A growing number of industrial disturbances are reclaimed with native grass species, although use of many native forbs in reclamation is limited due to low availability, high expense, poor germination, and lack of information on how to successfully establish them. Therefore, a study was conducted to assess the performance (establishment, growth, and survival) of native forbs (10 species by seeding and 12 species by transplanting) on disturbed sites planted in different seasons (spring and fall) and subjected to different types of vegetation management (mowed and unmowed). All seeded forb species established successfully, although density of most of the native forbs was very low (<20 stems/plot). Transplanted forb species established well, with 65% of seedlings surviving two growing seasons. Establishment and survival of seeded and transplanted native forbs were associated with plant competition, where forbs established well with annual weeds and less successfully with perennial weeds. Both spring seeding and transplanting increased forb establishment; and seeding and transplanting in fall versus spring produced more seed. Mowing generally had limited effects on forbs. Of the seeded species, Vicia americana, Achillea millefolium, and Ratibida columnifera consistently had the highest densities across treatments, whereas spring transplanting increased establishment of Anemone cylindrica, Gaillardia aristata, Geum triflorum, Monarda fistulosa, and Dalea purpurea. Spring‐transplanted forbs spread over a larger area than fall‐transplanted forbs. In most cases, seeding and transplanting native forbs in the spring can be more effective than in fall to reclaim disturbed sites if land management practices are used to control perennial weeds.

“…Habitat availability may play an important role in determining whether species are not only rare but also of conservation concern, particularly for species with strong affinities to habitats that have been subject to large‐scale disturbance or conversion by humans (e.g. plains rough fescue; Elsinger et al 2023). Historical contingencies also affect species' occurrence: for example, past glaciation events have left a lasting imprint on species' range limits (Svenning and Skov 2004).…”

The three‐dimensional rarity typology proposed by Rabinowitz in 1981, based on geographic range, habitat specificity, and local abundance, is among the most widely used frameworks for describing rarity in ecological and conservation research. While this framework is descriptive and is not meant to explain the causes of rarity, recent advances in ecology may be leveraged to add explanatory power. Here we present a macroecological exploration of rarity and its underlying causes. We propose a modification of Rabinowitz's typology to better distinguish between the dimensions of rarity and the ecological processes that drive them, and explore the conservation implications of our modified framework. We propose to add occupancy (the proportion of occupied sites within a species' range) as a rarity axis, and recast habitat specificity as a cause of rarity, thus yielding a modified classification based on range size, occupancy, and local abundance. Under our framework, habitat specialists are no longer considered rare if they are widespread and abundant; we argue that this modification more accurately identifies truly rare species, as habitat specialists may be common if their habitat is abundant. Finally, we draw on the macroecological and theoretical literature to identify the key processes and associated traits that drive each rarity axis. In this respect, we identify four processes (environmental filtering, movement, demography and interactions), and hypothesise that range size and occupancy are primarily driven by environmental filtering and movement, whereas local abundance is more strongly influenced by demography and interactions. We further use ecological theory to hypothesise the conservation concerns associated with each rarity axis, and propose conservation measures that may be suitable for conserving different types of rare species. Our work may provide a basis for developing hypotheses about the causes of rarity of particular focal taxa or groups, and inform the development of targeted conservation strategies.

“…El crecimiento global de la industria de petróleo y gas natural ha requerido la creación de vastas redes de tuberías subterráneas. En la actualidad, existen 7 millones de kilómetros de tuberías en todo el mundo y cada año se siguen instalando nuevos ductos para conectar la matriz energética en la mayoría de los países (Elsinger et al 2023;Brehm & Culman, 2022). Sin embargo, la instalación de una tubería conlleva inevitablemente a perturbaciones ecológicas potenciales (Olson & Doherty, 2012;Xiao et al 2014), ya que el proceso de construcción implica el desbroce de la cubierta vegetal, la excavación y la compactación del suelo (Tekeste et al 2020).…”

La instalación de tuberías subterráneas es una infraestructura necesaria para la conexión de la matriz energética en la mayoría de los países. Sin embargo, se desconoce en detalle cuáles son los cambios de la composición a largo plazo y la estructura temporal de la cubierta vegetal, así como los efectos sobre la biodiversidad en ecosistemas áridos en la estepa magallánica. Para mitigar esto, se propone evaluar la recuperación de la cubierta vegetal un pastizal nativo (coironal) que forma parte de estos ecosistemas. El objetivo del estudio es identificar los efectos producidos por la instalación de un ducto de hidrocarburos con el método de elevación doble y posterior de revegetación con siembra de una mezcla de semillas agronómicas, sobre la composición, estructura y diversidad en comparación con un pastizal no perturbado adyacente (sitios de referencia) durante un periodo de 7 años. Se estudió el área del Bloque Coirón, en las cumbres de San Gregorio, región de Magallanes, Chile. Se identificaron 28 taxones en el área modificada por el ducto y 39 en la vegetación de referencia. La biodiversidad fue mayor en la vegetación de referencia en comparación al ducto, donde se observó una disminución del número de especies y porcentaje de cobertura. El análisis de Componentes Principales (PCA) y el análisis SIMPER permitieron identificar cuales especies contribuyeron más significativamente a la similitud dentro de cada grupo. Los resultados mostraron que se necesitan al menos 7 años para recuperar las áreas intervenidas por la instalación de un ducto de hidrocarburos y que la presión del pastoreo y eventos climáticos como el déficit hídrico, pueden estar interfiriendo en la recuperación de la cubierta vegetal
