Restoring the Tidal Wetland at Ksu'ksw Mqoqt/Hemlock Marsh

On November 28 and 29, SMU and CBWES representatives joined the Confederacy of Mainland Mi’kmaq (CMM), Nova Scotia Department of Agriculture (NSDA), as well as the Department of Communities, Culture, Tourism and Heritage, to direct and support the decommissioning of the dyke. Over the next week, the team completed the decommissioning of the dyke and the removal of the aboiteau, to ultimately support the restoration of a tidal wetland.

How Would A Green Shores® Certified Project Stand Up in a Hurricane?

Green Shores® projects aim to build resiliency for shorelines by restoring natural processes that can be disturbed by human infrastructure and activity. Hard armour infrastructure such as bulkheads reflect wave energy causing the sediment at the base of the structure to be swept away through a process called scouring. This makes the hard armour structure highly vulnerable to collapse or failure. Soft infrastructure is designed to absorb wave energy. For example, planting native vegetation helps dissipate wave energy through friction, allowing for reduced erosion and deposition of sediments on the shore (ANCRIM, 2017). The Green Shores Credits and Ratings systems reward the maintenance of natural shorelines or restoration through removal of hard armouring. By creating a more natural, vegetated shoreline interspersed with organic materials, Green Shores projects also improve habitat quality for important species, such as herons or turtles, while also improving their resilience to hurricanes.

Hurricanes - a threat to Atlantic shorelines and waterfront infrastructure

Hurricanes originate in warm tropical waters, where an area of low air pressure and thunderstorms produces a tropical cyclone that then draws the warm water into the air. The intense winds and rain follow global oceanic currents up the Atlantic coast and are thought to move warm tropical air and water north, distributing that heat to the cooling northern climates. Hurricane force winds typically exceed 117km/hr, and can reach 250km/hr or more (Environment and Climate Change Canada, 2018)!

How to Get Started with Green Shores® for Homes

From predicted sea level rise, to increased strength and frequency of extreme weather events, the effects of climate change are being seen coast to coast. Resulting issues such as flooding and erosion can be damaging to property and concerning to shoreline property owners! While in Nova Scotia, the most common shoreline protections are hard armour solutions such as berms, dykes, and bulkheads (OECD Report, Responding to Rising Seas, 2019), these solutions are often costly, and contribute to coastal squeeze. In contrast to hard armouring solutions, nature-based solutions work to integrate natural shoreline features and restore and protect natural shoreline ecosystems.

If you are a coastal or lakeshore property owner looking to help protect your property and are interested in getting started with the Green Shores for Homes program, keep reading! This article breaks down how to get started on your own Green Shores for Home project and provides links to inspiration projects completed on the West Coast.

Coastal Nature-Based Infrastructure Workshop Series 2022

From June 26-30, TransCoastal Adaptations hosted a combined event in collaboration with the National Research Council and Coastal Zone Canada’s Cold Regions Living Shorelines Community of Practice. The Nature-Based Infrastructure for Coastal Resilience and Risk Reduction Symposium and the Climate-Resilient Coastal Nature-Based Infrastructure Workshop connected practitioners, coastal engineers, natural and social scientists, professors, students, planners, politicians, and Indigenous groups. Attendees came from across Canada and the United States to network and share the latest research in coastal and estuarine science.

Nature-Based Infrastructure for Coastal Resilience and Risk Reduction Symposium (June 26–27)

The first event was a two-day symposium for project partners from the Nature-Based Infrastructure for Coastal Resilience and Risk Reduction project. On the first day, project partners met and collaborated on the development of a national engineering guidance document for coastal nature-based infrastructure. This writing workshop was particularly exciting as it was the first time that project partners had formally met in person since the project started in July 2020.

Making Room for Wetlands: In Review

Watch the recording our popular webinar, Making Room for Wetlands: In Review.

This March, TransCoastal Adaptations, in partnership with the Society for Ecological Restoration, hosted a webinar event reviewing the five-year project Making Room for Wetlands: Implementation of Managed Realignment for Salt Marsh Restoration and Climate Change Adaptation in Nova Scotia. This research and restoration work was funded by the Department of Fisheries and Oceans’ Climate Restoration Fund and Nova Scotia Agriculture.

Green Shores Training in the Maritimes: Highlights from 2021

TransCoastal Adaptations has partnered with the Stewardship Centre for British Columbia to bring Green Shores training to the Maritimes.

Green Shores training helps to promote understanding of Green Shores as a framework for nature-based solutions. The training also helps build capacity among both shoreline practitioners and individuals with a general interest in shoreline ecosystem protection.

There are three levels of Green Shores training offered. Level 1 introduces participants to the Green Shores program, including its rationale, benefits, and application. Level 2 offers more in-depth information about how to apply the Green Shores credit and rating systems to shoreline management projects. Level 3 is intended for shoreline practitioners who want to be formally recognized as a Green Shores Approved Professional.

Green Shores Training in the Maritimes: Notes from the Field

In November 2021, 16 people from Nova Scotia and New Brunswick took part in Green Shores Level 1 and 2 training at Saint Mary’s University. The diversity of their career background speaks to the adaptability of the Green Shores program: participants included urban foresters, civil engineers, asset management specialists, students, wetland coordinators at NGOs, and government climate change specialists. The training sessions also served as a networking opportunity between government, academics, NGOs, and industry, which was appreciated by many participants. At least two collaborative project proposals for shoreline design have already been submitted from connections formed during the training sessions.

Over the three days, a little over half the time was spent in the classroom. There, trainees learned about the Green Shores program, got a crash course in geomorphology and coastal erosion, and worked in groups on evaluating public park and home shoreline plans.

