Opis:
The natural consequences of introducing alien species can be significant. This is particularly a concern where the taxa have an invasive nature of spreading or in those that freely crossbreed with native species. The hybridization process may lead to impoverishment or even loss of the native gene pool. This is especially dangerous in unique areas that stand out due to their special natural characteristics, such as the Tatra National Park. The determination of the scale of occurrence of alien larch species in the national park and the evaluation of the genetic diversity of the native population is crucial for the conservation of genetic resources and strictly adheres to the latest conservation genetics trends. We evaluated the possibility of effective use of molecular markers for taxonomic identification of the native European larch (Larix decidua Mill.), as well as the alien Japanese larch (Larix kaempferi [Lambert] Carriere) and the hybrid form (Larix × eurolepis Henry). Microsatellite markers were used to analyse the genetic di- versity of individuals identified as European larch from natural refuges and artificial plantings. Of the 148 trees analysed, 105 were identified as the European larch, 38 as Japanese larch, and five as hy- brids. The analysis of the molecular variability of two European larch groups of indigenous and artificial origin showed comparable level of diversity. This study confirmed the effectiveness of the use of selected molecular markers in identification of larch species, which is difficult based on morphological traits. The results indicate the possibility for the effective use of genetic tools in the creation of protection programmes, especially for naturally valuable sites, based on genetic taxonomic identification and richness verification of protected gene pools.

Opis:
It is commonly known that Japanese larch, Larix kaempferi was first introduced in Europe in Great Britain in 1861. In the presence of European larches, L. decidua it was not long before the first hybrids between these species, called Dunkeld larches (Larix × marschlinsii), emerged there. It was found that there were several hybrid larch trees in Estonia that sprouted before one of their parent species was introduced in Europe. One of the oldest Dunkeld larches growing in Tallinn is about 210 years old. The radial growth of three Dunkeld larches in Estonia (in the cities of Pärnu and Tallinn and in the manor park of Suure-Kambja) and the determination of their age by cumulative growth graphs are discussed, with consideration given to the available knowledge on the introduction of Japanese larch. The conclusion is that there may have existed earlier alternative introduction routes of Japanese larch into northern Europe via Russia.

Opis:
The quality of 39 Japanese larch stands, mainly in north-western Poland, was characterized. On the basis of the presented results it can be concluded that properly managed forest stands of Japanese larch can compete in trees quality with stands of native larches. The alien species is more susceptible to a lower stand density and exposure to strong winds. This is no correlation between forest stand quality and growth dynamics.

Opis:
Japanese larch (Larix kaempferi Sarg.) is one of the most frequent exotic species in Polish woodlands. The basic object of research comprised 60 stands of the studied species, located mainly in the northern and western parts of Poland. The growth results for the studied species, evaluated on the basis of the average height (hg55), were compared with data describing the local climate and the stand location within the botanical and climatic zoning. The results confirm the opinion that the Japanese larch prefers a climate of maritime character and generally shows high degree of flexibility regarding its climatic requirements (very large differences between the growth conditions in the studied area and the country of origin). The dependence between the growth results and precipitation is however lower than expected. The most interesting results include the relatively clear connection between the height of the larch stands and the Degórski’s (1984) ‘floristic’ ‘K’ (continentality) index.

Opis:
This study compared soil CO2 efflux rates in three adjacent coniferous plantations consisting of larch (Larix leptolepis Gordon), red pine (Pinus densiflora S. et Z.) and rigitaeda pine (P. rigitaeda: P. rigida Mill × P. taeda L.) species planted in the same year (1963). Soil CO2 efflux, litter fall carbon (C) and root decomposition rates were measured with soil environmental factors for two years. The mean annual soil CO2 efflux rates (g CO2 m−2 hour−1) were the highest in rigitaeda pine (0.30), followed by red pine (0.27) and larch (0.24) plantations. An exponential regression of the CO2 efflux rates against their corresponding soil temperatures showed a significant (P < 0.05) relationship (red pine R2 = 0.69; rigitaeda pine R2 = 0.67; larch R2 = 0.63). The soil CO2 efflux rates were negatively correlated with soil pH, but the soil water and soil organic C content were not significantly correlated with the CO2 efflux rates. Soil CO2-C efflux rates were correlated by litter fall C inputs in the larch and red pine plantations, and the decomposition rates of 5–10 mm diameter roots in the larch plantation. This result is useful in understanding potential responses of soil CO2 efflux rates with changes in stand and soil environmental factors induced by different tree species.
