In this paper we present results of the botanical research performed from
October, 2022 to October, 2023 in SNR ?Titelski breg?. The Reserve has been
legally protected from 2009 and ever since, active conservation measures,
including mowing, grazing and removal of invasive plant species, have been
implemented. Titelski breg is an isolated ellipsoid loess hill situated in
the northern Serbia, between the Tisa River and several settlements. Flora
and vegetation of the hill have been thoroughly studied in the past since
1896, and most of the data were published in the period 1980-1990. Our
botanical research was conducted at 11 localities, which were previously
prioritized, based on the number of published data on vasular plants and
answers given by managers of the Reserve in the questionnaire. The
collected plant samples were preserved, identified and stored in the
herbarium of the University of Novi Sad (BUNS). After that, data on vascular
plants were compared with a database compiled with available and relevant
floristic and phytocoenological literature published between 1972 and 2022.
As a result, there were 18 new vascular plant species, five new subspecies
and one new variety. These results contribute to the general knowledge on
their distribution and floristic diversity of Serbia, and are crucial for
the evaluation of the protection and management in the Reserve.
