Description

‘Tree – tree’ interactions are important structuring mechanisms for forest community dynamics. Forest management takes advantage of competition effects on tree growth by removing or retaining trees to achieve management goals. Both competition and silviculture have thus a strong effect on density and distribution of tree related microhabitats (TreMs) which are key features for forest taxa at the stand scale (e.g. Bouget et al. 2013, 2014). In particular, spatially explicit data to understand patterns and mechanisms of TreM formation in forest stands are rare. To train and eventually improve decision making capacities related to the integration of biodiversity aspects into forest management to date more than 100 usually 1 ha (100 m x 100m) permanent plots were established in different forest communities of Europe. Due to their demonstration character the selection of plots was non-systematic. They do, however, cover a broad range of forest types (e.g. beech-oak, beech-fir (-spruce), oak-hornbeam, pine-spruce, etc.), altitudinal gradients (from 25 m – 1850 m) and site conditions (e.g. oligotrophic Luzulo-Fagetum or Vaccinio-Pinetum to mesotrophic Galio-Fagetum or Milio-Fagetum). For each plot the following data is collected: (1) tree location as polar coordinates (stem base map), (2) tree species, (3) forest mensuration data (dbh in [cm], tree height in [m]), (4) tree related microhabitats (TreMs) and (5) tree status (living or standing dead). In addition to the spatial dendrometric data we provide information on plot establishment, forest type, plot location (state, region, country), elevation, means for annual precipitation and temperature, and the natural forest community (Kraus et al., 2018).

Purpose

The demonstration plots were/are being established in the course of the projects Integrate+, Informar and FoReSite. Focus is given on showing good practice examples of integrative forest management concepts. The plots are designed following the marteloscope approach which allows to perform virtual tree selection exercises based on different scenarios and forest management strategies. Immediate feedback on decisions is given in terms of ecological and economic impacts with the help of a software that runs on hand held devises. Particular attention is given to tree related microhabitats as these structures are home to many, also endangered species. Retaining and restoring such habitats in managed forests can be well integrated into the work portfolio of forest managers and thus be a direct contribution to biodiversity conservation in managed forests. TreM recording and the development of the tree microhabitat field catalogue aims at providing individual habitat values for each tree to make harvesting impacts visible in the course of training exercises (Krumm et al, 2019). The plots and the corresponding data themselves proved also a valuable resource for different research questions. In particular, the database with the spatially explicit information on trees and TreMs can support e.g. our understanding of TreM formation and development and their spatial distribution.

Sampling Description

Study Extent

Plots were established based on interest to participate resulting in now more than 100 plots. They are mainly located in public and community forests, but also in forests owned by the church or private owners. They were selected by the forest owners based on either site availability or representing a particular forest management type (no systematic selection). Also the number of plots differs widely between countries e.g. from one to more than 35.

Sampling

Tree location: polar coordinates Tree species: scientific name (Note: tree species was also recorded for standing dead trees as far as possible; in the case of late decay stages or stands with a wide variety of trees species this was not done. The tree species was then recorded as “0”). Diameter breast height (dbh): in [cm] at 1.3 meters height Tree height: in [m] Tree related microhabitats: 64 saproxylic and epixylic tree related microhabitat types are defined and described in detail within a hierarchical structure (published as a field guide; see: quality control for reference).

Quality Control

Set-up of Marteloscope and data collection: Schuck, A., Krumm, F., Kraus, D., 2015. Integrate+ Marteloscopes - Description of parameters and assessment procedures. Integrate+ Technical Paper No. 18. 16 p. Tree related microhabitat assessment field guide: Kraus, D., Bütler, R., Krumm, F., Lachat, T., Larrieu, L., Mergner, U., Paillet, Y., Rydkvist, T., Schuck, A., and Winter, S., 2016. Catalogue of tree microhabitats – Reference field list. Integrate+ Technical Paper 13. 16 p. The catalogue of tree microhabitats is available in 17 languages: Czech, Danish, Dutch, English, Farsi, Finnish, French, German, Hungarian, Italian, North Macedonian, Portuguese, Romanian, Slovenian, Spanish, Turkish and Ukrainian (http://iplus.efi.int/documentation.html)

Method steps

  1. Plot selection: The permanent plots are selected non-systematically based on criteria, such as representative silvicultural systems for a region, accessibility or the availability of TreMs. Further plot selection was limited also by availability of forest stands which could ensure that tree removals would not take place within the next 5 to 10 years. Plot establishment: The plots are usually 1 hectare in size (100 m x 100 m) and of rectangular shape. Some of them, however, deviate in size and outline due to local site conditions, availability of resources or high tree numbers. Our standard approach is to divide the plot into 4 quadrants to facilitate orientation and the use of data subsets. All corners and centre points (incl. the centre points of each quadrant) are permanently marked. All trees with more than 7 cm diameter measured at breast height (dbh 1.30 m) are recorded and numbered. Data collection: All standing living and dead trees are recorded above a dbh of 7 cm. So is the species, spatial position, tree height and crown base height and the abundance of TreMs. Height measurements can e.g. be conducted with a digital hypsometer (VERTEX IV, Haglöf, Sweden), dbh usually with a measuring tape. Tree locations are determined e.g. by using a compass and the distance function of the Vertex digital hypsometer as a standard. In some plots the measurements were/are carried out using a specialized inventory software (Fieldmap, Czech Republic). In other plots tree coordinates were recorded using a GPS Trimble Geo7x. Note that a few trees with a dbh above 7 cm miss coordinates. They are still made available in this dataset to ensure completeness of all trees in the plots. Coordinates for those trees are labelled N/A. TreM recording in the field is based on the catalogue of tree microhabitats (see also quality control).

Additional info

In addition to the information provided in this dataset the following data are collected in the plots. Crown base height (cbh) in [m]. Further a visual assessment of timber quality classes is performed in order to be able to provide rough estimates of a trees' economic value (market price). Timber quality classes used are ‘veneer' (A - quality); ‘sawnwood’ (B - quality), ‘sawnwood’ (C – quality), ‘industrial timber’ (IT or D - quality) and ‘fuelwood’ / ‘energy wood’ (F – quality). The volume of each section is calculated based on standard calculation methods differentiated by tree species (form indices or specific tapering values are applied). Timber market prices for each quality class are provided by local forest managers at the time of data collection. As timber market prices fluctuate the economic value of a tree (in local currencies) represents only a rough indicator. In a few plots spatial information on coarse woody debris (diameter above 10 cm at the smaller end) was collected. Snags and standing deadwood are included in the main dataset but stumps and downed logs were measured only in these selected plots. For both stumps and logs the following information was recorded: (1) object (stump, log, root plate, crown); (2) polar coordinates plus orientation for logs (azimuth); (3) height and diameter (for stumps) or diameters at both ends (d1, d2) and length in [m] (for logs); (4) decay class and (5) actual tree species or if not possible conifers/broadleaves.
