SEMINAR THEME - "A Matter of Balance: Approaches to Soil Health and Water Quality" 

Soil health and water quality are intrinsically linked, and management of these resources faces great challenges due to emerging ecological, economic and climatic pressures. It is important, now more than ever, to support soil’s natural ability to filter water that moves across and through a landscape. Establishing conservation practices that support a balanced relationship between soil health and water quality is a proven best management practice in agricultural production. Management choices that fail to recognize and protect the physical, chemical, and biological attributes of healthy soil have the potential to jeopardize water quality and ecological productivity.

Soil not only holds environmental and agricultural importance; it is vital to ensuring the growth of a healthy economy.1 In this Seminar, we will examine emerging practices to mitigate the vulnerability of our soil and water resources to changing climatic, market and land use conditions in the context of our global challenge to meet growing demand.

MACKINAC ISLAND FALL TOUR
Held Saturday
, October 5, 2013

The Michigan Chapter Soil and Water Conservation Society held their Fall Touring event on Mackinac Island on Saturday, October 5. The event included three tours. The Mackinac Island Geology and Natural Features Tour was held in the morning, and the Composting Site/Wastewater Treatment Facility Tour and the Grand Hotel Green Initiatives Tour were held in the afternoon.

We had a buffet lunch at the Grand Hotel at noon. The legendary Grand Luncheon Buffet is one of the highlights of the Grand Hotel experience.

Here is information about, and photos from, the tours.

Composting Site/Wastewater Treatment Facility Tour

We first biked to the Island’s Recycling and Solid Waste Composting Operation. This site is vitally important, since every dumpster of trash shipped to a landfill on the mainland costs $1,100. Sorting materials that can be recycled or composted is the job of every resident and business. Mackinac Island has the only approved municipal solid waste composting operation in the state. More.


Empty bottles and other recyclable plastics are brought in from throughout the island and converted to bales to be shipped to a processor off the island.



The value of the recycled materials nearly pays for the operation.


Materials that can be composted are shredded, mixed and added to the composting operation that includes several large bins and a loader to move the material.

We then biked to the Waste Water Treatment Plant (WWTP).  (Location map) Upgrades have been made recently to ensure long-term compliance with its discharge limits. The upgrades were designed to take into account the large fluctuation in flows and loads observed at the plant as a result of seasonal tourism on the island. More.

The project included new influent flow metering, a new summer headworks facility, a new winter mechanical screen, and many other upgrades. Mackinac Island received low interest loans and American Recovery and Reinvestment Act grants to cover the costs of the project through the U. S. Department of Agriculture, Rural Development agency. More.

Grand Hotel “Green Initiatives” Tour

In 2009, the Grand Hotel was awarded the Green Lodging Michigan (GLM) “Partner” certification from the Michigan Department of Energy, Labor & Economic Growth (DELEG) for its comprehensive efforts to protect the environment. The award recognizes the fact that behind the scenes of the Grand Hotel and Mackinac Island are state-of-the-art programs to seek out and implement the latest technology to protect the island’s pristine environment.

The Grand Hotel viewed from the gardens below.

These efforts include:

  • The water-based air conditioning system Grand Hotel designed and installed in its most classic rooms
  • An island program that composts all biodegradable waste on the island
  • Changing over to energy-efficient light bulbs throughout the hotel
  • Offering guests an option with regards to the frequency of linen exchange
  • Limiting the amount of paper waste by centralizing some information instead of delivering to all guestrooms
  • A specially designed composting system that produces all the compost Grand Hotel uses in its signature flower beds.

It takes about a year and a half to use a compost pile, and the hotel has three piles going at any one time. Work on the piles and on the hotel’s gardens starts in the middle of April each year and goes through the middle of November. Each fall the hotel plants a ton of flower bulbs, including 25,000 tulips and 15,000 daffodils.

For the Grand Hotel and Mackinac Island, all of these initiatives are part of a continuing effort to provide modern conveniences to visitors while protecting the environment and maintaining the 19th Century charm for which both are known around the world.For the Grand Hotel and Mackinac Island, all of these initiatives are part of a continuing effort to provide modern conveniences to visitors while protecting the environment and maintaining the 19th Century charm for which both are known around the world.

Mackinac Island Geology and Natural History Tour

Jeff Dykehouse, Mackinac Island State Park Naturalist from the Michigan Department of Natural Resources, guided this walking tour.

Jeff took the group to the highest point on the Island, which is the site of Fort Holmes, approximately 310 feet above the surface of Lake Huron.

The site affords visitors an extraordinary view of Round Island, the Straits of Mackinac and the Mackinac Bridge.

During the tour Jeff talked about the Island’s wildlife and the impacts of human activity and invasive species on the wildlife. He also discussed the geological history of the Island, and answered questions about Mackinac Island State Park. (More)

    WORKSHOP PROGRAM

    Pointing at Non-point:
    Finding the Source at the Watershed Scale

    This afternoon technical session explored the world of watershed sediment fingerprinting research and the implications this has on how we manage the land. Participants learned about research techniques that attempt to track where erosion is really occurring in a watershed. Presentations included information about a recent study that has been conducted and is on-going in the Macatawa Watershed, a small watershed in southwest Michigan that drains directly to Lake Michigan. Participants learned how this type of research can be used by land managers and resource professionals to more effectively target conservation on the ground. We discussed how this type of research impacts how we view non-point source pollution. This research raises the question: Does the ability to track non-point source pollution make it a point source?

A MATTER OF BALANCE: ENERGY, WATER AND WORKING LANDS

Energy and water are inextricably linked, according to a Great Lakes Commission Issue Brief. Called the Energy/Water Nexus, the brief states that it takes water to produce energy and it takes energy to make water available. How does this relate to Working Lands, such as Farmland and Forest Land? It takes energy to get products from working lands, and working lands produce energy in foods and fuels. The production of biofuels, such as corn-based ethanol, uses vast amounts of water. When ethanol is produced from corn that is irrigated, it can use nearly 1,000 gallons of water per gallon of fuel. It takes energy to provide this water, and energy costs money. So any practice that produces energy or reduces energy use, potentially reduces costs. This Seminar looked at the relationships of energy, water and working lands, how each impacts the others and how both conservation and wise use helps to sustain all three. For more information on the Energy/Water Nexus, see the Great Lakes Commission Issue Brief.

    East Lansing, Michigan

    Simply put, ecosystem services are the multitude of benefits provided by the environment. The idea of ecosystem services is nothing new. What is new is the way that ecosystem services are being considered by conservation organizations and natural resource managers. An ecosystem approach challenges us to consider all aspects of a proposed action, not just the primary purpose. For example, a grassed waterway helps to safely convey excess water off a field to reduce erosion, but how does this practice affect wildlife? Air quality? Carbon sequestration? Join us as we explore the world of ecosystem services and how to incorporate these ideas into the ways we manage our natural resources and environment.

    A Matter of Balance: Soil and Policy/Economics/Climate Change/Public Demand

    The purpose of this Seminar was to discuss the relationships between the prospect of sustainable soil productivity for future generations versus the way we have been and are managing the soil, the demands we put on our soils and the expectations we have for our soils.  We looked at a brief soil history of western civilizations; the current state of our soils and our progress in conservation and management; why is soil important; the impact of climate change; and economic and policy issues that drive our decisions in soil use, management and conservation.  Attendees should have gained a better understanding of the need for conservation, enhanced respect for the importance of soil and an understanding of the impact of human decisions on soil sustainability.

    This seminar was intended as a professional development program for SWCS members and others who work in the field of soil conservation and management, but was also open to land users, students and anyone else interested in our soils.
