“…Very likely, under these conditions the plant may behave as an annual, and when the adult plant dies, there are new seedlings. This characteristic of adaptation to fire has been observed in other invasive species in North America (22,68,69) . In other studies, it has been reported that fire increases the probability of natal grass invasion (5) .…”

RESUMEN El pasto rosado (Melinis repens) es una especie introducida de África que invade diversos ecosistemas. EnMéxico se encuentra en todos los Estados, y en Chihuahua es la especie dominante en extensas áreas de pastizales. Las invasiones reducen la calidad y cantidad de los productos y servicios del ecosistema. No se sabe exactamente cuándo llegó al continente americano. Dependiendo de las condiciones climáticas puede comportarse como anual o perenne de vida corta. Produce abundante semilla durante años con precipitaciones por debajo de lo normal comparados con años lluviosos. La germinación de la semilla puede ser en presencia de luz o sin ella, la máxima germinación es entre 20 a 35 ºC; a -0.2 MPa se inhibe la germinación y el fuego no la afecta. ABSTRACTNatal grass (Melinis repens) is an introduced specie from Africa that is invading different ecosystems. In Mexico, it is present all over the country and dominates large areas of grasslands. Plant invasion reduces quality and quantity of ecosystem goods and services. The knowledge of the biology of invasive species is a key factor when a management and control plan will be established. It is unknown when this specie arrived to America. Depending on climatic conditions this grass may behave as annual or perennial. Seed production is larger in years with precipitation below normal than in wet years. Germination takes place with or without light, optimum temperature is from 20 to 35 ºC; at -0.2 MPa germination is inhibited, and fire does not affect seed germination. When moisture is not limited and during the early development, root:shoot ratios ranges from 1.13 to 1.90 and relative growth rate from 0.0034 to 0.15 mg g-1 d-1 ; also, biomass is reduced when natal grass grows on native soil compared to sterilized soil. Although it is considered as poor forage, the main use is as pasture. Other uses reported include ornamental, medicinal, and fito-remediation. Fire favors its growth, and no control method is known. So far, grazing of natal grass is the most viable management. Additionally, when planning a control campaign it is important to reduce the movement of this specie as part of human activities.

“…However, in dense stands of B. tectorum, elimination of this annual grass may be necessary to achieve success in perennial revegetation (Klomp and Hull, 1972). Fire can be used to eliminate the dense cover of B. tectorum and prepare the ground for seeding (Hull and Stewart, 1948;Robocker et al, 1965), although recurrent fires may favor this annual grass by reducing the competition with perennials (Mata-Gonza´lez et al, 2007;Pickford, 1932;Whisenant, 1990).…”

This study measured water‐use efficiency of wildland vegetation at the whole‐plant level during two contrasting years to better understand ecosystem responses to precipitation fluctuations in the Great Basin, USA. Biome‐representative species included grasses (Distichlis spicata, Leymus triticoides, and Sporobolus airoides), desert shrubs (Artemisia tridentata, Atriplex confertifolia, and Ericameria nauseosa), wetland/riparian plants (Glycyrrhiza lepidota, Juncus arcticus, and Salix exigua), and an exotic annual (Salsola tragus). Plants were grown in 5·8 m2 plots in a common garden in eastern California. Four watering treatments were applied monthly during two summers: control (no water other than natural precipitation), low (1·3 cm), medium (2·6 cm), and high (3·9 cm). Water‐use efficiency, here termed water to production (WTPa), was the ratio of water transpired to aboveground biomass produced. Biomass production was 50% lower and WTPa was five times higher during 2009 than 2010. WTPa decreased with watering during 2009 but increased with watering during 2010. Year differences determined vegetation productivity and response to summer watering and were related to the lower winter/spring precipitation during 2009 than 2010. Desert shrubs were more drought tolerant than grasses and wetland plants. Yet, an increase in summer precipitation would primarily benefit herbaceous species and not desert shrubs. Desert shrubs achieved greater standing crop but lower root‐to‐shoot ratio (RSR) than herbaceous species. Nonetheless, the grass S. airoides had the greatest standing crop overall, mainly because of its greater root production (RSR 5·5). Species differences in growth, WTPa, and biomass allocation should be considered in land management and conservation practices. Copyright © 2012 John Wiley & Sons, Ltd.
