“…Perhaps unsurprisingly, we tend to think about, care for, and manage rare species much more than common ones, even though the functional value of rare species (and other rare things) is rarely in line with their scientific importance in an ecosystem ( Metrick and Weitzman, 1996 , Koford and Tschoegl, 1998 , Gerber, 2016 ; but see Bracken and Low, 2012 and Jain et al., 2014 for counter-examples). Even among rare species, most resources directed at implementing recovery plans for their populations or protecting necessary “habitat” (which may include a foundation species) for their continued persistence are showered on only a handful of taxa ( Metrick and Weitzman, 1996 , Gerber, 2016 ).…”
