The Chiltern Tunnel is a high-speed railway tunnel currently under construction in Buckinghamshire and Hertfordshire, England, and will upon completion carry the High Speed 2 (HS2) railway line under the Chiltern Hills. The twin-bore tunnels, which are 16.04 km (9.97 miles) long, will be the longest on the HS2 line. Each tunnel will also have additional 220 m (720 ft) entry and 135 m (443 ft) exit perforated concrete portals to reduce sudden changes in air pressure and subsequent noise.A contract for the tunnel's construction was awarded in 2017; preparatory work commenced during the following year. In May 2021, it was announced that excavation had commenced. The boring process, which is to be largely performed by a pair of tunnel boring machines (TBMs), is advancing at an average speed of 15 m (49 ft) per day; it is anticipated that it will be complete in March 2024. As of December 2023, the first TBM had excavated a total distance of 15 km (9.3 miles).

Mid Colne Valley is a 132 hectare biological Site of Special Scientific Interest in Harefield in the London Borough of Hillingdon and Denham in South Buckinghamshire. Its main importance lies in its extensive diversity of birdlife in lakes in former gravel pits. The site is divided into three areas. The great majority is in an area of four lakes bounded on the west by the River Colne and on the east by the Grand Union Canal. The river forms the boundary between Greater London to the east and Buckinghamshire to the west, and west of the river in Denham is a small area called Ranston Covert. The SSSI also includes a field called Coppermill Down east of the canal.

Old Park Wood is a 16.7-hectare (41-acre) Site of Special Scientific Interest in Harefield in the London Borough of Hillingdon. The south-east part is an 8-hectare (20-acre) nature reserve owned and managed by the Hertfordshire and Middlesex Wildlife Trust. The site is ancient woodland which dates back to the Domesday Book. It was part of Harefield Park, which had an eighteenth-century house which later became the site of Harefield Hospital.The hilly site is almost wholly wooded, and one of the floristically richest ancient woods in the London area. Its highlight is the abundance of flowers in spring, with a carpet of bluebells together with yellow archangel, lesser celandine, wood anemone and the rare coral root bittercress (cardamina bulbifera).The site is dissected by small valleys and has a variety of types of soil and plants. The trees are mainly oak, birch, hornbeam and ash. Golden saxifrage and marsh marigolds grow along small streams and there is a pond which is important for dragonflies and invertebrates. There is a good variety of birds, including nuthatch and all three British species of woodpecker.The site lies behind Harefield Hospital. There is no access from the hospital, but a footpath along its border fence from Hill End Road leads to the Herts & Middlesex nature reserve. This may be closed as a developer disputes the right of way. Another footpath between Summerhouse Lane and Hill End Road goes through the SSSI, skirting the northern boundary of the nature reserve. The London Loop goes along this footpath.
