HONG KONG — A little more than a year ago, I wrote an article about the alarming pickup in the trade in endangered species that the world has seen in recent years.

A year later, the situation has, if anything, only worsened — and there is little prospect that campaigners and the enforcement authorities will be able to reverse the trend any time soon.

For those of you who do not follow the steady flow of wildlife-related news, here is a selection of some of the most striking events of the past year:

• Hong Kong customs officials in November seized 33 rhinoceros horns, 758 ivory chopsticks and 127 ivory bracelets, worth about 17.4 million Hong Kong dollars, or $2.2 million, from a container shipped from Cape Town.

• Hundreds of elephant tusks were seized by officials in China, Vietnam and Thailand, in three separate incidents in April alone. Hundreds more were intercepted last year in a series of seizures in Malaysia, which has emerged as a major transit hub for illegally trafficked ivory.
