10 Field Guides for the Serious Naturalist – Cool Green Science

I know some now prefer apps: they’re undoubtedly lighter and even allow you to hear bird songs. (And you can check out birder Tim Boucher’s favorite bird apps in our previous blog). But I still prefer an old-fashioned paper field guide. I love paging through the (often beautiful) illustrations, using the books not only to identify species but to plan future adventures.

About Threatened and Endangered Species Guides: The Threatened and Endangered Species Guides list all the species of the continental United States (i.e., all states except Hawaii) that are classified as endangered or threatened on the U.S.

Endangered Species List. An endangered species or subspecies is one that is in danger of becoming extinct throughout its range or in a portion of its range. All animals and plants on the Endangered Species List are protected by the Endangered Species Act of 1973. About Poisonous and Dangerous Species Guides: PoisonousAn animal is considered poisonous/venomous if it can either inject a poison into a person or produce a poison that is irritating to the touch or if ingested.

Database of Ancient Trees. A new record holder was recently recognized, a Pinus longaeva growing in the White Mountains of eastern California.

Database of Ancient Trees

The date on this tree was reported to me by Tom Harlan. The tree was cored by Edmund Schulman in the late 1950s but he never had a chance to date it before he died. Tom worked up the core only recently, and knows which tree it is. The tree is still alive, and the age given below, 5062, is the tree's age as of the growing season of 2012. Five types of ages are recognized in the database: XD: crossdated RC: ring counted EX: extrapolations (usually based on ring measurements) HI: historic record C14: radiocarbon dated wood samples from a tree (added 2007) Crossdated ages are derived through recognized dendrochronological procedures (e.g., Stokes and Smiley 1968; Swetnam, Thompson, and Sutherland 1985; Schweingruber 1987).
