Even wondered how tallest trees on Earth, like Coast Redwoods, are measured? One of the most accurate ways is when people like researchers climb them and drop a long tape to the ground. Another method is with laser rangefinders. Actually, when we measured the world’s tallest pine … 268 feet … the climbers tape measurement differed from our laser measurement by only 1 or 2 millimeters ……\u00a0 Select images below for a larger view <\/strong><\/span>… The one photo with Prof. Steve Sillett<\/strong> (HSU) and Chris Atkins<\/strong> was the first day I learned how to measure Coast Redwoods. The same year an opportunity arose to help measure and tag more tallest known Coast Redwoods. The photos give some idea of how steep terrain can be and the effort expended.\u00a0 The man reaching for the prism pole is Giacomo Renzullo<\/strong> … you may have seen him before and not realized it, if you saw the composite images in National Geographic with climbers in a Coast Redwood, and a Giant Sequoia

Laser rangefinders are virtually zero impact to a tree canopy, plus, climbers don’t have time or resources to climb near as many trees.\u00a0 But those are two very accurate ways to do it. I have more about laser rangefinders and measuring in the redwoods here > Laser Rangefinder Page<\/a><\/p>\n

Another page is provided about tallest Coast Redwoods. I’ve listed heights for a lot of trees. There is a circle solver too for calculating trunk diameter or area.\u00a0 Included you should find\u00a0 a link to Michael Taylor’s<\/strong> Landmark Trees website which is frequently updated if you look in his menus for tallest and biggest of several species. He split up the site into both tall and large. See Tallest Coast Redwoods Page<\/a><\/p>\n\n\t\t\t
