Environmental Archaeology On 1st April 2015 the Historic Buildings and Monuments Commission for England changed its common name from English Heritage to Historic England. We are now re-branding all our documents. Although this document refers to English Heritage, it is still the Commission's current advice and guidance and will in due course be re-branded as Historic England. Please see our website for up to date contact information, and further advice. We welcome feedback to help improve this document, which will be periodically revised. Please email comments to [email protected] We are the government's expert advisory service for England's historic environment. We give constructive advice to local authorities, owners and the public. We champion historic places helping people to understand, value and care for them, now and for the future.

It is not intended to be a ‘methods manual’ for all the various types of environmental material, but rather a set of practical guidelines to help with project planning and implementation . Specific guidelines are available for waterlogged wood (Brunning and Watson 2010), waterlogged leather, (English Heritage 1995), human bone (Mays et al 2004; Mays 2005; McKinley and Roberts 1993), geoarchaeology (English Heritage 2007) and dendrochronology (Hillam 1998) .

The Institute for Archaeologists’ (IfA) Standards and Guidance for collection, documentation, conservation and research of archaeological materials (2008e) provides general guidance for all finds work . These guidelines are applicable to all archaeological projects, but are aimed primarily at projects following the management principles set out in MoRPHE and MoRPHE PPN3 (Lee 2006; Kerr and Stabler 2008) . These principles are designed to ensure the efficient execution of archaeological projects within set time and cost constraints, from fieldwork to publication, including the creation of a project archive .
