California Leaf-nosed Bat - Human Impact

Human Impact

They are susceptible to human disturbance, which can be especially detrimental to the species during summer months, when these bats are rearing young. Human disturbance of caves in which they roost is a major threat. Furthermore, because they often roost in abandoned mines, reclamation practices and re-working old mines can severely impact populations. Because California leaf-nosed bats do not hibernate or migrate, the relatively warm mine shafts are critical for its survival in the northern portions of its range.

Famous quotes containing the words human and/or impact:

    Unless a group of workers know their work is under surveillance, that they are being rated as fairly as human beings, with the fallibility that goes with human judgment, can rate them, and that at least an attempt is made to measure their worth to an organization in relative terms, they are likely to sink back on length of service as the sole reason for retention and promotion.
    Mary Barnett Gilson (1877–?)

    Too many existing classrooms for young children have this overriding goal: To get the children ready for first grade. This goal is unworthy. It is hurtful. This goal has had the most distorting impact on five-year-olds. It causes kindergartens to be merely the handmaidens of first grade.... Kindergarten teachers cannot look at their own children and plan for their present needs as five-year-olds.
    James L. Hymes, Jr. (20th century)
