Woodland represents little more than 3% of the total area of Lincolnshire, compared with a national average of 10%; however in Lincoln the habitat accounts for roughly 5% of the area of the City. According to the Nature Conservancy Council's 1988 Inventory of Ancient Woodland (defined as having had continuous cover since at least 1600AD and only cleared for underwood or timber production) there are no such areas within Lincoln City.

Outside the Parks, the main woodland areas within the City boundary are around Birchwood and along the Bypass, with Hospital Plantation/Skellingthorpe Moor the largest single area under woodland cover in Lincoln. On many of the City's light sandy acid soils the woods are dominated by birch with occasional oak, rowan and coppiced hazel, sometimes over rhododendron. These woodlands are either plantation ( often of pine or larch, such as The Pheasantry) or secondary, having sprung up following the cessation of grazing and cutting (such as Boultham Moor Wood); in fact they probably account for a greater loss of heathland than development. However this secondary woodland habitat itself is now being lost to housing and industry. The habitat includes riverine willow scrub (developing naturally at many sites including Boultham Park) and willow and alder carr (largely restricted to narrow strips, for example in the Boultham Mere area). Although not strictly woodland Lincoln also possesses perhaps the most northerly pear orchard in Britain (and possibly the largest remaining standard orchard in the county) at Cross O'Cliff Hill.
