Logging may decrease some populations but the overall effect it has on Cooper's hawks is generally considered unknown. As with all Accipiters, Cooper's hawks can presumably only withstand a certain level of loss of habitat before an area becomes essentially unlivable. Studies in Arizona determined that heavily grazed agricultural areas were favored over lightly grazed ones due to greater prey concentrations in the latter habitats. On the contrary, in the early 1990s (while the species was generally recovering), the species was considered to be state-endangered in New Jersey, with ongoing harmful effects found for poorly-regulated (or entirely unregulated) logging and land development within of active nests. In the Black Hills, harvesting of ponderosa pines appears to be causing the Cooper's and both other species of Accipiter to vacate large parts of the forest. It has been recommended that a buffer zone of at least , with a median estimated space needed of about , should be free from human disturbance or development to retain the protected nests of Cooper's hawks. Studies in New Mexico showed that these hawks are reliant on the conservation of riparian woodlands in much of the southern part of the state. Despite the large, productive and genetically diverse population of Cooper's hawks in Tucson, several authors have hypothesized, controversially, that the city is an ecological trap, due to the unsustainably high turnover for nestlings via Trichomoniasis-related mortality and for adults via frequent lethal collisions. Other studies support that the number of fatal window and wire collisions of urban-living Cooper's hawks is excessively high. Quite few Cooper's hawks have ever been gathered for use in falconry. This hawk is fairly unpopular in falconry practices due to its high-strung personality and is additionally considered in such captive conditions as given towards tyrannical, hysterical and demanding behaviors, even compared to its similarly disposed larger cousin, the northern goshawk, which is fairly popular in falconry.
