Susan and I had a chance to spend about three weeks in Spain during late October and early November of 2014. I occasionally took time measure some trees. Some of the larger examples of species seen are listed below.
Madrid: In front of the Prado Museum was this Deodar Cedar (Cedeus deodar[i)] pictured below:

The drive between Seville and Ronda was most interesting. Several hillside "White" villages, extensive stands of Cork Oak forests, and the Sierra de Graalema Natural Park.

The park is 127,000 acres and has been a Biosphere Reserve since 1977. It is in a karst area with the highest mountain at 5,426'. The park also has extensive stands of Spanish Fir(Pinus pinapso) although most of what we saw were young and possibly results of restoration efforts.
