Broken Boughs

Predatory winds have taken their toll this winter. Recent damage in Prospect Park, broken limbs destined for the chipper.

Why do trees die?
Trees die because respiration terminates.
Respiration terminates because carbohydrate production ceases and stored carbohydrates are exhausted.
Carbohydrate production ceases because photosynthesis discontinues.
Photosynthesis discontinues because the factors necessary for photosynthesis are interrupted or obstructed.
Factors for photosynthesis are interrupted because of human activities or environmental changes.
