3.8 Natural Resources: Per the Sheppard Air Force Base Integrated Natural Resource Management Plan (INRMP): “Contractors and base personnel will use necessary effective means to prevent construction related injury to trees and shrubs near construction sites.” In order to protect the trees and plants located within the project site that are not included within clearing areas, the following guidelines are provided:

1) On-site traffic which is required for construction activities should utilize existing roads to the maximum extent possible to prevent damage to vegetation/ground cover and trees which otherwise would not be disturbed.

2) Construction activities adjacent to vegetation, or in areas that do not require disturbance, should be conducted to prevent unnecessary damage to the vegetated areas. ALL vehicle operators should be made aware of vegetated areas in which construction and/or transport activities are not to occur. Physical barriers such as fences or barricades around individuals or groups of trees or plants can be used.

3) Material stockpiles or equipment storage should not be located within vegetated areas that are not already slated for alteration. Per the INRMP: “Vehicles or equipment will never be parked within the drip line (outermost circumference of a tree canopy) of any tree.”

4) Trees and vegetative matter that require removal in order to complete contract requirements should be removed without damage to adjacent trees and plants. Trained personnel should conduct such removals.

5) Existing trees cannot be used as anchors for any activities occurring on-site. Trees that are not slated for removal cannot be used for the placement of signs, placards, hooks, or any similar devices that would injure the tree. Limbs of trees that are to be retained shall not be used for the hanging of any materials. When possible, excavation within the root circumference of trees that are to be retained should be avoided.

*Trees to be retained that are damaged unnecessarily during construction activities should be repaired or replaced per the INRMP at no expense to the government.

Trees and shrubs located on or near the proposed construction site that are removed will be replaced in accordance with the INRMP tree policy. If a tree less than 10 inches diameter at breast height (DBH) has been slated for removal, it will be replaced on a two-for-one basis, using trees greater than 2.5 inches DBH. Trees greater than 10 inches DBH will be replaced on a three- for-one basis using trees greater than 2.5 inches DBH. The cost to relocate, replace, or remove trees located on a proposed facility construction site will be funded as part of the supporting utilities.

Replacement trees will be chosen from the INRMP list of approved trees.

The contractor shall avoid the take of non-game birds and migratory birds, their young, and their nests, in compliance with the Texas Parks and Wildlife Code Title 5: Wildlife and Plant Conservation, Subtitle B, Hunting and Fishing, Chapter 64, Birds Subchapter A: General Provisions.
