Course abstract

The aim of the dendrology course is to acquaint with the morphological and anatomical features of woody plants, tree ecology, various life forms, reproduction, rhythm of life processes and phenology. Within the course, the woody plants growing in Latvia - apophytes (trees, shrubs, dwarf-shrubs, semi-shrubs, woody lianas), their distribution in the wild and occurrence in greenery, as well as issues of introduction, various life forms of woody plants - anthropophytes, their degree of naturalization should be learned.

Learning outcomes and their assessment

After learning the study course, student knows the woody plants growing in Latvia naturally, as well as the most often planted in greenery (laboratory work 1 - 16), is able to choose the taxonomic affiliation of each woody plant according to the leading features (tests 1 - 4), and has competence in certain taxa to be associated with growing conditions - both different forest types and growing conditions in greenery (written exam).

Description of the organization and tasks of students’ independent work

Literature studies for acquiring the issues included in the course.

Criteria for Evaluating Learning Outcomes

The final assessment of the study course depends on the assessment of the exam answers and the cumulative assessment of the study course tests.
Only those students who have successfully answered the colloquia (assessment - passed), as well as successfully written (at least grade 4) 4 tests are allowed to participate in the exam.
A student can obtain a successful mark in a test or exam if at least 50% of the questions are answered correctly.
Colloquia to be acquired within the laboratory works are successfully answered, if the student recognises, can name names in Latvian, scientific names and taxonomic affiliation of at least 95% of the requested woody plants.
