Plant Wonders--10 Tropical Plants Not to Miss

Looking into the Costa Rican rainforest

Ew! The tropics! Deadly snakes and poisonous plants! I tip-toed through the vegetation as if every leaf would bite!

I first encountered the tropics in 1973, when I took an Organization for Tropical Studies course, Tropical Ecology, which introduced U.S. graduate students to the tropics, in Costa Rica. At the beginning of the course, they gave us a safety orientation: these snakes are poisonous, these ants have a sting that will incapacitate you, these leaves cause welts...

Suitably intimidated--having experienced only the northern United States--I stayed in the middle of the path and tried not to get close to the leaves.

Visiting Costa Rica—A Rainforest Walk

My Betchart/Lindblad expedition last month took me to Costa Rica (see earlier post). We sailed north along the Pacific Coast, stopping at Corcovado and Manuel Antonio National Parks, before disembarking to fly home from San Jose.

I first visited to Costa Rica in 1972, with the Tropical Ecology course of the Organization for Tropical Studies, did Ph.D. research there, and have been back several times since. 

Costa Rica is about the size of West Virginia. Within that small space it is very diverse. The mountains down the center create a whole series of different ecosystems, varying in temperature and rainfall and more. There is tropical rainforest on both the Atlantic and Pacific coasts, but, cut off from each other by the mountains, they have different plants and animals. On the Pacific side in the northern half of the country, severe drought from December to June combined with heavy rain the rest of the year has created a distinctive tropical dry forest. 

In Costa Rica's southwest corner, I had a terrific time hiking in the lowland rainforest at Corcovado National Park.
