“…The mechanical disking facilitated this evenness by tilling, chopping, and spreading existing vegetative propagules throughout the soils. The utilization of stored nutrient reserves in root/bud tissue and tillers allow for fast re-establishment in species such as tall fescue and Chinese lespedeza (Hartnett and Keeler, 1995;Willand et al, 2013). Tilling also increases the bare ground and light penetration, which may stimulate the germination from the seed bank (Kalamees and Zobel, 2002;Yurkonis and Meiners, 2006); however, our study did not assess seed bank viability.…”

“…Because opportunities for establishment of desired individuals and species decline over time within the grassland reconstruction process (Willand et al 2013), it is important to use reconstruction techniques that maximize establishment from the desired seed mixture within the first few growing seasons. Neighborhood (cm-scale) interactions during this establishment phase strongly affect subsequent species co-existence (Milbau et al 2007, Korner et al 2008, and several options exist to manipulate the number (density) and identity of individuals in a seedling's immediate neighborhood within the reconstruction process.…”

Aggregating Species at Seeding May Increase Initial Diversity during Grassland Reconstruction

Because the distances over which plants interact can be relatively short, the extent to which individuals interact with conspecific and heterospecific neighbors during the initial phases of grassland reconstruction may affect local species diversity and invasibility. To determine whether aggregating conspecific individuals at seeding (while controlling seed density) can be used as a technique to improve tallgrass prairie establishment, we used a greenhouse experiment with four native tallgrass prairie species (functional diversity controlled) seeded at three evenness levels into potting soil. We randomly assigned species to one (random) or a group of four (aggregated) fixed locations in an 8 × 8 grid (16 cm × 16 cm with 2 cm spacing) and subsequently seeded half of the communities with the non-native cool-season grass intermediate wheatgrass (Thinopyrum intermedium). After the equivalent of one growing season (four months), aggregated communities were more diverse and had a marginally greater proportion of legumes than random communities. Initial species pattern did not affect community invasibility, but invaded communities were less diverse and more dominated by the native cool-season grasses. Our results suggest that some tallgrass prairie species may benefit from initial conspecific aggregation and confirm that interactions that determine diversity, but not necessarily invasibility, during grassland establishment occur over short (cm-scale) distances. Aggregating seeds of conspecific species within the grassland reconstruction process may be used as a technique to improve diversity in grassland reconstruction sites and future projects need to consider whether these initial responses can be replicated and maintained within field-scale projects.

“…We hypothesized that the number of emerged ramets would not be influenced by dominant grass population source because this functional group comprises the majority of ramets in remnant (Benson & Harnett ; Dalgleish & Hartnett ) and restored (Willand et al. ) prairie. Further, there is little evidence supporting variation in above‐ground net primary productivity (ANPP) between population sources (Wilsey ; Baer et al.…”

Question: Does population source of dominant species influence propagule abundance and richness for ecological restoration, and are effects consistent across different species pools? Location: Illinois, USA.Methods: Abundance and richness of ramets, emerged seedlings, seed rain and the soil seed bank were measured in a restoration experiment consisting of a split-plot design with population source of dominant grasses (cultivar vs local ecotype) as the whole-plot factor and sown subordinate species (three unique pools of non-dominant species) as the subplot factor, respectively. Different sown species pools were included to assess whether any observed differences in propagule abundance or richness between the dominant species sources was generalizable across varying interspecific interactions.Results: Abundance of emerged ramets was similar between communities sown with cultivar and local ecotypes of the dominant grasses, but differed among sown species pools in prairie restored with cultivars but not with local ecotypes. Number of emerged seedlings also differed among species pools, but only in communities sown with local ecotypes of the dominant grasses. There was also higher seedling emergence in communities sown with local ecotypes relative to cultivars of the dominant grasses in one species pool. Richness of the seed rain was influenced by an interaction between dominant grass population source and sown species pool, resulting from (1) higher richness in prairie restored with local ecotypes than cultivars of the native grasses in one species pool, and (2) differences in richness among species pools that occurred only in prairie restored with the local ecotype grass source. Abundance and richness of the seed bank was not affected by dominant grass population source.Conclusions: This study addressed a poorly understood potential effect of using cultivars in ecological restoration, specifically on the abundance and supply of propagules for community assembly. We found no consistent negative effect of dominant grass cultivars on propagule supply. These results suggest that if both local ecotype and cultivar sources are available for restoration, using local ecotypes could result in more seedling germination and richness in the seed rain.
