Restoration Education

April 1, 2019

Flowing around the southern perimeter of the Robbinsville Middle and High School campuses, Sweetwater Creek is an ideal place for outdoor science learning, and Mainspring’s youth education program is taking advantage.

Through a partnership with Graham Revitalization Economic Action Team (GREAT) and Robbinsville High School, Mainspring is improving the quality of the streambank while teaching kids about non-native invasive plants and the harmful effect they have on aquatic habitat, birds and native plants.

“Students generally understand the idea that some species are invasive in certain areas,” says Ben Davis, Robbinsville High School science teacher. “But when they get out on the creek bank and see both the sheer amount of invasive plants and the work it takes to restore the environment to its natural state, it really drives the idea home that we should try to control our invasive species as much as possible.”

Rivercane, a native bamboo important for thousands of years to indigenous people, was growing along Sweetwater Creek, but was being invaded by Chinese privet, a very aggressive non-native plant. Since 2016, students have been pulling up Chinese privet by hand and with a lever-like tool called the Weed Wrench and replacing it with native trees and shrubs. Davis says the continuity of the project is one of the benefits. “Since we’ve been doing this for several semesters and with all science classes, some kids have followed the project for several years and can see the progress we are making.”

The restoration project includes sampling fish and catching birds to monitor their populations in and near the creek. In 2019, Mainspring will add instruction on traditional Cherokee basket making using rivercane to the curriculum.

“It makes it easier for me as a teacher to discuss ecosystems and native species when we can give examples of plants right here on campus,” Davis said. “It’s fun to observe which of my students will really throw themselves into the physical labor, because it’s not always the ones I expect.”

Funding for this program comes from the Cherokee Preservation Foundation through its Revitalization of Traditional Cherokee Artisan Resources Program.

On the Move

Thousands of small, shiny fish are making their way from rivers to smaller creeks this time of year, and biologists are determined to find out why.

In order to gain a better understanding of what triggers this annual migration, Mainspring Conservation Trust is collaborating with Tennessee Valley Authority (TVA) on a project to study these minnows. Mainspring’s biologists are also analyzing what creeks or habitats the fish are searching for and how long they remain in the creeks after then find them – before swimming back to the rivers.

Shiners and minnows can be found almost anywhere, but many of the minnows in western North Carolina prefer free-flowing waters instead of the standing water found in lakes. The type of free-flowing water matters too; some species of shiners prefer small creeks while others prefer larger rivers. However, in the fall, there is a mass migration of the river shiners into the smaller creeks. The federally Threatened spotfin chub is one of the species that have been documented to move from larger rivers into small creeks each fall.

In creeks where shiners have been observed before, Mainspring’s biologists are currently surveying every week to determine when this migration starts. Although it varies slightly from year to year, the week of October 8^th marked the first indication that the migration had started for 2018, when Whitetail shiners, found mostly in the river, began to outnumber Warpaint shiners, a creek dweller.

Why are shiners important? Anglers are well aware these shiners make up a large part of the diet of our gamefish such as bass, catfish, and walleye. Lots of shiners mean more biodiversity and more and larger fish to catch for all anglers – both locals and tourists.

What can you do to help with their migration? Fish move to small streams for reasons we do not understand, but rarely does any species do something without purpose. Small streams are often the most neglected, and, while they are always ecologically important, they are even more so during certain times of the year. Shading your stream and providing alternative watering sources for livestock are just two ways to take care of what you may consider an insignificant little branch. That’s important because that branch may, in part, play a role in the life of the fish that you or your loved one may catch on the river next summer, or in the life of the one that got away.
