If any of the named perils of fire, lightning, explosion, riot, civil commotion, or aircraft cause damage to outdoor fences, radio antennas, television antennas, satellite dishes, detached signs, or trees, shrubs, and plants, up to $1,000 applies to the loss, including debris removal expense (no other debris removal coverage is available for these items). As regards trees, shrubs, and plants, payment is restricted to $250 per item up to $1,000. These limitations do not apply to “stock” of outdoor trees and such stock is treated as “covered property.” Indoor trees, shrubs, and plants used for decoration are eligible for the full coverage of the forms both as to covered perils and as to insured values. These limits may be increased by endorsement.
