Conservation teams in Canada's Niagara River are using recycled Christmas trees to restore fish habitat, with 75% of the original coastal wetlands having disappeared on the Canadian side. A program launched in 2016 has installed 1.64 kilometers of habitat structures, including those made from dead Christmas trees, anchored into the riverbed to slow waves and reduce erosion. The goal is to recreate natural conditions for fish and other aquatic life by providing sheltered areas where they can feed, breed, and grow. This approach uses recycled materials, rather than relying on new manufactured structures, to rebuild physical conditions needed for aquatic life.

What if a discarded Christmas tree could help bring a damaged river ecosystem back to life?
uncertain
tree → discard → life
For years, the Niagara River’s shoreline has been losing an important part of its natural ecosystem.
asserted
shoreline → lose → ecosystem
More than 75% of the original coastal wetlands on the Canadian side had disappeared, reducing the shallow, sheltered areas that fish need for feeding, breeding and growing.
asserted
fish → disappear → feeding
In response, conservation teams began using an unusual but practical material: dead trees, including recycled Christmas trees, anchored directly into the riverbed.
asserted
teams → begin → riverbed
The structures help slow waves, reduce erosion and create calmer areas where aquatic life can thrive.
asserted
life → slow → areas
According to Niagara Parks, the coastal wetland restoration programme began in 2016 in partnership with the Ontario Ministry of Natural Resources and Forestry and Environment and Climate Change Canada.
uncertain
programme → accord → Canada
The programme was designed to restore shoreline habitat at strategic locations along the Niagara River.
asserted
programme → design → River
A 2025-26 Niagara Parks sustainability report says that 1.64 kilometres of habitat structure have now been installed in the Upper Niagara River, with additional work continuing at sites including Black Creek and Boyer’s Creek.
asserted
work → say → Creek
Why the loss of wetlands mattered
asserted
loss → matter → wetlands
They provide sheltered, shallow-water environments that can serve as nursery habitat for young fish.
asserted
that → provide → fish
When these areas disappear, species lose places where they can feed, reproduce and find protection from stronger currents.
asserted
they → disappear → currents
According to Niagara Parks, the loss of more than three-quarters of the original coastal wetlands had removed important fish nursery habitat and severely affected species including lake sturgeon and muskellunge.
uncertain
loss → accord → sturgeon
The restoration programme therefore focuses not only on stopping shoreline erosion but also on rebuilding the physical conditions needed for aquatic life.
asserted
programme → focus → life
Instead of relying entirely on new manufactured structures, conservation workers have reused natural materials that would otherwise have been discarded or chipped.
asserted
that → rely → materials
How old Christmas trees became fish habitat
One of the most distinctive parts of the project involved recycled Christmas trees.
asserted
One → become → trees
Niagara Parks anchored trees into the riverbed, where they act as underwater structures that interrupt wave energy and create calmer conditions near the shore.
asserted
that → anchor → shore
The idea is to recreate some of the complexity that naturally fallen trees can provide in waterways.
asserted
trees → recreate → waterways
Branches and trunks create physical cover and additional surfaces in the water, potentially giving fish and other aquatic organisms places to shelter.
asserted
Branches → create → places
At Boyer’s Creek in 2019, Niagara Parks planned to repurpose a roughly 30-foot blue spruce that had been displayed in Queen Victoria Park during the holiday season.
asserted
that → plan → season
Rather than sending the tree for disposal, the park intended to use it as anchoring material in the riverbed.
asserted
park → send → riverbed
The programme has also made use of ash trees affected by the emerald ash borer.
asserted
programme → make → borer
Rather than simply removing and disposing of these dead trees, some have been incorporated into shoreline restoration projects.
asserted
some → remove → projects
Building a more natural shoreline
The restoration effort has expanded beyond Christmas trees.
asserted
effort → build → trees
Niagara Parks has also experimented with anchoring fallen ash trees to their remaining stumps so they can rest on the riverbed, imitating the way trees naturally fall into waterways.
asserted
trees → experiment → waterways
These structures can provide what conservationists call instant fish habitat while also helping protect the shoreline.
asserted
conservationists → provide → shoreline
Riparian zones, where land meets water, can provide food and shelter for aquatic organisms, regulate water temperatures and help resist erosion.
asserted
land → meet → erosion
The programme has grown considerably since the early projects.
asserted
programme → grow → projects
Niagara Parks' latest sustainability report says 1.64 kilometres of habitat structure have now been installed in the Upper Niagara River.
asserted
kilometres → say → River
In summer 2025, crews added structures at the mouths of Black Creek and Boyer’s Creek, including 70 tree and log structures and more than 360 tonnes of boulders.
asserted
crews → add → boulders
Together, that work created approximately 240 metres of additional coastal wetland habitat.
asserted
work → create → habitat
A restoration project with wider benefits
The results are intended to extend beyond shoreline protection.
asserted
results → intend → protection
Niagara Parks reports that restoration efforts have already been associated with increased fish and shorebird populations and greater diversity, along with improved water quality at restored sites.
asserted
efforts → report → sites
What began as an effort to repair a heavily altered shoreline has therefore developed into a broader ecological restoration programme.
asserted
began → begin → programme
By turning unwanted trees into structures that resemble natural river habitat, conservationists are giving the Niagara River's shoreline another chance to function more like a living ecosystem.
asserted
conservationists → turn → ecosystem
The unusual use of recycled Christmas trees is a reminder that restoration does not always require entirely new materials.
asserted
restoration → require → materials
Sometimes, discarded parts of the landscape can become the building blocks for bringing damaged habitats back to life.
asserted
parts → discard → life
