Going wild: mitigation transforms campus

Fri, Dec 12, 2008

Calvin students Brian Schaap and Linda Van Andel see the benefit of their summer research every time they step foot on campus.

Tangible evidence

The seniorstudents spent this past summer on a mitigation project, which involved native plant restoration and re-creation of forest habitat in various locations on campus. 鈥淚 feel like our research project had a real positive impact on campus,鈥 said Van Andel. 鈥淚 think it was great that we could do this project, and we were learning things through it. It was a tangible accomplishment鈥攐ur work is still out there.鈥

In fact, their work is evident in three places around鈥攏ear the Burton Street entrance, north of Ravenswood guest house and around van Reken Hall鈥攚here unused or lightly used portions of lawn were turned into sustainable forest areas or landscaped with native plants.

Salvaging the woodlot

The project was supported by a mitigation fund that was set up by the college to help offset the loss of nearly one-half of the woodlot just north of the new Spoelhof Fieldhouse Complex.

When the first plans for the came out, they involved eliminating the entire woods,鈥 said David Warners, the Calvin biology professor who oversaw the mitigation project. 鈥淲hen [fellow biology professor] Randy Van Dragt and I questioned whether we could save some of the woodlot, people were very open to considering alternatives.

Hawk habitat

The woodlot in question is a really, really nice woods. There are a number of rare species and unusual plants; there is a very nice stand of trees鈥攕ome 100 to 200 years old鈥攁nd a Cooper鈥檚 Hawk鈥檚 nest in one of them.

A compromise with the facility planning committee was reached resulting in some of the woodlot being saved and a fund was created to help mitigate the amount of the forest that was lost. That鈥檚 where the work began for Schaap and Van Andel.

Re-creating forest habitat

The students spent the summer re-creating forest habitat and initiating a scientific study to measure the most effective methods for doing so successfully. Six areas were divided into quadrants in which altered depths of leaf mulch were spread for weed suppression and moisture retention. Tree and plant arrangements were also varied. (Many of the plants were rescued from the athletic complex site before the demolition and from a local cemetery that was clearing land). The students hope that their initial research will allow future students to determine the best practice for introducing forest ecosystems into previously managed landscapes.

Up to this point most restoration wisdom has been accumulated by word of mouth,鈥 said Warners. 鈥淭he scientific rigor has not been as present as it should be. Over time we will be able to research this area and hope to contribute solidly to the conversation about restoration ecology.鈥

From manicured to "scrubby"

Schaap, who is co-chair of the student-run Environmental Stewardship Coalition, also hopes that the project will help to educate non-researchers about restoration ecology.

At first, some people were opposed to our project,鈥 he said. 鈥淭hey were worried that it wouldn鈥檛 look good. 听We were taking these nicely manicured lawn areas and turning them into a scrubby forest.鈥

Cost of landscaping

Surprisingly, aesthetics is a bigger hurdle than the cost, according to Warners. 鈥淚 hear comments like, 鈥業t looks so messy,鈥 or 鈥業 like forests with big trees.鈥欌 Peoples鈥 perception of beauty is a one-species鈥擪entucky Blue Grass鈥攏eatly mowed lawn. What they don鈥檛 understand is the cost of maintaining that type of landscaping. If they factored in the cost of herbicides, pesticides and fungicides and the fossil fuel used for mowing and water, the appeal would start to erode.鈥

At least that is the hope. 鈥淢y perception on what is beautiful landscaping has completely changed,鈥 said Van Andel. 鈥淧eople think that a lawn is so wonderful and natural, but that isn鈥檛 restorative at all.鈥

Serving creation

What I鈥檝e learned in that last four years is that redemption is about all of creation, not just humans,鈥 added Schapp. 鈥淥ur job as Christians is to participate in the work of bringing about shalom鈥攔estoring right relationships. We are to imitate God as servants, but beyond serving other people, it鈥檚 also about serving creation. Projects like this are ways we can serve creation.鈥

While the research is ongoing, Warners also hopes to find other spots on campus that can be reclaimed as forested areas. 鈥淚鈥檓 pleased with the effort Calvin has demonstrated,鈥 he said. 鈥淏ut I don鈥檛 want people to think that we know how to make forests now, so we can just tear them down and re-create a new one. Preservation should always be the first priority.鈥

Warners, though, also recognizes the necessity for some unforested area on the campus. 听鈥淚 don鈥檛 want to convert every square inch of lawn into forest at Calvin,鈥 he said. 鈥淚鈥檓 hopeful we can identify places on campus that very few, if any, people use鈥攖o convert from lawn into more sustainable forest.鈥
