The ICUN lists the lanner falcon as "least concern", citing overall numbers world-wide as well as evidence it may be increasing in numbers<ref>http://www.arkive.org/lanner-falcon/falco-biarmicus/</ref>. Evidence for the increase may have involved human activity; areas cleared of trees provided hunting grounds for the birds. However, the desire for lanner falcons in the sport of falconry has caused a decline in other areas. South Africa reported a decline in numbers, while Europe has listed the bird as endangered, estimating 850-1,700 individual birds<ref>http://www.iucnredlist.org/details/22696487/0</ref>. The after-effects of the use of pesticides has also been cited as a factor.
