Successional Stages

The secondary birch and aspen forests of middle stages of succession of the central elevated part of the Southern Urals are studied. 4 subassociations, 1 community, and 7 variants in the alliances of Aconito-Piceion and Piceion excelsae are allocated. It is shown that the floristic composition of aspen and birch secondary forests in the age of 60—80 years is almost identical to the natural forests. However, a slight increase the coenotical role of light-requiring species of grasslands and hemiboreal forests in the secondary communities of the class Brachypodio-Betuletea was noticed as well as some reduction of role the shade-tolerant species of nemoral complex and species of boreal forests of the class Vaccinio-Piceetea. Dominant tree layer under the canopy of secondary series is marked by an active growth of natural tree species.

High Tree Density

The inventory and the analysis of the woody species preserved in the different categories of cocoa and coffee plantations showed that they are relatively diversified (presence of endemic, rare and threatened species). They also preserved high tree density and high basal areas. The young plantations are especially diversified. Their number of species,density and basal areas and diversity index are similar to those of the neighbouring old growth and secondary forests. Older plantations display a sharp decline of diversity over time. Agricultural practices in the region represent a threat in the medium term to the preservation of biodiversity.
