I figure that there are around 200 old rubber trees (Hevea brasiliensis) on the Bosque Santa Lucia property. Most of them have been around for many years, maybe 50-70 years. I discover these two trees off a trail just last week. What impressed me were the very deep cuts on the trunk of the tree, much deeper than would normally be allowed in any rubber tapping operation. And they seem to be more recent, so I calculate that some woodman or tour guide is responsible.
