aijc = core area (m2) of patch ij based on specified edge depths (m). |
| Description | TCA equals the sum of the core areas of each patch (m2), divided by 10,000 (to convert to hectares). |
| Units | Hectares |
| Range | TCA ≥ 0, without limit. TCA = 0 when every location within every patch is within the specified depth-of-edge distance(s) from the patch perimeters. TCA approaches total landscape area as the specified depth-of-edge distance(s) decreases and as patch shapes are simplified. |
| Comments | Total core area is defined the same as Core area (CORE) at the patch level (see Core Area), but here core area is aggregated (summed) over all patches. |
