“…There is a need to detect the critical N loads for mycorrhizal communities in European forests above which communities suffer changes that can affect forest ecosystem processes, as previously reported for forests in North America (Pardo et al 2011) and oak forests in Europe (Bobbink and Hettelingh 2011;Suz et al 2014). These thresholds may be similar to other taxa such as vascular plants that also demonstrate a sensitive response to N loading and changes in soil pH (Ikauniece et al 2013). Simultaneously, we need to identify species and sets of species that can indicate and predict ecosystem condition and vice versa (e.g.…”

“…Field sampling was conducted in 2015 to 2016 (26 plots) and we included data (24 plots) from another study (Ikauniece et al 2013) that employed the same methods, but G. Brūmelis, S. Ikauniece, A. Voiceščuka, A. Artistova, A. Treimane, I. Dauškane, D. Elferts, D. Tjarve which was focused on understory herbaceous communities of oak stands. Forest stands were randomly selected from the Forest Register of Latvia (State Forest Service) from as much as possible all regions of Latvia based on the following criteria: broad-leaved tree species contributing at least 70% of total stand composition by wood volume, stand area > 1 ha, age > 60 years.…”

In Latvia, the noble broad-leaved tree species woodland with pedunculate oak (Quercus robur L.), small-leaved lime (Tilia cordata Mill.), Norway maple (Acer platanoides L.), wych elm (Ulmus glabra Huds.), white elm (Ulmus laevis Pall.) and common ash (Fraxinus excelsior L.) has decreased to about 1% due to the historical legacy of wood extraction and conversion of fertile soil to agricultural land-use. The aim of the current study was to determine the tree age structure in the canopy and size structure in the shrub layer of broad-leaved tree stands to determine past changes and to predict future trends in tree species composition in the context of potential management methods. In 50 randomly selected broad-leaved tree stands, plots of size 0.1 ha were established. In the plots, diameter at breast height was measured for all trees with diameter >10 cm and cores were removed from all of these trees. All other stems were counted by species in height classes ≤ 1 m, 1.1 to 5 m, 5 to 10 m. The stands were classified into 10 groups based on canopy composition in age classes. Norway spruce [Picea abies (L.) H. Karst.] was common in various tree layers of in many of the groups, and it is recommended that it should be removed during stand tending. Q. robur regeneration should be promoted in specific cases where abundant in the < 1 m layer and where large gaps can be created. T. cordata is commonly present in several tree layers and its growth could be promoted by thinning of P. abies where present. Abundant Q. robur regeneration is sometimes found in Scots pine (Pinus sylvestris L.) stands.

This study used the normalized difference vegetation index (NDVI), in conjunction with other ancillary indices, a digital elevation model (DEM), and the multistep unsupervised classification method to classify grassland in Gansu Province and the Qilian Mountains in China. The results showed that the overall accuracy of vegetation type reached 88.79% and that of grassland coverage level reached 87.23%. The ancillary indices suitability analysis revealed that meadow was distributed mainly in zones where the normalized difference moisture index (NDMI) varied between −0.64 and −0.4, whereas for steppe, it varied between −0.55 and −0.32. Grassland with a different coverage level was mainly distributed in zones where the normalized difference soil index (NDSI) varied between −0.20 and 0.25. To demonstrate the usability of these two indices, the maximum values of NDVI, NDMI, and NDSI and the DEM were used in the decision tree classification method for grassland. The results achieved relatively high kappa coefficients of 77.09% for vegetation type and 65.29% for grassland coverage level. Based on these results, it can be concluded that it is rational to apply the multistep unsupervised classification method and the selected indices for regional-scale grassland identification when a priori information is scarce, expensive, or unsuitable.
