From: UMaine Cooperative Extension’s “Maine Home Garden News”, October, 2019 https://extension.umaine.edu/gardening/2019/10/01/maine-home-garden-news-october-2019/
After acquiring what is now known as The McKeon Environmental Reserve, the Directors of the Mousam Way Land Trust endorsed the concept to plan and build a community ecology center. The David and Linda Pence Community Ecology Center, named after the generous folks who put the fundraising for Reserve property acquisition over the top, will include an Environmental Center where folks can hold meetings; a small workshop for making bird nesting boxes, bat houses, informational signs, and other eco-oriented projects; an environmental library, attuned towards school kids; an ADA-accessible outdoor restroom; an industrial-sized greenhouse; and a nursery to propagate various plants for the Nature Trail and other ongoing projects:
But I was asked to talk about another facet of the Eco-Center and the Reserve: The Sanford Community Garden.
Public outreach and environmental awareness being leading tenets of Mousam Way Land Trust’s operational directives, the Reserve’s field next to a barn, and a windmill-styled hand water pump connected to a very productive drilled well both sparked a vision within the prescient-minded Dr. Bud Johnston, Trust co-founder and long-time President. “Let’s build a community garden, an offering sorely lacking in the Sanford area.”
Recruiting public involvement is always an agenda item when Trust projects begin, and this was no different. University of Maine Cooperative Extension Master Gardener Volunteers (MGV) from York County worked with Bud to plan, design, budget, source materials, solicit other volunteers, build, and maintain Sanford Community Garden.
It was very quickly realized that substantial financing would be required, so Dr. Bud got to work researching grant possibilities and doing the quiet and tedious work of grant writing. Generous donors, organizations, and local businesses answered Bud’s call for help; and the Maine Master Gardener Development Board answered mine!
With sufficient funding, it was shopping time. A neighbor’s recently rehabbed portable sawmill and his abundant hemlock trees became the planks that formed the 27, 4-foot by 12-foot raised beds. A neighboring town’s sawmill supplied the composted soil, which tested perfect for the garden’s use. Deer fencing, posts, tools, water supply materials, nuts, bolts, screws, landscape fabric … we had plenty of toys to play with! “Playtime” began with a friendly plumber removing the old hand pump and installing a pressurized system, using the electrical service available in the barn. Trenches were dug, lines and cable run, and garden hose manifolds designed, built, and installed. The annual United Way Day of Caring (UWDOC) organization found some energetic folks to work alongside some pre-enrolled raised bed gardeners and Trust members in Maine’s rocky soil, driving heavy steel fence posts and digging deep holes for the corner and gate posts, which were expertly fashioned by experienced carpenters that just happened to be among the UWDOC folks. Unbelievable, right!
While the posts and gates were being placed, Master Gardener Volunteers (you thought they just grew plants, right!?) joined others to assemble the heavy, 10-inch-high raised beds in neat rows, and line them all with landscape fabric. A helpful neighbor drove his tractor from his farm through some of the Reserve’s 2 1/2 miles of woods trails to help fill the beds with rich soil as they were built. Yet even more volunteers raked the soil level in the beds as some volunteers’ kids played in a huge, 1/8 acre “sandpit” — actually a foundation for the donated greenhouse yet to be installed — blessed again by generous donors, but that’s a story for another time.
Anyway, the raised beds are built, filled with soil, surrounded with an 8-foot-tall, high-tensile steel deer fence tightly stretched around steel and wooden posts, 5-foot-wide gates are swinging open for access, wood chips from the on-going city road building project are spread along the fencing perimeter and between beds, and hundreds of seed packets and rather sickly-looking plants donated from local businesses were placed in the hands of excited gardeners.
Well, the sickly plants survived MGV-rehab wonderfully and, along with hundreds of seeds now sprouting and plenty of watering hoses to keep them all happy, we are also growing a bustling community garden. Some beds are assigned to folks who have been granted waivers due to financial challenges (the Trust asks for a $25 donation to help cover operational and maintenance costs); some are being tended by supervised adults with disabilities; some are under the watchful eyes of a local school’s food-for-kids program; others are tended by Master Gardener Volunteers for local food pantries. A few have gone unassigned and are sprouting buckwheat cover crop sown to enrich the soil even further.
