Resumo
The alarming rate of global pollinator decline has made habitat restoration for pollinators a
conservation priority. At the same time, empirical and theoretical studies on plant-pollinator networks
have demonstrated that plant species are not equally important for pollinator community persistence
and restoration. However, the scarcity of comprehensive datasets on plant-pollinator networks in
tropical ecosystems constrains their practical value for pollinator restoration. As closely-related
species often share traits that determine ecological interactions, phylogenetic relationships could
inform restoration programs in data-scarce regions. Here, we use quantitative bee-plant networks
from Brazilian ecosystems to test if priority plant species for different restoration criteria (bee species
richness and visitation rates) can be identified using interaction networks; if phylogenetic relationships
alone can guide plant species selection; and how restoration criteria influence restored network
properties and function. We found plant species that maximised the benefits of habitat restoration for
bees (i.e., generalists and those with distinct flower-visitor species) were clustered in a small number
of phylogenetically-diverse plant families, and that prioritising the recovery of bee visitation rates
improved both stability and function of restored plant-pollinator networks. Our approach can help
guide restoration of pollinator communities, even where information on local ecosystems is limited.
