Linwood is part of a major woodland conservation area, centred on Linwood Warren 1.5 miles (2.4 km) to the north-east,[3] and is a primary target area to promote and encourage the repopulation of the Woodlark (Lullula arborea), a native bird that has become almost extinct locally. In 2005 the population had been raised to approximately 50 breeding pairs and 60 other male birds, after more than 15 years of work monitored by the Lincolnshire Bird Club.
