The objectives of the Warwickshire Geodiversity Action Plan are to: 1 identify and audit the geodiversity resource 2 conserve, manage and monitor Warwickshire’s geodiversity 3 embed the geodiversity concept, its significance and the need to conserve local geodiversity, throughout the planning system. 4 conduct research on Warwickshire’s Warwickshire Museum Warwickshire geodiversity © Quarries enable investigation of the area’s geodiversity 5 increase awareness of and support which would otherwise be hidden underground. One for Warwickshire’s geodiversity such location is Cross Hands Quarry (a Site of Special with reference to professional Scientific Interest) which allows amateur and museum- bodies, conservation practitioners, led groups to collect fossils and learn about sedimentary landowners, the education sector, rocks in a safe, accessible environment. The quarry and the general public exposes limestones of Middle Jurassic age. The rock beds have yielded significant research findings including 6 initiate, support and conduct a new species of dinosaur and the fossilised remains educational initiatives concerning of a diverse Jurassic sea-life. local geodiversity Alan Cook Alan 7 integrate geoconservation with © bioconservation and landscape quality initiatives 8 measure our progress The value of quarries to the study of geodiversity can be extended if owners manage the features of interest, especially where working has ceased. Grants from the Aggregate Levy Sustainability Fund (ALSF) have en- abled recommendations to be made for geoconservation at sites such as Griff Hollows (Local Geological Site 74) through the development of Site Management Plans. These identify the main features of the sites, record them accurately, suggest possible management strategies and set the sites in their environmental, biodiversity and historical contexts.
