For regular readers of my blog you might already know my stance on the monarch, แต่ catch up here if you’d like to. Yesterday I came across บทความนี้ in the LA times – regarding the overwintering colonies of monarchs in Pacific Grove, ที่. Out here, west of the continental divide, there are quite a few monarchs that migrate to coastal California and Baja del Norte instead of traveling into central Mexico. Not all monarchs from California stay in the state, but there are dozens hundreds of known roosting sites (.ไฟล์ PDF) up and down our pacific coast.

Pacific Grove has one of the best known localities and has built the local economy around their seasonal migrants (yet no one is deporting these Mexicans). ในระยะสั้น, the town government hired an arborist to cut back dangerous eucalyptus growth. Why was that necessary? ย้อนกลับไปใน 2004 a limb from a diseased native-pine had fallen and killed an 85-year-old woman while on a walk with her grandchildren. In wake of the million dollar settlement paid to the family of the deceased the town decided to preemptively cut back old tree growth. But now everyone is running around screaming foul, the trees were trimmed ด้วย much. ใช่, the precious homes of the monarchs were disturbed and it has riled the townspeople into a fury. What if the monarch’s don’t return?

Don’t worry, local filmmaker Bob Pacelli has a solution. Let’s just scatter as many eucalyptus trees as we can find into the grove to attract more butterflies.

In desperation, Pacelli came up with a plan: Find boxed trees — preferably blue gum eucalyptus — around 20 feet high and place them at strategic spots to help shelter the incoming monarchs. But the city has been slow to respond, Pacelli said. One official, Pacelli said, wrongly accused him of stepping on a butterfly, a violation of city code. No charges were filed.

For those paying attention, ใช่, the city council of Pacific Grove has a law on the books that imposes a fine of $1,000 on anyone who molests a butterfly. Good things monarchs don’t roost in catholic churches.

Nowhere in this article is the obvious pointed out. Eucalyptus trees are NOT NATIVE to the United States. ใช่, they belong down under with koalas and shrimp on the barbie (ขอโทษ). The trees were introduced around 1853 in the hopes they would be a miracle tree for lumber and other products. เศร้า, no one tested the theories before letting the tree loose in our landscape, and it has become a dangerous pest. These trees evolved with fire and they have come to truly embrace it. The long peeling bark flakes off into floating torches that carry the flames to the canopy, and the oils within the tree are highly flammable – so much so that burning trees can literally explode. Here in California things that are extremely flammable are usually frowned upon, especially since most of our population lives in a tinderbox (seriously, a golfer last week set off a blaze when his club struck a rock and the spark couldn’t be put out fast enough!) Yet somehow the eucalyptus is protected in many cities. ใช่, it could cost you a fine of $500 just to remove a small tree in the city of Santa Cruz. Down in Santa Barbara, where I used to live for a few years, people rally by the thousands to save their precious eucalyptus. It seems to me that residents of places with more money and more sun have inversely fewer braincells to put to use. I did come across this one article (where I pulled the 1853 date from), that discusses the profane nature eucalyptus love. The author is on the right track, but I don’t think euc groves serve as “monarch sinks” – where butterflies roost only to be blown out to sea during winter storms. Extensive monitoring projects would have long ago pointed that out if it were the case.

So what did the monarchs do before 1853? That’s a hard question to answer since to my knowledge there are no reports of trees full of butterflies from early settlers. You would think that it might have been mentioned by someone like John Muir. แต่, one possibility is that the monarchs were here all along – just roosting in stands of Monterey pine and other natives. The pines don’t seem to have the same density as the eucalyptus, so these roosting colonies may not have been very impressive. Roosting may have even been limited to warmer years or when fewer storms pounded our coast. Possibility two is that the monarchs were NOT here in northern/central California before 1853. Most likely the monarchs roosted in the warm coastal areas of southern California and Baja – but with the introduction of the eucalyptus, capitalized on the better shelter tree and branched northwards.

So what should be done? I am all for the removal of eucalyptus statewide, including in the precious monarch groves. So what if the monarchs don’t reappear? อันที่จริง, this year would be one of the best to eradicate the eucalyptus because monarch numbers are down a whopping 90%! Fewer returning monarchs need fewer trees (there seems to be a logical fallacy implied above that having or planting more trees will attract more butterflies – ขอโทษ, if they are down 90% then all the eucalyptus in the world won’t attract more butterflies). Now would be the perfect opportunity to replace invasives with native pines. I will close with a quote by Ansel Adams, stolen from the article I link to above (the anti-euc one).

I cannot think of a more tasteless undertaking than to plant trees in a naturally treeless area, and to impose an interpretation of natural beauty on a great landscape that is charged with beauty and wonder and the excellence of eternity.
