify plants as you walk through a woodland, forest, meadow, or wetland.

For those interested in purchasing a copy of our book the cost is $35 Canadian dollars plus shipping and handling.  Simply click on the Paypal link on the Asters and Goldenrods of Ontario book page, or contact us at: earthquestcanada@yahoo.com. Tel: 226-926-1470.
