The Peninsula Field Naturalists' mantra is to advocate, educate and participate in the conservation of natural resources and green spaces in Niagara and elsewhere. Our club hasachieved this in the past by coordinating a hike in a conservation area with the 9th Welland Cub Scouts, campaigning to preserve Niagara woodlots, and introducing a group of children from the Niagara Historical Society and Museum Kids Curators program to nature and bird watching.
More recently, the PFN presented a talk on conservation and birds at the St. Catharines Public Library. The presentation was aimed at older adults, retirees and seniors. And with a chat to girl guides on bird-watching to help them obtain a bird-watching badge in the works and future projects (Yes, future projects! More on that later.), I would say the PFN are doing a fine job in advocating, educating and participating in the conservation of natural resources and green spaces in Niagara. To all the members that have contributed to this effort, you have my thanks.

Trees – Our Warriors to Climate Change: by Loretta Shields
It’s ironic that with all the talk about global warming and climate change, why trees don’t get the attention they deserve. Trees provide so many ecological and economic benefits. More than half of the earth’s land based species require the habitat of trees and forests, so why aren’t trees more protected?
We need to think of trees as living “air conditioners”. American Forests.org claims each one of us requires two mature trees to produce our annual oxygen needs. Trees help to maintain water quality by absorbing pollutants, and regulating water levels during high rainfall events. After all, oxygen and water are two basic ingredients for life!
But trees have economic benefits also. During the heat of the summer, trees lower temperatures by transpiring water and shading surfaces, lowering energy costs for air conditioning by up to 30%. In the winter, depending on the direction of the prevailing winds, well positioned trees can significantly lower heating costs.
Another very important function of trees is their ability to sequester (bind) atmospheric carbon. Carbon dioxide (C02) is also known as a greenhouse gas. C02 absorbs infrared radiation that is emitted from the earth’s surface, thereby causing increased levels of infrared radiation in the lower atmosphere, which causes temperatures to rise. This is known as global warming.
As the earth’s population continues to grow, more carbon is emitted into the atmosphere from human activities such as burning fossil fuels and the manufacturing of electricity to heat homes, for transportation, and the production of cement for building projects. Carbon dioxide is also released into the atmosphere through the combustion and decomposition of plants and animals. The concentration of atmospheric carbon is currently greater than 400 parts per million.
Trees are able to remove more carbon from the atmosphere by photosynthesis than they return via respiration or decomposition and are considered a net carbon “sink”. Oceans and soil are also capable of absorbing carbon, but not quite to the same degree as forests.
But what happens to the carbon that a tree sequesters? The process of photosynthesis uses light energy to convert carbon dioxide into a carbohydrate. These carbohydrates are used to produce cellulose, which gives structure to cell walls and ultimately provides the upright structure to trees. Sequestration rates vary greatly according to the age, composition, and location of trees and the type of soil, but a general rule of thumb is that approximately 50% of the dry weight of a tree is carbon.
It is estimated that in 2009, the average American was responsible for 5190 kg of carbon emissions. How many trees would be required to sequester this amount of carbon on an annual basis? The US Forest Service has developed a Tree Carbon calculator. This tool calculates the amount of biomass and carbon stored in a tree, as well as the amount of carbon sequestered annually. Using this tool, one can estimate that over 680 white pine trees aged 25 years old would be needed to sequester the carbon emitted annually by one person according to the 2009 estimation. This illustration provides a better sense of our carbon emissions and the importance of trees in reducing the effects of climate change.
Trees need to be protected. But what are the ongoing threats to their existence? There are many insects and diseases that are affecting the livelihood of our tree population here in Ontario. The emerald ash borer continues to decimate the ash population throughout Ontario. Its spread can not be stopped, although parasitic wasps have been introduced and some do show promise in one day of reducing the emerald ash borer populations. Asian long-horned beetle was detected in Toronto near the Lester B Pearson international airport. Surveys continue every year to detect infected trees in the hope of soon declaring the region free from this insect. Oak wilt disease is a disease that predominantly affects red oak and is spread by nitidulid beetles. Oak wilt is detected in Michigan and New York State, and is a serious threat to red oak populations in Ontario.
