Umpqua NF Tree Release and Site Prep

The purpose of this item is to secure services for tree release and brushing treatments in such a manner as to release desirable tree seedlings from competing brush and to prepare sites for tree planting by cutting brush.

Location and Description

The location, access, and acreage of each line item, as well as other information pertinent to this item are contained in the Vicinity and Unit Maps. All units are located on the Umpqua National Forest, North Umpqua Ranger District. All units were burned in 2020 and may or may not have had salvage treatments. Units with salvage treatments will be specified in the Schedule of Items.

Unit conditions are highly variable and consist of a mix of potential brush species. Dominant brush species and potential cover are noted in the Schedule of Items, but may include Ceanothus velutinus (snowbrush), Ceanothus integerrimus (deerbrush), Cytisus scoparius (scotch broom), and Rubus armeniacus (Himalayan blackberry), among other potential brush such as hardwood resprout clumps. In addition, unit slope conditions may exceed 90 percent in some areas. Slope conditions are shown on the detailed unit maps. For visual examples of possible conditions that may be encountered, two photos have been attached showing cases of heavy brush cover of snowbrush in Unit 205 (Figure 1) and more extreme examples of slope conditions that may be encountered as shown in Unit 110

(Figure 2). These figures are meant to portray some of the more extreme conditions that may be encountered and are not meant to serve as an average representation of conditions across units.

Line Item 1.1: Brushing for Site Preparation (Site Prep) – Units may or may not have been planted. Stocking levels are expected to be under 150 trees per acre (TPA). Brushing will be used to prepare units for future planting.

Line Item 1.2: Tree Release – Units may or may not have been planted. Stocking levels are expected to be above 150 TPA. Brushing will be used to remove competing vegetation away from planted and naturally regenerating seedlings.

All units are within ¼ mile of Forest roads that are accessible by a standard two-wheel drive pickup equipped with snow tires and chains, if needed, during normal operating seasons.

Roads shown on unit maps indicate access to units and are not to suggest the roads are open within units or for any further travel.
