summary
 |
The proposed
project seeks to restore the stream channel, riparian corridor, and floodplain
wetlands on a 21-acre property along Burd Run in Shippensburg, Pennsylvania.
The property, now publicly owned as a Shippensburg Township Park, is severely
degraded by nonpoint sources of excessive sediments and nutrients. Artificial
channel straightening and removal of riparian trees and shrubs have destabilized
the stream, resulting in approximately 1200 linear feet of accelerated bank
failure. In addition, elevated concentrations of nitrogen and phosphorus
are present in the stream as a result of upstream agriculture taking place
on shallow soils overlying steeply dipping and cavernous limestones. Floodplain
wetlands located on the site have been ditched and drained, greatly reducing
their ability to mitigate nutrient loads. |
The proposed restoration
project would reverse these actions through the application of best management
practices (BMPs) toward the following integrated objectives:
1. Restoring
the Burd Run stream channel
Natural stream design concepts and erosion control BMPs will be used to reestablish
a stable, meandering stream channel. This will result in the following benefits
to the stream system:
- The longer,
meandering channel will have a flatter slope and less erosive energy, reducing
the significant non-point source of sediments presently generated by accelerated
channel erosion.
- The restored
channel will increase aquatic habitat by 8500 ft2.
- The diversity
of habitats supporting aquatic and riparian plants, invertebrates, fish, birds,
mammals, and other animals will be enhanced by recreating riffles, glides,
and pools flowing around point bars and cutbanks.
- The present
threat of channel erosion into a sewer line less than 10 feet north of the
present stream will be eliminated by restoring the stream channel to its historic
location.
2. Enhancing
riparian vegetation
An 80 foot riparian buffer corridor--now virtually non-existent--will be restored
by planting native tree and shrub species. This will result in the following
benefits to the stream system and property:
- The roots of
riparian plants will provide additional structural stability to the streambanks,
further reducing bank erosion and associated nonpoint sources of sediments.
- The selected
plants will provide a canopy over the stream, shading water and reducing stream
temperatures. This will facilitate greater dissolved oxygen and healthier
aquatic life.
- The selected
species for the riparian corridor will enhance wildlife habitat and site aesthetics.
3. Restoring
floodplain wetland vitality and function
Limestone springs exist in several locations at the site and feed wetlands both
north and south of the stream. Spring water represents a significant nonpoint
source of pollutants, consistently carrying high nutrient loads and contributing
up to 20% of stream base flow. This project will eliminate artificial wetland
drainage and restore natural wetland hydrology, providing the following benefits:
- Greater retention
time of water in the wetlands will facilitate nutrient reduction through vegetative
uptake and denitrification. Recent studies show that similar restored wetlands
can reduce nitrate concentrations by 68% and phosphorus concentrations by
43% (Woltemade 1999, 2000, Mitsch and Montgomery 1998).
- Restored hydrology
will allow deeper water to pool within the wetlands, increasing the diversity
of wetland habitats for both plants and animals while also improving site
aesthetics.
- The restored
wetlands and riparian buffer will complement each other in reducing nonpoint
sources of nutrients. The Burd Run project design will be similar to an Illinois
restoration project that combines restored wetlands with a healthy riparian
zone to provide substantial water quality benefits (Woltemade 1999, 2000,
Kovacic 1998).
4. Enhancing
education and community outreach
Educational programs will be developed for the general public, school groups,
and university students. Hundreds of park users will learn from a network of
interpretive nature trails that will guide visitors to experience each of the
riparian environments and emphasize the importance of watershed protection.
Public education will also target people not already involved in community environmental
issues through press releases, lectures, a project web site, and two educational
videos. Shippensburg University, the Rowland School, and Shippensburg public
schools, all located less than five miles from the project site, will develop
regular educational field trips. This project builds on over three years of
data collection and stream restoration design studies conducted at Shippensburg
University (SU). The project will utilize an extensive watershed database and
water quality monitoring program conducted at the Burd Run Interdisciplinary Watershed Research Laboratory, a National Science
Foundation funded effort at SU.

project will combine the capabilities of the Cumberland County Conservation
District with over 20 community and agency partners, including:
