Seed mix design and application to overcome seed limitation in floodplain forest restorations
… of reference sites for use in restoration seed mixes. This methodological approach highlighted significant differences in various ecological traits between species of reference and restored sites and revealed the inadequacy of commercial seed mixes in representing these indicator species. …

Enhancement of diversity via disturbance and seed addition in two sand prairies dominated by different grasses
… addition, community structure may be limited by seed availability, or a combination of microsite and seed limitation. Studies of these factors aid our basic ecological understanding of the maintenance of diversity in grasslands, but also are pertinent to restoration and management of grasslands. …

The demography of Balanites maughamii : an elephant-dispersed tree
… populations from the infrequent recruitment of seedlings, and facilitates the maintenance of populations over the short term. Balanites maughamii trees are reliant on African elephants (Loxodonta africana) for seed dispersal and to provide a germination cue through mastication. In the absence of …

The influence of rainfall variability on savanna tree seedling establishment
… the rainfall requirements necessary for tree seedling survival of different savanna species in the first year of growth. Results from a field drought experiment showed that dry season survival for seedlings of Acacia nigrescens and Philenaptera vialacea was not related to wet season length. …

Processes determining plant species diversity in restored tallgrass prairie
… of soil characteristics, management actions, seed mix design, and site characteristics for predicting prairie restoration success. We found that across many restorations, invasion by exotic plants was the best predictor of outcomes, significantly reducing beta-, and site-level plant diversity. …

Livestock impact assessment and restoration strategies in the semi-arid Karoo
… is a consequence of poor water infiltration and seed limitation was tested in a restoration experiment. It appeared that natural seed availability is not limiting, but water infiltration has to be improved to initiate the restoration process. Removal of shrub material in long-ungrazed and moribund …
