Gymnosperm Database: Links
Essential Links
These are links that provide significant additional information on many of the species addressed in the Gymnosperm Database. Because they are so comprehensive, it is not practical for me to add them to each page of each species concerned.
The Biodiversity Heritage Library is probably the world's greatest repository of old botanical literature. The original publications of most conifer species can be found here.
Botanic Gardens Conservation International (BGCI) provides a variety of very useful tools, including (1) a global tree database that will tell you the distribution of any tree, or a list of all the trees in a country; (2) a climate change tool that tells you whether a tree will survive at a given site under a given climate change scenario; and (3) overview conservation assessments for all trees.
The China Natural Herbarium is an invaluable resource for any species native to China. It provides descriptive information, range maps, an extensive library of photos, and much further information. What's more, it's all closed to search engines such as Google, so you will not otherwise see this information.
Conifers of the World provides an online portal to the complete BRAHMS database used by Aljos Farjon to assemble his World Checklist and Bibliography of Conifers and the Handbook of the World's Conifers. Contains over 30,000 database records.
GBIF, the Global Biodiversity Information Facility, is a database with species distribution information. iNaturalist records, among others, are kept here. This is a useful resource for developing species distribution maps, but it has to be used carefully; a significant fraction of specimens seem to be misidentified or or to be horticultural specimens not identified as such.
The Glossary of Botanical Terms on Wikipedia is reasonably complete. Also, most specialized terms, such as distichous or mucronate, can be found at The Free Dictionary.
Google Scholar is the first place I look to find a PDF of a recent academic publication. Researchgate is the second.
Google Translate provides automated translations. You can enter text or a URL. This site will be useful for anyone pursuing links on non-English pages, and may also be helpful to non-English speakers using the Gymnosperm Database.
iNaturalist is usually the first place I look for good-quality photos of conifers. These can be extremely useful in attempting to identify a species you haven't seen before.
Index Herbariorum is an index to over 3,100 herbaria around the world, providing contact information and herbarium codes.
Individual Tree Species Parameter Maps is useful for trees native to the 48 US states, allowing mapping of specific parameters in their distribution, such as basal area or tree density. Note that these maps tend to underestimate distribution outside of federal lands.
Inside Wood is an essential resource for identifying a species by its wood. Includes both fossil and extant taxa (not just gymnosperms) with detailed information on anatomy and a large library of high-resolution photographs of woods in section.
The Multilingual Multiscript Plant Name Database gives plant names in many different languages, using the correct script (e.g. Cyrillic, Kanji) as well as a Roman transliteration.
The Native American Ethnobotany Database describes foods, drugs, dyes and fibers of native American peoples, derived from plants.
Threatened Conifers of the World, sponsored by the Royal Botanic Garden Edinburgh, provides conservation information, case studies, and new items regarding the world's 211 threatened or endangered conifer species.
World Agroforestry is a great resource for finding information on species, particularly tropical and subtropical species, used in agroforestry.
Databases
Africa Cycads provides good photos, distribution maps and descriptions for nearly all African cycads, i.e. Encephalartos and Stangeria.
The Atlas of Relations Between Climatic Parameters and Distributions of Important Trees and Shrubs in North America is an online version of USGS Professional Paper 1650-G, providing range and climatic requirements of most species of North American conifers. See also Little's Atlas, which has both distribution maps and downloadable ArcView shapefiles.
The Australia Virtual Herbarium (AVH) is an excellent database holding records from most Australian herbaria.
The Bibliography of Dendrochronology is a searchable database that includes virtually everything ever published up to 2012 on the subject of dendrochronology. Unfortunately the bibliography is no longer maintained and searches of the more recent literature can be quite challenging.
The Conifer Treasury is a comprehensive listing of conifer cultivar names and many incidentals of conifer culture assembled by Zsolt Mesterházy.
Dendrobox is a map-based engine to find and display tree-ring data archived by the International Tree-Ring Data Bank. Searchable by species, location, and investigator. This is one of the tools I use to find very old trees.
The Russian Conifer Society addresses systematics, distribution, cultivation, ornamental use, and lore for all conifers native to Russia, and many other species besides. Moreover, the society's perspective is often highly distinctive in comparison to typical European and American discussions.
