Tallest Northern California Eucalyptus

Post by yofoghorn » Mon Jun 09, 2014 1:31 pm

A week ago, Luke Hickman, my friend, and I discovered a grove of Eucalyptus globulus in Contra Costa County that are significantly tall! They are competing with redwoods and are actually taller than the redwoods they are competing with. There are 4 trees taller than 240', the two tallest being 243', one with a substantial lean. The tallest hardwood in the northern and western hemispheres that I'm aware of is a 246' Eucalyptus on Santa Cruz Island. In a few years, these Eucalyptus will likely become records for the hemispheres, as they are in a perfect area to continue growing taller. These are now the Eucalyptus and hardwood (non native) height records for Northern California.

Welcome back Zane, you've no doubt been busy in the woods!
When you say Santa Cruz Island, is that one of the Channel Islands?

I always wondered how a redwood/eucalyptus grudge match would play out. Though, the redwoods do better further north don't they?

Eucalyptus/Redwood matches result in taller Eucalyptus usually. I've seen two groves of Eucalyptus over 230' that have been competing with redwoods. The redwoods are around the same height. When it comes to tree competition, whatever the least amount required to reach the sun is good enough for the competitor.

Eucalyptus over 200' are are rare in California.
Great find Hawkeye !

I don't know about northern hemisphere, better check some of the Eucalyptus trees that have been growing for centuries in Spain and other European countries with a Mediterranean climate. I read about them but have forgotten the information. Last I heard, there were some extremely big Eucalyptus trees there.

OK I did a quick google search and found a 75 meter eucalypt in Portugal

http://www.git-forestry.com/KarriKnight ... icolor.htm

That's around 245 feet.

Supposedly the tallest tree in Europe.

This tallest known Eucalyptus of Europe in Portugal was lasermeasured as 72 m (236 ft) in November 2010 by Dean Nicolle, a Eucalyptus specialist from Australia.
See http://www.monumentaltrees.com/en/prt/c ... anas/8314/ . So the height of 75 m (245 ft) reported in 2003 probably was not accurately measured.

This is still the tallest known tree in Europe, as Kouta has stated.

Jeroen,

Thanks, It is important to correct such information. Botanical taxonomist Scott Mori says in Tropical Plant Collecting From the Field to the Internet "In this age of electronic communication, the propagation of errors is increasingly common, because the review process is often less rigorous than it is for hard copy publication". ... "when information based on incorrect determinations is added to electronic species pages, the species pages may include elements from two or more species and, thus, become "mixed" pages. Species pages created using Wiki technology need to be viewed with special caution, because anyone can modify them with additional text or images, increasing the probability that pages will end up including information for more than one species". I think this is somewhat analogous, or in some way relates to putting tree measurements on the internet without listing a precise measurement technique. I recall years ago when there was a wiki type site where the general public would answer questions like "what is the biggest centipede" or "biggest tree" and invariably the most popular answers were flat out wrong. The answers were rated by random lookers, so the correct answers often got fewer votes.

Can the two species coexist with each other, or do you think the Eucalypts will one day crowd out the redwoods. This could be a disaster in the making if that where the case.

I was also wondering if there are any tall E. regnans and L. tulipifera found growing somewhere along the west coast? Thx.
