Yes, there are many rare and beautiful species and
ecological remnants on this isolated island. And yes, some are
severely threatened. And, admittedly, in two weeks we learned only so much. But
we noticed parallels to the Midwest that suggested unexpected potentials and challenges for Cuban conservation.
Endemics are species found nowhere else on earth. Cuba has 63 endemic amphibians, 24 endemic mammals, and more than 3,000 endemic plants. (By comparison, surviving endemics in the British Isles include 0 amphibians, 1 bird, and fewer than 20 plants.)
Our trip focused on birds. Of Cuba's 26 endemic bird species,
we saw 23 – quite a testament to our Cuban guides. For many species, a person
needs to know just where to go; the populations are small; and the sustainability
of the habitats appeared dubious. In many cases, development didn’t seem to be
much of a threat. Invasive plant species did, and yet there were little
or no resources for (or apparent interest in) combating them.
One disappointment was how much of our time we spent looking for birds on roadsides and other artificial habitats. Perhaps it was just easier to find them there, but we often got the sense that the habitats just back behind the edge were poor.

The bee hummingbird survives in
small areas widely scattered over the island. Found most frequently “in forest
edges with an abundance of shrubs and flowers,” it was seen by us only twice - first in a newly cleared roadside and then along a half-built boardwalk among new tourist cabins. In other words, we found it in temporary,
artificial habitats. We thought of the Midwest’s red-headed woodpecker that lost its natural savanna habitat, then was
common for two centuries around farms and yards, but is now said the be the
fastest declining bird in North America. Artificial habitats typically change,
unsustainably for some of their species. In the U.S. we're restoring savanna habitat - to the benefit of red-headed woodpeckers and thousands of other species. Should the restoration of quality habitat be more explored in Cuba?

are still fairly common
including the Cuban oriole, yellow-headed warbler, and the Cuban tody (left).

This rickety platform provided some of our best birding. But a closer look at the habitat raised questions. |

In many places, we saw vast landscapes covered with monotypic stands of a Chinese shrub that seemed to have little habitat value. We saw infestation of Australian pine (Casuarina) and paperbark tree (Melaleuca) that would scare us if we saw them in Florida. These species can wipe out all biodiversity on land theoretically "preserved" for conservation. But when we'd ask about these infestations, we got no clear response.
A similar assessment assessment struck me in Nils Navarro's fine book, Endemic Birds of Cuba. Navarro devotes a page and a half to the threats Cuban birds and other animals face. He lists out-of-control fires, excessive rains, droughts, hurricanes, habitat destruction as a consequence of urbanization, development of the sugar industry, tourism, mining, tree cutting, poaching for food and the pet trade, cats, dogs, pigs, mongooses, African sharp tooth catfish, and pesticides. Invasive plants are apparently not seen as enough of a problem to mention. Or perhaps they don't seem worth mentioning because the challenge goes too far beyond Cuba's resources?

We saw many plows pulled by oxen, none by tractors. People work hard. They don't have a lot of extra resources. |
In rural areas, few people had cars. These folks are passing a sign marking the site of the battle of the Bay of Pigs invasion. |
In big cities, some people have 60-year-old American cars.
But in the smaller towns, most people travel by bicycle, horse, or bus.