Next spring, we won’t be waiting for the soil to thaw and dry to allow trucking it to a waterlogged, impassable road (did I mention that we needed to rebuild and gravel a couple hundred feet of road to allow access to the garden area?). And with the water supply available, we expect gardeners to fill up all the beds and are anticipating a waiting list. The future is bright and bountiful!
Baby Boomers, Gen-X’ers, Millennials, Gen-Z’ers are terms describing generational groups. Boomers frequently heard the singing of the whip-o-will, enjoyed streets lined with elm trees, and catching brookies in local streams. Gen-X’ers witnessed Dutch Elm devastate their streets; few Millennials are found who’ve heard the whip-o-will’s singing; the Gen-Z’ers’ brook trout have disappeared from their local streams. Environmental degradation levels increase with each generation, and each generation describes their observations as “the norm”, and thus compared today’s environmental condition with the memories of their youth. Rare is the elm without dead branches, and citizens rally to preserve it. “I just heard a whip-o-will!” is excitedly posted on social media, for those rare moments when the whirring nighttime song is heard. Week-long fishing trips “up north” are needed to “catch your limit” of the once common brookies.
In “The Once and Future World,” journalist J.B. MacKinnon cites records from recent centuries that hint at what has been lost: “In the North Atlantic, a school of cod stalls a tall ship in midocean; off Sydney, Australia, a ship’s captain sails from noon until sunset through pods of sperm whales as far as the eye can see; Pacific pioneers complain to the authorities that splashing salmon threaten to swamp their canoes.” There were reports of lions in the south of France, walruses at the mouth of the Thames, flocks of birds that took three days to fly overhead, as many as 100 blue whales in the Southern Ocean for every one that’s there now. “These are not sights from some ancient age of fire and ice,” MacKinnon writes. “We are talking about things seen by human eyes, recalled in human memory.”
So the current environmental condition is perceived as being normal. Historic conditions were normal for their times, but much different than now. “Shifting Baseline Syndrome” describes the bias inherent with the many “normal” comparisons related to natural trends. For example: during my youth, several whip-o-wills were commonly heard nightly; my kids heard maybe a few a month; my grandkids listened to them a few times in their lives. But each generation considers the whip-o-will population as being normal, but it’s actually rapidly decreasing. This results in the increasing levels of environmental degradation being accepted as the new normal.
Recent studies describing diminished species levels and lowered conditions of their health are beginning to highlight this phenomenon. Not until we step back a bit and peer into history do we realize the destruction happening, albeit in slow motion. It’s the Boiling Frog fable happening for real, to every living thing…Earth included. 80% insect declines in less than 3 decades; 29% bird decline since 1970; scientists describe the world-wide amphibian decline as an ongoing mass extinction event; the ocean’s phytoplankton populations and health are both declining, adding to Ocean Acidification and baseline food chain depletion…BASELINE FOOD CHAIN DEPLETION.
Scientists have been warning us that definitive actions of unprecedented levels are required to address this global warming emergency. It’s our world, current policies are destroying it, and the world-wide collective scientific community has something to say. Not listening, not planning, and not acting is not an option.
The Carbon Cycle
At the beginning of the Archean Eon 4 billion years ago, life emerged upon Earth in a process called abiogenesis; ie., “origin of life”. Several evolutionary processes at the molecular level of increasing complexity formed various chemicals in the early ocean, which led to cellular processes like self-replication and membrane formation. Bacteria eventually evolved and began adding oxygen to the existing volcanic gaseous atmosphere. (For a time, the bacteria went a bit crazy, creating “The Great Oxygenation Event”). Fungi, plants, and animals evolved…some crawling onto land. Plants took root, making homes for the evolving insects, amphibians, reptiles, birds, and mammals. At the atomic level of all this is carbon. Carbon loves to bond with other elements, and is the best element able to form the long chains needed for complex molecules, like DNA. So, Earth is host to carbon-based life…
…and The Carbon Cycle.
