De onde o Plotwright reúne o conhecimento sobre plantas

Canadian plant hardiness maps and related climate suitability tools, including recent 1991-2020 mapping and USDA-equivalent extreme minimum temperature maps.

The Brazilian national flora authority — the official, continuously-updated checklist of the plants, algae, and fungi of Brazil maintained by the Rio de Janeiro Botanical Garden under the Reflora programme. Plotwright’s region-appropriate native-status + taxonomy reference for Brazilian flora.

A biodiversity data network for occurrence records and species evidence, useful for distribution context and source trails.

A community observation platform useful for observation context, phenology leads, and selected licensed plant photos.

A native-plant-focused reference covering ~9,000 North American native species, with structured per-state native distribution and Xerces Society pollinator value flags integrated into each plant page.

A strong horticultural reference for garden plant profiles, photos, and care context, with specific image-use conditions.

A continental conservation-status reference for plants, animals, and ecosystems, publishing per-subnation native flags and conservation ranks (G/N/S) for US states and Canadian provinces via a single-call public JSON API.

A curated extension plant reference with horticultural traits, right-plant/right-place guidance, and Creative Commons image metadata.

Curated narrative profiles for the world’s ecoregions — geography, characteristic vegetation, climate, flagship species, and conservation status — built on the Dinerstein et al. framework. Plotwright’s primary source for ecoregion editorial summaries.

Kew’s global taxonomic authority for vascular plants: the accepted name, full synonymy, and the native / introduced distribution (TDWG botanical-country resolution) for ~1.4 million names. Plotwright’s region-appropriate primary botanical authority for European and global flora — and a reliable native-range source for species (hybrids, tropical, neotropical) that a US extension toolbox does not profile.

Unverified plant notes created inside Plotwright before a fact has been backed by a public record, extension source, or expert review.

The peer-reviewed 2017 map of the world’s 846 terrestrial ecoregions — successor to the WWF 2001 scheme — with each ecoregion’s biome, biogeographic realm, area, and "Nature Needs Half" protection tier. The structural foundation of every Plotwright ecoregion page.

The Royal Horticultural Society’s horticultural plant reference for UK + European gardeners — cultivation guidance, RHS hardiness ratings (H1a–H7), Award of Garden Merit status, and right-plant/right-place notes. Plotwright’s region-appropriate horticultural reference for European garden plants.

A stock-photo source for free-to-use images that can support early public pages when each photo URL and credit is retained.

The U.S. hardiness-zone reference for average annual extreme minimum temperature, with map graphics, GIS data, and ZIP-code lookup.

A public plant record system for U.S. and territory plant identity, distribution, status, wetland, invasive, noxious, and conservation data.

A media repository with public-domain and freely licensed images, useful when per-file attribution and license metadata are preserved.

Community-maintained encyclopedia articles used as a corroborating cross-check for ecoregion descriptions — geography, vegetation, and climate — alongside the primary RESOLVE and curated One Earth sources.
