## Warmer winters are disrupting a hidden world beneath our feet – and it coudl impact spring growth
Stephanie Kivlin
Plants rely on a symbiotic relationship with mycorrhizal fungi – networks of fungal threads that connect to plant roots. These fungi help plants absorb essential nutrients like nitrogen and phosphorus from the soil.In return, plants provide the fungi with sugars produced through photosynthesis. This mutually beneficial exchange is crucial for ecosystem health.
However, warmer winter temperatures and altered precipitation patterns are throwing this delicate balance off.
### The problem with rain and warm spells
Traditionally, a consistent snowpack has insulated the soil, keeping it cold and slowing down microbial activity. This allows nutrients to accumulate over the winter, ready for plants to use in the spring. But with warmer temperatures, we’re seeing more rain-on-snow events and reduced snow cover overall.
This leads to “nutrient leaching,” where water washes away vital nitrogen and phosphorus from the soil before plants can access them.Research shows this is happening across a range of ecosystems. Studies have documented nutrient loss in Colorado’s mountain grasslands, New England’s temperate forests, and the Midwestern United States. A 2023 study published in *Nature Climate Change* found that rain-on-snow events significantly increased nitrogen loss in forest ecosystems. (Rustad et al., 2023)
Moreover, warmer winters can lead to soils freezing for longer periods, suppressing microbial activity and reducing the availability of nutrients when plants need them most in the spring. This can create a “timing mismatch” where plants are ready to grow, but the fungi haven’t yet ramped up their activity to provide the necessary nutrients.
### The future of changing winters
These changes – nutrient leaching, frozen soils, and timing mismatches – all contribute to reduced spring growth. The extent of this reduction will vary depending on the ecosystem and the severity of the winter warming.
Ecosystems do have the capacity to adapt. Plants might adjust to lower nutrient levels, or species might shift their ranges to find more suitable conditions. However, the ability of both plants and mycorrhizal fungi to adapt quickly enough to keep pace with the rate of climate change remains uncertain. Research is ongoing to understand these adaptive capacities.