Living things breath. Plants “inhale” carbon dioxide, add water, and with the sun’s energy use a process called photosynthesis to make sugars. The plant “exhales” oxygen. The plant grows, using up atmospheric carbon. The plants get eaten by animals. Their life processes…breathing, waste-production…release the carbon back into the air and soil. Plants and animals die, get eaten by carrion eaters and macro- and micro-organisms, releasing more carbon. The remaining soil-based carbon is sequestered for 100’s of millions of years, forming reservoirs of peat, coal, oil shale, natural gas, and oil deposits.
Atmospheric carbon also dissolves into the oceans, which hold up to 50 times more carbon than the atmosphere. The tiny plants of the oceans, phytoplankton, eat some of the carbon via photosynthesis. Other things eat the plankton, other things eat the other things, etc.; all these things eventually die, drifting to the ocean bottom. The layers of sediment form an organic-rich mud and the pressure compresses it into organic shale and limestone. Through millions of years the layers continue to sink. Heat and pressure transform the shale into oil shale. Oil percolates from the shale, upwards through the other relatively porous layers and groundwater, until it meets a solid rock layer. Thus, another method of carbon sequestration. Carbon also get stored in the rock layers thus formed. This is all naturally in balance….
…WAS naturally in balance.
The actions of anthropogenic (human) activities…burning of carbon-based materials (fossil fuels) removed from the sequestered carbon reservoirs…releases carbon back into the atmosphere as CO2 which disrupts the carbon cycle in ways severely detrimental to human existence, and the existence of most other things.
Let’s begin with the air we breath.
Land-based plants and the oceans are currently managing to take up about 80% of the carbon generated anthropogenically (by humans). The rest stays in the atmosphere for thousands of years. Scientists have found that CO2 causes 20% of Earth’s greenhouse effect, water vapor 50%, and clouds 25%; other things make up the rest.
Earth’s atmosphere is a thin blanket of gases and tiny particles where water vapor levels are controlled by temperature: higher temps equal more water. CO2, and other materials, heats the air by absorbing solar energy then releasing it. So as CO2 atmospheric levels rise, water concentrations increase due to the increase in temps. The increase in water concentration adds to the greenhouse effect, further increasing temps, further increasing water levels, further increasing the greenhouse effect, etc. The Earth is heating up on a global scale: Global Warming.
As carbon enters an environment, it combines with tiny water droplets to form carbonic acid. As the air cools, retained water get released it as rain..all precipitation begins as rain…and the rain holds the aforementioned carbonic acid, adding to the acid caused by other pollutants, creating “Acid Rain”. Acid rain disrupts plant growth and aids in mineral breakdown. As rock is degraded, the carbon stored there 100’s of millions of years ago gets released, adding more carbon to the Earth’s carbon cycle. So of all the greenhouse gases, CO2 is the gas that regulates the Earth’s temperature more than any other, thus controlling the both size of Earth’s Greenhouse Effect and the speed of Global Warming. And Earth’s atmosphere is getting wetter, creating closer ties with the oceans.
The Oceans, you say?
As carbon as CO2 enters the oceans, the carbonic acid created is soon converted into bicarbonate, lowering the ph level and, worldwide, causing Ocean Acidification. Higher atmospheric CO2 levels are causing an increase in these actions, resulting in an increase in species mortality; various sea creatures suffer depressed metabolic and immune response rates. Oysters, clams, and shallow and deep sea corals experience higher mortality rates.
Plankton, the basis of the ocean food chain, which happens to add 50% of Earth’s oxygen to our air, also suffers. Studies have shown negative effects of ocean acidification on plankton. Zooplankton species have calcium-based protective “shells” which do not properly form in an acidified environment. Phytoplankton photosynthesize and need chlorophyll; chlorophyll health suffers in an acidic solution. Some species of phytoplankton cannot survive in acidic and warm environments…and that’s what’s now happening. So, plankton diversity may decrease and species’ population will redistribute as they adapt to changing conditions. The implications of population redistribution and decreased diversity will disrupt the ecosystem and the food chain in ways now not fully understood.
