Helping Native Brook Trout by Restoring a Stream

Many of New Jersey’s streams have been manipulated by being impounded with dams or weirs, or otherwise redirected over time – decreasing their ecological habitat diversity and blocking fish passage for native brook trout and other species. Restoring these streams to a more natural state can greatly benefit wildlife. 

The Land Conservancy of New Jersey, along with assistance from Conserve Wildlife Foundation, Natural Resources Conservation Service, and Urbani Fisheries, worked on a stream restoration project on a highly modified part of stream flowing through the West Brook Preserve in West Milford this summer. This vital 170-acre preserve holds the headwaters of the West Brook, one of the primary sources of water for the Wanaque Reservoir, which provides drinking water for two million New Jerseyans. 

It appears that sometime in the 1950s, part of the West Brook was taken out of the original stream channel and redirected to a channelized ditch that ran alongside it. There were also several culverts installed in the stream (including one that was the size of a small grain silo) which restricted flow and acted as a blockade to fish passage. In addition, one of the unnamed tributaries leading to the mainstream channel had a pond where water was being held back by a weir, resulting in elevated water temperatures. The original channel and tributaries also needed an enhancement of a thalweg, the line of lowest elevation that the stream follows as well as the addition of pools, riffles and runs.

A healthy stream should have an established thalweg – a connected floodplain – as well as pools, riffles, and runs. All of these features are important in the function of the stream.  For example, pools provide areas for various aquatic species to seek refuge, while riffles aid in the reoxygenation of the water.

The ultimate goals of the West Brook project included restoring the native fish habitat, improving the overall water quality, and rejuvenating the macroinvertebrate population. 

The work done to accomplish this included:

  • Restoring the river back to the original stream channel. 
  • Enhancing features along the whole length of the stream.
  • Creating wetland pools out of the old ditch and within the riparian zone. 
  • Removing five culverts and the small weir. 

After the restoration, it appeared some of the site is now suitable for native brook trout, and the project has greatly improved habitat diversity in a stream that flows into a Category One trout production stream. New Jersey Fish & Wildlife and The Land Conservancy will continue to monitor the project.

Anyone already planning their fishing trip to their favorite stream this spring? Sunshine and cool refreshing streams will be here before you know it!

 

Streams and rivers are an essential part of our ecosystem, providing food, shelter and breeding grounds for hundreds of New Jersey native wildlife, as well as providing water for human use. These wildlife include, macro-invertebrates, reptiles, birds and fish such as the Eastern brook trout.  The Eastern brook trout is valued for its beauty, sport-fish qualities and is an indicator of the health of our watershed. It is also the only native trout species in New Jersey, but is unfortunately threatened by urbanization and dense road networks which contribute to sedimentation, warmer waters and pollution.

 

This past year, CWF biologists along with our partner agency USDA’s Natural Resources Conservation Service (NRCS) have been working in conjunction with New Jersey Audubon Society to improve stream habitat throughout about 5,000 feet of the Musconetcong River. The Musconetcong River currently supports brown trout, and through restoration of the watershed it has the ability to support Eastern brook trout as well.

 

In order to restore the reach of the Musconetcong River, pool and riffle sequences were created and deep pools and point bars were established in the stream channel. These restoration techniques provide spawning habitat for trout, as well as benefit the organisms they depend on for food. Furthermore, the restoration of appropriate channel morphology helps to create a healthy riparian zone through the enhancement of flood plain connectivity.

 

CWF and USDA-NRCS continue to work with farmers and other landowners to plant stream-side shrubs and trees, fence livestock out of waterways, remove dams and use less pesticides in order to promote healthy watersheds. These practices will not only help prevent pollutants from reaching our waterways, but they will help maintain functioning ecosystems that will digest and filter pathogens and sediment. This collective effort by local land managers and landowners will enable us to protect human health, assure clean water and preserve our quality of life for generations to come.

Greene, the Honorable Christine Todd Whitman, Pat Hamilton, MacKenzie Hall, Tanya Oznowich, and Diane Nickerson.

 

Our Tenth Annual Women & Wildlife Awards, held at Duke Farms, recognized three women – MacKenzie Hall, Pat Hamilton, and Tanya Oznowich – for their leadership in protecting wildlife in New Jersey. The Honorable Christine Todd Whitman served as the keynote speaker.

 

The Women & Wildlife Awards celebrated Conserve Wildlife Foundation’s past decade of honoring women for their success in protecting, managing, restoring, and raising awareness for the Garden State’s endangered and imperiled wildlife species.

 

“The inspiring leadership of MacKenzie Hall, Pat Hamilton, and Tanya Oznowich not only benefits New Jersey’s wildlife and the countless people who care strongly for our outdoors – it provides successful role models for the next generation of girls in scientific fields that have for too long held a glass ceiling for young women,” said CWF Executive Director David Wheeler. “Their unparalleled dedication and hard work – like that of the Women & Wildlife honorees over the past decade – has helped make New Jersey a national leader in wildlife conservation.”

 

The three honorees were recognized individually with awards in Inspiration, Leadership, and Education:

MacKenzie Hall, a powerful force behind the conservation of wildlife in New Jersey, who began working as a wildlife biologist for Conserve Wildlife Foundation in 2004 before joining the Endangered and Nongame Species Program in 2014, is the recipient of the Women & Wildlife Inspiration Award. She has been involved in a number of projects spanning bat colonies, migrating amphibians, and grassland birds.

