Pilgerodendron uviferum (D. Don) Florin is an endemic, threatened conifer that grows in South America. In the sub-Antarctic territory, one of the most isolated places in the world, some forest patches remain untouched since the last glaciation. In this study, we analyze the tree structure and tree diversity and characterize the environmental conditions where P. uviferum-dominated stands develop within the Magellanic islands in Kawésqar National Park, Chile. An environmental matrix using the databases WorldClim and SoilGrids and local topography variables was used to identify the main environmental variables that explain the P. uviferum-dominated stands. PCA was used to reduce the environmental variables, and PERMANOVA and nMDS were used to evaluate differences among forest communities. The results show that two forest communities are present within the Magellanic islands. Both forest communities share the fact that they can persist over time due to the high water table that limits the competitive effect from other tree species less tolerant to high soil water table and organic matter. Our results contribute to knowledge of the species’ environmental preference and design conservation programs.

The investigations on the role of macromycetes in various forest communities of the Świętokrzyski National ark were performed in the years 1964-1968. Fruit bodies growing on the soil, in the litter and on wood were studied on 13 permanent plots. Attention was paid to effects of atmospheric conditions on the fruiting of fungi and to the seasonal aspects of macromycetes.

Phytosociological Relevés

Non-forest communities in the western part of the Kampinos National Park were studied in the years 1991 – 1998 with regard to their phytosociological diversity and dynamic processes currently underway in them. A total of 323 phytosociological releves were prepared by the widely used method of Braun-Blanquet. These releves served as basis for identification of 31 associations and 7 meadow and sedge communities of undetermined level. 15 syntaxa were recorded in the <em>Phragmitetea</em> class, 18 syntaxa – in the <em>Molinio-Arrhenatheretea</em> class, 2 associations in the <em>Scheuchzerio-Caricetea</em> class, as well as 3 grassland associations from <em>Koelerio glaucae-Corynephoretea canescentis</em> and <em>Nardo-Callunetea</em> classes. In order to determine the character and direction of changes in phytocoenoses, 4 basic ecological processes have been distinguished – fluctuation, degeneration, regeneration and secondary succession. Within secondary succession, recreative, creative and anthropogenically forced secondary succession were distinguished.

The Emerald Ash Borer (EAB) is a wood-boring beetle native to Asia that now infests and kills ash trees (Fraxinus spp.) in North America. Many ecological communities will be dramatically altered by the mortality of ash trees caused by this invasive insect. The EAB recently colonized Point Pelee National Park of Canada in extreme southwestern Ontario, Canada, a site famous for its unusual plant and animal diversity as well as its extraordinary bird migrations. We conducted a census of breeding birds in two ash-rich mature forests at Point Pelee in order to obtain baseline data on the breeding bird communities prior to changes in forest communities that are likely to be caused by the EAB. Here we report the results of the bird census and review possible changes to the breeding bird fauna of Point Pelee that may result from ash tree mortality and the associated disruption of forest communities.

Compositional Changes

Ponderosa pine (Pinusponderosa Laws.) forest communities in Glacier National Park, Montana, were investigated to determine the effects of fire exclusion. Analysis of age data in these fire-dependent communities indicates that ponderosa pine is not reproducing itself as well as other mesophytic conifers invading these stands. In addition to these compositional changes, it was determined that fuel accumulations are greater in these park communities compared with similar wilderness area pine communities subject to more recent burning.

Communities of broadleaved forest subject to strong pressure from large herbivores underwent degeneration. The relief of this pressure led to regeneration of the community, in which an important role was played by the sallow <em>Salix caprea</em> and other light-seeded pioneer species of tree (<em>Populus tremula</em>, <em>Betula pendula</em> and <em>B. pubescens</em>). Regeneration involving <em>Salix caprea</em> proceeded following the conservatorial protection of the degenerate stands in a reserve and later in Białowieża National Park. The emergence and development of the population of <em>Salix caprea</em> proceeded following the invasion of spruce, which coincided with the period of enhanced animal pressure on broadleaved forest. <em>Salix caprea</em> filled all the gaps in the tree stand arising as a result of the destruction of trees and undergrowth by herbivores (in the years 1892-1915). It also appeared en masse on old, at that time unforested, clearings and felled areas. In these places, <em>Salix caprea</em> created very abundant populations, with particular trees being in good condition, with a habit typical of forest trees and attaining considerable heights. The majority of trees were 50-60 years old at the time of death, although individuals reached 74 years of age. The process of extinction of the sallow population - observed over 19 years on permanent plots and fixed trees - proceeded very quickly, especially in the first decade of observation. It led to the almost complete disappearance of sallow for the forest communities of Białowieża National Park. The death of individual trees is preceded by impairment of their health and reduced annual increments in the 4-9 last years of life. The extinction of the population is associated with the loss of its primary phenological differentiation and with a change in the sex structure of the population from a prevalence of female trees to a near even distribution of the two sexes. The development of the populations of permanent constituents of the forest (<em>Carpinus betulus</em>, <em>Tilia cordata</em>, <em>Acer platanoides</em> and <em>Ulmus glabra</em>) under the canopy of light-seeded trees, and the non-creation of a new generation of pioneer species points to the imminent end of the process of regeneration in the forest communities of Białowieża National Park.
