Opis:
In years 1970−2002, in Poland forest damage zones were distinguished within the framework of forest management works. Since 2003 degrees of stand damage have been determined. This study presents basic characteristics of the methods employed for these purposes concerning the necessity to elaborate a new method of determination of degrees of stand damage. The establishment of forest damage zones and degrees of stand damage cannot be treated as one of the forms of monitoring because in order to determine their range, no observations on the permanent plots and – within their confines – on the same sample trees were and are carried out. Over the time, evaluation criteria or/and ways of establishment of the extent of damages have been undergoing considerable and significant methodological changes and modifications. In terms of dynamically altering quantitative and qualitative impact of different factors affecting forest environment, 10 years period of observation repeatability is far too long to use this information as an indicator of occurring changes. In practice, it was and it still is impossible to determine objectively trends and directions of changes taking place in a given object, which is one of the objectives of forest monitoring. The concept of damage zone should be understood not only as an area of grouping the stands of the same or similar damage, but, equally importantly, as those which happen to be under the influence of the same factor exerting its influence at the same level. Therefore, when determining the range of zones, the following three actions should be taken into consideration simultaneously: complex crown evaluation, dendrometric measurements and monitoring of the effect of the causative agent. In order to trace the trends of the changes on the study plots, the same sample trees must be subjected to evaluations and measurements. From the point of view of the time perspective, examinations should be carried out every 5 years (assessment of the crown condition and dendrometric measurements) or on a continuous basis (monitoring of the effect of the causative agent) irrespective of the forest taxation. It is also advisable to consider possible use of contemporary remote sensing techniques to determine the range of zones and degrees of damage, which preliminary can be used to establish the range, intensity and kind of the damages.

Opis:
In Poland, since 1970, the impact of the industrial air contamination on forests was determined during the management work in individual forest districts. For that purpose, various methods were employed published in successive forest management instructions (1970, 1980, 1994 and 2003). Within the framework of large−area inventories, since 1983, forest health and sanitary conditions were also determined on the entire area of Poland (1983, 1985, 1988, 1991, 1999−2001, 2005−2009). The size of imissions reaching stands was assessed on the basis of the so−called technical monitoring carried out jointly by the Office of Forest Management and Forest Geodesy and Forest Research Institute. The aim of the study is to present a short historical outline as well as to review advantages and disadvantages of the applied methods and their significance for Polish forestry.

Opis:
Assessment of the impact of large herbivores on young generation of trees in the protected forests can support decisions about whether to intervene in natural ecosystems (e.g. individual tree protection, animal culling) or not. A study on the condition of forest regeneration, including the assessment of the damage caused by deer, was performed in the Gorczański National Park (GNP; southern Poland) in 1993 for the first time. The inventory was repeated in 1996 and 2011 on the same 415 concentric permanent sample plots located in the centers of 400×400 m grid. Trees with diameter <16 cm or height 1.3 m were counted. The impact of deer was assessed using: (i) the share of browsed terminal shoots in h=0.3−1.3 m class trees and the tolerable (based on a reference) share of browsed trees of such height with the most damaged tree species taken into account and (ii) the proportion between the density of recently (the previous year) debarked, frayed or broken trees and the tolerable (based on a reference) density of such trees. The main interpretation unit was composed of all stands in the GNP, while stands in particular protection districts formed lower level. Over the time, the density of trees in the regeneration layer increased (fig. 1). The density of recently debarked (frayed or broken) trees decreased considerably (fig. 2), even if a large number of trees (especially silver fir) with old wounds existed (fig. 4). The density of the browsed trees remained more or less unchanged. This type of damage most frequently affected silver fir, sycamore maple and rowan (fig. 3). Differences between the level of forest regeneration damage in different protection districts of the GNP remained similar (fig. 5). The deer impact assessed on the basis of the density of debarked trees significantly decreased to be classified as tolerable in 2011. However, the impact assessed with the share of trees with the browsed terminal shoot did not reach the tolerable level in one protection district. Results show that measures undertaken to protect forest regeneration produce a partially positive effect. The browsing level was still too high. Differences in the deer impact on the forest regeneration between protection districts can be considered as permanent ones.

Opis:
The study presents the methodological and applicative scope of mapping and assessment of forests ecosystem services within the Integrated Environmental Monitoring Programme (IEMP). The IEMP operates within the State Environmental Monitoring Programme performed under the coordination of the Chief Inspectorate for Environmental Protection. The program targeting at the ecosystem services is implemented in 11 IEMP research catchments, which are located taking into account a diversity of the landscape−ecological zones and physical−geographic regions across the country. The research, being conducted since 2015, includes: typology of ecosystems based on land use and land cover data, assessment of the potential of ecosystems to provide services using the bonitation matrix, and identification of ecosystem services indicators on the basis of the IEMP measurement programme. The results indicate that the differentiation of ecosystems mosaic between research catchments leads to a specific mixture of ecosystem services for each catchment. Regional variation of the ways and intensity of the ecosystems use by society determines the different importance of individual services. It can be concluded that the IEMP provides helpful data for recognizing the structure and value of forests ecosystem services in Poland. The vast scope of the IEMP measurement programme and diverse character of research catchments give the opportunity to investigate a broad spectrum of regulating ecosystem services. Further efforts should focus on strengthening the interpretation of the measured parameters in the context of benefits for human, and determining conditions for extrapolation of obtained values to other areas.

Opis:
More than 3000 direct observations of 5900 mooses were used to investigate the sex structure and growth of the population living in the Kampinoski National Park (KNP, central Poland). The study used data collected by the park service since 1998. To confirm the hypothesis that the random observations will accurately describe the population structure the experiment was performed with a theoretical population. It was a collection of 102 numbers (1−39 for females, 40−81 for males, and 82−102 for calves). Sex structure of this population was 1:1 and the growth rate was 0.6 calf/female. To provide the randomness all ‘animals' were mixed and renumbered. Each time we drew 4 numbers (like 4 random moose observed). The drawn numbers were grouped into: males, females and calves. Results of the consecutive draws were accumulated, while sex ratio and growth rate of this hypothetical population were constantly recalculated. Changes in ratios with increasing abundance of ‘recorded' moose were observed. It was assumed that the accuracy of estimates of population structure will increase with the number of observed animals and ultimately the results of the draw will show real sex structure and growth of analyzed population. The draw was repeated three times. Each time the results confirmed the hypothesis. A similar procedure was performed for empirical data from KNP. The documented direct observation of moose throughout the year provides a reliable assessment of the sex structure and population growth. At a constant, daily assessment of gender structure requires longer observation time than evaluation of growth. Application of these traits based on a small empirical material and/or short follow−up time may result in significant errors. The sex structure of moose in KNP is at the level of about 1:2, while growth at 0.8 calf/female. The values of indicators describing these characteristics are higher than previously adopted for the purposes of hunting of moose use in Poland. It would clarify the methodology of recording observations – a clear definition of calf age (0−1 years) and a separate listing of moose treated as an independent one−year age group. It is also strict principle of not combining several separate observations (e.g. summary of the daily observations) as one independent observation. The method of accumulation of direct observation to assess the gender structure and growth should be tested in other deer species.
