Los parques urbanos son sitios de recreación, descanso, y a su vez son áreas de conservación de especies nativas. El objetivo de este estudio fue identificar las especies vegetales de ocho parques urbanos de Tegucigalpa y Comayagüela del Departamento de Francisco Morazán (Honduras), en el 2015 y 2022. Se reportaron 102 especies en los parques urbanos, pertenecientes a 43 familias y 86 géneros. Las familias con mayor número de especies fueron Fabaceae, Asparagaceae, Arecaceae, Euphorbiaceae, Apocynaceae, Bignoniaceae, Myrtaceae y Rutaceae. Los árboles son los más frecuentes (48%), seguido de arbustos (28%) y hierbas (24.5%), de estos 56.8% son introducidos y 43.2% nativos. Entre las especies registradas, Coffea arabica L. y Swietenia humilis Zucc. se encuentran catalogadas como en peligro de extinción según las Lista Roja de la UICN, mientras que en estado vulnerable están Cedrela odorata L., Araucaria heterophylla (Salisb.) Franco y Jacaranda mimosifolia D. Don y 38 especies en preocupación menor. Las actividades antrópicas como la destrucción, modificación, contaminación ambiental y falta de mantenimiento han conllevado a la pérdida de vegetación nativas en estos parques urbanos. Una propuesta de reintroducción de especies nativas es una alternativa para evitar la introducción de plantas que puede traer consigo la incorporación de especies invasoras.

“…As well seen, particularly in Tumaco, Colombia, activities such as illegal mining, illegal coca cultivation, expansion of oil palm plantations, intensive agricultural practices, and indiscriminate logging (Lopez-Soler, 2021), have resulted in the deterioration of conservation areas, such as mangroves, due to occupation processes, high levels of contamination, and the absence of clear guidelines, regulations, and urban development executions (Córdoba, 2017;Lopez-Soler, 2021). have the potential to negatively affect mangrove vegetation (Biswas et al, 2018;Chacón-Madrigal et al, 2022). This plant has the ability to rapidly increase its biomass and form dense clumps, spreading by vegetative stolons and extending to completely cover water bodies such as lakes and wetlands (Stohlgren et al, 2013).…”

Mangroves of the Tropical East Pacific (TEP) province is a regional ecosystem subgroup (Level 4 unit of the IUCN Global Ecosystem Typology), present in the coastal ecoregions of the Mexican Tropical Pacific, Chiapas-Nicaragua, Nicoya, Panama Bight, and Guayaquil. In 2020, mangroves cover 7782 km2 in the province, representing 5.3% of the global coverage. In the province, there are eight true mangrove species; however, regional experts recognize other related plants classified as associated plants. The IUCN Red List includes 224 species (217 Animalia and seven Plantae species), supported by records in the Global Biodiversity Information Facility GBIF. It is estimated that the mangroves of the TEP showed a net change of -1.9% from 1996 to 2020; under this trend, a decrease of 3.3% is projected in 50 years, which is below 30%, classifying criterion A2 as least concern. However, based on indicative figures, a decrease of around 40% was estimated in the last 50 years (1970-2020); which as this exceeds 30%, the mangroves are vulnerable under Criterion A1. Although threats such as deforestation, human activities, pollution, infrastructure development, modification of natural systems, and invasion of exotic species are reported, none promote total disappearance; therefore, criteria B3 is classified as least concern. In a sea-level rise scenario (IPCC RCP8.5), ≈ 9.8% of the TEP mangroves would be submerged by 2060, which is below the 30% risk threshold for criterion C2. Furthermore, 1.5% of the province's mangrove is suffering degradation, with the potential to increase to 4.5% over 50-year period; this ranks the mangroves as least concern under criterion D2b. Overall, the Tropical East Pacific mangrove ecosystem was assessed as Vulnerable (VU) with the available information. It is considered that there is insufficient data to assess the other criteria, therefore, it is recommended to update the data to increase the precision of the evaluation and enable the quantitative analysis of risks.
