GRIN Taxonomy for Plants

"The National Plant Germplasm System of the Agricultural Research Service, U.S. Department of Agriculture maintains a computer database, the Germplasm Resources Information Network (GRIN), for the management of and as a source of information on its 568,489 germplasm accessions. The taxonomic portion of GRIN provides the classification and nomenclature for these genetic resources and many other economic plants on a worldwide basis.

AlgaeBase Taxonomy

"You can browse though the hierarchy by clicking on the names below and drilling down. At each level the numbers of current species are given for each taxon. Only currently accepted names are currently included. Should you find any errors, please click on the little envelope icon, and you can send me an e-mail via the site. In order to make calculations of the numbers of species of living algae, note that 68 or so species of flowering plants (seagrasses) are included for the present (under the Phylum Magnoliophyta), and about 2000 fossil algae, mainly calcium- and silica- secreting forms.

New Zealand Threat Classification System

"The New Zealand Threat Classification System's long-term goal is to list all extant species that exist here according to their threat of extinction. The system is made up of manuals and corresponding taxa status lists. The status of each species group (birds, plants, reptiles, etc.) is assessed over a 3-year cycle."

Classification of Environmental Protection Activities and Expenditure

"CEPA is a functional classification used to classifiy activities, products, outlays and other transactions whose primary purpose is environmental protection. It is a hierarchic classification with 3 levels (level 1: 9 categories, level 2: 46 categories, level 3: 20 categories)."

Kasvien suomenkieliset nimet

"Kasvien suomenkieliset nimet ­-ontologia tarjoaa kattavan kokoelman suomenkielisiä nimiä ja niiden tieteellisiä vastineita. Ontologia sisältää lajinimistöä eri puolilta maailmaa sekä kattavan määrän puutarha- ja viljelykasvinimistöä. Biologisen nimistön ajallinen muuttuvuus on huomioitu Kassun tietomallissa siten, että nimien muutosketjut ovat jäljitettävissä. Hauissa tulee näkyviin viimeisin voimassaoleva nimi. Kassu on ladattavissa sekä SKOS- että OWL-kielisen version sisältävänä tiedostona.

Wildland Planning Glossary

"More than 1400 terms useful in wildland and related resource planning are defined. The purpose of the work is to facilitate communication between professionals, not to provide them with exhaustive vocabularies of each other's specialties. Definitions are drawn from many sources, including public laws and government manuals, but are not intended to establish legally binding definitions. A list of terms and list of sources are included."

Classification of the Biogeographical Provinces of the World

"This is a hierarchical system which consists of (1) biogeographic regions, i.e. major taxa; (2) biotic provinces withinthe regions. Further, each province is characterized by a (3) major biome or biome-complex. As discussed above, we re-name the first two items (biogeographical realm, biogeographical province)."
