# Adding a Site  Each experiment is conducted at a unique site. In the context of BETY,  the term 'site' refers to a specific location and it is common for many  sites to be located within the same experimental station. By creating  distinct records for multiple sites, it is possible to differentiate  among independent studies.  1. Before adding a site, search to make sure that site is not already  entered in the database.  2. Search for the site given latitude and longitude  - If an institution name or city and state are given, try to  locate the site on Google Maps  - If a site name is given, try to locate the site using a  combination of Google and Google Maps  - If latitude and longitude are given in the paper, search by lat  and lon, which will return all sites within ± 1 degree lat and  long.  - If an existing site is plausibly the same site as the one  mentioned in the paper, it will be necessary to check other  papers linked to the existing site.  - Use the same site if the previous study uses the *exact same  location* and experimental setup.  - Create a new site if the study was conducted in a different  fields (i.e., not the exact same location).  - Create a new site if one study was conducted in a greenhouse  and another was conducted in a field.  - Do not use distinct sites for seed source in a common garden  experiment (see ’When not to enter a new site’ below)  3. To use an existing site, click `Edit` for the site, and then select  current citation under `Add Citation Relationships`  4. If site does not exist, add a new site.       | Descriptors | Additional Notes |   |:-----------------------------|:-------------------------  | Site Name |Site identifier, sufficient to uniquely identify the site within the paper |  | City | Nearest city |   | State | State, if in the US |  | Country | Country |   | Longitude | Decimal Form. For conversion see the equation in [Table 9](#Table 9) |  | Latitude | Decimal Form. For conversion see the equation in [Table 9](#Table 9) |  | Greenhouse | TRUE if plants were grown in a greenhouse, groth champer of post. FALSE if not used as control |  | Soil |By percent clay, sand, and silt if given |   | SOM |Soil organic matter (% by weight) |   | MAT | Mean Annual Temperature (°C) |  | MAP | Mean Annual Percipitation (mm) |  | MASL |Elevation (meters above sea level, m) |  | Notes | Site Details not included above |  | Soil Notes | Soil details not included above |  | Rooting Zone Depth | Measured in Meters (m) |  |Depth of Water Table| Measured in Meters (m) |  5. Do **not** enter a new site When plants (or seeds) are collected from multiple locations and then grown in the same location, this is called 'common garden experiment'. In this case, the location of the study is included as site information. Information about the seed source can be entered as a distinct cultivar.
