Opis:
We present a study of the distribution, ecology and conservation status of Cupressus atlantica, an endemic tree of the High Atlas (Morocco). The main populations of this species grow in a reduced area along the N’Fiss valley in the Central High Atlas and are gradually receding. Particular populations are increasingly fragmented and the total area covered by the cypress woodland has decreased to less than a third of the surface occupied in the 1930s. Overgrazing reduces the woodlands’ regenerative capacity, and the exploitation of the wood, linked to traditional uses by the rural society of the N’Fiss valley, directly reduces the number of trees. Great efforts being made to protect the species by the Haut Commissariat aux Eaux et Forêts are having some effect in recent years.

Opis:
Understanding the relationship between tree species diversity and above-ground carbon (AGC) storage in tropical forests is essential for a sustainable flow of ecosystem goods and services. Although tropical forests of Vietnam are of particular interest due to their high biodiversity and carbon density, few studies have evaluated the relative importance of species composition, tree species diversity and forest structure on AGC storage by forest vegetation type. In this study, we tested for the influence of taxonomic diversity, forest structure and species composition on AGC storage in evergreen broad-leaved and deciduous forests of Southeast Vietnam. Data was collected within 137 rectangular plots (25 m × 20 m), randomly selected across a deciduous forest (DF) and four evergreen broad-leaved forest (EB) categories, with different standing volumes levels: very poor (EBG), poor (EBP), medium (EBM) and rich (EBR). In total, we identified 3687 individuals from 110 tree species belonging to 46 families in 6.85 hectares of sampled area. AGC storage significantly differed among forest categories, ranging from 14.81 Mg ha−1 in EBG to 146.74 Mg ha−1 in EBR. There was higher AGC in the medium diameter class (20-40 cm), except for EBR where there was higher AGC within individuals of 40-60 cm in diameter. Taxonomic diversity was weakly correlated with AGC while stand structure (stem density and maximum diameter) were strongly correlated. Our results suggest that maintaining the abundance distributions of remnant tree species, particularly that of large trees, is one important method to enhance AGC storage in the tropical ecosytems of southern Vietnam.

Opis:
The urban environment is stressful and trees experience multiple stresses, including drought, flooding, and extreme heat, all of which are likely to increase under future climate warming and increasing urbanisation. In the selection of tree species to maximise ecosystem services, tolerance to site characteristics such as flooding and severe drought is of critical importance. This study evaluated the suitability of a rare species, Alnus subcordata C.A. Mey (Caucasian alder) from the Hyrcanian forests of southern Azerbaijan, for its functionality as an urban tree. A total of 48 pot-grown, two-year-old saplings of A. subcordata were tested in a greenhouse experiment using a complete randomised block design. Each block contained four replicates of three treatments (waterlogging, drought, control), with 16 plants per treatment. Height differences between treatments were measured, and water status was estimated by determination of midday leaf water potential (ΨL) and stomatal conductance (gs ). To estimate drought tolerance reaction in the treatments, leaf water potential at turgor loss (ΨP0) was used together with broken-stick modelling of water status over time. There was a significant difference in tree height between the different treatments. In the drought treatment, A. subcordata plants showed no height increase, while plants in both the waterlogged and control treatments increased in height during the nine-week experiment. Over 63 days of flooding, plant water status was slightly more negative in the waterlogging treatment, but did not deviate essentially from the control. In the drought treatment, plant water status rapidly deviated from the control. There was a significant difference in ΨP0 between treatments, with drought-treated plants showing the lowest value (−2.31 MPa). This study demonstrated that A. subcordata has limited tolerance to drought and seems to rely more on water loss-avoiding strategies. However, the species may be usable at periodically waterlogged sites, due to its high tolerance to flooding. It could therefore be recommended for wet urban environments and stormwater management facilities, for which reliable guidance on suitable trees is currently lacking.

Opis:
Indigenous mycorrhizal colonisation of one (1/0) and two (2/0) year old Scots pine (Pinus sylvestris L.) seedlings from forest nurseries situated in the north-west part of Poland was investigated. Seedlings were fertilized after a schedule designed to satisfy their requirements which resulted from soil analysis of each nursery. In autumn needle nitrogen concentration and mycorrhizal status were estimated. As a rule seedlings 1/0 obtained high doses of fertilizers, and their needle nitrogen concentration highly exceeded the recommended optimal level above which mycorrhiza formation is greatly restricted. Highly negative correlation was found between the nitrogen status of foliage and mycorrhizal quantitative and qualitative colonisation estimated in the abundance class of 0-5. When internal nitrogen level was low, several ectomycorrhizal morphotypes were found on roots of tested plants. Excessive nitrogen fertilization decreased root ramification pattern and along with increased pH promoted ectendomycorrhizal symbiosis. Two-year-old seedlings (2/0) were characterised by significantly lower nitrogen concentration in the needles which resulted in much higher ectomycorrhizal colonisation. Ectendomycorrhizal symbiosis in the case of 2/0 seedlings was scarce. The results indicate that natural colonisation in nurseries is dependent on the soil management practices, especially nitrogen fertilization. Optimalization of nitrogen fertilization may intensify ectomycorrhizal colonisation of the nursery stock from indigenous fungal species and improve the growth of Scots pine seedlings in bare-root nurseries and plantations.