So, we’ve disrupted the carbon cycle, adding atmospheric carbon faster than the normal carbon cycle can address it. Acid Rain, Greenhouse Effect, Global Warming, Climate Change, Ocean Acidification, Bug Die-Off, Diminished Species: all terms coined in my generation. The latest term?…
The Sixth Extinction
Five mass extinction events during the past 540 million years have happened, all involving worldwide extermination of marine species over the course of thousands to millions of years. Each event was preceded by major changes in Earth’s carbon cycle…a change we currently seem to be experiencing. Some scientists point to carbon cycle data suggesting that the sixth event may very well be happening now. The difficultly is that previous cycle data have spanned thousands or millions of years, while the current data base involves only a century or so. The magnitude of our current carbon cycle needs deeper study…
…which has been done.
Daniel Rothman, professor of geophysics in the MIT Department of Earth, Atmospheric and Planetary Sciences and co-director of MIT’s Lorenz Center, has published an article in Scientific Advances, identifying “thresholds of catastrophe” in carbon cycles which, if exceeded, would lead to an increasingly unstable atmosphere, and as his data shows, mass extinction.
Rothman found that the critical rate for catastrophe is related to a process within the Earth’s natural carbon cycle, in which organic carbon sinks to the ocean bottom and is buried and becomes sequestered. If this rate of natural sequestration is exceeded by carbon being added to the cycle…by burning fossil fuels for example…the carbon cycle becomes unstable.
His study shows that historic mass extinction follows if one of two carbon cycle thresholds are crossed: long cycles with relatively slow carbon level changes that happen faster than Earth environments can adapt; and short cycles with a relatively quick, high level change. The latter change is what we are now experiencing; excess carbon circulating through the oceans and atmosphere, resulting in global warming and ocean acidification.
His study indicates the crossing of the carbon threshold by 2100, using projections in the most recent report of the Intergovernmental Panel on Climate Change. IPCC considers various politically-enacted carbon emission-limit policy scenarios in their models, which all show that by 2100, the carbon cycle will either be close to or well beyond the threshold for catastrophe.
“This is not saying that disaster occurs the next day,” Rothman says. “It’s saying that, if left unchecked, the carbon cycle would move into a realm which would be no longer stable, and would behave in a way that would be difficult to predict. In the geologic past, this type of behavior is associated with mass extinction.”
“When the caterpillar is a full grown fifth instar caterpillar it is ready to molt the fifth time to become a pupa, or chrysalis. The caterpillar will begin to wander until it finds an appropriate place to create its chrysalis. It will lay down a silk mat, like it has every time that it has molted before. But this time it will spend time creating a small wad of silk–a silk button—in the middle of its mat. When it is ready it will grasp the silk button with it last prolegs and hang upside down. This is called hanging in “j.”

In 1939, mining engineer Oliver Bowles estimated 259,000 miles of stone walls have been built in New England. Damage from theft, strip-mining for commercial sale, and demolition for housing construction has left about 100,000 miles, according to the Stone Wall Initiative, https://stonewall.uconn.edu/# (from which most of this entry is gleaned). Re-building these iconic land forms causes archaeologic sites to be changed into modern architecture, resulting in the loss of cultural significance. A bit of saving grace is that many stone walls are described within property deeds, in which boundaries are memorialized by the wall’s locations…giving them monument status and a bit of protection from removal. Some folks realize the benefits of stone walls and have enacted state laws and municipal ordinances for their protection and considerations.
So, what about stone walls? How’d the stones get there? Where’d they all come from? Well, comets and asteroids containing ice formed from space dust and slammed into each other, eventually forming Earth. Ice turned to water thanks to the Sun and collected into a great ocean. Polar caps formed and glacial periods followed. Back-and-forth glacial movements along with erosion from winds and rains eroded Earth’s surface, dumping rocks everywhere. The glaciers were very generous with the New England area! The settlers needed someplace to set the rocks they cleared for their crops, so walls served to denote field boundaries and helped to contain livestock.
But another creation is offered by these structures…habitat!
The stone provides a surface upon which lichens will live. Lichens provide an inviting substrate for various mosses, ferns, and trees to root; black birch are especially fond of beginning their lives within a mossy world. These rock-loving plants provide the little bugs upon which many returning birds rely to recuperate from their migrations, and which help sustain other, over-wintering creatures: turkey and other birds, various amphibians…and the animals that eat them!
