Lily Life in Polish Forests

Study Sites

Wolski Forest – oak–hornbeam community
Mount Chełm – oak–hornbeam community
Hrabeński Forest – mountain beech stand

Methodology
Researchers established 10 plots of 100 m² in each forest from 2018 to 2023. They recorded plant diversity and measured habitat variables:

Soil moisture
Ground‑level light intensity
Overall vegetation height

Key Findings

Forest	Species Richness	Soil Moisture	Light at Ground Level	Vegetation Height	Lily Stems
Hrabeński	Highest	Highest	Brightest	Tallest	Most mature
Wolski Forest	Moderate	Moderate	Lower	Shorter	Young stems
Mount Chełm	Moderate	Moderate	Lower	Shorter	Young stems

Hrabeński Forest showed the richest plant community and optimal conditions for lily growth. All stems were mature or older, suggesting a stable population.
Wolski Forest and Mount Chełm had fewer lilies, with only young stems observed; no new seedlings were found in Hrabeński.
Taller mature stems at Hrabeński may benefit from shading by neighboring plants, reducing light stress. In contrast, dense canopy in Wolski Forest limits light, keeping stems shorter.

Seasonal Influence
The spring and summer of 2019 were exceptionally favorable, boosting lily growth across all sites. However, the response varied by location, highlighting unique temporal dynamics.

Implications for Conservation

Hrabeński Forest appears the healthiest and most resilient long term.
Wolski Forest and Mount Chełm require ongoing monitoring over many years to assess how lilies adapt to changing environmental conditions.
