Is Reindeer Moss Sustainable?

Despite its common name, reindeer moss (Cladonia rangiferina) is actually a lichen — a symbiotic organism made of fungi and algae. Unlike true mosses, lichens have no roots and grow exceptionally slowly, often only 3 to 11 millimeters per year.

Because it grows so slowly, it can't be farmed commercially like a traditional crop. Every piece of reindeer moss used in an acoustic panel or wall installation was removed from a wild, natural ecosystem.

To supply the demands of interior design, reindeer moss is harvested en masse from boreal forests and arctic tundra regions, particularly in Scandinavia and Northern Canada. In these subarctic environments, lichen plays a vital ecological role:

• Ecosystem foundation: it acts as a primary ground cover that prevents soil erosion, retains moisture, and provides micro-habitats for insects and microorganisms.
• Vital food source: it's the primary winter food source for wild reindeer and caribou. Stripping large swaths of ground lichen starves local wildlife and disrupts fragile food webs.

Because regrowth takes decades, heavy harvesting strips these slow-recovery ecosystems bare, leaving long-lasting ecological damage behind.

Preserved reindeer moss is sold as a zero-maintenance product, but it relies on ambient humidity to stay pliable. In dry indoor environments — especially air-conditioned offices and heated commercial spaces — ambient humidity frequently drops below 40%. When humidity drops, preserved lichen undergoes a drastic shift:

• Brittle & shedding: the lichen dries out, loses its flexibility, and turns brittle. Touching it or brushing past it causes it to crumble and shed onto floors and furniture.
• Air quality hazards: as the dried lichen crumbles, fine dust and particulate matter are released into the air, degrading indoor air quality and creating allergen hazards for building occupants.
• Fading & waste: preserved moss is heavily dyed using synthetic chemicals and salts. As it deteriorates, colors fade, leaving unsightly patches that lead to complete tear-outs and landfill waste.

Preserved moss walls and static biomorphic decor are non-living materials. While they mimic green shapes, they miss the core mechanism of biophilia: connecting humans to active, living nature. Live plants stand far above preserved options as the ultimate biophilic solution because of their direct impact on human health and workplace performance:

• Active indoor air purification: live plants actively transpire, increasing healthy indoor humidity while pulling volatile organic compounds, carbon dioxide, and airborne particulate matter out of the air. Preserved moss does none of this — and, as it breaks down, degrades air quality instead.
• Measurable stress and cortisol reduction: interacting with and simply being in the presence of living plants lowers blood pressure, reduces autonomic nervous system stress, and decreases salivary cortisol levels far more effectively than static, preserved replicas.
• Cognitive performance and mood enhancement: studies consistently show that live indoor foliage boosts focus, enhances creative problem-solving, and decreases physical symptoms of fatigue and headaches among office workers.
• The dynamic human connection: true biophilia responds to the dynamic, living world. Live plants grow, unfurl new leaves, change with the seasons, and respond to light. This subtle, living movement fosters a psychological connection to the natural world that static, preserved panels simply can't replicate.