Cats, squirrels, and foxes use them as travel lanes, and the extra elevation helps them spot prey, or predators. Endangered Blanding’s turtles migrate to breeding sites along stone walls, where the leaf litter provides moisture and there’s more protection from predators. Chipmunks and white-footed mice are attracted by the protection, while mink, snakes, foxes, and owls await their emergence. Stone walls literally make our landscape come alive, creating a keystone habitat and the basis for a food chain.
Stone walls create their own ecosystems. Being attached to, and rising from, the soil and earth, summer’s heat and winter’s cold are tempered, easing the effects of temperature extremes on the many reptiles and amphibians that make their home within the walls protective stones. The base is cool and moist, the crevices like tiny caves; the top…warmer, drier, and more barren. One side might be woods, the other field. Many animals are attracted by the diverse habitat made by the redirection of winds, affording protection on the leeward side. Snow pack and rainwater drainage is heavier on the uphill slopes, causing soil run-off to be deposited there thus providing a rich growing medium for plants to thrive on one side, and not quite so much on the other side; Often there will be shade-loving plants and sun-loving plants on either side. These habitats create a diverse ecosystem throughout the length of the wall, strengthening the overall health of the surrounding landscape.
Kennebunk Savings Bank Helps Local Land Trust Project
July 11, 2019
Sanford/Springvale Mousam Way Land Trust is thrilled to announce the generous $10,000 donation from Kennebunk Savings Bank towards the Trust’s ongoing community-orientated effort: Sanford Community Garden at the Pence Ecology Center in The McKeon Environmental Reserve in Springvale. The Center and Garden, separate projects but growing together, will both be well served by this thoughtful gift.
Brad Paige, Kennebunk Savings President and CEO, explained the Bank’s Community Promise program, begun in 1994 by then Bank CEO Joel Stevens, who thought that a mutual institution should pay dividends to not only its investors, but also to its communities. The subsequent 25 years has seen the Bank donate $13 million to more than 1,200 organizations. And in this 25th year, a record $1 million will shared to area non-profits. Along with this, the Bank’s dedicated employees will have volunteered personal time at local non-profits, nearing the 10,000 hour mark in 2019.
As stated on the Bank’s Facebook page: “When we heard about the Sanford/Springvale Mousam Way Land Trust’s new community gardens and ecology center for environmental education, we knew we wanted to provide support for this amazing project. In addition to its educational focus, the center’s community gardens house 24 raised beds that will be used by local nonprofits and families to grow healthy, fresh food. The collaborative spirit of this project truly resonates with us and we’re excited to see the remainder of this project come to fruition!”
Mr. Paige stated that Kennebunk Savings Bank has been very successful in its communities over the years, helping to build many homes and businesses, so to help preserve land for future generations is the ethical and moral thing to do. Mousam Way Land Trust is grateful for the Bank’s forward thinking and their Community Promise program donation.
The Mousam Way Land Trust is pleased to be partnering with the local horticultural community’s farms during Springvale’s 5th Annual Farm Walk this summer, July 28. During your visit, via shuttle if you wish, you’ll be offered:

(As reported in Journal Tribune, June 27, 2019)
SPRINGVALE — The York County Chapter of the University of Maine Extension Service Master Gardener Volunteers, and the Maine Master Gardener Development Fund has announced the awarding of a $500 grant to the Sanford Community Gardens.
The Maine Master Gardener Development Fund supports the establishment or expansion of horticulture-based educational projects in communities across Maine.
Located at the Pence Community Ecology Center in the McKeon Environmental Reserve on Blanchard Road in Springvale, Sanford Community Gardens has begun its first year of providing raised bed plots where folks who lack access to suitable land can grow their own organic vegetables, flowers, and herbs.
More information can be found here: mousamwaylandtrust.org/2019/03/07/sanford-community-garden/.
Local Master Gardener Project Coordinators and Mousam Way Land Trust Directors form the Community Garden Advisory Committee which oversees the project. Master Gardener volunteers assist the raised bed gardeners with all aspects of gardening: initial soil testing interpretations, compact and season-extending gardening methods, organic weed, pest, and disease controls, to safe harvesting techniques and winter bed preparations.
