The climatic drought limit of common tree species depend on soil nutrient status In forest ecology, there is a huge experience in the ecological amplitude of tree species, which is commonly represented in so-called ecograms. However, the ecogram axes are purely qualitatively described and scaled. In the study presented here, we try to specify the drought limit in the ecogram for the ten most abundant and economically important tree species in Germany (Norway spruce, Scots pine, silver fir, European beech, pedunculate oak, sessile oak, sycamore maple, European elm, hornbeam and common ash) using generalized regression models. We use data on the occurrence of the tree species and on the soil of about 3300 plots of the second German forest soil condition survey (BZW II), combined with data from the ICP Forests Level I program (BioDiv and BioSoil) from 13 neighboring European countries as well as climate data from WorldClim. The focus is on the question to what extent the drought limit of the tree species depends on the soil nutrient status. As a predictor of nutrient status, we chose the base saturation type (BT) already introduced in practice. The warmth factor was included as Growing Degree Days, the water balance as climatic water balance in the forest vegetation period (KWB). The drought limit could be specified for all tree species except elm and pedunculate oak. It was found that not only in known nutrient-sensitive tree species (sycamore, ash, hornbeam), the drought limit depends on the BT, but also in beech and spruce. In the case of sycamore as an example of a nutrient-sensitive species, the dry climate limit on strongly acidic soils (BT 5) is already reached at a KWB of 20 l/m2, on base-rich (BT 1 and 0) only at a KWB of −150 l/m2. In beech, too, the drought limit on acidic soils has been reached more quickly than on base-rich sites (BT 5: −40 l/m2, BT 0: −120 l/m2). In contrast, the reaction of spruce is reversed (BT 5: −50 l/m2, BT 0: 10 l/m2). For pine, sessile oak and fir, the drought limit is independent of the base type and is −230 l/m2 (Scots pine), −150 l/m2 (sessile oak) and 0 l/m2 (silver fir). The drought limit specified by BT is a helpful quantity, especially in view of climate change, as it makes it possible to better estimate the potential of the different tree species.

The tree species diversity and population structure were studied in four stands of the tropical forests in the north-central Eastern Ghats, based on tree inventories conducted on four 1-ha plots. In the four independent plots, two 5 x 1000 m transects were established and all trees with ≥ 15 cm girth at breast height were enumerated. The density, frequency, basal area and IVI along with diversity indices viz. Shannon index, species richness, equitability and species dominance were computed to see the variation in tree community. A total of 92 species representing 73 genera under 40 families of angiosperms were recorded. Tree species richness was as low as 34 species per hectare plot in Geddapalli to as high as 48 species in Koruturu. Tree density ranged from 360 stems per hectare in plot Geddapalli to 526 stems in plot Chintapalli and that of total basal area from 16.31 m2 ha-1 in Koruturu to 31.15 m2 ha-1 in Chintapalli. The number of species and stems decreased from the smaller to the largest girth classes. The tree inventories of the study area when compared to those of the other tropical forests showed great differences in density and basal area. This may probably be due to differences in geography and annual rainfall patterns. The information on tree species structure and function can provide baseline information for conservation of the biodiversity.

Soil Nutrient Status

Mass loss and nutrient release from decomposing foliage litter of beech (Fagus sylvatica L.) and Norway spruce (Picea abies (L.) Karst.) were studied at three sites along a soil fertility gradient. The influence of soil type on initial litter quality and on decomposition was separated by reciprocal transplantation of litter among soil types using the litterbag technique. Decomposition of beech litter was influenced by both initial litter quality and incubation site. Mass loss in beech litter was positively influenced by soil nutrient status. Decomposition of Norway spruce litter was not affected by initial litter quality, and the positive influence of a nutrient-rich soil environment on decomposition was weak. Nutrient release in litters of both tree species was greatly affected by soil type through its influence on initial litter quality, as nutrient release was positively related to initial nutrient concentrations. Nutrient release was less affected through the soil environment, as it only influenced release of some nutrients, and the differences were not consistently related to soil nutrient status or mass loss. The influence of soil type on decomposition differed among the two tree species, suggesting that it may be more significant in species that produce relatively higher quality litter.
