Calculate forest fragmentation indices for protected areas in Africa?
Exact submitted task and declared adaptations
Calculate forest fragmentation indices for protected areas in Africa?

Task conventions: This is a closed-catalog task. The complete original GeoBenchX source inventory is listed below; it describes available source types, not actual measurements. Do not supplement it with live data or claim numerical evidence from general knowledge. General knowledge may be used for definitions and explanation. Answer the original question as far as this information environment supports, accurately distinguishing observations, inference and uncertainty. This source-availability/control cohort supplies catalog metadata rather than the observation files and is reported separately from computational tasks.

Recorded final answer

Delivered: a source-availability check. I can’t calculate forest fragmentation indices for protected areas in Africa from this closed catalog. No calculation was run, because the required inputs are not listed here. What is missing: - protected-area boundaries for Africa - an Africa forest-cover or land-cover layer detailed enough to measure forest patches The listed forest sources are only country-level totals and percentages. Those can describe how much forest a country has, but not fragmentation inside protected areas. So they cannot support patch count, mean patch size, edge density, core area, or connectivity. Unanswered requirement: the actual fragmentation indices. Next step: provide Africa protected-area polygons and a matching forest-cover dataset for the same year. ### Limitations - The supplied environment lists source types rather than observation files or measured outputs. - No protected-area boundary source for Africa is listed. - No Africa forest-cover or land-cover source detailed enough for patch analysis is listed. - The supplied catalog does not include Africa protected-area boundaries or an Africa forest-cover layer with patch geometry, so no fragmentation indices can be calculated. - **Protected areas:** Data not found in the supplied catalog. - **Forest pattern:** Those totals cannot show patch size, edges, core area, or connectivity.
