“…Finally, the unexpectedly high population survival of a few endangered species in green areas or built-up areas suggests unexploited opportunities to re-introduce some pre-selected species to public greenspaces (Klaus, 2013;Pan et al, 2019). In summary, our study supports a wide range of conservation approaches within and outside protected areas in cities that cover natural and anthropogenic ecosystem types.…”

“…ex situ conservation program and complement in situ conservation carried out in nature reserves. There are examples of plants threatened with extinction introduced into the urban environment, for examples, Mosla hangchowensis [ 52 ] or Calycanthus chinensis [ 53 ]. Another interesting example is the population of the rare plant Sternbergia colchicifora found along a busy road section in the downtown of the county seat Veszprém (Hungary).…”

The growing trend of introducing wild plant species into urban environments necessitates the identification of novel species adapted to prevailing conditions. A promising reservoir of such species may be xerothermic communities where Ranunculus illyricus occurs. This study aimed to establish a micropropagation protocol for R. illyricus using indirect organogenesis. The protocol includes initiation of culture from various explants, callus proliferation, shoot regeneration, multiplication, and concurrent rooting. Callus appeared on most types of vegetative explants tested, but stolons were considered the best due to their good availability, high disinfection (85%), and robust callus production (maximum increase − 363.1%). The growth rate of the callus fresh matter (CFM) obtained from stolons was calculated. Greater CFM was obtained on the medium with the supplemented picloram 8.0 mg L− 1 with kinetin 5.0 mg L− 1 and in second part of experiment on medium with the addition of 2,4-D (2,4-dichlorophenoxyacetic acid) 2.0 mg L− 1 alone or picloram 6.0 mg L− 1 with kinetin 8.0 mg L− 1. Shoot organogenesis was observed on macronutrients B5 (Gamborg medium), micronutrients MS (Murashige and Skoog) medium with the addition of 2.0 mg L− 1 IBA (indole-3-butyric acid) and 4.0 mg L− 1 BAP (6-benzylaminopurine). To document the process of callus differentiation, microscopic preparations were prepared. Subsequently, the regenerated plants underwent acclimatisation and their growth in an ex situ collection was monitored over three growing seasons. In particular, in vitro-origin plants exhibited developmental patterns similar to those of their seed-origin counterparts. The incorporation of R. illyricus into urban landscapes not only increases aesthetic appeal, but also ensures the preservation of valuable genetic resources for this rare species, potentially contributing to effective ex situ conservation in the future. This marks the first scientific report on in vitro cultures of R. illyricus.

“…Numerous studies have also shown that selection of indigenous species and suitable site identification for planting are the key question for urban landscape designers (Gotoh and Yokota 2009;Gilroy et al 2017;Backstrom et al 2018). Studies also indicated that selecting and cultivating threatened plants in urban environments contribute towards conservation and help to restore the decline of indigenous species in urban landscapes (DeCandido et al 2007;Pan et al 2019).…”

Background We evaluated site suitability, early survival, and growth performance forJuniperus procera,Olea europaeasubsp.cuspidata,Vachellia abyssinica,Hagenia abyssinica, andAfrocarpus falcatusin the urban landscape of Addis Ababa, Ethiopia. Methods The MaxEnt model was used to evaluate site suitability for the 5 indigenous species. For the early survival study, experimental plots were established and 500 seedlings, 100 seedlings for each species, were planted on 2021 July 15 and monitored until 2022 February 30 for a total of 225 days. Silvicultural activities such as mulching, weeding, and watering were conducted. Every 45 days, measurements of height, root collar diameter (RCD), death, damage, wilting, and defoliation were recorded. Results The result of the study indicated that the Addis Ababa area is well to moderately suitable to grow the 5 species. Mean survival rates marginally declined over the course of 225 days, from 99.6% at 45 days after planting to 90.4% at 225 days after planting. EighteenV. abyssinicaseedlings were found to be dead. Wild animals browsed and damaged 45% ofO. europaeaseedlings.H. abyssinicahad the highest growth performance. The study shows that, relative to the other 4 species,V abyssinicahad a greater number of wilted, defoliated, and dead seedlings. Conclusion Each of the 5 species had a high rate of early survival and found the urban environment to be suitable. This result will assist in the shift away from planting only exotic tree species in green spaces and encourage the presence of indigenous tree species.
