Field notes
The species inventory combines common and scientific names, family labels, and conservation markers; the page reports 29% native to Java and 48% native to Indonesia (WCVP). Its vegetation assessment estimates 12.2% canopy cover (95% interval: 9.3–15.1%) from 500 random points interpreted on Google imagery using i-Tree Canopy. A separate census is measuring, mapping, and numbering trees at least 10 cm DBH; individual records are explicitly deferred until verification.
