“…The low abundance of forbs (Warkins and Howell 1983;Howe 1994aHowe , 1994bHowe , 1999Brown and Bugg 2001) and dominance of P. virgatum (Schramm 1990;Corbett et al 1996;Baer et al 2002) was not unique to our experiment. Many studies have noted the difficulty in establishing subdominant forb species in grassland restorations (Warkins and Howell 1983;Zajicek et al 1986;Howe 1999;Jackson 1999).…”

Plant community responses to resource availability and heterogeneity during restoration

Availability and heterogeneity of resources have a strong influence on plant community structure in undisturbed systems, as well as those recovering from disturbance. Less is known about the role of resource availability and heterogeneity in restored communities, although restoration provides a valuable opportunity to test our understanding of factors that influence plant community assembly. We altered soil nitrogen (N) availability and soil depth during a prairie restoration to determine if the availability and/or heterogeneity of soil resources influenced plant community composition in restored grassland communities. Plant community responses to three levels of N availability (ambient, enriched by fertilization, and reduced by carbon amendment) and two levels of soil depth (deep and shallow) were evaluated. In addition, we evaluated plant community responses to four whole plot heterogeneity treatments created from the six possible combinations of soil N availability and soil depth. The soil depth treatment had little influence on community structure during the first 3 years of restoration. Total diversity and richness declined over time under annual N enrichment, whereas diversity was maintained and richness increased over time in soil with reduced N availability. Non-native species establishment was lowest in reduced-N soil in the initial year, but their presence was negligible in all of the soil N treatments by the second year of restoration. Panicum virgatum, a native perennial C(4) grass, was the dominant species in all soil N treatments by year three, but the magnitude of its dominance was lowest in the reduced-N soil and highest in enriched-N soil. Consequently, the relative cover of P. virgatum was strongly correlated with community dominance and inversely related to diversity. The differential growth response of P. virgatum to soil N availability led to a higher degree of community similarity to native prairie in the reduced-N treatment than in the enriched-N treatment. There were no differences in plant community structure among the four whole plot-level heterogeneity treatments, which all exhibited the same degree of similarity to native prairie. Diversity and community heterogeneity in the whole-plot treatments appeared to be regulated by the dominant species' effect on light availability, rather than soil N heterogeneity per se. Our results indicate that a strong differential response of a dominant species to resource availability in a restored community can regulate community structure, diversity, and similarity to the native (or target) community, but the importance of resource heterogeneity in restoring diversity may be dampened in systems where a dominant species can successfully establish across a range of resource availability.

“…The soils also contain high concentration of Al, Mn, Fe, Zn, and Cu which are toxic to the plants. Moreover, shortage of soil micro-flora restricts the decay of plant material due to which the natural biodiversity is invaded by inferior species (Corbett et al 1996;Singh et al 2002). Some mineral overburdens release salt, heavy metal, and radioactive pollutants, effluents like ammonia, arsenic, asbestos, cadmium, copper, cyanide, lead, mercury, etc., which on leaching contaminates the land and water resources.…”

Wasteland is defined in various ways by different agencies. However, in general it represents degraded, unused, and uncultivated lands. These lands have utilized in recent past to bridge the gap between demand and supply of food, fodder, timber, and also for resource conservation. Area under mines in the country is about 0.19 m ha and ravine lands 4 m ha. Though mining is important for industrial growth, it also has negative impact on the environment and renders the land unproductive. Rehabilitation of such degraded areas requires systematic and scientific approach which includes proper survey, choice of species, and techniques for establishment of plant species. Rehabilitation of ravine lands involves treatment of table and marginal lands contributing runoff to the gullies and proper gullies/ravines on watershed basis. It requires an integrated approach of using gullies according to land capability classes, soil, and water conservation measures and putting land under permanent vegetation cover involving, afforestation, agroforestry, horticulture, pasture, and energy plantations. Watershed development has become the major intervention for managing natural resources. Majority of the watersheds in the country are degraded and suffer from poor productivity, biotic pressure, acute fodder shortage, poor livestock productivity, poverty, water scarcity, and poor infrastructure. A multitier ridge to valley sequenced approach is required to treat the watersheds for enhancing productivity and resource conservation. This

“…De modo geral, as áreas degradadas por deposição de rejeitos industriais, contaminadas com metais pesados, tendem a apresentar alta heterogeneidade (Corbett et al, 1996). Além disso, a associação de mais de uma espécie de metal tóxico dificulta interpretações acuradas sobre a ecologia dos FMAs nestas áreas.…”

“…Entretanto, para o estabelecimento de uma comunidade de plantas estáveis nestas condições, a comunidade microbiana deve ser diversa e funcional, incluindo, por exemplo, os fungos que formam as micorrizas arbusculares (MAs). Estes ocorrem nas raízes da maioria das plantas, mesmo em condições adversas (Brundrett, 1991;Cuenca et al, 1998), e em solos com excesso de metais pesados Weissenhorn et al, 1995a,b;Corbett et al, 1996), tornando-se os microrganismos predominantes na rizosfera e com grande influência sobre as plantas.…”

RESUMOOs fungos micorrízicos arbusculares (FMAs) ocorrem de forma generalizada e formam importante simbiose com a maioria das plantas, mesmo em solos poluídos com metais pesados. Neste estudo, avaliaram-se a ocorrência e a diversidade dos FMAs em quatro locais com gramíneas em uma área de solo contaminado com metais pesados pela extração e industrialização do Zn. Verificou-se a ocorrência generalizada dos FMAs nos locais estudados, sendo esta influenciada pelas concentrações de metais no solo. Encontrou-se um total de 21 espécies, sendo: sete pertencentes ao gênero Acaulospora, seis de Scutellospora, cinco de Glomus, duas de Gigaspora e uma de Entrophospora. Glomus occultum, Acaulospora morrowiae, Acaulospora mellea, Glomus intraradices, Glomus clarum e Scutellospora pellucida foram as de maior ocorrência. A densidade de esporos, a riqueza de espécies e o aumento da dominância relacionaram-se inversamente com as concentrações de metais no solo. Acaulospora mellea, Glomus clarum e Glomus occultum dominaram as populações de esporos no solo. Concluiu-se que os metais pesados exerceram efeito diferenciado sobre os FMAs, dependendo do grau de poluição.
