Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Studying the invasive flora of regions is an important task for preserving biological diversity and monitoring the possible further spread of these taxa. The aim of this study was to compile a list of invasive vascular plant species in the Karaganda region and to characterize them according to their distribution, degree and mode of introduction, and degree of naturalization in this region. The results of the study showed that 112 invasive species from 91 genera and 36 families were identified in the region. In terms of the time of introduction, neophytes predominate in the Karaganda Region—97 species, or 86.6%. Archeophytes account for a smaller share—15 taxa (13.4%). By mode of introduction, the following were identified: ergasiophytes (53 species, or 47.3%), xenophytes (54 species, or 48.2%), and acoluthophytes (5 species, or 4.5%). Based on naturalization mode, the following were identified: epicophytes (47 species or 42.0%), ephemerophytes (26 species or 23.2%), agrioophytes (27 species or 24.1%), and colonophytes (12 species or 10.7%). In terms of distribution, invasive species were classified as follows: occasional – 34 taxa (30.35%); common – 44 taxa (39.28%); very rare – 14 taxa (12.50%); rare – 19 taxa (16.96%). The data obtained reflect active migration processes involving the dispersal of seeds of invasive species and their gradual integration into local plant communities. The active naturalization and prevalence of many taxa require constant monitoring and the development of programs to curb their further spread in the Karaganda region.
