Jack pines often die on sand hills due to a combination of factors, including poor soil nutrients and water retention. These trees are adapted to survive in sandy, well-drained soils, but when conditions are excessively dry or nutrient-poor, their growth can be stunted, leading to increased vulnerability to pests and diseases. Additionally, if there is insufficient fire disturbance, which is essential for their regeneration, their population can decline. Overall, the harsh conditions of sand hills can limit their ability to thrive and reproduce effectively.
