'''Firs''' are [[evergreen]] [[conifer]]ous trees belonging to the [[genus]] '''''Abies''''' ({{IPA|la|ˈabieːs|lang}}) in the family [[Pinaceae]]. There are approximately 48–65<ref>{{Cite journal |last1=Torres |first1=Leon Nahuel |last2=Shi |first2=Xiao |last3=Na |first3=Yuling |last4=Wang |first4=Bing |last5=Tian |first5=Chi |last6=Chen |first6=Jun |date=2024-03-01 |title=First study on fossil wood from the Middle Pleistocene of the Songliao Plain, Northeast China |url=https://www.sciencedirect.com/science/article/pii/S0034666724000149 |journal=Review of Palaeobotany and Palynology |volume=322 |pages=105063 |doi=10.1016/j.revpalbo.2024.105063 |bibcode=2024RPaPa.32205063T |issn=0034-6667}}</ref><ref>Debreczy  Zsolt  Rácz István  and Kathy Musial. 2011.

They are large trees, reaching heights of {{convert|10|–|80|m|ft|abbr=off}} tall with trunk diameters of {{convert|0.5|–|4|m|ftin|abbr=on}} when mature. Firs can be distinguished from other members of the pine family by the way in which their needle-like [[leaves]] are attached singly to the branches with a base resembling a [[suction cup]], and by their [[Conifer cone|cones]], which, like those of [[Cedrus|cedars]], stand upright on the branches like candles and disintegrate at maturity.

Identification of the different species is based on the size and arrangement of the leaves, the size and shape of the cones, and whether the [[bract]] scales of the cones are long and exserted, or short and hidden inside the cone.

=== Leaves ===<!-- Fir needle redirects here. -->

</gallery>

Firs can be distinguished from other members of the pine family by the unique attachment of their needle-like [[leaves]] to the twig by a base that resembles a small [[suction cup]]. The leaves are significantly flattened, sometimes even looking like they are pressed, as in ''[[Abies sibirica|A.&nbsp;sibirica]]''.

The leaves have two whitish lines on the bottom, each of which is formed by [[wax]]-covered [[stoma]]tal bands. In most species, the upper surface of the leaves is uniformly green and shiny, without [[stoma]]ta or with a few on the tip, visible as whitish spots. Other species have the upper surface of leaves dull, greyish green or bluish to silvery ([[glaucous]]), coated by wax with variable number of [[stoma]]tal bands, and not always continuous. An example species with shiny green leaves is ''[[Abies alba|A.&nbsp;alba]]'', and an example species with matt waxy leaves is ''[[Abies concolor|A.&nbsp;concolor]]''.

The tips of leaves are usually more or less notched (as in ''[[Abies firma|A.&nbsp;firma]]''), but sometimes rounded or dull (as in ''[[Abies concolor|A.&nbsp;concolor]]'', ''[[Abies magnifica|A.&nbsp;magnifica]]'') or sharp and prickly (as in ''[[Abies bracteata|A.&nbsp;bracteata]]'', ''[[Abies cephalonica|A.&nbsp;cephalonica]]'', ''[[Abies holophylla|A.&nbsp;holophylla]]''). The leaves of young plants are usually sharper.

The leaves are arranged spirally on the shoots, but by being twisted at their base, the way they spread from the shoot is diverse; in some species comb-like ('pectinate'), with the leaves flat on either side of the shoot (e.g. ''[[Abies alba|A.&nbsp;alba]]'', ''[[Abies grandis|A.&nbsp;grandis]]''), in others, the leaves remain radial (e.g. ''[[Abies pinsapo|A.&nbsp;pinsapo]]'')<ref name="Seneta81" />

Foliage in the upper crown on cone-bearing branches is different, with the leaves shorter, curved, and sometimes sharp.<ref name="Arno-2020">{{Cite book |last1=Arno |first1=Stephen F. |url=https://books.google.com/books?id=qDD4DwAAQBAJ |title=Northwest Trees: Identifying & Understanding the Region's Native Trees |last2=Hammerly |first2=Ramona P. |publisher=[[Mountaineers Books]] |year=2020 |isbn=978-1-68051-329-5 |edition=field guide |location=Seattle |pages=125 |language=en |oclc=1141235469 |orig-date=1977 |access-date=2022-02-26 |archive-date=2023-09-19 |archive-url=https://web.archive.org/web/20230919000929/https://books.google.com/books?id=qDD4DwAAQBAJ |url-status=live }}</ref>

</gallery>

Firs differ from other conifers in having erect, cylindrical [[Conifer cone|cones]] {{convert|5|-|25|cm|in|0|abbr=on}} long that disintegrate at maturity to release the winged [[seed]]s. In contrast to [[spruce]]s, fir cones are erect; they do not hang, unless heavy enough to twist the branch with their weight.

The mature cones are usually brown. When young in summer, they can be green:
:''[[Abies grandis|A. grandis]]'', ''[[Abies holophylla|A. holophylla]]''

or reddish:
:''[[Abies alba|A.&nbsp;alba]]'', ''[[Abies cephalonica|A.&nbsp;cephalonica]]'', ''[[Abies nordmanniana|A.&nbsp;nordmanniana]]''

or bloomed pale glaucous or pinkish:
:''[[Abies numidica|A.&nbsp;numidica]]'', ''[[Abies pinsapo|A.&nbsp;pinsapo]]''

or purple to blue, sometimes very dark blue, almost black:
:''[[Abies forrestii|A.&nbsp;forrestii]]'', ''[[Abies fraseri|A.&nbsp;fraseri]]'', ''[[Abies homolepis|A.&nbsp;homolepis]]'', ''[[Abies lasiocarpa|A.&nbsp;lasiocarpa]]'', ''[[Abies pindrow|A.&nbsp;pindrow]]''.

