Spatial units description
Spatial units for Dimorphandra wilsonii were delineated based on a combination of population structure, geographic barriers, threat-defined Locations, and conservation action. Watersheds, mountain ranges, and other geological features were treated as as proxies for subpopulations. In addition to this, spatial groupings of individuals, the size of groupings, genetic structure (where data was available), distance, and connectivity potential were taken into account. Where there was high connectivity within a group, but threats and conservation actions varied substantially between different parts of the group, the group was split into two or more spatial units to capture this variation. Factors considered in these divisions included proximity to urban areas, habitat quality, ongoing or potential reintroduction, area protection, the availability of fire brigades, and local communities' involvement in the species’ participatory conservation plan. Information about the bases for delineating each spatial unit can be found in the 'Description' column of the 'Spatial Units in detail' section below.
The names of spatial units correspond to the municipalities in which the species is present today, though it is possible that these populations extended beyond the named municipalities in the past. For units in which the species is currently Absent, the names refer to all municipalities within the modelled past extent of occurrence. These are areas where the species has not been found yet but may exist, or may have existed in the past.

Ecological Function
Functionality description
It is very challenging to define a Functional population of this species. Functional redundancy prevents the use of ecological indicators of functionality, and proxies for functionality (e.g. pre-impact density or carrying capacity) are unavailable because there is no information about the species prior to human impacts. All remnant habitat patches have been impacted by human activities.
The patch with the highest current density contains two individuals per hectare; however, even this area is subject to agriculture pressure. A Functional population would need to exhibit at least this density. Another critical indicator of functionality is the representation of different growth stages: adults, juveniles, and evidence of recruitment. If these criteria are met in most of the indigenous habitat area, and there are no threats that may be limiting population densities to below pre-impact levels, a spatial unit can be considered Functional.
