Scotch broom (Cytisus scoparius) and European gorse (Ulex europaeus) are recognised invasive plants in many countries. Both species have been recorded in South Africa since 1930’s.
The new studies characterised the known and newly identified populations of both species in terms of demographics and reproductive potential.
Individual plants were counted and growth parameters were measured. Flowering, fruiting and seed set timing was recorded and measures of reproductive capacity were based on seed set, seed bank load and germinability.
Population of these species were found along roadsides and in natural and commercial forests.
