==== Provisioning services ====
With regards to provisioning services, greater species diversity has the following benefits:
* Greater species diversity of plants increases fodder yield (synthesis of 271 experimental studies).<ref name="the-functional-role-of-producer-diversity">{{cite journal |last1=Cardinale |first1=Bradley J. |last2=Matulich |first2=Kristin L. |last3=Hooper |first3=David U. |last4=Byrnes |first4=Jarrett E. |last5=Duffy |first5=Emmett |last6=Gamfeldt |first6=Lars |last7=Balvanera |first7=Patricia |last8=O'Connor |first8=Mary I. |last9=Gonzalez |first9=Andrew |title=The functional role of producer diversity in ecosystems |journal=American Journal of Botany |date=March 2011 |volume=98 |issue=3 |pages=572–592 |doi=10.3732/ajb.1000364 |pmid=21613148 |bibcode=2011AmJB...98..572C |hdl=2027.42/141994 |hdl-access=free }}</ref>
* Greater species diversity of plants (i.e. diversity within a single species) increases overall [[crop yield]] (synthesis of 575 experimental studies).<ref name="grain-yield-increase-in-cereal-variety-mixtures">{{cite journal|last=Kiaer|first=Lars P.|author2=Skovgaard, M. |author3=Østergård, Hanne|title=Grain yield increase in cereal variety mixtures: A meta-analysis of field trials|journal=Field Crops Research|date=1 December 2009|volume=114|issue=3|pages=361–373|doi=10.1016/j.fcr.2009.09.006|bibcode=2009FCrRe.114..361K }}</ref> Although another review of 100 experimental studies reported mixed evidence.<ref name="does-plant-diversity-benefit-agroecosystems">{{cite journal|last=Letourneau|first=Deborah K. |title=Does plant diversity benefit agroecosystems?
