Historically, the importance of botanic gardens was based on their sta
tus as centres for the study and understanding of plants, and on their
usefulness to the developing science of medicine. Recently, however,
these traditional uses of botanic gardens have diminished, and, with m
aintenance costs often exceeding revenues, their continued existence i
s under question. Using data on visitors to four very different botani
c gardens, this study adopts a travel-cost methodology to estimate the
economic benefits which they provide in their role as recreational fa
cilities. These benefits are then aggregated and found to fall far sho
rt of the total grant-in-aid made to each garden, though it is noted t
hat there are other considerations which need to be taken into account
before any firm conclusions can be drawn about the gardens' continued
economic viability.