Developmental projects pose imminent threats to tree populations in Niagara as well. The Irish Grove Woodlot in Grimsby, the Thundering Waters development project in Niagara Falls and the Lockhart Drive Forest in St. Catharines have been topics in local newspapers throughout 2017. The Niagara wind energy development project in West Lincoln, Wainfleet and Haldimand resulted in several thousands of trees destroyed to allow for the development of transmission lines and access roads. After a full year of operation, the project only provided 24% of its nameplate capacity in energy. Residents were initially told that roadside trees would be replaced, but there is no news of the replacement of the trees to date.
Trees need to be protected and people need to be aware of just how valuable
trees are in providing those life essential ingredients we take for granted
every day. Otherwise, their removal will continue to have a negative on our
( Loretta previously explained the importance of trees at the PFN November meeting, and graciously gave the above write-up to the “editor” for this version of “ The Peninsula Naturalist” – Thanks to you!! )
January 7, 2018 Lake Ontario Mid-Winter Waterfowl
Letter from John Black to Glenn Coady the Waterfowl
This had to be one of our coldest counts. The combination of -16 degrees at the start and the development of strong winds later in the morning made counting difficult on January 7. Most of the shoreline had a scrambled ice shelf to about 50-100 meters from shore. Beyond that there were leads in open areas but much of the ice extended out beyond scope limits.
16 observers participated in the count. We covered the Lake Ontario shore line, from 50 Point to Niagara on the Lake, and the Niagara River up to the falls. We also drove out on the east side of the Port Weller piers.
Four Bald Eagles were observed. (3 adults, 1 immature).
SPECIES AND NUMBERS: Total Waterfowl 8525:
Double-crested Cormorant 24; Tundra Swan 3; Mute Swan 30; Canada Goose 1081;
American Black Duck 15; Mallard 476; Gadwall 2; Greater Scaupe 3; Scaup (sp) 3;

Somehow the Peninsula Field Naturalists Club seems to have its ups and downs, much like many other clubs, organizations, and human endeavours in general. So, when a severe fog developed on Monday, January 22, 2018, and the expected speaker was unable to appear, the Club was fortunate to have a replacement amongst our local ranks. Thus:
Speaker: John Black: An Albatross Birding and Nature Tour in Chile
John’s companions on this trip were Marcie Jacklin, Lynne Freeman, and Ivor Williams. Their planned destination was to first spend some days in Santiago and vicinity, and next travel on to Patagonia and Tierra del Fuego. The intention was “an Albatross birding and nature tour” as John described it. After arriving and settling in Santiago, they went walking in a park where they saw a Austral Thrush. They also met a new guide, since their original guide had to help his family who were in a dangerous forest fires zone. On their second day, they went east from Santiago to a hilly ski resorting area, where they had some birding success. They saw or heard Cinerous Ground Tyrant, California Quail, Dusky-tailed Canastero, Moustached Turca, but had no success finding a Chilean Tinamou. At the Park Yerba Loca, they were not allowed to enter because of the fire dangers. They spent four more days in the Santiago area before flying south to Patagonia and Tierra del Fuego, at Punta Arenas (pronounced “Puntarena”) for six days of birding.
In the Punta Arenas area and in Tierra del Fuego, their group was guided by Cristofer De la Rivera Morales, and their driver Henry. In the Punta Arena area, they saw Upland Geese, Giant Petrel, Chilean Skua, Steamer Duck, and Black-browed Albatross and other birds as well.The group was ferried to Porvenir in Tierra del Fuego, and John mentioned that there was good birding at the Magellan Straits. There they saw Albatross, penguins, petrels, diving-petrels, skuas and giant–petrels and shearwaters. On the way to a lake they saw a beautiful Variable Hawk. At the lake, they found Magellenic Plovers (a new bird family to John) and watched them nearly an hour. In all, from January 26 to February 6, they had seen 177 species of birds on their trip, and John had added the Family of the Magellenic Plover to his family list. (Thanks to John for his fascinating travelogue!)
