Roots and trunks may disturb structures and foundations.
• Limbs and trunks may fall and damage structures.
• Vegetation that is close to structures may increase the risk of damage by fire. (This depends on the type of vegetation eg
conifers with high oil and resin content carry a higher fire risk than deciduous, broadleaved species.)
• Structures may be smothered and dismantled by vegetation.
• Oversized vegetation can interfere with the intended scale of the landscape (eg trees planted next to a house may have
grown far larger than was originally intended, and may now dwarf the structure and other features).
• Vegetation may shade structures, increasing dampness and thereby increasing the rate of degradation.
• Vegetation may alter the moisture content of soil adjoining or underlying structures, resulting in movement of foundations,
walls etc.
• Vegetation may obstruct views and sightlines into, out of and within a landscape.
• Vegetation may suppress other nearby vegetation through shading, smothering and competition.
