The reserve lies fully within the boundaries of the City of Lincoln but is still a comparatively quiet and secluded sanctuary for wildlife. It was originally a site excavated for ballast during the construction of the railway. The area has since become an attractive lake with beds of both reeds and sedge. There are mature trees and shrubs which now go alongside the railway.

The reserve attracts many birds, particularly wading and waterfowl, such as teal, shoveler, and goldeneyes, the type of duck that lent their name to the James Bond film. Other birds around the nature reserve include reed and sedge warblers, great crested grebes and even little grebes. Kingfisher and common tern also have nests at Boultham Mere.

There is an abundance of dragonflies and damselflies at the nature reserve, with 12 species regularly recorded. There is also an absolute plethora of butterfly species found in summer such as orange tip, ringlet, large skipper, meadow brown and wall brown.

Although the postcode listed for the nature reserve is LN6 7BH, visitors should be aware that this is for the nearest registered address, so are for reference only. Luckily due to its size, Boultham Mere can be easily signposted by all Lincoln residents.

Home to a diverse and elaborate wildlife population, Boultham Mere nature reserve is actually less than a mile from Lincoln city centre, and can be accessed from the Tritton Road area. There are several car parks which can be used for walkers and bird watchers, with a small track between Morrisons and Farm Foods signposting the way. The track is generally good, but can be somewhat ropey after patches of bad weather. There is also no shelter until you reach Boultham Mere itself, and even then this is limited to a birdwatching hide, so visitors are reminded to dress accordingly.

Across summer, the area is covered by wildflowers. However, the warmer weather and lake also attract mosquitoes, so visits on windless days are a bit of a trial. Snow and ice help transform Boultha, Mere into a magical wonderland, but do make the walk from the road feel a lot longer and riskier!

Formerly known as the Skewbridge Ballast Pit, the reserve is bounded by the railway and Pyewipe Main Drain, but is a comparatively quiet and secluded sanctuary. Covering over 47 acres, the reserve attracts many wintering wildfowl.

The reserve provides one of only two regular sites in Lincolnshire for wintering bittern. Recent years have provided examples of even rarer birds such as Savi’s warbler, marsh warbler, purple heron, goshawk, Mediterranean gull, and even osprey.

The area is popular among nature fans, dog walkers, and families alike, although Boultham Mere Nature Reserve is really only good for better weather due to its relatively inaccessible pathways.
