What plant feature does 'elevation' specifically help increase?

Elevation specifically helps increase sunlight accessibility underneath the canopy. In forestry and landscaping, as the elevation of a plant increases, particularly for trees and larger shrubs, it allows more light to penetrate the lower layers of foliage. This is crucial for the health and growth of plants that are situated underneath or around taller plants.

When the upper canopy is raised through practices such as selective pruning or allowing the natural growth of taller plants to take place, it can significantly improve the quantity of sunlight reaching the lower branches and ground plants. This increase in sunlight accessibility leads to enhanced photosynthesis for undergrowth and lower canopy plants, promoting their health and growth.

While aspects like soil nutrient content, overall plant height, and branch health may be influenced by elevation in broader terms, the direct relationship between elevation and light penetration makes sunlight accessibility the most relevant feature associated with elevation changes in this context.
