Sand dunes are natural landscapes that can be found wherever loose sand is blown, most typically in deserts or on beaches.
They serve as a habitat for many interesting and rare species of animals and plants, as well as acting as a place of recreation for people from local communities or further afield. But due to activities by humans as well as erosion, sand dunes in some places may be under threat.
The hope of World Sand Dune Day is to draw attention to these amazing natural features and encourage individuals, families and communities to get involved in caring for them in a protective, restorative way.
World Sand Dune Day Timeline
Early Scientific Description of Sand Dunes
Scottish physicist James D. Forbes publishes observations of wind-blown sand and dune forms, helping establish dunes as geomorphic features shaped by aeolian processes rather than random heaps of sand.
Founding of the Dune du Pilat Observatory Tradition
French geographer Georges Lacombe begins systematic measurements and mapping of the Great Dune of Pilat on the Atlantic coast, providing one of the earliest long-term records of dune movement and growth.
Creation of Michigan’s First State Park Dune Protections
Michigan designates several Great Lakes dune areas within its state park system, an early governmental step recognizing coastal sand dunes as scenic and ecological resources needing protection and public management.
Ramsar Convention Elevates Coastal Wetlands and Dunes
The Ramsar Convention on Wetlands is adopted, creating a global framework to protect wetlands, including many coastal sites where dune systems are integral parts of listed habitats and management plans.
EU Habitats Directive Prioritizes Dune Habitats
Implementation of the European Union Habitats Directive leads to coastal dunes being listed as priority habitats, driving the designation of numerous dune-rich Natura 2000 sites across Europe for strict conservation.
Great Sand Dunes National Monument Expanded for Ecosystem Protection
In the United States, Great Sand Dunes National Monument in Colorado is expanded to include more of the surrounding dune and hydrologic system, reflecting a shift from scenic preservation to ecosystem-scale dune conservation.
Michigan Establishes Critical Dune Area Program
Michigan enacts the Sand Dune Protection and Management statutes that create “Critical Dune Areas,” formally recognizing Great Lakes coastal dunes as a globally significant resource and regulating development to preserve them.
How to Celebrate World Sand Dune Day
Consider some of these ideas for how to get started with celebrating World Sand Dune Day:
Attend World Sand Dune Day Events in the UK
The different organizations that support World Sand Dune Day will host various events and activities at different sites.
The schedule changes each year and is based on location, but some activities might include explorations, tours, crafts for kids, spider hunts, butterfly walks, bird walks, orchid walks, art workshops for adults and so much more!
Check out the activities calendar at your local sand dune for more information, or find event listings by location at the Dynamic Dunescapes website.
Visit a Sand Dune Area in the US
An excellent way to celebrate World Sand Dune Day might be to head over to the closest national park or other sand dune and pay a visit.
While there, be sure to follow all of the safety and conservation rules, and also don’t forget to clean up after yourself! Check out some of these popular sand dune destinations in the US:
- Pacific City Sand Dunes in Oregon
- Algodones Dunes and Imperial Sand Dunes in California
- Jockey’s Ridge State Park Sand Dunes in North Carolina
- Sleeping Bear Dunes National Park in Michigan
Support a Sand Dune Charity
Those who aren’t up for a visit to a sand dune park but would like to participate in the day can certainly make a difference by providing a donation to a worthy cause.
Different charities have been started to protect the sand dunes in different states and countries around the world. Find out through an online search which one is local and then get connected!
History of World Sand Dune Day
World Sand Dune Day was started in 2021 as a collaboration between two organizations, Dynamic Dunescapes and Sands of LIFE, both projects which are working to protect and restore coastal sand dune systems in the UK.
In Ireland, the day is celebrated and supported by the organization called Clean Coasts. Other communities and organizations dedicated to sand dunes also celebrate this day in places all throughout the globe.
This event was founded with the purpose of highlighting the importance of sand dunes for their various ways they serve the ecosystems.
This includes biodiversity, acting as a home to many different species of plants and animals, as well as serving as a barrier from waves and surges. In addition, World Sand Dune Day also highlights the recreation that sand dunes provide for humans.
Facts About World Sand Duke Day
Shifting Sand Dunes Can “Walk” Across the Landscape
Under the right conditions of wind strength, direction, and sand supply, whole dunes can migrate several meters per year, a process sometimes called dune “walking.”
In some desert dune fields, barchan dunes have been recorded moving tens of meters annually, while coastal foredunes typically migrate more slowly but can still shift landward over decades, reshaping shorelines and burying vegetation or infrastructure in their path.
Coastal Dunes Act as Nature’s Storm Shields
Vegetated coastal sand dunes form a raised barrier that absorbs wave energy and storm surge before it reaches inland areas.
Studies and management guidance from U.S. coastal agencies show that healthy dune ridges can significantly reduce flooding and erosion during hurricanes and nor’easters, functioning as a first line of defense and a reserve of sand that can be eroded during storms and then gradually rebuilt afterward.
Marram Grass Is a Keystone Engineer of European Dunes
On many North Atlantic coasts, including the UK and Ireland, marram grass (Ammophila arenaria) is the dominant dune-building plant, with deep, dense rhizomes that bind loose sand and encourage dunes to grow upwards and landwards.
Its ability to tolerate burial and trap windblown sand makes it a classic “ecosystem engineer,” and conservation projects often rely on protecting or reintroducing marram to restore damaged foredunes.
Over‑Stabilized Dunes Can Lose Their Rarest Wildlife
For much of the twentieth century, managers often tried to fix dunes in place using tree planting, fencing, and intensive vegetation, but ecologists have since found that locking dunes down can push out species that depend on open, shifting sand.
European conservation projects now deliberately re‑mobilize parts of “over‑stabilized” dune systems, scraping back vegetation or exposing bare sand to recreate the dynamic conditions needed by rare plants and invertebrates.
Human Foot Traffic Measurably Degrades Dune Structure
Field studies on Atlantic barrier islands in the United States have documented that repeated trampling by beachgoers reduces plant cover, breaks stems, and compacts dune sands, which lowers dune height and makes them more vulnerable to storm erosion.
Research comparing walked and protected plots has shown that even informal footpaths can significantly weaken dune resilience, which is why many coastal managers install boardwalks and fencing to keep people off sensitive areas.
Mount Baldy Shows How Quickly Dunes Can Be Damaged and Repaired
At Indiana Dunes National Park, the large migrating dune known as Mount Baldy had to be closed to free roaming after erosion and visitor trampling destabilized its surface and created hazardous conditions.
The National Park Service now actively manages the site with vegetation restoration, controlled access, and monitoring, using it as a high‑profile example of how human use and natural sand movement interact on big dunes along the Great Lakes.
Dune Restoration Is Emerging as a Climate Adaptation Tool
Coastal scientists and conservation groups increasingly treat dune restoration as a form of “green engineering” that can complement or replace hard sea defenses.
Projects from Delaware to California and Puerto Rico use techniques such as sand fencing, native planting, and strategic sand placement to rebuild eroded dunes, aiming to create living buffers that can adapt to rising seas and stronger storms while also providing habitat for coastal species.
