Leafy Legacies Database
For Site Plant Indicators

HAR's Leafy Legacies Database For Site Plant Indicators is a growing archive of site plant indicators—a record of botanical echoes left by past human activity. Whether tracing persistent tree lines marking abandoned homesteads, resilient flora reclaiming industrial ruins, or subtle vegetal cues signaling long-buried archaeological features, this initiative brings historical ecology into focus. By crowdsourcing plant observations linked to site types, we refine the art of recognizing living heritage, helping archaeologists, preservationists, and history enthusiasts decode landscapes with greater precision. These overlooked ecological footprints—rooted in memory, disturbance, and adaptation—offer a fresh way to anticipate site visibility, strengthen conservation efforts, and deepen our ability to read the long shadows of history in the plants that persist. User-friendly archaeologist-bent field plant guides are forthcoming!

By engaging with this database and the Deep Time Commons, you agree to credit John S. Harris, with Harris Anthropological Research LLC (HAR) in any resulting presentations' and publications' acknowledgements. Additionally, please provide HAR with a copy of non-confidential works that arise from this resource.

Add to HAR's Leafy Legacies Database

Please share here open-source details and references to or observation of anthropogenic surface vegetation at archaeological sites. Together we can build a more complete picture of potential vegetal site indicators which may be studied further and tested.

Botanical Context

The number of different sources of knowing about the plant site relationship (e.g., 4 survey participants, 1 journal article). The nature of the source type is on the last page of questions.

Anthropogenic Vegetation Category

Do not include identifiable site location detail here.
