Some nuthatches, such as the Eurasian nuthatch and the North American species, have extensive ranges and large populations, and few conservation problems,<ref name="Birdlife">{{cite web| title= ''Sitta'' | work= Species Search Results | url= http://www.birdlife.org/datazone/species/index.html?action=SpcHTMFindResults.asp&hdnAction=SEARCH&hdnPageMode=0&cboFamily=-2&txtGenus=sitta&txtSpecies=&txtCommonName=&cboRegion=-2&cboCountry=-2| publisher= [[BirdLife International]] | access-date=2008-06-21}}</ref> although locally they may be affected by woodland fragmentation.<ref name="Varo"/><ref name="vanLangeveld">{{cite journal| last= van Langevelde | first= Frank | year=2000 | title= Scale of habitat connectivity and colonization in fragmented nuthatch populations | journal= Ecography | volume=23 | issue= 5 | pages= 614–622 | jstor = 3683295 | doi = 10.1111/j.1600-0587.2000.tb00180.x| doi-access= free | bibcode= 2000Ecogr..23..614V }}</ref> In contrast, some of the more restricted species face severe pressures.

The [[Endangered species|endangered]] white-browed nuthatch is found only in the [[Nat Ma Taung|Mount Victoria]] area of Burma, where forest up to {{convert|2,000|m|ft|abbr=on}} above sea level has been almost totally cleared and habitat between {{convert|2,000|–|2,500|m|ft|abbr=on}} is heavily degraded. Nearly 12,000 people live in the Natma Taung [[national park]] which includes Mount Victoria, and their fires and traps add to the pressure on the nuthatch. The population of the white-browed nuthatch, estimated at only a few thousand, is decreasing, and no conservation measures are in place.<ref>{{cite iucn |author=BirdLife International |date=2016 |title=''Sitta victoriae'' |volume=2016 |page=e.T22711167A94281752 |doi=10.2305/IUCN.UK.2016-3.RLTS.T22711167A94281752.en |access-date=11 November 2021}}</ref><ref name="ThetZawNaing">{{cite journal| author = Thet Zaw Naing | year= 2003| title= Ecology of the White-browed Nuthatch ''Sitta victoriae'' in Natmataung National Park, Myanmar, with notes on other significant species | journal= Forktail | volume= 19 | pages= 57–62 | url =http://birdingasia.org/wp-content/uploads/2012/09/Naing-Nuhatch.pdf }}</ref> The Algerian nuthatch is found in only four areas of Algeria, and it is possible that the total population does not exceed 1,000 birds.

Deforestation has also caused population declines for the [[Vulnerable species|vulnerable]] Yunnan and yellow-billed nuthatches. The Yunnan nuthatch can cope with some tree loss, since it prefers open pine woodland, but although still locally common, it has disappeared from several of the areas in which it was recorded in the early 20th century.<ref>{{cite iucn |author=BirdLife International |date=2017 |title=''Sitta yunnanensis'' |volume=2017 |page=e.T22711192A116898695 |doi=10.2305/IUCN.UK.2017-3.RLTS.T22711192A116898695.en |access-date=11 November 2021}}</ref> The threat to yellow-billed is particularly acute on Hainan, where more than 70% of the woodland has been lost in the past 50 years due to shifting cultivation and the use of wood for fuel during Chinese government re-settlement programmes.<ref>{{cite iucn |author=BirdLife International |date=2018 |title=''Sitta solangiae'' |volume=2018 |page=e.T22711219A132095305 |doi=10.2305/IUCN.UK.2018-2.RLTS.T22711219A132095305.en |access-date=11 November 2021}}</ref>

Krüper's nuthatch is threatened by urbanisation and development in and around mature coniferous forests, particularly in the [[Mediterranean]] coastal areas where the species was once numerous. A law promoting tourism came into force in Turkey in 2003, further exacerbating the threats to their habitat. The law reduced bureaucracy and made it easier for developers to build tourism facilities and summer houses in the coastal zone where woodland loss is a growing problem for the nuthatch.<ref name="Sittakrueperi">{{cite iucn |author=BirdLife International |date=2016 |title=''Sitta krueperi'' |volume=2016 |page=e.T22711184A94282660 |doi=10.2305/IUCN.UK.2016-3.RLTS.T22711184A94282660.en |access-date=11 November 2021}}</ref><ref name=Turkey>{{cite web | title=Turkey: briefing notes on tourism policy and institutional framework | url=http://www.transanatolie.com/turkce/turkiye/turkiye%20gercekleri/turkey%20handbook-tourism.pdf | publisher=The Travel Foundation | access-date=22 July 2008 |url-status = dead| archive-url=https://web.archive.org/web/20090225143556/http://www.transanatolie.com/turkce/turkiye/turkiye%20gercekleri/turkey%20handbook-tourism.pdf | archive-date=25 February 2009 }}</ref>
