Abstract
Under-canopy natural regeneration of Scots pine (Pinus sylvestris L.) stand is able to create stands with a complex structure, which are characterised by greater resistance to extreme phenomena related to climate change. The main aim of the work was to analyse the potential of pine undergrowth, its role in the stand, and its usefulness in further breeding plans to create stands of various structure, with greater stability and tolerance to stress factors, including greater resistance to climate change. The study was carried out in north-eastern Poland, in pine stands thinned by strong (hurricane level) wind in 2002. The study area covers 225.2 ha and is located in 29 stands. Naturally regenerated pine saplings with a minimum height of 0.5 m, characterised by a high density, growing under the upper cover of the stand, with varying degrees of thinning, were qualified for the study. On average 7.820 pine saplings were recorded in the area of one hectare. Over 65% of the examined saplings were determined to be of very good or good quality, prognostic for further development and the creation of the main stand in the future. The principle of increasing the structural diversity of stands is the method of increasing the adaptability of forests to environmental changes.
Highlights
Worldwide, climate change has posed a significant threat to forests due to the increasing heat and aridity, shifting rainfall patterns and extreme weather events [1]

Pine saplings were divided into three development categories using data collected from 6860 individuals pine saplings, under-canopy natural regeneration, growing in 65 clumps
Summary
Climate change has posed a significant threat to forests due to the increasing heat and aridity, shifting rainfall patterns and extreme weather events [1]. Temperature variation, precipitation, and long-term changes in vegetation [5] are among the most important factors influencing forest stand structures [6,7,8,9]. The main reasons for the potential tree range changes will be an increase in carbon dioxide concentration and an increase in the average global temperature [12,13]. In this situation, forest management faces a great challenge to develop methods of silviculture to maintain the health and vitality of forest ecosystems at a sufficiently high level [14,15], which will ensure the emergence of healthy, climate-resistant stands, which can be regenerate naturally
