Understanding the 'Stewardship Site' record designation
Any Property, Parcel, or Group record can be designated as a 'Stewardship Site'. Records that have been designated as Stewardship Sites will have the hand-with-a-plant icon in the Portfolio page and when you search for them.
The Stewardship Site designation exists so that stewardship staff can easily filter out those records that are their responsibility. Because records can be nested, (Parcels within Properties or Properties within Groups) it also provides a mechanism so that stewardship staff know which records to enter things like site visits, issues, etc. For various examples of these scenarios, check out this article on Parcels, Properties, and Groups.
Stewardship Site status can be turned on/off by clicking 'Edit Details' from the main record page, then scrolling down to 'Stewardship Details' and update the 'Is Stewardship Site' field.
Importantly, only records that are designated as Stewardship Sites will appear in Landscape Mobile. You can override this within the Mobile App settings.
'How do I know which records to designate as Stewardship Sites?'
For simple single-Property records, anything with a status of 'Current Holding' should probably be a Stewardship Site.
For more complex records such as subdivided easements (single Property/multi-Parcel) or multi-acquisition fee lands (single Group/multi-Property), it may be useful to keep in mind that Landscape uses the 'Stewardship Site' designation to generate the LTA Accreditation Report, wherein each row contains consolidated information on each Stewardship Site. This is because the way land trusts group Stewardship Sites closely mirrors the LTA-accepted counting standards set by Terrafirma. You may want to review these rules as you're thinking about how to organize things.
The one solid rule for designating Stewardship Sites is that they should never overlap. If a Property contains Parcels, only one 'level' should be designated as a Stewardship Site. This helps prevent double-counting when looking at your stewarded acres.
