How the Program Works

  1. Advice provided to landowner through “house calls” made by Habitat Advisors.
  2. Habitat Advisors are trained in a variety of conservation practices for suburban landscapes.
  3. House Calls are made by Habitat Advisors who come by appointment to your home after landowner submits an online application.
  4. The house call includes a review of the landowner’s goals for their landscape, an interactive walk-through of their space and recommendations in a written report.
  5. The written report provides a menu of recommendations on how to improve the landscape as bird and butterfly habitat.
  6. Program Pay Off – when a certain level of conservation is achieved, the owner is awarded one of three levels of certification – silver, gold or platinum.
  7. The Real Pay Off – regular nature encounters with birds, butterflies, perhaps even Monarchs with an attractive native landscape that produces less storm runoff, lower water bills and more.
  8. Homeowner Cost - 50% off regular program fee (currently $50). The minimum fee is $25. Upon reaching a particular level of certification the landowner may choose to purchase a program yard sign. Current cost of the sign is $20.
  9. Non-Residential Properties – program is not restricted to residential properties. The fee schedule may vary for larger institutional/commercial properties.

Milkweeds for Monarchs

Monarchs play an important role in our ecosystem as they make their annual migration from Canada to Mexico and back. They are pollinators. These migrations are now threatened as monarch populations have declined 90 percent over the past two decades. Much of their habitat has been destroyed through the misuse of herbicides and insecticides. Female monarchs depend on milkweed to lay their eggs and feed their caterpillar larvae, so without milkweed we would have no monarch butterflies.

We can help restore their habitat with plantings in our yards and gardens or at school or work. All it takes is to plant a square yard of a milkweed mix (hardy non-invasive weeds). By planting milkweeds and a variety of nectar plants, you can help the monarch butterfly as well as other pollinators

Monarch Butterflies need our help

Well-known for their incredible annual migrations between Canada and Mexico, monarch butterflies are vital participants in pollination of the plants in our local eco-systems. Given the great numbers of Monarchs (up to 100 million) that gather to migrate each fall, it is hard to imagine them facing any threat of extinction. But Monarchs and their amazing annual migration are seriously threatened by human activities, in both their summer and overwintering sites. Their populations have declined 90 percent over the last twenty years. Many of the threatening activities are the cause of the destruction of good Monarch habitats. In the north (the United States and Canada), Monarchs face direct habitat destruction caused by humans. New roads, housing developments, and agricultural expansion - all transform a natural landscape in ways that make it impossible for Monarchs to live there. Monarchs in the north also face more subtle habitat destruction in the loss of their host plants. Milkweed, the plant larvae (caterpillars) feed on exclusively, is considered a noxious weed by some people and is often destroyed. In some areas across North America, milkweed plants are also being severely damaged by ozone. Both milkweed and plants that adult butterflies feed on are also vulnerable to the herbicides used by many landscapers, farmers and gardeners. Adult Monarchs themselves are being killed outright by many pesticides. Help bring back the Monarchs! To offset the loss of milkweeds and nectar sources we need to create, conserve, and protect milkweed/monarch habitats. We need you to help us and help monarchs by creating "Monarch Waystations" (monarch habitats) in home gardens, at schools, businesses, parks, zoos, nature centers, along roadsides, and on other unused plots of land. Without a major effort to restore milkweeds to as many locations as possible, the monarch population is certain to continue to decline to extremely low levels. The City of Clayton Parks Department maintains MonarchWaystations in Shaw, Oak Knoll, Wydown Parks, along the GRG Trail and at The Center of Clayton. Plans for more Monarch Waystations in other parks are in the works. The City of St Louis has launched a citywide initiative, The STL Milkweeds for Monarchs.

Sustainable alternatives to supplement fossil fuels we use to heat our homes.

Before the 20th century, 90 percent of Americans burned wood to heat their homes. As fossil fuel use rose, the percentage of Americans using wood for fuel dropped, falling as low as one percent by 1970. Then during the energy crises of the 1970s, interest in wood heating resurfaced as a renewable energy alternative.

Newer on the scene are pellet fuel appliances, which burn small pellets that look like rabbit feed and measure 3/8 to 1 inch in length. Pellets are made from compacted sawdust, wood chips, bark, agricultural crop waste, waste paper, and other organic materials. Some pellet fuel appliances can burn a wide variety of biomass fuels, including nutshells, corn kernels, small wood chips, barley, beet pulp, sunflowers, dried cherry pits, and soybeans

Today you can choose from a new generation of wood- and pellet-burning appliances that are cleaner burning, more efficient, and powerful enough to heat many average-sized, modern homes. It's also important to use a properly sized appliance for the space to be heated. When an appliance is too big, residents tend to burn fires at a low smolder to avoid overheating, which wastes fuel and is one of the biggest causes of air pollution. A reputable dealer should talk with you about size requirements, but a good rule-of-thumb is that a stove rated at 60,000 British Thermal Units (Btu) can heat a 2,000 square foot home, while a stove rated at 42,000 Btu can heat a 1,300 square foot space.

High-efficiency Fireplaces and Fireplace Inserts

Designed more for show, traditional open masonry fireplaces should not be considered heating devices. Traditional fireplaces draw in as much as 300 cubic feet per minute of heated room air for combustion, then send it straight up the chimney. Fireplaces also produce significant air pollution. Although some fireplace designs seek to address these issues with dedicated air supplies, glass doors, and heat recovery systems, fireplaces are still energy losers. When burning a fire, you should turn your heat down or off and open a window near the fireplace.

Only high-efficiency fireplace inserts have proven effective in increasing the heating efficiency of older fireplaces. Essentially, the inserts function like woodstoves, fitting into the masonry fireplace or on its hearth, and use the existing chimney. You must install a flue collar that continues from the insert to the top of the chimney. A well-fitted fireplace insert can function nearly as efficiently as a woodstove.

Catalytic Wood Stoves, Advanced Combustion Woodstoves, and Centralized Wood-Burning Boilers

Wood stoves are the most common appliance for burning wood. New catalytic stoves and inserts have advertised efficiencies of 70–80 percent.

Advanced combustion woodstoves provide a lot of heat but only work efficiently when the fire burns at full throttle. Also known as secondary burn stoves, they can reach temperatures of 1100°F—hot enough to burn combustible gases.

These stoves have several components that help them burn combustible gases, as well as particulates, before they can exit the chimney. Components include a metal channel that heats secondary air and feeds it into the stove above the fire. This heated oxygen helps burn the volatile gases above the flames without slowing down combustion. While many older stoves only have an air source below the wood, the secondary air source in advanced combustion stoves offers oxygen to the volatile gases escaping above the fire. With enough oxygen, the heated gases burn as well. In addition, the firebox is insulated, which reflects heat back to it, ensuring that the turbulent gases stay hot enough to burn. New advanced combustion stoves have advertised efficiencies of 60 to 72 percent.

Another benefit is that the secondary channels funnel hot air toward the glass doors, keeping them clean for viewing the fire. They can also be slightly less expensive than conventional woodstoves fitted with catalytic combustors. Like wood stoves, centralized wood-burning boilers have been improved over the last several years. Modern, centralized wood heaters use wood gasification technology that burns both the wood fuel and the associated combustible gases, rendering them efficient up to 80 percent. In addition, systems are available that can switch to oil or gas if the fire goes out.
