Ecologist Paul Keddy to share his passion for Lanark County’s natural heritage and special places

MVFN’s lecture series From the Ground, Up: Celebrating the Mississippi Valley Field Naturalists’ First 20 Years continues Thursday, October 16th. The lecture Earth, Water, Fire: Lanark County’s Natural Heritage by Canadian ecologist Paul Keddy, should open hearts and minds to the inherent natural beauty of Lanark County.

Dr. Paul Keddy has been a Professor of Biology at the University of Guelph, University of Ottawa and Southeastern Louisiana University. He is author of several prize-winning books on ecology and a recipient of a National Wetlands Award for Science Research. Although his career studying wetlands, forests and other upland communities has taken him around Ontario and far away to the swamps of Louisiana, his love and appreciation for the local Lanark natural environment has been ever present. So much so that in 1999 he wrote Earth, Water, Fire: An Ecological Profile of Lanark County, one of the most comprehensive books on the ecology of our area – a must-read for newcomers and a plea to protect natural spaces. Paul Keddy continues to champion local natural conservation efforts and occasionally lead nature walks.

In some ways, Lanark County can be thought of as a model in miniature for all of Eastern Ontario. Regions once flooded by the Champlain Sea share features with areas east to Montreal. Landforms and forests of the northwestern parts are reminiscent of Algonquin Park, and some areas of rich agricultural land are not unlike southern Ontario. In other ways, Lanark County is unique. The number of breeding birds is higher here than almost anywhere else in Ontario. The Frontenac Axis rivals the Niagara Escarpment in its beauty and biological significance. It is gratifying and exciting to learn more about the special and often fragile places here – areas where the loggerhead shrike may nest, the Purdon Orchid Fen, Pakenham Mountain, and Wolf Grove, to name a few. As we explore Lanark, we will see which of its features are typical of the Ottawa Valley, and which are unique.

The lecture by Paul Keddy takes place at 7:30 PM, October 16th at the Almonte United Church, 106 Elgin St., Almonte. Free for MVFN members and $5 for guests. All are welcome. For further information, please contact MVFN’s Program Chair Cathy Keddy at 613-257-3089 or see MVFN’s website at .

From the Ground, Up: Celebrating Mississippi Valley Field Naturalists First 20 Years

From the Ground, Up: Celebrating the Mississippi Valley Field Naturalists’ First 20 Years

The Mississippi Valley Field Naturalists’ (MVFN) lecture series this year proudly celebrates the club’s first 20 years by looking at local natural heritage, literally from the ground up! The Fall lecture series gets underway September 18, 2008 with Geodiversity: The Foundation for Biodiversity, a lecture by Allan Donaldson, Chair of the Friends of Canadian Geoheritage, and Professor Emeritus, Carleton University.

Did you know that where we walk today was once the heart of a mountain buried beneath 30 km of rock, or flooded by the sea? From gneiss to marble, hills to valleys, and clay plains to rock barrens… is it any wonder that such extraordinary geodiversity gives rise to Lanark County’s astonishing biodiversity? To appreciate the rocks that form our familiar landscape, bring your imagination to this presentation by Dr. Donaldson for a journey far back in time to the ocean depths, erupting volcanoes, colliding and splitting continents, and a landscape locked in ice.

Then in October the lecture series continues with, Earth, Water, Fire: Our Natural Heritage a lecture by Ecologist, Dr. Paul Keddy, which will explore the unique beauty and ecology of our region- one often overlooked by outsiders and taken for granted by those who live here.

Dates for all the lectures in this years series are listed below and full details for each lecture will be posted here. Lectures are held on the third Thursday of the month (with a break for December) and begin at 7:30 pm at the Almonte United Church. All are welcome, with a $5 charge for non-members. For further information on the lecture series please contact MVFN’s Program Chair, Cathy Kedddy at 613-257-3089.

Cliff Bennett and the new Atlas of the Breeding Birds of Ontario

The new Atlas of the Breeding Birds of Ontario,

Press release Feb 25, 2008

The Appleton Square number 18VR10 was completed by MVFN

A large crowd was in attendance for “Birds: Changes and Challenges Around Us” a lecture hosted by the Mississippi Valley Field Naturalist’s (MVFN) February 21st in Almonte. The lecture, 5th in MVFN’s “Our Natural World: Conservation Challenges” series, was presented by Cliff Bennett, local bird columnist and current Eastern Regional Director for Ontario Nature (ON).

Our speaker was given a warm introduction by Brenda Boyd, MVFN’s ON Representative and Director for Membership. Still a classroom teacher at heart, Cliff began his presentation with a ‘test your knowledge’ surprise slide-show quiz to name the bird on the screen. Four ‘experts’ in the audience tied with 10/11 correct answers and one lucky expert was presented with a prize of a wooden blue bird box.

Great inspiration for the lecture was taken from the January launch of the Atlas of the Breeding Birds of Ontario 2001-2005. Cliff Bennett has been following birds for many years and was very pleased to be able to present some of the findings in the new Atlas to the audience. Cliff explained that there are many ways citizens help track bird species and abundance e.g. Christmas bird counts, Backyard Bird Counts, Marsh Monitoring, Loon Watch, etc. However, by far the most impressive recent example is the Ontario Breeding Bird Survey which tracks birds which breed in Ontario.

The Ontario Breeding Bird Atlas includes > 75% of all birds breeding in Canada. The second edition of this survey summarizes 5 years of observations and was just released in a launch at the Canadian Museum of Nature in January 2008. The data was compiled and analyzed by professionals but the huge amount of data collected over the five years represents the combined effort of more than 3000 people logging some 153, 000 hours watching birds looking for evidence of breeding. The province was divided into about 14,000 ten km squares including the ‘Appleton’ square or square 18VR10 which MVFN was responsible for.

Cliff summed up some of the fascinating facts found in this Atlas which differed from the first Atlas of 20 years ago. Some birds such as house finches, blue-headed vireos, Canada geese, turkey vultures and wild turkeys expanded their ranges considerably. All raptors increased significantly except for great horned owl. The most widespread bird, found in 91% of the squares, was the white throated sparrow. In addition to the range of birds, the data also allows estimates of overall numbers in the province. For example some of the most abundant birds include Nashville warblers at 15 million and red eyed vireos at 9 million.

Generally more forest bird species increased in population than decreased. This probably reflects land taken out of agricultural use. For grassland birds there were more decreases than increases. There was a slight increase in wetland birds. There were more decreases than increases in shrub and early succession birds. Significant decreases however were noted for all aerial foragers. This includes species such as night hawks (seen in 545 fewer squares), chimney swifts, martins and whip-poor-wills.

In some cases where other parts of Ontario saw declines, we saw increases locally. As someone who is contacted daily with bird reports from the local area, Cliff has already noticed more changes since the atlas. For example blue birds locally may now be on the decline.

Adverse human attitude towards birds, explained Bennett, is a major factor in conservation challenges. Our avian friends are facing significant challenges not only from deforestation in the tropics, but in Ontario from habitat destruction during large subdivision development, damage from pesticides, hazards to bird navigation from tall buildings, wind mills and excessive lighting. Many large developers claim “It is only a little bird.” However, Bennett pointed out that we need a healthy bird population for balance in our natural world. We need to learn as much as we can about birds.

All are invited to the next lecture in the “Our Natural World: Conservation Challenges” series. This session will focus on turtles and will be presented by David Seburn of Seburn Ecological Services, on Thursday March 20th at 7:30 pm at the Almonte United Church Social Hall in Almonte.