Many species are [[polymorphism (biology)|polymorphic]] in cone colour, with different individuals of the same species producing either green or purple cones:
:''[[Abies concolor|A.&nbsp;concolor]]'', ''[[Abies koreana|A.&nbsp;koreana]]'' (usually purple, rarely green, such as the [[cultivar]] 'Flava'), ''[[Abies magnifica|A.&nbsp;magnifica]]'' (usually green, occasionally purple), ''[[Abies nephrolepis|A.&nbsp;nephrolepis]]'' (f.&nbsp;''chlorocarpa'' green), ''[[Abies sibirica|A.&nbsp;sibirica]]'', ''[[Abies veitchii|A.&nbsp;veitchii]]'' (f.&nbsp;''olivacea'' green)<ref name="Seneta81" />

The cone scale bracts can be short and hidden in the mature cone, or long and exposed ('exserted'); this can vary even within a species, e.g. in ''[[Abies magnifica]]'' var. ''magnifica'', the bracts are hidden, but in var. ''critchfieldii'' and var. ''shastensis'', they are exserted. The bracts scales are often a different colour to the cone scales, which can make for a very attractive combination valued in ornamental trees.

== Ecology ==
Firs are used as food plants by the [[caterpillar]]s of some [[Lepidoptera]] species, including ''[[Chionodes]] abella'' (recorded on [[white fir]]), [[autumnal moth]], [[Korscheltellus|conifer swift]] (a pest of [[balsam fir]]), [[engrailed (moth)|the engrailed]], [[grey pug]], [[mottled umber]], [[pine beauty]] and the [[tortrix moth]]s ''[[Cydia illutana]]'' (whose caterpillars are recorded to feed on [[European silver fir]] cone scales) and ''[[Cydia duplicana|C.&nbsp;duplicana]]'' (on European silver fir bark around injuries or [[canker]]).

''[[Abies religiosa]]'' (sacred fir) trees give [[Monarch butterfly roosts|roosting]] shelter to overwintering [[Danaus plexippus|monarch butterflies]].<ref>{{cite web | last =Groth | first =Jacob | title =Monarch Migration Study | publisher =Swallowtail Farms | date =10 November 2000 | url =http://www.swallowtailfarms.com/pages/educationalproducts_mms.html | access-date =21 July 2014 | archive-date =9 May 2022 | archive-url =https://web.archive.org/web/20220509093135/http://www.swallowtailfarms.com/pages/educationalproducts_mms.html | url-status =live }}</ref><ref>{{cite web | url =http://www.monarchjointventure.org/monarch-biology/monarch-migration/ | publisher =Monarch Joint Venture | title =Monarch Migration | year =2013 | access-date =2017-10-25 | archive-date =2017-10-31 | archive-url =https://web.archive.org/web/20171031023829/https://monarchjointventure.org/monarch-biology/monarch-migration/ | url-status =live }}</ref>

== Phytochemistry ==
''Abies'' produce a variety of [[terpenoid]]s. The analyses of the Zavarin group{{Snd}}from Smedman et al. 1969 to Zavarin  et al. 1977{{Snd}}showed variation in terpenoid composition of the bark by genetics, geography, age and size of the tree.<ref name="Hemingway-2018">{{cite book |last=Hemingway |first=R.

== Uses ==
[[File:Laukaa.vaakuna.svg|thumb|upright=0.7|Green fir twig pictured on top of heart in the coat of arms of [[Laukaa]]]]

[[Wood]] of most firs is considered unsuitable for general [[timber]] use and is often used as [[Pulp (paper)|pulp]] or for the manufacture of [[plywood]] and rough timber. It is commonly used in [[Canadian Lumber Standard]] graded wood.<ref name="Homebuilding">{{cite web | last=Jenkins | first=Steve | title=What is CLS timber and what DIY projects is it good for? | website=Homebuilding & Renovating | date=2023-09-03 | url=https://www.homebuilding.co.uk/advice/what-is-cls-timber | access-date=2024-08-22}}</ref> Because this genus has no insect or decay resistance qualities after logging, it is generally recommended in construction purposes for indoor use only (e.g. indoor [[drywall]] on [[Timber framing|framing]]). Firwood left outside cannot be expected to last more than 12 to 18 months, depending on the type of climate it is exposed to.{{cn|date=April 2025}}

[[Abies nordmanniana|Caucasian fir]], [[Abies procera|noble fir]], [[Abies fraseri|Fraser's fir]] and [[Abies balsamea|balsam fir]] are popular [[Christmas tree]]s, generally considered to be the best for this purpose, with aromatic foliage that does not shed many needles on drying out. Many are also decorative garden trees, notably [[Abies koreana|Korean fir]] and Fraser's fir, which produce brightly coloured cones even when very young, still only {{convert|1|–|2|m|ftin|abbr=on}} tall. Many fir species are grown in botanic gardens and other specialist tree collections in Europe and North America.<ref>{{cite web |url=https://treesandshrubsonline.org/articles/abies/ |title=Christian, T.
