World Wildlife Day 2015

Standard

Today is World Wildlife Day 2015, which this year highlights the challenges of the illegal trade in wildlife.

World Wildlife Day, on the 3rd of March, marks the day of the adoption of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

The global trade in wild animals and their body parts is estimated by UNEP at US$50-150 billion per year. The global illegal fisheries catch is valued at US$10-23.5 billion a year and illegal logging, including processing, at US$30-100 billion.actionposter_thumb_elephant

These numbers don’t include the costs of fighting poaching, the impact that fight has on local communities, or the indirect costs of border security – after all, 90% of all illegal animals and animal parts are shipped across international borders.

These numbers don’t include issues like the introduction of non-native species in the form of exotic pets and the havoc they can wreak on local eco-systems (not to mention the introduction of foreign pathogens).

They don’t include the cost of fighting the organized crime that is funded via illegal wildlife trade.

What can each individual do besides sign a petition, make a donation or offer support today at #SeriousAboutWildlifeCrime?

As I said in an earlier post on ivory, we can cut of the trade on the consumer end. That saltwater fishtank might be a nice conversation piece, but the fish in it were likely harvested at the cost of an entire coral reef habitat.

Find sustainable alternatives to traditional medicine that calls for endangered species like pangolin or rhino (after all, people have been substituting buffalo horn for rhino for years).

That supposedly antique ivory trinket was probably made from poached elephant tusk. If that hardwood lumber for your floors is being sold at a price too good to be true, chances are its been illegally logged. And so on.

What you buy as a consumer ripples out through the entire environment of the illegal wildlife trade.

I thought I’d repost Farewell, Forest Symphony, something I wrote a couple of years ago on the interconnectivity of one single endangered species, the elephant, on its entire ecosystem.

It’s not a short post – but what is true for this particular animal is true in other ways for all the other endangered animals and plants:

They, and we, are all part of something larger.

The fundamental chords that hold a symphony together aren’t always apparent to the untrained ear. The symphony of an ecosystem is often more complex than we comprehend.

A recent study draws a vital connection between elephant poaching, tree reproduction and forest ecosystems. Certain trees – in this case, large bush mango trees – have evolved alongside large animals, in this case, forest elephants (Loxodonta cyclotis).

The trees have developed seeds which are best dispersed via elephants eating the seeds, walking long distances, and then depositing digested seeds far from the parent tree. The seeds of these trees are too large to be properly digested and dispersed by smaller mammals.

Unfortunately for both the wild trees and the elephants, up to 75% of the elephant population has been killed in the Democratic Republic of Congo (DRC), where this study was carried out, and an estimated 60% of all forest elephants in the world have been killed in the service of the illegal ivory trade – all in the last ten years.

From an interview in an article on Mongabay.com:

“[The] Congo forest without elephants would certainly lose part of its soul, but elephant extinction with their seed dispersal services would also affect the entire plant community,” lead author David Beaune with the Max Planck Institute for Evolutionary Anthropology told mongabay.com. Forest elephants are “important gardeners of the forest,” says Beaune, so important in fact that when elephants go extinct in a part of the forest, important trees are unable to reproduce. “If we can’t replace elephants, then the reproduction of these plant species is hugely compromised.”

The bush mango tree used in the study, Irvingia gabonensis, happens to be one that is also important to the economy of many African regions, and has been successfully cultivated. Its reproductive patterns are well-known.

It plays a key role in preventing soil erosion as well as being useful as a cash crop.
What of the many other fruits and seeds eaten by forest elephants which are less-studied, with lesser known roles in the ecosystem? Without the massive ‘gardeners of the forest’, what aspects of the ecosystem will crumble?
It puts me in mind of the final movement of Haydn’s Symphony No. 45, in which all the instruments disappear. There is a final song of the remaining violins, but it is thin and lonely without the other melodies.
