Abstract
The article presents the results of studying the age structure of populations of J. deltoides and J. excelsa growing in the Crimean Mountains. The age of J. deltoides stands varies from 70 to 200 years (average age is 137 years). The population of J. deltoides can be characterized as being of different ages, predominantly represented by pregenerative and generative individuals, which reflects the early entry into the generative phase. The predominant age class in J. deltoides stands are middle-aged individuals, accounting for 43%. The average age of J. excelsa stands within the population varies from 137 to 500 years. The overwhelming number of J. excelsa individuals are overmature (51%). There are trees aged 900 years. A characteristic feature of the age structure of tall juniper tree stands is a certain cyclicity, in other words, population waves. On average, the interval between population waves is 130—150 years. This cyclicity is caused by peaks of seed regeneration and correlates with the maximum reproductive activity of most of the individuals in the tree stand.
Key words
Juniperus excelsa M.-Bieb., Juniperus deltoides R. P. Аdams, age structure, population waves, cyclicity, environmental factors, the Crimean Mountains.
