Victor Rodriguez Cruz braved an imminent storm to reach the pinnacle of a limestone hill, where a Palo de Rosa emerged from the Earth. Just beyond the tree, he peered at a valley where a bustling city on San Juan Bay had all but erased a once pristine, wild forest. “When a tree is lost, it is lost forever,” he said as he admired the Palo de Rosa’s verdant, glistening leaves.
Rodriguez Cruz manages the Natural Resources Conservation Program at Fort Buchanan, a United States Army Reserve-funded Installation near San Juan, Puerto Rico. In his role with the Directorate of Public Works’ Environmental Division, he leads the charge to protect the Palo de Rosa – one of the island’s most endangered trees.
Named for the distinctive red hue of its heartwood, the Palo de Rosa is indigenous to the limestone hills, or “mogotes,” of Puerto Rico and Hispaniola. The United States Fish and Wildlife Service declared the Palo de Rosa to be endangered in March of 1990, when only nine trees remained in the forests of Puerto Rico.
Rodriguez Cruz pointed to a resilient tree. “They grow only on the tops of these mogotes. Is that their preference, or are those populations the only populations that are left?” he asked.
Under the canopy, he chronicled the rather somber history and unusual biology of the Palo de Rosa.
Its decline, he said, could be attributed to many factors.
Deforestation and urban encroachment have decimated the Palo de Rosa’s natural habitat.
In addition, the Palo de Rosa’s reproduction cycles are erratic, at best. Biological studies indicate that the tree may be a “mast flowering” species, or one that produces an abundance of fruits in some seasons but no fruits in other seasons.
Seed dispersal is also a challenge for the Palo de Rosa. The Palo de Rosa may be an “outcrossing” species, requiring the cross pollination of individual trees. Since its populations are so limited, the pollination process could be very difficult. Furthermore, the fruits of the Palo de Rosa resemble the fruits of trees pollinated and dispersed by bats. Any absence of bats, or other pollinators, could have contributed to the tree’s demise.
Fort Buchanan is one of the few places on Puerto Rico where the Palo de Rosa thrives today. Still, only 12 Palos de Rosa live on Fort Buchanan. According to Rodriguez Cruz, the trees at the Installation are some of the only trees on the island that are currently producing viable seeds.
Fort Buchanan, the United States Fish and Wildlife Service and the Puerto Rico Department of Natural and Environmental Resources hope that these seeds are seeds of change.
In 2009, a Memorandum of Agreement between Fort Buchanan, the Fish and Wildlife Service and the Puerto Rico Department of Natural and Environmental Resources incorporated provisions for the protection of the Palo de Rosa into the Installation’s land use management plans.
The Fish and Wildlife Service uses Fort Buchanan’s trees to collect seeds to propagate the Palo de Rosa, enhance the Installation’s population and introduce them to other viable areas of the island. The Service also visits Fort Buchanan annually to monitor the health of the trees.
Fort Buchanan’s Directorate of Public Works has implemented numerous conservation measures as well. Reforestation has improved the environment for the Palo de Rosa and the post’s other endangered species, the Puerto Rican boa. The Directorate restricts access to the Palo de Rosa’s habitat, evidenced by prolific gold signs that relay a message of caution to Fort Buchanan’s residents. If necessary, the Installation limits the scope of military activity in those areas. They have eliminated the use of herbicides near the habitat. In addition, Rodriguez Cruz and his colleagues consistently educate Soldiers, Civilians and Families about their Installation’s unique tree.
Rodriguez Cruz crouched in the leaf litter to assess a tree’s roots. “Ultimately, we want to recover the populations of the Palo de Rosa so that the Fish and Wildlife Service can remove the tree from the Endangered Species List,” he remarked.
The loss of any tree would impact the survival of the Palo de Rosa, but Rodriguez Cruz believes that the loss of the species could broadly impact the culture of Puerto Rico.
“The Palo de Rosa is endemic only to the Caribbean, so the tree is a significant part of our natural heritage in Puerto Rico,” said Rodriguez Cruz. “Our natural heritage encourages tourism to our island, supports our economy and inspires our art.”
“Our flora could benefit us,” he continued, placing his hand on his chest. “Cures for cancers could be in these forests.”
Rodriguez Cruz regarded the Palo de Rosa once more. Then, he descended the mogote with the company of hummingbirds and lizards. He recounted Fort Buchanan’s important role in the protection of Puerto Rico’s special natural resources. In his voice, hope resonated – the hope that the Palo de Rosa will flourish with the spirit of the past and the hope that the Army Reserve can contribute to its future.
