Restoration in Progress

During the past three decades, public interest in prairie restoration has grown significantly. The motivations to participate in ecological restorations vary; for me, working to restore a piece of the prairie, both as a volunteer steward and as an individual, provides a source of spiritual renewal. Not only am I spiritually, but also physically renewed in the process of reclaiming the land and building a piece of the prairie. Sweat equity is a rejuvenating tonic!

An ecologically sound and thriving prairie landscape is built using a complex and diverse plant community comprised of many different species of grasses and forbs. In fact, restoration ecologist, Roger C. Anderson has identified the four components required to recreate an ecologically sound prairie.

Four ingredients necessary for ecological restoration
to be successful include: (1) a vision of what the ecosystem
being restored should be like when the restoration is finished,
(2) an understanding of the ecological processes needed to
restore and maintain the ecosystem, (3) knowledge of the
specific restoration skills and management practices that
are needed, and (4) public support for goals of ecological
restoration and confidence in the principles that form the
scientific basis for restoration. Research can contribute to all
of these components (Roger C. Anderson).

With these four elements in mind, one must also consider that “…each restoration site is unique in terms of its original ecological attributes, kinds, extent, duration and  intensity of human disturbance, and management activities, each restoration solution must be unique” ( Stephen Glass). After thorough ecological assessment of the site, the first physical restoration step requires the removal of invasive plant species from the site. Stephen B. Glass, a restoration ecologist, believes a restoration plan that “…ignores the fundamental causes of the pest species invasion and just treats the symptoms,” will result in a continually frustrating battle between the restorer and the invasive species. He suggests that when one tackles the underlying cause for the invasive species prevalence in a habitat by treating it like a “repair job.” Look at “…what you know, what you don’t know, and what you will need to learn to solve the [restoration] problem” (Glass). Specifically, look for an “… altered hydrology, or soil disturbance, or increased soil fertility. If the underlying cause is not dealt with, then continued frustration and [re-occurrence of invasive species] will be likely” (Glass).

In a previous post, Invasives Begone, I outlined the steps for land preparation in the restoration process. Therefore, once the invasive plants have been dealt with, the seedbed prepared, the next step is to reconstruct the plant community. Native plants are given the greatest opportunity to thrive if local ecotype seeds or plugs are used to reestablish the health and biodiversity of an ecosystem. After the seeds or plugs have been planted, the rest of the first growing season is spent watering and weeding the seedbeds. The second season requires spring removal of dead plant material and weeding. The first blooms are likely to appear during growing season two or three.

Below, I have linked two videos that exemplify a restoration in progress. The prairie restoration demonstration video produced during the 2010 Chicago Lawn and Garden show does a great job of illustrating the steps of the restoration process.

The second video also does a nice job of showing the annual progression of a Minnesota prairie restoration garden.
