A recentRestoration Ecologyarticle by Merchant et al. (2022) suggested that practitioners do not regularly use functional traits in restoration planning. We disagree and provide our collective experience that practitioners do leverage traitābased approaches and information, but in ways that are different from researchers. Here, we provide an expanded perspective that incorporates practitioner voices to provide a more complete assessment of how traits are used in restoration practice. We highlight that a major challenge in the field of restoration ecology that leads to a disconnect between researchers and practitioners is a different set of knowledge systems, goals, incentives, and limitations. We provide approaches that researchers can use to connect with practitioners and leverage their knowledge.more » « less

Hovanes, Katherine A.; Lien, Aaron M.; Baldwin, Elizabeth; Li, Yue M.; Franklin, Kim; Gornish, Elise S. (, Invasive Plant Science and Management)Abstract Buffelgrass [Pennisetum ciliare(L.) Link] is an invasive C4perennial bunchgrass that is a threat to biodiversity in aridlands in the Americas and Australia. Topography influencesP. ciliareoccurrence at large spatial scales, but further investigation into the relationship between local-scale topography andP. ciliaregrowth and reproduction would be beneficial. Further, density-dependent effects onP. ciliaregrowth and reproduction have been demonstrated in greenhouse experiments, but the extent to which density dependence influencesP. ciliarein natural populations warrants further investigation. Here we present a study on the relationships between local-scale topography (aspect and slope gradient) and vegetation characteristics (shrub cover,P. ciliarecover, andP. ciliaredensity) and their interactions on individualP. ciliareplant size and reproduction. We measured slope gradient, aspect, shrub cover,P. ciliarecover,P. ciliaredensity, and the total number of live culms and reproductive culms of 10P. ciliareplants in 33 4 by 4 m plots located in 11 transects at the Desert Laboratory at Tumamoc Hill, Tucson, AZ, USA. We modeled the relationships at the local scale of (1)P. ciliarecover and density with aspect and slope gradient and (2)P. ciliaresize and reproduction with abiotic (slope gradient and aspect) and biotic (P. ciliarecover and density and native shrub and cacti cover) characteristics. Aspect and slope gradient were poor predictors ofP. ciliarecover and density in already invaded sites at the scale of our plots. However, aspect had a significant relationship withP. ciliareplant size and reproduction.Pennisetum ciliareplants on south-facing aspects were larger and produced more reproductive culms than plants on other aspects. Further, we found no relationship betweenP. ciliaredensity andP. ciliareplant size and reproduction. Shrub cover was positively correlated withP. ciliarereproduction. South-facing aspects are likely most vulnerable to fast spread and infilling by newP. ciliareintroductions.more » « less
