Abstract Natural revegetation, afforestation, and lignocellulosic crops for bioenergy, possibly coupled with a developing technology like carbon capture storage, are the most common land-based climate change mitigation options. However, they can compete land threaten food security or nature conservation. Using abandoned cropland their deployment minimize these risks, but associated potentials u...

Ecosystem integrity on steep mountain slopes and in high elevation landscapes is in general a question of soil stability, which in turn depends on plant cover and rooting patterns. Terrestrial net primary production and decomposition rates in arctic and alpine ecosystems are low and revegetation after human disturbance can take centuries. Relatively few species regulate the annual input and los...

Vegetation change in arid areas may lead to the redistribution of regional water resources, which can intensify competition between ecosystems and humans for resources. This study aimed accurately model impact vegetation on hydrological processes an endorheic river watershed undergoing revegetation, namely, middle lower reaches Bayin River basin, China. A LU-SWAT-MODFLOW was developed by integr...

Ecologists and land managers around the world are charged with first arresting and then reversing declines in native species. Revegetation has been proposed as one of the mechanisms by which landscapes can be rehabilitated to support viable populations of native wildlife. Because large-scale revegetation often proves to be technically difficult and costly, it is critical to evaluate the likely ...

Spectral signatures represent complex physical and biophysical relationships. Consideration and documentation of potential variables affecting these signatures are essential in obtaining meaningful spectra. A lack of standardised procedures and metadata collection has limited the transfer of spectra from one application to another. Here we describe the design and implementation of a standard me...

Abstract—Genetic diversity in plant materials used for revegetation of disturbed sites is important to allow natural selection and adaptation to occur. Several methods for estimation of genetic diversity using molecular markers are available. Protein markers, such as isozymes and seed storage proteins, have been used extensively, but their use has declined in recent years in favor of DNA marker...
