A Man, a Plan, a Canal: Panama
Now read the title backwards. Asides this being a great palindrome, the country and the canal are amazing.
Barro Colorado Island
On our first day we sail about halfway up the 81 km long canal to visit Barro Colorado Isand (BCI). This artificial island came into being when the canal was constructed between 1910 - 1914. Before the Chagres river was dammed to form the high-level canal BCI was the top of a hill. Since 1923 studies on the rainforest ecosystem have been carried out on BCI. Consequently, it is now one of the most studies places on earth and has become a prototype for measuring the biodiversity of flora and fauna around the world.
Another great home for Tarzan
Together with US researchers that currently work on the island – currently administered by the Smithsonian Tropical Research Institute (STRI) - and experts of the Rainforest Foundation US we explore the island. It is absolutely incredible! We see howler monkeys, toucans, bats, agouti’s, deer, parrots, preying birds, leaf cutter ants, bullet ants (if they sting you it feels like you have been hit by a bullet), a sloth and much, much more.
Everywhere are little ribbons that mark research projects, and with 250-300 researchers a year, there are a lot. Interesting is that they have set asides a 50 hectare plot to monitor long term changes in the rainforest. On other tracks the canopy is totally covered in liana (the woody vines Tarzan swings on). Scientists are currently researching whether this has abundant growth of liana has an impact on forests ability to store carbon. I can’t wait to hear the outcome of that.
Here is the official video on BCI by the STRI with more information about it’s history and research projects.
Bats
After this invigorating walk we receive an equally interesting talk about bats by scientist Elisabeth Kalko. She explains us the important ecological role bats have in tropical rainforests. They are amongst others a source of pollination, seed dispersal and a natural pest control. Yet, what impresses us most are her slow motion footages of how bats navigate in total darkness. Via echolocation (and perhaps extraordinary eyesight) the can adjust their route last minute with about 40 miles per hour. Amazing to see!
In transit
On the way back to Panama City we pass a enormous containership just coming out of the locks on the Pacific Side. Every time a ship passes the canal, they are lifted up almost 26 meters by the locks. Yet, per lock-cycle going downward to the oceans 101.000 m3 fresh water is lost. With almost 15.000 ships annually, that isn’t very sustainable. Therefore sometime soon water saving basins will be installed next to the locks. They will each transit reuse about 60% of the water from the locks that would have otherwise been pushed into the ocean. A step in the right direction, since many species on BCI (flora as well as fauna) are very susceptible to drought. And we should do anything we can to protect this paradise on earth!
Did you know that the Pacific side is about twenty centimeters higher than the Atlantic side?
