A Year in Uruguay

After staying in Cabo Polonio this July, we visited the nearby Monte de Ombúes.

An ombú is a native tree closely associated with gaucho culture and Uruguay's history. My mental image of an ombú has been a large, solitary tree surrounded by grasslands. (Not that I'd ever seen that; my actual experience with ombu trees was mostly of one particular tree growing in the middle of Boulevard España in Montevideo and a few others growing in city parks.) Ombú trees can have peculiar shapes with multiple trunks, merging branches, and frequent hollows.

The Monte de Ombúes promised something rare-- a forest of these unusual trees. The woods are on the shore of the Laguna de Castillos and the only access is by boat. Regularly scheduled tours depart from the bridge where the highway crosses the arroyo Valizas. Since July is the middle of winter in Uruguay, we were able to have a private tour.

Our boat floated slowly past pastures dotted with butia palms while gulls and egrets flew overhead. It's a great trip for birdwatchers; our guide pointed out ibis, teru-teru, chajá, cormorants, ducks, herons, kingfishers, and even flamingos. After about an hour, we reached the woods-- two groves of ombúes.

The trees themselves were impressive. Since it was winter, they were nearly leafless, focusing our attention on the trunks. Some of the trees were over 30 feet around and many had openings big enough for a person, or even a whole family, to enter. It was almost surreal seeing two trunks emerge separately from the stump and then recombine 10 or 20 feet higher.

This strange growth pattern is part of the ombu controversy: "Is it a tree or a shrub?" Until this visit, I'd always taken the tree side. The shrub argument seemed like it must be based on some obscure botanical definition. (Similar to the argument: "Is a tomato a fruit or a vegetable?") Based on everything I'd seen earlier, the ombú was a tree-- tall, solid, long-lived, trunk & branches, with leaves that dropped seasonally. How could it not be a tree?

Now I'm less sure. In the forest, we saw fallen ombúes and they weren't like fallen trees. Instead of being made of wood, the inside of an ombú looks like a cross between particle board and paper mache. Definitely not tree-like. New sprouts from the broken stumps furthered my confusion since they looked identical to the pokeweed that grows in my backyard in Michigan. The shrub proponents do have a point.

In any case, it was an interesting place to see. It's definitely a low-key trip-- something for nature-lovers; it would appeal to those Florida vacationers who choose Ding Darling over Miami Beach.