Blue-headed quail dove. Extremely rare. Rapidly diminishing. (KN) |
We saw the blue-headed quail dove in two areas. In both it had been baited with bird food. According to Navarro, it is illegally hunted as a delicacy. Despite a range of 11,000 square miles, there are estimated to be only one or two thousand birds left. That would be one or two birds per thousand square miles. Good habitat can support 20 per acre. What is good habitat? Are there forest management or restoration practices that would benefit this and other rare forest birds?
We found Fernandina's flicker plentiful in one small area. Navarro says that 600 to 800 survive. Estimated habitat for the flicker is 2,800 square miles. Clearly, not all the habitat is as good as the little area where we saw them - a beautiful "fluvial savanna." It had clearly been burned recently. Our guides seemed not to know why - or whether burning helps this species (or for that matter the "near threatened" Cuban parrot, which sometimes nests in the same tree with it). Research on habitat management needs of rapidly declining species could pay big dividends.
Dr. Orlando Garrido, Cuba's foremost living naturalist, took time to welcome and orient our little delegation. |
Many Cubans we met were deeply committed to conservation. But resources are tight. Many Americans would eagerly go to Cuba to help with research and restoration, help find conservation grants, etc. That won't be easy, given the politics, though ambitious attempts could be well worth the effort, if the U.S. continues to relax its punitive restrictions. Perhaps non-antagonistic countries that have advanced restoration expertise could be helpful. South Africa and Australia come to mind. Would Cubans from the cities or countryside volunteer, as many do elsewhere - if facilitated?
In the central U.S., for decades, American conservationists made a mistake. We focused too much on removing human influences. "Preserving" land - blocking development - was our principal conservation strategy. At least in the midwest, we now know that loss of habitat quality on protected conservation land is at least as big a cause of biodiversity loss. We have to conserve land, yes, but then we have to maintain habitat through controlled burns where needed, invasives control, and hydrology and species restoration. If American and Cuban conservationists could collaborate on such questions, it would likely be popular among both of our peoples.
NOTES
1. All photos taken by fellow trip-mates. Thanks to Kim Novino (KN), Ron McAdow (RM), Linda Masters and Stephen Packard.
2. We deeply appreciated the generous Cuban conservationists who led the trip, especially Dr. Luis Diaz of the Cuban Natural History Museum. Also Osmani Borrego, administrator of Guanahacabibes National Park.
3. We did find an exception to our impression that development was over-rated as a threat. On the barrier island of Cayo Coco, glitzy resorts are rapidly replacing habitat. Nearby Cayo Romano seems likely to lose much of its nature soon. Development could soon spell the end of its Cuban black hawks, thick-billed vireos, Cuban gnatcatchers, Bahama mockingbirds, and Cuban sparrows.
Cayo Romano was nearly all wild - and rich with rare shrubland plant and animal species. Much of it is soon likely to be overrun with resorts. |
4. Our trip was organized by Massachusetts Audubon Society and the Caribbean Conservation Trust. Special thanks to trip leader Bob Speare.
5. We also saw eleven species of birds endemic to the West Indies - some of which are quite common in Cuba - including the great lizard cuckoo, Antillean palm swift, Cuban emerald hummingbird, and the red-legged thrush.
Thank you for a peek into Cuba. I thoroughly enjoyed seeing the photos of life in Cuba and the gorgeous birds. Your writings are thought provoking.
ReplyDeleteYou were lucky to partake in such an endeavor. Thank you for sharing your experiences.
ReplyDeleteHow did this delegation benefit the local people so they would continue having a stake in conserving the rare species of their country?
I hope we helped. Here are some possible ways.
Delete1) We exchanged a lot of ideas with the local conservation leaders; they were very proud to show off their areas and describe their efforts.
2) We spent money of food, lodging, guides, etc. The fact that nature brings some revenue impresses some people.
3) I think they can learn from us and we can learn from them.
I am sure your delegation both disseminated valuable ideas to conservation leaders and helped give local residents a stake in conservation. Such actions as spending money on food, lodging, guides, and passing along your great experiences to others are often the things that tip the balance toward local support for conservation. Many stewardship groups in the Chicago region help build local support by going out to eat after a workday which also has the added benefit of giving volunteers an opportunity to socialize.
DeleteGreat photos! Thanks for keeping hope alive.
ReplyDeleteLooks like a great trip. Too bad about the unsustainable habitat, but sounds as if it was a good idea exchange with local naturalists.
ReplyDeleteLooks like a fantastic trip. Cuba also as wonderful endemic butterflies. I've alwatys wanted to see Gundlach's swallowtail.
