  "description": "Cloud-native mirror of the Barred Owl Tool (https://barredowltool.russell.wisc.edu), a decision-support tool that prioritizes where to concentrate invasive barred owl (Strix varia) population control to protect the northern spotted owl (Strix occidentalis caurina). Coproduced by the University of Wisconsin-Madison Peery Wildlife Ecology + Conservation Lab and the US Fish & Wildlife Service with support from NASA's Ecological Conservation program; prioritization uses the prioritizr systematic-conservation-planning R package, solving a 'maximum utility' objective (maximize weighted coverage of the input layers under a fixed management-area budget) to optimality with an exact solver. All inputs are summarized onto a fixed ~5 km2 hexagonal grid (37,048 cells range-wide, keyed by HEXID) covering the range of the northern spotted owl (western Washington, western Oregon, northwestern California). This collection normalizes the tool's outputs into two artifacts: (1) an 'inputs' layer holding the 7 input variables that are INVARIANT across every scenario (stored once, as GeoParquet + PMTiles + H3 res-8 hex); and (2) a long 'scores' table holding the prioritizr priority score (prio_score, 0-1 where 0 = not prioritized) for each of the 2,754 scenarios (51 management units x 3 threat modes x 6 tuning parameters x 3 weight levels), joinable to the inputs on HEXID. Each scenario covers the hexes within its management unit (range-wide runs cover all ~37k hexes; province and GMA runs cover fewer). The priority score is the only per-hex value that changes across scenarios, and it is renormalized within each management unit.",
