Over the past two decades, artificial snow has seen widespread use in tourist resorts, fueling a boom in ski tourism. However, this rapid growth has come at a significant environmental cost. Environmental researchers have warned that artificial snow often contains harmful chemicals and bacteria that damage vegetation, contaminate water sources, and pose a threat to local wildlife. Studies have also confirmed that its negative impact extends to reducing plant diversity and causing a noticeable decline in overall biodiversity.
Why Are Additives in Artificial Snow Raising Alarm Among Researchers?
According to a study published in ScienceDirect, artificial snow requires vast amounts of energy and water, leading to significant resource waste. However, the primary concern lies in the additives used in its production. One such additive is a bacterium known as Pseudomonas syringae—a plant pathogen that is commonly detected in water sources at varying concentrations. Although this bacterium is rendered inactive and non-viable in artificial snow, researchers are now questioning whether these inactive components and dead bacterial particles could still impact the environment and living organisms.
The Environmental Consequences of Tourist Ski Slopes

A closer examination of the environmental impact of tourist ski slopes reveals several alarming consequences, particularly in relation to the stress artificial snow places on vegetation. These impacts include:
Soil Freezing
The compacted artificial snow layer facilitates the infiltration of cold and moisture into the ground, leading to the freezing of water within the soil. This process damages plant roots and disrupts deeper geological processes.
Formation of Ice Layers on Vegetation
Artificial snow can lead to the formation of ice layers that block gas exchange between plants and their surroundings. These layers also hinder photosynthesis by preventing sunlight from reaching plant surfaces, ultimately causing gradual plant death.
Mechanical Damage
The machinery and equipment used to groom artificial snow on ski slopes can harm the topsoil layer, leaving vegetation vulnerable to drying out and erosion.
Delayed Plant Growth
Artificial snow reduces plants’ ability to regenerate and survive, impacting not only the vegetation itself but also the organisms that rely entirely on these plants for food.
How Does Artificial Snow Affect Mountain Ecosystems?
The environmental impact of artificial snow is not limited to local areas—it extends to fragile mountain ecosystems as well. According to Innovation Origins, the following effects have been observed:
Increased Input of Water and Ions into Slope Soil
This disrupts the natural soil balance and alters the native vegetation composition.
Use of Additives Containing Bacteria
These bacteria can accelerate soil freezing, further harming plant life.
Disruption of Alpine Plant Growth
The disappearance of native mountain plants has prompted growing concern and the need for further research into the long-term ecological risks of these changes.
Artificial Snow and Wildlife
Studies have highlighted the environmental damage caused by ski slopes and their impact on wildlife. Research has documented the distress experienced by species such as the black grouse, which suffers from high levels of stress when its habitat is located near ski resorts. The noise generated by snow cannons, along with the presence of heavy machinery, disorients animals and destroys their natural habitats, leading to higher mortality rates among both birds and mammals due to collisions with equipment.
For these reasons, it is crucial to explore improved methods of snow production that minimize environmental harm. This includes moving toward more sustainable practices that rely on pure water without chemical additives, and closely monitoring water and energy use by enhancing the efficiency of snow-making equipment. Such measures are essential to protecting biodiversity and maintaining ecological balance in both mountain and local environments.
