Background. Greenery resources in small towns are not protected adequately due to insufficient data on their quality and quantity. The aim of the study was to identify valuable foreign tree species in the town of Bolków to protect the natural and cultural heritage.
Material and methods. The study area was the historical part of the town of Bolków, which was identified upon available archival materials. In 2016 trees of foreign origin were inventoried in that area. The analysis of historical materials, measurements of the trunk perimeter, the list of forms of nature conservation provided by the Regional Directorate for Environmental Protection in Lower Silesia and assessment of the health status were used as the criteria taken into consideration to assess the possibility of legal protection of rare and valuable trees, which could receive the status of natural monuments.
Results. 21 rare trees of 14 taxa were identified in Bolków. Most of the trees were found in the garden of former coeducational college established in 1886. All the trees are mostly located near non-historical objects. The trunk perimeter of most of the trees met the minimum limit for natural monuments in Lower Silesia. The following rare taxa were identified: horse chestnut (Aesculus hippocastanum L.) ‘Laciniata’, European ash (Fraxinus excelsior L.) ‘Pendula Wentworthii’ and Rocky Mountain ponderosa pine (Pinus ponderosa P. Lawson & C. Lawson var. scopulorum Engelm.).
Conclusions. The lack of natural monuments should not be interpreted as the lack of valuable trees in small towns. The case study of Bolków shows that valuable tree taxa do not usually grow in parks or squares. The qualitative research presented the history of greenery and horticulture of small towns in Lower Silesia.
