[1][2][3] This Chase has diverse semi-natural habitats, and its value for invertebrates has been enhanced by military use of the site, which has resulted in a long absence of intensive agriculture.

More recently, military use over a large part has left a series of railway tracks, grassland glades and open pools in the forest.

The integrity of the woodland blocks as a whole is essential to their nature conservation importance,[citation needed] but the relatively unmodified areas are of particular significance.

[4] Yardley Chase contains some large concrete huts, about 12 metres (39 ft) long, and about 6-8m (20–25 feet) wide, which were used during World War II to store bombs.

The eastern munitions site is larger than its western neighbour and the bomb storage buildings, in addition to being less numerous, are also mostly surrounded by water-filled moats.

The official opening event included guests having the opportunity to see and get involved with a variety of Cadet-based activities both inside and outside the new training centre, as well as having a chance to view the new accommodation area.
