“…The similarity of the values of biomass mean annual increment (MAI) in gorsedominated communities in the sample plots of this study with those reported for native Western Europe stands [154] seems consistent with similar climatic conditions and history of land use and disturbance in those habitats [155]. However, data reported by Carswell et al [49] for this species in treeless stands in New Zealand show high growth maintained even beyond 15 years, which could be related to a niche shift, or simply due to the short time interval explored.…”

Compatible model systems were developed for estimating fuel load dynamics in Ulex europaeus (gorse) and in Erica australis (Spanish heath) dominated shrub communities at stand level. The models were based on intensive, detailed destructive field sampling and were fitted simultaneously to fulfill the additivity principle. The models enable, for the first time, estimation of the biomass dynamics of the total shrub layer, size fractions and vegetative stage, with reasonably good accuracy. The approach used addresses the high variability in shrub biomass estimates by using a site index (SI) based on biomass levels at a reference age of 10 years. Analysis of the effect of climatic variables on site index confirmed the preference of gorse for mild temperatures and the ability of high heath communities to tolerate a wider range of temperatures. In the gorse communities, SI tended to increase as summer rainfall and the mean temperature of the coldest month increased. However, in the heath communities, no relationships were observed between SI and any of the climatic variables analyzed. The study findings may be useful for assessing and monitoring fuel hazards, updating fuel mapping, planning and implementing fuel reduction treatments and predicting fire behavior, among other important ecological and biomass use-related applications.

“…Common gorse has an annual rate of 100–200 kg ha −1 nitrogen accumulation during the rapid dry-matter accumulation period (Galappaththi et al ., 2022). In fact, U. europaeus has traditionally been used as a natural agricultural fertilizer due to its nutritive effect (Atlan et al ., 2015). Soil nitrogen not only favor plant growth, but also plant germination (Duermeyer et al ., 2018), which can explain the small negative effects or the absence of them that we found on the germination of the target species exposed to U. europaeus mulch.…”

“…Mulch for the experiments was prepared using dried branches, thorny twigs and phyllodes from U. europaeus , that were cut in fractions (c.a. 2 cm) to simulate the crushing or chopping process traditionally carried out by an electric fodder cutter after U. europaeus remotion for agricultural application (Jamil et al ., 2009; Atlan et al ., 2015; Khan et al ., 2016). Also, as a spiny shrub, U. europaeus would be difficult to farmers to handle if it is not cut.…”

Invasive species control management involves a large amount of plant material. The present work evaluated the allelopathic potential of the invasive species Ulex europaeus L. (Fabaceae) or ‘Gorse’ and its possible use as a bioherbicide, taking advantage of the extracted plant material after control measures, particularly needed in invaded areas. Specifically, we investigated the efficacy of dried plant material from U. europaeus in the control of the adventitious plants, Lolium multiflorum Lam. and Lolium rigidum Gaud., using the Avena sativa L. crop as a case study. We only used vegetative plant parts because it is essential to avoid the dispersion of U. europaeus with its use, especially in invaded areas. A greenhouse pot experiment was conducted, using activated carbon (AC). The target species (L. multiflorum, L. rigidum and A. sativa) were subjected to a mixture of organic substrate with U. europaeus mulch applied pre-emergence and a subsequent application of aqueous extracts from the mulch. Emergence, height and biomass of the target species were determined. After 2 months, we also tested a possible legacy effect of the substrate on the germination of the target species. We noticed a negative effect of U. europaeus mulch on the emergence of L. rigidum, which can be attributable to the allelopathic compounds released from U. europaeus mulch because the effect was non-significant in presence of AC. Conversely, no effect on L. multiflorum or A. sativa was produced by mulch treatments. Nevertheless, the combination of U. europaeus mulch and its extracts demonstrated a phytotoxic effect on the biomass of the crop species A. sativa, and a fertilizing effect on the weeds L. multiflorum and L. rigidum, which is why this use is discouraged. With our results we cannot recommend the use of U. europaeus as a bioherbicide in oat crops, but this study emphasizes the capability of U. europaeus to structure plant communities through the chemic- and bio-properties of its tissues that modifies the soil environment.

Aims. The study of the adaptive potential of the germination patterns of invading species enables us to identify some traits linked with their capacity to colonize new sites, and to better understand their area of distribution. The aim of the present study is to determine the germination pattern of Ulex europaeus, a cosmopolitan invasive species, in relation to temperature and to explore its potential evolution in a tropical invaded region since its introduction from Europe. Methods. We studied the germination pattern of U. europaeus (the common gorse) to test both physical dormancy and germination capacity within the range of temperatures found in the native and invasive regions. To comprehend its germination pattern and its evolution, the rate and the speed of germination, as well as the percentage of seeds that mold during the experiment, have been compared between a native habitat, France and a habitat to which it has been introduced, the tropical island of La Reunion. Important findings. The results show that the gorse seeds possess a very high power of germination, the ability to germinate under a wide range of temperatures and confirm the physical dormancy of the seeds (caused by seed coat impermeability).The decrease in germination from 25ºC upwards, coupled with an increase in the rate of moulding help to explain its restricted distribution at altitude in tropical environments. For scarified seeds, we have not detected any difference between the two regions, neither in the percentage of germinated seeds, nor in the percentage of mould seeds. However, seeds from Réunion germinate faster at 20ºC than seeds from France. For unscarified seeds … and a greater number of seeds from Réunion are able to germinate without scarification (10-60 % for Reunion vs 0-10 % for France). These results suggest that whilst preserving the advantages of the native habitat, in Réunion gorse develops a strategy which favours the rapid occupation of new sites.