In her work to implement conservation programs such as the Natural Resources Conservation Service’s Wildlife Habitat Incentive Program, Ms. Hall’s keen understanding of the process and positive attitude turned many farmers and landowners into dedicated environmental stewards. What may be most remarkable about Ms. Hall is her ability to motivate the public and inspire non-scientists of all ages to become passionate conservationists.

 

Women & Wildlife Leadership Award Winner Pat Hamilton has worked for the New Jersey Division of Fish and Wildlife Bureau of Freshwater Fisheries since 1980. She is considered to be the champion for Eastern brook trout, the state’s only native salmonid, and a species once extirpated from over 50% of its historical habitat due to human impacts.

Ms. Hamilton is one of three fisheries biologists in New Jersey endeavoring to strengthen the state regulations to further conserve native brook trout streams. Thanks to her efforts, more than 200 northern New Jersey streams have been designated as Trout Production Streams, which afford the streams higher levels of state protection.

 

The recipient of the Women & Wildlife Education Award is Tanya Oznowich, Environmental Education Supervisor of the New Jersey Department of Environmental Protection, who has championed environmental education for over three decades.

Schools across New Jersey are incorporating environmental education into their curriculum, a new movement inspired by a growing awareness of environmental issues and our shared role in understanding and resolving them. To a large degree, this growing prominence is thanks to Tanya Oznowich. She has been engaging the public in natural resources since 1979. Since beginning her tenure with the NJDEP in 1988, she has dedicated herself to integrating environmental science into New Jersey’s classrooms, from kindergarten to college.

 

The Tenth Annual Women & Wildlife Awards, held on Wednesday, October 28 at Duke Farms in Hillsborough, New Jersey, included a presentation of the awards to the recipients, hors d’oeuvres, cash bar and a silent auction.

Fisheries Biologist Honored for her Contribution to Wildlife Conservation

by Lindsay McNamara, Communications Manager

Pat Hamilton Leadership Award Winner

Pat Hamilton Leadership Award Winner

Pat Hamilton has worked for the New Jersey Division of Fish and Wildlife Bureau of Freshwater Fisheries since 1980, most recently as the Principal Fisheries Biologist. Ms. Hamilton has become a leader in managing and conserving coldwater fisheries throughout the state. She is considered to be the champion for Eastern brook trout, the state’s only native salmonid, and a species once extirpated from over 50% of its historical habitat due to human impacts.

 

For her Master’s Thesis “Wild Brook Trout Genetics,” she examined the genetic diversity of Eastern brook trout populations in streams throughout the Raritan and Passaic watersheds. In the first study of its kind for the state, Ms. Hamilton determined that the trout present today are part of a lineage dating back to when the last glacier receded from New Jersey – some 16K-18K years ago! Since this landmark study, she has worked to restore and protect not only this ancient fish, but also the pristine habitat on which it depends.

 

Currently, Ms. Hamilton is one of three fisheries biologists in New Jersey endeavoring to strengthen the state regulations to further conserve native brook trout streams. Thanks to her efforts, more than 200 northern New Jersey streams have been designated as Trout Production Streams, which afford the streams higher levels of state protection.

 

Join us to honor Pat and the two other 2015 Women & Wildlife Award Winners on Wednesday, October 28 beginning at 6pm. Purchase events tickets and find more information.

We asked Pat a few questions about what working in wildlife conservation means to her:

 

Do you have a New Jersey wildlife species that you like best? Why?

When I was 12 years old I caught the most beautiful fish I had ever seen. Carefully thumbing through a fish ID booklet, I realized I just caught my first Brook Trout. Even its scientific name, Salvelinus fontinalis, meaning living in springs, captivated me and, as I committed this name to memory, I vowed to become a fisheries biologist when I grew up. Now as a professional, I value this species for reasons well beyond my childhood memories. The Brook Trout is a Jersey native. Their wild, naturally reproducing populations inhabit small streams scattered primarily across North Jersey. The species is synonymous with cold, clean water. A host of other wildlife species benefit from their presence because these streams and their watersheds receive greater protections through NJDEP regulatory programs that govern land use. My first Brook Trout encounter was definitely a life altering experience for me!

 
What is your favorite thing about your job?

The variety – no day is the same – and in particular, any fieldwork that puts me in the middle of a trout stream!

 
What do you find most challenging about your profession?

Fisheries management has become very complex. Our science is better plus there is greater public involvement in our decision-making process. I find balancing ecological, economic, and social/cultural values to be the most challenging because often there are competing interests that must be addressed as part of that process.

 
What is your favorite thing to do when you aren’t working?

Spending time outdoors fishing, especially when combined with kayaking. If the fish aren’t biting, it’s still a win-win.

 
Name one thing you can’t live without.

Water. Pure and simple.

Please join us on Wednesday, October 28, 2015, from 6:00 – 9:00 p.m. at Duke Farms in Hillsborough, New Jersey to honor the contributions that Pat Hamilton, MacKenzie Hall and Tanya Oznowich have made to wildlife in New Jersey.

 

This year’s very special event will feature keynote speaker Governor Christine Todd Whitman. The event will also celebrate CWF’s past decade of honoring women for their success in protecting, managing, restoring, and raising awareness for the Garden State’s endangered and threatened wildlife species.
