    Opis:
    Oak and lime trees constitute nearly 2/3 of an overall number of trees considered as nature monuments in Poland. Being exposed to a number of agents their health condition often is poor. The wood−decaying fungi are the major age−limiting agents for trees. This paper presents the results of studies on the presence of various fungal species on 160 oak and lime trees. The author makes an attempt to define associations of fungi causing wood decay in ancient oak and lime trees in Poland.

    Opis:
    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 was calculated. In addition, the species composition of trees being single monuments of nature and growing in monumental groups and alleys was determined. The total number of monumental trees in Poland was also calculated, with the division into species. For the 50 of most popular individual monument tree species, the minimum, maximum and average circumferences of their trunks were determined. A group of the most impressive monument trees with trunk circumferences exceeding 600 cm was also selected. According to the calculations, there are 36,570 natural monuments in Poland, of which 94% are trees and shrubs (individual trees – 28,304, groups of trees – 551 and alleys – 525). Individual trees natural monuments represent at least 161 species, trees growing in groups of at least 123 species, and trees growing in alleys at least 53 species. The total number of monumental trees growing as single specimens, in groups and alleys is at least 123,784 pieces, with at least 46,636 trees growing in groups, and at least 48,844 trees in alleys. In total, the monumental trees of Poland (growing singly, in groups and alleys) belong to at least 178 species, including 51 gymnosperms and 127 angiosperms. The CRFOP data also shows that there are 1641 trees that have reached or exceeded the trunk circumference of 600 cm, among which there are 77 specimens with a circumference equal to or greater than 800 cm. However these data do not coincide with information available in current literature and they need to be verified. The obtained calculations are the most up−to−date report on the numerical status of trees – natural monuments based on data confirmed by field inventory, and not only on the registers of nature monuments containing often unverified or non−actual data.

    Opis:
    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 (as for natural monuments) and endowed with special natural and historical as well as social values. The aim of this work was to propose detailed solutions for the categorization of trees as natural monuments by indicating the two new forms of protection for the Polish legislation: the National Natural Monument (a form superior to the existing natural monument) and the European Natural Monument (a form superior to the National Natural Monument and natural monument). The status of the European Natural Monument would receive exceptional trees, not only for the country, but also internationally. The proposed target number of such facilities in Poland could be from 100 to 200. On the other hand, the status of the National Natural Monument would receive trees significantly distinguishable on the scale of the country or region, compared to other natural monuments, nevertheless giving way to natural, historical and social values included in the European Natural Monument category. The estimated target number of such individuals in Poland could be from 1000 to 2000. Dimensional criteria in the form of minimum circumferences of their trunks were determined for 45 species. The age and unusual shape were indicated as additional factors necessary to take into account during assessing the natural values of trees. There are also a number of criteria, that should be taken into account during assessing historical and social values of monumental trees, such as: the existing connections with historical facts and figures, as well as the legends. A group of trees was designated for the new protection forms in the number of 1905 candidates for the National Natural Monument and 183 candidates for the European Natural Monument. Finally patterns of tables to mark them and legislative solutions for defining and setting up the National Natural Monument and the European Natural Monument were proposed.

    Opis:
    There are over 100 thousand old trees protected as nature monuments in Poland. Their health condition in many cases is not satisfying and the new methods of their conservancy against pathogenic, wood decaying fungi are necessary to be prepared. In this paper the evaluation of practical usability of some phenolic compounds naturally existing in wood is described. Natural chemical substances as eugenol, isoeugenol, resorcinol, pyrogallol and 2−furaldehyde (furanone) seem to be very useful in this matter. Artificially applied directly into the stem of living tree by hydrostatic injection, they are able to protect it from the inside as well as commonly used synthetic fungicides, being also less dangerous for the natural environment.
