Swietenia Macrophylla - Current Status

Current Status

Consumer demand for big-leaf mahogany has driven boom-and-bust logging cycles for centuries, depleting local and regional supplies from Mexico to Bolivia. Approximately 58 million hectares (21%) of mahogany’s historic range in South America (278 million hectares total) had been lost to forest conversion by 2001. Commercial populations had been logged from at least 125 million more hectares, reducing the current commercial range to 94 million hectares (34% of historic). Surviving mahogany stocks are extremely low-density populations in remote regions of Amazonia representing a smaller fraction of historic stocks than would be expected based on estimated current commercial range.

The following country-level descriptions of big-leaf mahogany’s current commercial range in South America are excerpted from Martinez et al. (2008).

Famous quotes containing the words current and/or status:

    I have come to believe ... that the stage may do more than teach, that much of our current moral instruction will not endure the test of being cast into a lifelike mold, and when presented in dramatic form will reveal itself as platitudinous and effete. That which may have sounded like righteous teaching when it was remote and wordy will be challenged afresh when it is obliged to simulate life itself.
    Jane Addams (1860–1935)

    Recent studies that have investigated maternal satisfaction have found this to be a better prediction of mother-child interaction than work status alone. More important for the overall quality of interaction with their children than simply whether the mother works or not, these studies suggest, is how satisfied the mother is with her role as worker or homemaker. Satisfied women are consistently more warm, involved, playful, stimulating and effective with their children than unsatisfied women.
    Alison Clarke-Stewart (20th century)