Opis:
Ectomycorrhizal (ECM) fungi and their symbiotic associations with forest trees are among major drivers of key ecosystem functions such as carbon and nitrogen cycling, plant nutrient and water uptake from soil, plant-plant facilitation/competition and diversity regulation via common mycorrhizal networks. Through their functional traits and interactions with both abiotic and biotic environment, they also significantly affect the process of open land colonization by trees as well as vegetation succession coupled with soil and ecosystem development. Here we review the role of ECM fungi in the early primary and secondary succession following major anthropogenic disturbances. Based on the examples of mine spoils and post-agricultural lands, we demonstrate key ecosystem services provided by ECM fungi in the processes of forest restoration. We point out ecological mechanisms and adaptations which underpin ECM fungal community successional interactions, particularly life histories, dispersal, spatial structure, host preferences, and sensitivity to environmental filters. We emphasize the need of better understanding the role of ECM fungi in the forest restoration practice as it seems crucial for afforestation success and biodiversity rehabilitation. Thus, ectomycorrhizal traits should be a prime consideration in afforestation and carbon sequestration polices, sustainable forest management and biodiversity conservation practices.

Opis:
Two provenance experiments with Norway spruce in Slovakia were used to reveal trends in the behaviour of provenances after their transfer. Regressions between the average height and survival of provenances and the differences between the geographic and selected climatic characteristics of the place of origin and provenance plots were significant for most of the characteristics tested. Data from the experiment with Polish and Slovak provenances from 1972 indicated that transfer into warmer regions with a longer vegetation period results in improved height growth and survival, with the exception of survival at initial stages. The experiment from 1964 with a broader altitudinal range of provenance plots, but with unadjusted latest measurements at individual plots available, revealed the best height growth of Slovak Norway spruce provenances after their transfer to sites with the mean annual temperature approximately 1°C higher and with the vegetation period 12 days longer than at places of origin. Transfer into lower altitudes, a warmer climate and a longer vegetation period improved survival. In both experiments, transfer to areas with increased rainfall had a negative effect on growth, which is probably associated with the fact that provenances are not able to exploit additional precipitation for the growth in areas with a colder climate and a shorter vegetation period.

Opis:
The paper provides a detailed characterisation of Norway spruce stands in the Ukrainian Carpathians. The majority of natural spruce stands in Ukraine occur in Polesie, while artificial regeneration is spread all over the country. The most densely forested part of Ukraine is the Carpathian region with 41.1% of forest-covered area (2.1 million ha). Spruce-dominated stands occupy about 700 thousand hectares (30%) of the forested area of the state forest fund in the Ukrainian Carpathians, and another 10% of the mixed forests contain 10 to 30% of spruce. Besides pure spruce stands, there are beech-spruce, beech-fir-spruce, and cedar-spruce stands. The most productive stands (750-900m3 stem wood per ha) grow in the middle and lower parts of slopes at 1100-1200 m a.s.l. which have favourable soil and climate conditions. Since the second half of the 20th century, spruce stands in the substantial part of the Ukrainian Carpathians have declined under the influence of complex anthropogenic and natural factors. Although the present condition of most spruce forests in this region remains satisfactory, the degradation processes and the ban imposed in 2006 on planting spruce on non-spruce forest sites (in state forests) may decrease their area in the longer term.

Opis:
Over 50 populations of Norway spruce from Bavaria were analysed at 23 isozyme gene loci. The mean genetic distances between these populations were quite small. A geographical grouping could not be observed, and discrimination between provenances from high and low altitudes was not identifiable using this marker type, either. The only difference between spruce populations from South Bavaria and those from Northeast Bavaria is in the presence of some distinct rare alleles. The highest values for the genetic diversity were detected for spruce stands in Northeast Bavaria (Frankonian Forest). Using STS markers, further genes of the nuclear genome of Picea abies can be dealt with. The genetic differences found on the basis of ten STS markers between different Picea abies seed lots and/or seedling populations are generally 2-3 times greater than those found by means of isozyme gene markers. DNA markers turned out to be an appropriate and substantial addition or even more a suitable alternative to isozyme markers for analysing genetic variation and testing provenance identity. Their advantages consist in a markedly wider variation as well as in the enlarged genome segments investigated.

Opis:
The quality assessment of spruce seeds consists mainly in determining their germination capacity, including germination rate (speed), but also purity and weight. Internationally recognised methods are listed in the ISTA Rules for Seed Testing which also specify test conditions. Some countries such as Poland use modified methods. Apart from providing information about the purity of a species, purity testing can also identify the proportion of winged seeds in each seed lot. Germination tests yield data on the maximum germination potential of a seed lot which are used to compare the quality of different lots and to establish the field sowing values. This paper presents the methods used for assessing the quality of Norway spruce seeds, and discusses their advantages and disadvantages and the problems that need further investigation.

