Las islas flotantes son un tipo de humedal artificial en donde se instalan macrófitos emergentes sobre estructuras flotantes y son utilizadas en fitodepuración, paisajismo y proyectos de conservación. Con el objetivo de aumentar las especies de la colección viva, embellecer los cuerpos de agua y contribuir a los procesos de conservación, en el Jardín Botánico de Bogotá (Colombia) se evaluó el establecimiento de 12 especies de plantas acuáticas presentes en Cundinamarca sobre un nuevo diseño de estructura flotante. Se construyeron tres estructuras flotantes octagonales con materiales reciclables y de bajo costo, con un área de 1.51 m2 en donde se plantaron 141 individuos de: Cuphea racemosa (L.f.) Spreng., Eleocharis dombeyana Kunth, Equisetum bogotense Kunth, Hydrocotyle leucocephala Cham. & Schltdl., Hydrocotyle mexicana Cham. & Schltdl., Hydrocotyle sp., Juncus microcephalus Kunth, Ludwigia peruviana (L.) H.Hara, Osmunda regalis L., Plantago australis Lam., Polytrichadelphus longisetus (Brid.) Mitt. y Sagittaria latifolia Willd. Para evaluar el establecimiento de las plantas se tomaron fotografías desde el plano cenital y se usó una clasificación supervisada de tipo likelihood para cuantificar la cobertura vegetal a las 6, 23 y 44 semanas. También se evaluó el porcentaje de supervivencia y la presencia de brotes. Luego de 44 semanas se encontró una respuesta diferencial en las especies, siendo O. regalis y L. peruviana las que presentaron los mejores resultados.

Wetland restoration is an important way to improve ecosystem services, but many wetland nurseries lack the facilities that are traditionally used to produce large numbers of native plants used in these projects. Our goal was to evaluate growth and performance of four wetland species in a variety of substrates, fertilizer regimes, and irrigation methods under greenhouse conditions. Plants were grown in pots with drainage holes filled with one of four substrates (potting substrate, topsoil, sand, 50/50 mix of topsoil, and sand) amended with 0, 1, 2, or 4 g of 15N–3.9P–10K controlled-release fertilizer per liter of substrate. Irrigation was supplied via an overhead system or subirrigation. After 16 weeks of production, plants were scored for visual quality and plant height before a destructive harvest. Broadleaf sagittaria (Sagittaria latifolia) was mostly unaffected by substrate type but performed best when subirrigated and fertilized with 4 g·L−1 of fertilizer. Growth of skyflower (Hydrolea corymbosa) and cardinal flower (Lobelia cardinalis) was best when fertilized with 2 or 4 g·L−1 of fertilizer and grown using overhead irrigation. String lily (Crinum americanum) was unaffected by substrate type but produced the largest plants when subirrigated. These experiments provide guidance for cultivating these wetland species under greenhouse conditions, which may allow growers to efficiently produce plant material needed for the restoration market.

Where many different plant species occupy an environmental gradient, the responses of their offspring to that gradient could show one of two patterns. All species could have similar requirements for maximum recruitment, in which case all would show maximum germination and emergence in the same region of the gradient ("shared responses"). Alternatively, each species could have different requirements for recruitment and therefore would show maximum recruitment in different regions of the gradient ("distinct responses"). The objective of this study was to test between these two alternatives in plants occurring along a water level gradient. Seeds of 11 wetland species were allowed to germinate in sand along a gradient of water depth, ranging from 10 cm above to 5 cm below the substrate surface. Scirpus americanus, S. validus, Sagittaria latifolia, Typha angustifolia, and Lythrum salicaria showed no significant response to this gradient, while Spartina pectinata, Polygonum punctatum, Bidens cernua, Acorus calamus, Alisma plantago-aquatica, and Eupatorium perfoliatum did. However, the six species in the latter group did not exhibit shared preferences along the water depth gradient. These different recruitment patterns were consistent with adult distributions in the field. Most species showed some recruitment at all water levels examined, suggesting that they have broad tolerance limits for water level in the recruitment phase of their life history.
