The research was undertaken due to the lack of synthetic studies and collections concerning monumental trees in the spa towns in Poland. We investigated all 45 towns with such a status. The article presents the numerical and species data of the nature monument trees. For individual species, the average breast height diameter is also given. A database of nature monuments was created (separately for...
In 2014−2015, the General Directorate for Environmental Protection carried out an inventory of natural monuments in Poland. The data collected during this process was used to update and expand the generally available Central Register of Nature Protection Forms (CRFOP). Based on these material, the assignment of nature monuments to particular categories was verified and their number in individual categories...
Currently in Poland there are 36,570 natural monuments (registry items). 94% of them are trees, growing as individual specimens (28,304 natural monuments), in groups (5,551) and in alleys (525). In total, this gives a number of at least 123,784 monumental trees. All of them now have the same status of a ‘natural monument’. Meanwhile, among this huge number of trees there are both average specimens...
The paper presents the issue of conservation of species diversity of the Białowieża Forest in the context of both natural and human−related disturbances. These disturbances, in the authors’ opinion, were the main factor that shaped the unique species diversity of this area. Examples of natural disturbances occurring in the Białowieża Forest include the impact of wind, insect outbreaks and, to a lesser...
One of the greatest challenges of nature conservation is to identify and locate networks of pro tected areas, which will preserve the biodiversity. The paper aims to show the ornithological value of the Sobibór Forests (E Poland) and to emphasize the fact that the network of Important Bird Areas (IBA) and Special Protection Areas within Natura 2000 (SPA) may require additions. The study was conducted...
The paper presents the main results of the comprehensive inventory of monumental trees in the Strict Reserve of the Białowieża National Park, which was conducted in years 2002−2017 on an area of ca. 4700 ha and included all live trees with diameter at breast height (dbh) exceeding a minimum threshold value ranging from 60 cm for hornbeam to 120 cm for oak. For every tree fulfilling this condition,...
In the EU countries a forest management plan is a common, however not always obligatory, document updated every 10 years. According to the type of the forest property and its area it may differ in terms of the form and specifity. The forest management in Poland has a long history dating back to the end of 18th century. Nowadays, before each new decade, there is a discussion on the changes, which may...
