      I have a grove of about 500 native Florida switenia mahogany trees
      in homestead florida south west of miami .
      trees are around 18 years old , 25 foot tall , 8 inch caliper ,
      Ambrosia betels are devouring the trees a dozen dead ,
      another 50 sevearly infested local arborist agree that the beetles are probably secondairy ,attacking stressed trees,
      yet no one has an idea what the primary stress is .
      Any thoughts ?

    Michael,
    As a forester that recently relocated to Florida, I’ll share my thoughts on the question you posted earlier this week.

    Might this site have a low nutrient level, be subject to seasonal flooding or have a very high water table such that the roots are often deprived of oxygen? Is the soil on the site in its natural state, without disturbance by man? Deep mixing of the subsoil with the original surface can affect the ability of plants to thrive. Any of these could be a primary stressor for your trees.

    Here are some links on the cultivation of switenia mahogany trees you may find to be helpful. (Links are not ‘live’ in this response. To view, cut and paste one address at a time into your browser’s address line to visit).