The field visits were the highlight of the course for most participants despite the cold, windy, and rainy Maritime November weather. In Level 1 training, participants applied their newly gained skills for the first time at Conrose Park in Halifax in torrential rain, where they worked in groups to plan a Green Shores design to slow heavy erosion at the site.

Level 2 training included an excursion to homes along the Northwest Arm for trainees to create home shoreline designs. Home shoreline design offered a more in-depth approach to Green Shores, since the trainees had to consider existing gardens, docks, boat access, public right of ways, and residential aesthetics in their designs.

The final day’s field excursion took place in Point Pleasant Park where the rough waves called for a greater focus on shoreline processes and how nature-based solutions can attenuate wave action. Point Pleasant Park was an excellent site for the excursion because it has numerous beaches with differing slopes and a variety of rock sizes. The Point Pleasant afternoon concluded with creating a design for a park area that took into consideration erosion, rising sea levels, vegetation, public use, and historical importance.

The restoration of this beautiful place as an oasis of biodiversity in the urban environment is one of this board’s proudest achievements.” – Vancouver Park Board chair, Stuart Mackinnon.


Green Shores: Nature-based vs. Hard armoured shorelines

Why use Green Shores?

Green Shores uses nature-based shoreline solutions to protect shoreline property and provide benefits for people, wildlife, and the environment. A Green Shores approach is more cost-effective and resilient to climate change and sea-level rise than hard armouring solutions. Conventional hard armouring such as bulkheads and seawalls disrupt natural shoreline functions, which can worsen erosion and degrade the shoreline. 

Read on to learn about the many benefits associated with Green Shores:

GSH TCA Poster 2021 FINAL.jpg

Physical processes 

Green Shores restores physical processes that promote the natural movement of water and sediment needed to maintain healthy shorelines. Green Shores also protects shorelines from erosion and flooding through soft shore protection, which includes re-sloping, beach nourishment, introducing large woody materials, and planting riparian or intertidal vegetation.

Habitat and biodiversity 

Green Shores provides more suitable habitat for aquatic and terrestrial insects, plants, birds, fish, and other wildlife, increasing the overall biodiversity of the shoreline. Green Shores incorporates native vegetation that is better adapted to shoreline conditions and does not require irrigation or chemical fertilizers. This vegetation provides food and shelter for native fish and other wildlife, while also preventing erosion.

Cost-effective 

Green Shores and other nature-based, soft shoreline solutions can be 35-70% cheaper to install and maintain than hard alternatives (bulkheads, seawalls) (Green Shores 2020: Impact, Value and Lessons Learned, ESSA). Additionally, Green Shores projects achieve high returns on investment and provide important environmental and societal benefits. For example, analysis suggests that each $1 invested in Green Shores for Shoreline Development (GSSD) program delivery generated $7.10 in social benefit in British Columbia, which is a 1:7 cost-benefit ratio (ESSA).

Free of contaminants and pollutants 

Green Shores prevents and reduces pollutants entering the aquatic environment, resulting in better water quality. Hard armoured structures may introduce toxic compounds and pollutants (such as creosote-treated bulkheads or dock pilings) into aquatic environments. Replacing hard armouring with soft shore approaches such as gravel, logs and vegetation helps to filter water and reduce pollutants entering aquatic environments. Green Shores  also improves water quality by reducing run-off from upland through the use of less impervious surfaces.

Salmon 

Green Shores provides spawning habitat for salmon and natural cover for juvenile salmonids using a network of branches, trunks, stems, and roots. Additionally, overhanging vegetation provides important organic input to the aquatic environments that juvenile salmonids feed on. On the other hand, bulkheads, seawalls, and other hard armour approaches do not support fish habitat and instead disrupt food chains and migration paths, contributing to ‘coastal squeeze’ - the serious loss of intertidal habitat. 

GSvsHardAmrour5-1024x493.png

Natural and Beautiful 

Green Shores enhances the natural beautyof shorelines by using native vegetation that thrives in local conditions, providing wildlife viewing opportunities, and providing access to waterfront shorelines and activities.

Water Quality 

Green Shores improves local water quality by reducing stormwater runoff. The native shoreline vegetation encouraged by Green Shores uses an associated network of branches, trunks, stems, and roots to filter upland run-off and enhance infiltration and retention of rainwater.

Planned Research in the Chignecto Isthmus

On May 20, partners and stakeholders gathered virtually to present and discuss plans for research taking place in the Chignecto Isthmus to study nature-based infrastructure and its role in mitigating coastal flood and erosion risk in Canada. You can watch our project partners present on this research project with the video to the right.

The Chignecto Isthmus is highly vulnerable to coastal hazards and is one of four study sites selected for the Nature-Based Infrastructure for Coastal Resilience and Risk Reduction project. Research at this site is being led by the National Research Council of Canada in partnership with TransCoastal Adaptations at Saint Mary’s University, Queen’s University, and Natural Resources Canada - Geological Survey of Canada.

Field research and hydrodynamic modelling in Chignecto Bay will take place throughout the Summer, Fall and Winter of 2021. Ultimately, this project will produce a design guidance for coastal infrastructure in Canada, as well as a knowledge base and analytical tools to assess site suitability for nature-based infrastructure.

At the May 20 meeting, stakeholders reported important changes to local dyke infrastructure, and identified a planned marsh restoration project aligned with planned research. The group also discussed the need for updated and accurate bathymetric data of the upper portion of Chignecto Bay. Stakeholders stated support for the research project, and stressed the need to identify solutions to high risk storm surges in the Isthmus. 

Data Needed

We are actively searching for current bathymetric data of the Chignecto Bay. If you or your organization has relevant data they would like to share with us for the purposes of this project, please contact Danika Van Proosdij at dvanproo@smu.ca. Likewise, contact us if your organization has interest in funding data collection or if you have information regarding recent dyke breaching or overtopping in the Chignecto Bay area.
