Amorpha fruticosa L. on wet sites in Belgrade

Abstract

Amorpha fruticosa is in many countries, and also in Serbia, one of the most dangerous invasive species. The detection of mechanisms which inhibit the spreading of Amorpha population would be of great significance for finding the adequate measures of biological control. In this sense, first of all it is necessary, inter alia, to determine Amorpha ecological and coenological characteristics. The vegetation studies of wet sites in Belgrade were compared. The study results indicate that Amorpha is present in forest communities, from the lowest elevations at the timber line to the highest elevations, where the periods of underground and flood waters are the shortest, or where they are absent. Amorpha forms thick brushland on meadows with different water regimes and in forest plantations of different canopy closure. If it is regularly removed by felling, Amorpha does not endanger the structure and the floristic diversity of meadow communities. Amorpha is absent or rare in forest plantations of the densest canopy, as well as in the communities which belong, or once belonged, to the alliance Magnocaricion Br.-Bl

Floristic diversity, composition and invasibility of riparian habitats with Amorpha fruticosa : A case study from Belgrade (Southeast Europe)

“…Nevertheless, the species Carex hirta, Mentha aquatica, Poa pratensis, Poa trivialis, Potentilla reptans, Ranunculus repens, Stachys palustris and others, which occurred with significant contribution in both groups of stands (C and G) indicated that part of these stands probably originated from the lowland meadow communities that could be classified in the alliance Trifolion resupinati K. Micevski 1957 of the order Trifolio-Hordeetalia H-ić 1963. Similar observation was published by Radulović et al (2008), who reported that A. fruticosa builds large populations in meadows of the alliances Agropyro-Rumicion crispi and Trifolion resupinati, regardless of their differences in terms of the impact of flood and ground water. Furthermore, these authors pointed out that A. fruticosa was absent from the communities of the alliance Magnocaricion Br.-Bl, suggesting that further investigation is needed in order to find whether Carex spp.…”

“…As it can reproduce both generatively and vegetatively, it is growing faster than most forest-cultural species (Tucović and Isajev, 2000;Gagić-Serdar et al, 2013). Amorpha fruticosa aggressively penetrates into newly invaded sites, where it establishes permanently (Radulović et al, 2008).…”

Isolation and seasonal variation of fruticin in fruits of false indigo-bush (Amorpha fruticosa L. Fabaceae) from Serbia

“…As a heliophilic plant, it competes for the light and forms dense thickets that overshadow and suffocate the native flora, changing successional patterns and reducing biodiversity (Kozuharova et al, 2017;Krpan et al, 2011;Szigetvári, 2002). It is also widespread in Serbia, especially in Vojvodina, Mačva, and wider Belgrade area (Lazarević et al, 2012;Radulović et al, 2008). Bearing in mind the damage that this plant causes not only to floristic diversity and forestry, but also to water management, drainage systems, roads etc., its presence should be reduced, or con-trolled by any cost.…”
