Breaking news for 2017. Paul's latest book Plant Ecology has been published by Cambridge University Press in full colour. This book starts with the origin of plants and their role creating the biosphere, moves through key causal factors that control plant communities, and ends with chapters on plant diversity and plant conservation. There 13 chapters, over 300 illustrations, a glossary, review questions and suggested further readings. While the book is aimed at university students and scholars, the writing style and examples should make the book enjoyable for many non-specialists. Cambridge is now taking orders for this book at their web site here. There is also a page for Plant Ecology on this web site here.
May 2017. A concise guide to wetland restoration. The newly-published Routledge Handbook of Ecological and Environmental Restoration is a comprehensive guide to repairing damaged ecosystems. Paul contributed the chapter “Restoration of Freshwater Wetlands”
April 2017. Paul participated in a workshop at the Canada Centre for Inland Waters, to provide expert review of ongoing work on relationships between wetlands and water levels in Lake Ontario and the St. Lawrence River. This project is a significant example of applying the scientific principles of wetland ecology to the practical goal of restoring and protecting wetlands. The focus of the workshop was on measuring the benefits of the natural alternation of the lakes between high and low water levels. The second chapter of Wetland Ecology: Principles and Conservation describes how water level fluctuations produce wetlands on lakes in particular, and along watercourses altogether. The foundations for this CCIW work were laid back in 1986 in a scholarly paper (Keddy and Reznicek 1986) describing the relationships between water level fluctuations and wetlands in the Great Lakes.
February 2016. Paul's guide to the scientific literature on wetlands has now been published by Oxford Bibliographies in Environmental Science. This contribution begins with a general guide to introductory sources, particularly important books. The following sections will guide you to sources of information on more specific topics including flooding, nutrients, other causal factors, and geography. Two concluding sections give an overview of wetland conservation, and an introduction to the significance of aquatic plants. You can consult this guide online at Oxford Bibliographies here. If you are not working at a large research institution or library, you will have on-line access to only the introductory section. If so, you may view a version of the complete article on this web site here.

August 2015. Wonderful conservation news! The Nova Scotia Nature Trust has just announced yet another purchase of significant wild land with rare coastal plain plants, based upon field work and maps prepared by Paul several decades ago. This concentration of rare wetland plants was discovered on a canoe trip made back in 1982.

June 2015. Paul traveled to Providence, Rhode Island for the 2015 meeting of the Society of Wetland Scientists. Their primary mission is to promote understanding, scientifically based management and sustainable use of wetlands. This year’s theme was “Changing Climate, Changing Wetlands”. At this meeting, Paul was made a Fellow of the society, “the highest recognition of membership bestowed by the society”. He also gave a keynote address to open a symposium focused on using plant traits to carry out predictive modeling for wetlands and floodplains. His presentation was titled: “Functional Groups in Wetland and Riparian Plants: A Strategic Perspective”, and as he said in his talk, the challenge was to cover a hundred years of progress in just 15 minutes. A video of the talk will appear later this year.

May 2015. Paul received the prestigious W.E. Saunders award for natural history from Ontario Nature in recognition of his self-published guide Earth, Water, Fire: An Ecological Profile of Lanark County.
April 2015. Paul and Cathy Keddy received a conservation award from the Ottawa Field-Naturalists Club for their “land conservation achievements in the Lanark area”, particularly the donation of land and development rights to the Mississippi Madawaska Land Trust that created the Keddy Nature Sanctuary. This sanctuary protects hundreds of acres of Lanark County, including a large area of old hemlock forest, and more than a hundred acres of provincially significant wetland.

June 2014. Radio conversation. Paul was interviewed by Bob Perrault for Lake 88 on June 27. The topic was his donation of a square mile of forest and wetland to the Mississippi Madawaska Land Trust (see April news).

May 2014. Paul gave a talk to the annual general meeting of the Mississippi Lakes Association on 31 May. The title was Mississiipi Lake: Past Present and Future. The talk focused upon the ecological services provided by wetlands and the role of seasonal changes in water level for maintaining healthy wetlands. View the talk here.

March 2014. Paul spoke to the monthly meeting of the Ottawa Field- Naturalists' Club on March 11. The illustrated lecture was based on his popular book, "Earth, Water, Fire: An Ecological Profile of Lanark County".
February 2014. Paul gave a public talk on wetlands to the Mississippi Valley Field Naturalists. The main topics included (1) what wetlands are, (2) the four different kinds, (3) what their values are, and (4) some simple rules for their conservation. He also talked about local examples including the Mississippi Lake wetlands and the Appleton Swamp. This presentationwas based upon the first chapter of his book, Wetland Ecology: Principles and Conservation (Cambridge University Press, 2010).

September 2013. Paul gave the opening plenary address to Open Landscapes 2013, a conference in Germany which brought together researchers from around the world with an interest in wild, or semi-wild, landscapes. Paul's talk was titled "Restoring and maintaining biodiversity in semi-natural open landscapes: bridging the oceanic divide"

August 2012. Nothing is more embarrassing at a party, or a comprehensive exam, than finding people are talking about a scholar, or a field of knowledge, about which one is entirely ignorant. Really, one should just know about topics like Darwin’s finches, or Galapagos tortoises, or carnivorous plants, or peat bogs, just as one should know something about Beethoven or Shakespeare. But where you do start in your reading? Now available on line -- a guide to basic reading in ecology, from Dampier and Darwin to modern sources. Short essays with an annoted bibliography.
In the middle of May 2012. Paul spent two mornings with a film crew from Stornaway Productions who are working on a project tentatively called “Watershed”. They arrived at his home in the forest, and set up two cameras focused on one lone white chair, with a beaver pond in the background. The first morning with Paul in that chair was spent on the scientific principles underlying wetland ecology, particularly flooding and fertility, and the need for simple general principles to unify ecological research. A muskrat put in an appearance, voluntarily. The second morning was spent on the relationship between science and conservation, which led to a wide-ranging inquiry into how humans can appear to be blind to the consequences of their harmful actions. Topics included the fall of Troy, The March of Folly, Easter Island, and Hurricane Katrina.
1 May 2012. Over 120 people came to Arnprior to hear Paul give a public talk entitled "No Place Like Home in the Ottawa Valley" to the Macnamara Field Naturalists' Club. Drawing in part upon his book on Lanark County, and in part upon Wetland Ecology, Paul explored the importance of deciduous forests, the wetlands of the Ottawa River and introduced some of the most important natural areas in the region.
