Volunteers from the Watford and Three Rivers Trust (W3RT) have donated and helped install 40 bird boxes at Longspring Wood Nature Reserve in Kings Langley.
The high-quality boxes were built by members of W3RT Five Ways Friends clubs for the over-55s.
Some of the bird boxes have already been installed at Longspring Wood under the supervision of Laura Baker, reserves officer at Herts and Middlesex Wildlife Trust.
The rest will be installed in time for next season.
The boxes will support local birds such as warblers, robins and finches.
Laura said: “We are delighted with the Watford and Three Rivers Trust volunteers’ donation. Longspring Wood comes alive over the spring and summer and these bird boxes will encourage even more wildlife by creating more habitat capacity.
“Our priority over the next year is to clear holly and scrub to open up more areas in the wood, encouraging a greater diversity of native woodland plants. The reserve is in an urban area, which means that the local community will really see a difference in the wildlife on their doorstep.”
Longspring is a good example of Hertfordshire woodland with oak, ash and hazel trees.
Warblers can be seen and heard in spring. In winter, flocks of tits and finches move through the wood feeding on seeds and berries, and badgers and foxes are regularly seen.