Opis:
In the last decades, clone testing has become an important component of the long-term breeding and seed orchards for Norway spruce in Sweden. For more than three decades, considerable resources have been spent on testing clones intended for clonal forestry, but the Swedish forestry never saw it worth to pay the added cost involved in the added gain. The efforts, however, resulted in many clone trials and developments in the technique for clone production and propagation. Theoretically, clone testing is faster and cheaper than progeny testing and more reliable than selecting individuals forwards. Nowadays, the main line in long-term breeding is to make crosses between the best trees and test-cloned full-sibs as a recruitment population for long-term breeding and seed orchards. Since controlled crosses are a bottleneck for long-term breeding, a possibility is to rely on wind pollination (Breeding Without Breeding; BWB) in trials for testing clones. The seed parent is known, and that the pollen parent is a desirable genotype can be checked by molecular markers. BWB has the potential to eliminate the waiting time between selection and recombination, which is particularly important in a late and irregularly flowering species such as Norway spruce. Clone testing ensures that the breeding values are known from the same tests as those used for BWB. Another option for BWB is to place in seed orchards a few ramets of clones belonging to the breeding population, but normally not deserving such a use, with the hope that their presence will make it possible to rely on wind pollination to recombine the whole breeding population.

Opis:
The abundant flowering, observed in 2004 in a model outbreeding seed orchard established in Kórnik, Poland, promoted crossing between clones of five geographically distant populations of Norway spruce. The clones were selected from a group of ca. 1100 provenances participating in the international IUFRO 1964/68 experiment and performing best in terms of growth traits and adaptability. In the seed orchard, 91.3% of clones and 64.1% of grafts produced female and/or male strobili. Statistically significant differences between the clones were only found in the number of mature cones produced. The mean number of mature cones in individual clones was also significantly correlated with the latitude of the place of origin of maternal populations (r = 0.88, p = 0.047). The nearly equal percentages of clones representing each of the five populations in the outbreeding seed orchard (from 23.2 to 17.5%) resulted finally in the highly unequal production of full seeds by each population (from 62.9 to 0.7%). These data provide evidence to suggest that the level of genetic diversity in the progeny, expected from the number of growing clones, diverges from the level resulting from the contribution of clones to the full seed production which is an effective measure of the genetic composition of progeny. To avoid this divergence, an outbreeding seed orchard could be established with unequal proportions of clones from different provenances, considering the knowledge of their flowering phenology, and individual variation in flowering and cone production.

Opis:
At present, Norway spruce stands occupy 22% of the total forest area in Lithuania. Most of them are located in the northeastern highland (Žemaitija) and the central part of the country. 25% of the spruce-dominated stands are pure, the rest are mixed. Natural calamities like storms, droughts, and pests cause substantial damage and occur quite frequently. About 40 thousand ha of stands are cut after each storm. The mean wood yield of the spruce stands is 304 m3 ha-1, and the current annual increment is 6.2 m3 ha-1. The climatic conditions of Lithuania are variable enough to cause differentiation of habitats. For Norway spruce, 6 provenance regions have been established. The national gene conservation programme is based on (a) in situ genetic reserves, seed collection stands, and selected genotypes, and (b) ex situ clonal archives, seed orchards, experimental plantations, and gene bank collections. The present-day breeding of Norway spruce comprises family tests of populations for individual and population selection, and plans for inter-population hybrids. A strategy for Norway spruce breeding has been approved for the years 2004-2013. There is a genetically diverse material for future breeding: long-distance provenance tests, and population and family tests. Assessments of two provenance tests (aged 9 and 17 years) in central Lithuania revealed superior performance of central and northeastern Polish provenances: superior height, good stem quality, and late bud-burst in spring. This may be attributed to the favourable effect of transfer: avoidance of spring frosts (late bud-burst and good stem quality), and utilisation of the later part of the growing period for growth (late bud-set and superior height). Norway spruce is a climax species with different domestic and Darwinian fitness. Therefore, we suggest that the domestic fitness of local genotypes may be improved by introducing a few Polish clones in Lithuanian breeding populations.

Opis:
In connection with the decline of spruce stands on the Krynica plots of IPTNS-IUFRO 1964/68, observed in the last decade and attributed to the so-called spiral disease, an attempt was made to determine whether the current health condition of trees is influenced by genotype (provenance). As shown by preliminary observations, the spruces differed in the degree of survival depending on provenance. The inventories of died or broken trees to be removed during the sanitary cutting, made in the years 2000, 2003, 2004 and 2008, yielded also information about the number of spruces that remained in the blocks of the experiment for each provenance and provenance region by Krutzsch (1968). Analysis of variance showed that genotype (provenance) has a statistically significant effect on the survival of trees. In the years 1999-2008, spruces from region 21 (Bohemian Forest) displayed the poorest survival rate in the conditions of the Beskid Sądecki Mts., while those from region 80 (Eastern Siberia) survived best.
