Spider Monkeys in Costa Rica. Going, Going...Gone?

     Costa Rica lost up to half of its monkeys in the twelve years between 1995 and 2007 according to ecologist Ronald Sanchez from the University of Costa Rica.  Of the four indigenous species (squirrel monkeys, spider monkeys, white-faced capuchins, and howler monkeys), the spider monkey was the most affected, with a 72% decline in population from 26,000 to 7,225 individuals.  And that was five years ago.

      "The  principal factor that reduces the populations is always sooner or later the deterioration of habitat," said University of Costa Rica researcher Gustavo  Gutierrez.  A growing number of developers are taking over their  jungle habitat, isolating them in small communities by fragmenting their habitat. This also inhibits the genetic diversity needed to keep them healthy, according to Gutierrez.  "What we have is 25 percent of the country in islands, without genetic contact between one island and another," Gutierrez said.

    According to Sanchez, in order to restore the populations, protected areas will have to be increased, and corridors will have to be created to reconnect the ioslated areas.

    Time is passing. And in addition to loss of habitat, spider monkeys are still being hunted.  Both Chiquito and Lolita were orphaned when their mothers were killed for bush meat.  Throw the illegal pet trade into the equation.  And the question becomes:  "Will there be any spider monkeys left to re-populate with?"

       Jane Goodall has always been my hero, and working with primates an aspiration.  Africa wasn't in the cards the summer I turned 16, when my parents offered to send me to volunteer,  and there was only one class (in physical anthro-pology) when I wanted to study primatology in college.  
         Decades later my husband and I retired in Costa Rica, and this is our journey with spider (and howler) monkeys.
