Living Landscape Plan vis drafts

Landscape-level analysis of Kew outdoor areas only. Glasshouses, nurseries, and non-landscape features are excluded. All taxonomic diversity measures use WCVP-accepted names resolved at query level.

Taxonomic Diversity

Figure 1: Fig. 2 Shannon diversity index (genus-level, accepted names) across Kew landscape areas. Higher values indicate more even genus representation.

NoteData: Fig. 2

Figure 2: Fig. 3 Relationship between collection size (log scale) and genus-level Shannon diversity. Marker size proportional to genus count; colour encodes family count.

Conservation Value

Figure 3: Fig. 4 Percentage of alive objects with IUCN threat status (CR, EN, or VU) per landscape area.

NoteData: Fig. 4

Figure 4: Fig. 5 Conservation density: distinct IUCN-threatened taxa per hectare. Identifies areas where conservation value is most spatially concentrated.

NoteData: Fig. 5

Figure 5: Fig. 6 IUCN threat category breakdown for landscape areas containing at least one threatened object. EW, Extinct in the Wild; CR, Critically Endangered; EN, Endangered; VU, Vulnerable.

Wild-Source Provenance

Figure 6: Fig. 7 Percentage of objects with wild-source provenance (W, Z, or N) among those with known provenance data. Denominator is objects with known provenance, not total objects, to avoid penalising areas with older records.

NoteData: Fig. 7

Figure 7: Fig. 8 Provenance data completeness: percentage of alive objects with any provenance code recorded. Low values indicate areas dominated by older accessions.

Wild-Source × Threatened Overlap

Figure 8: Fig. 9 Count of distinct taxa per area that are both wild-collected and IUCN-threatened (CR, EN, or VU). These represent irreplaceable wild genetic resources of conservation concern.

Native GB Biodiversity

Figure 9: Fig. 10 Percentage of alive objects representing taxa native to Great Britain (WCVP, TDWG Level 3 region GRB).

Inspection Health

Figure 11: Fig. 12 Percentage of alive objects with overdue stock-check status per landscape area.

Collection Age & Renewal

Figure 12: Fig. 13 Median accession year of alive objects per landscape area. Green indicates younger collections; red indicates older established plantings.

NoteData: Fig. 13

Figure 13: Fig. 14 Percentage of alive objects accessioned in the last 10 years (≥2016). Indicates areas of active planting and renewal.

NoteData: Fig. 14

Figure 14: Fig. 15 Collection age profile vs renewal rate. Marker size proportional to object count; colour encodes percentage of threatened objects.
